What is the exact dining table size you need to create visual balance in your design?

Before starting your furniture search, you should calculate the range of dining table sizes that can fit in your room based on design principles, which can vary between round, square and rectangle table sizes. Besides considering how many people you want to seat, your dining table size also needs to allow enough space for people to pass, fit a dining setting, and be proportional to the room size to create visual balance.

If you need a quote for a particular dining table size, when you contact PAROTAS, we offer advice on the best table design for your space and seating requirements. You can also read how to calculate the ideal chair and table height, or see a list of standard bar and counter stool heights.

What dining table size should I buy?

Before deciding how many people you want to seat, you will need to see what size dining table will actually fit into the space you have, taking into account walls, walkways and other furniture.

To ensure you have adequate room around a dining table, you need a minimum of 30–36 inches (76cm) for clearance space, measured from the nearest obstruction, whether it be a wall, door, window or furniture. Although, a 30-inch space around your dining table size can still create a tight fit if people need to get up during the meal.

For a more comfortable space around your dining table size, opt for up to 42–48 inches (122cm), which also creates an elegantly proportioned room.

To ensure you don’t choose a dining table size that is too small for your room, don’t leave more than 6ft (183cm) from the edge of the room, at least on one side.

Best dining table size

When deciding on your ideal dining table size, consider that ‘less is more’ if you’re looking for a comfortable, spacious room. Taking into account these measures, you might find switching from a 10-seater to an 8-seater dining table size creates a better fit, for example, or from a rectangle to a round dining table size. Another option is to choose a table with fold-out leaves – ideal if you only host large groups occasionally – provided it still fits when expanded.

When deciding between a square, rectangle or round dining table size, your choice should be proportional to the shape of the room but also the amount you want to seat. For example, conversation can become difficult with tables measuring more than 7 feet wide (2m, similar to the distance that applies to the conversation area in a living room), which is what you would need if you’re considering a round or square table to seat more than eight. The bigger the table, the more dining parties are restricted to conversations with the person next to them, rather than across the table. In some cases, it can be better to consider an alternate shape, for example, a rectangle dining table size.

If you want to visualize the space your table will take, a tip is to place a sheet on the ground or create an outline with masking tape.

To give an example, in a room measuring 10 x 12 feet (3 x 3.6m), it would be possible to fit a rectangle table size of 36–42 inches wide (91–107cm) and up to 60–70 inches long (152 x 178cm), or a square or round table size of around 48 inches in diameter (122cm), allowing for additional furniture along one wall.

Dining table size compared to rug size

If you’re matching a table with a rug, you will need to make sure the rug is at least 30 inches longer than your dining table size on each side where there will be chairs.

If you use a rug 30-inches longer than your table – thus occupying the recommended space for free movement – then you should try to allow for at least 48 inches from your table to the wall to create visual balance.

Carpet rug size dining tableDining table height

Even though dining table designs vary considerably, the standard dining table height is usually pretty consistent. You need to ensure there is enough space for people to fit – and cross – their legs, without being too high that it becomes uncomfortable to eat. In general, you should leave at least 12 inches (30cm) between your chair seat and the tabletop.

Standard dining table heights range from 28 to 30 inches (71–76cm), which should be matched with a chair height of 18 to 23 inches (46–58cm, from floor to seat top), benches or stools. The shape of your table, however, can influence your chair and dining table height. Some tables have a support on the under side, which increase the distance required for legs.

If you’re considering a counter-height table, where people might stand or sit on high wooden stools, the standard dining table height is 34–36 inches (86–91cm) and should be used with chairs measuring 24–26 inches (61–66cm) from floor to seat.

If you opt for a bar table, standard table heights range up to 40–42 inches (102–117cm), with stools ranging from 28–30 inches (71–76cm). You can find more detail in our article about how to calculate your table and chair height, or how to calculate your bar and counter stool height.

what size dining table

Dining table size based on seating

Each person needs a minimum of around 24 inches (61cm) to eat comfortably, although some tables and chair designs (such as wooden benches) can allow more people to squeeze in when required. However, for a comfortable table surface, consider up to 28–30 inches (71–76cm) for more elbow room, especially if you have chairs with armrests or wide seats. In rectangular tables, you also need to calculate an extra 12 inches (30cm) for each end if you want to place seating at the head and foot of the table.

You will also need to consider the minimum depth required for a dining setting, plus some space for a shared area to place food, condiments or candles. To fit a basic plate setting allow for a minimum of 15 inches (38cm) deep, plus a minimum of around 5 inches (13 cm) for shared space (per person, or double for full table calculations).

To allow more room for your guests, as well as enough space for a full dining setting (including a bread plate and two glasses), then consider a table space of 30 inches wide (76cm) and 18 inches deep (46 cm), with a shared space of up to 9 inches (23cm) per person.

You be careful not to create too much distance, though; large round tables, for example, can make it difficult to reach food, while rectangular shapes can work better for seating large groups.  If you do opt for a round table wide than 60 inches in diameter (152cm), you might consider adding a lazy susan to your table design.

Using the above dimensions, a rectangular dining table size for six would be calculated at around 78 x 40 inches (203 x 102cm), or 96 x 54 inches (244 x 137cm) for a more comfortable setting.

If you don’t plan to put food or decorations on the table – for example, you have a side console table – or don’t mind moving glasses around, then there’s no need for calculating in shared space. If you sacrifice shared space, it’s possible to create a dining table size as narrow as 36 inches (91cm), which is still enough space to put a bottle of wine and some candles, while a sideboard can be used to serve food. In a restaurant, for example, you will often find tables around 36 inches wide (91cm) with very little sharing space.

Standard dining table size plate settingBefore calculating what size dining table you need, you need decide if you want to fit in extra seating at the head and end of the table.

What size dining table?

Dining table sizes vary depending on the furniture design. You may be able to fit more people by considering an alternate arrangement, for example, switching from a square to a round dining table.

Below you can see size requirements based on square, rectangle and round dining table sizes, and tips to help you choose which shape would work best based on the seating you want.

2 seater dining table size

The measurements for a two-seater square table need to account for shared space, putting the minimum dining table size at 31 inches (79cm), while a rectangle table for two would need at least 42 x 31 inches (110 x 70cm). If you opted for a 36-inch (3ft; 91cm) round table, however, you could comfortably sit up to three people.

4 seater dining table size

Round Dining Table Size

Round dining table size for four

The standard dining table size for four averages 36 to 40 inches (3–4ft; 91–102cm), although a 4-foot round table (102cm) can also squeeze six seats when needed.

While the minimum round dining table size for four starts at 36 inches, a pedestal base works best to allow more room. To allow more room for chairs and leg space, especially if there are table legs, the ideal round dining table size for four is 48–50 inches (4ft; 122cm–127cm).

Square dining table size for four

The ideal four-seater square dining table size is around 43 inches (3ft; 107cm). Similar to a round table, the minimum dining table size can be as low as 36 inches (3ft; 91cm), although you should allow more room – up to 50 inches (4ft; 122cm) – for a better fit and if you have wide table legs. Going up to 60 inches (5ft; 152cm) will allow you to choose between four to six seats.

Rectangle dining table size for four

The comfortable average to seat four is around 60 x 31 inches (152 x 79cm), although this rectangle dining table size could also squeeze six with the right table and chair designs.

To fit four diners on two opposite sides (ie. excluding head and table settings), the minimum area would be 48 inches long by 36 inches wide (122 x 76cm). To sit one diner at each end, the minimum space required would be 48 x 36 inches (122 x 91cm), or 60 x 55 inches (152 x 137cm) for the ideal, comfortable fit.

6 seater dining table size

Round dining table size for six

You will need at least 48 to 60 inches in diameter (4–5ft; 122–152cm) to seat six at a round table, working best with a pedestal base. It is possible to create a tight 6-seater round dining table with a diameter of 44–54 inches, but aiming for 54–­60 inches is a more comfortable fit and may even squeeze in eight.

The minimum round dining table size for six calculates to around 55 inches (140cm), although an ideal size would be 72 inches (6ft; 183cm). From about 60 inches (5ft; 152cm), you can start to squeeze in around seven to eight people, and with a minimal table design a 6-foot table could squeeze up to eight or nine when required.

Square dining table size for six

You will need at least 48 to 60 inches in diameter (4–5ft; 122–152cm) to squeeze in six at a square table (see table measurements for four and eight-seater tables).

Rectangle dining table size for six

It is possible to squeeze six people around a table measuring from 60–72 inches long (5–6ft) and 31–36 inches wide (152cm–183cm x 79–91cm).

To fit six without any diners at either end, the minimum dining table size for six would be 72 x 31 inches  (6ft x 2’6″; 183 x 76cm). To calculate enough space for diners at the head and foot of the table, the minimum size 79 x 36 inches (6’6″ x 3ft; 198cm x 91cm), although to avoid any overlap in dining settings you would need at least 96 x 55 inches (8ft x 4’6″;  244 x 137cm).

6 seater dining table size

8 seater dining table size 

Round dining table size for eight

The average round dining table size for eight is 72 inches in diameter (6ft; 183cm), although anywhere from 54–60 inches (5ft; 137–152cm) can fit six to eight people. Depending on the design, it is possible to squeeze seven to nine seats on round tables measuring anywhere from 5–7 ft.

The minimum required size is around 5ft (152cm), working best with a pedestal base or simple legs, otherwise the ideal size to allow a full plate setting would be around 7ft (213cm).

Square dining table size for eight

The minimum square, eight-seater dining table size is around 6ft (183cm), although 7ft (214cm) is the ideal size; both sizes, however, can squeeze up to 10 seats.

You could also squeeze up to 12 people around a 7ft table; for a larger square dining table size, you might a rectangular dining table so guests aren’t so far from each other.

Rectangle dining table size for eight

Dining table sizes for eight can range from 72 to 96 inches long by 36 to 43 inches wide (6–8ft x 3ft–3’6″; 183–244cm x 91–110cm), with the lower measurements also a comfortable fit for six seats and the higher measurements suitable to squeeze 10 people. The general standard you’ll come across, though, will be around 78 inches long by 36 inches wide for a eight-seater rectangle dining table size.

With a table of 96 x 29 inches (8ft x 2’6″; 244cm x 76cm), four diners can fit along each side, although you would need at least 103 x 36 inches (8’6″ x 3ft; 259 x 91cm) if you wanted to sit three side-by-side and two diners at each end. The ideal size for the latter arrangement, however, would be 127 x  55 inches (10’6″ x 4’6″; 323 x 140cm).

Dining table size 6 8 10 seater

A round dining table size can work well for six to eight people, as pictured above, but can get too large for conversation if you add space for 10 to 12 people.

10 seater dining table size 

Round dining table size for 10

From around 84 inches (7ft; 213cm), you very can fit nine to 11 people, while a 96-inch table (8ft; 244cm) could squeeze from 10 up to 12.

If calculating by plate setting space, the minimum requirement is 7ft (or from around 183cm), while a comfortable size calculates to around 8ft (244cm).

Square dining table size for 10

With the right table and chair design, you could squeeze 10 people onto a square table measuring from 6–8 foot in diameter. Although larger than 7ft and distances start to get a little far for reaching dishes, although a lazy susan can be added in.

Rectangle dining table size for 10

It is possible to fit 10 seats on a rectangle table size of 8–10 feet x 3’6″–4’6″ (244–305cm x 110–140cm).

To seat 10, five side-by-side, you should aim for a minimum length of 10 feet and width of 2 feet 6 inches (305 x 76cm). If you want to include a head and foot setting, aim for 10’6″ x 3 feet (323 x 91cm), or ideally 11′ 6″ x 4’6″ (354 x 140cm) for generous seating space.

8 seater dining table sizeWhen calculating if you can fit an 8 or 10 seater dining table size, you need to add extra space for the legs.

12 seater dining table size 

Round dining table size for 12

With a diameter of 8 feet (244cm) you can comfortably fit 10 people, or squeeze in 12 with slightly less elbow space, while you would need around 9 feet in diameter (274cm) to spaciously sit 12 people. With a 9-foot table, you could comfortably fit a range of 11–14 settings, while a 10-foot table (305cm) could sit 12 to 15.

However, with diameters larger than 7 foot (or around 200cm), conversation and reaching for food can start to get difficult, so you might consider a rectangular arrangement.

Square dining table size for 12

A table of 84 inches (7ft; 214cm) could fit 12, although a more comfortable fit would be up to 96 inches in diameter (8ft; 244cm), which can sit anywhere from 8–12 people comfortably. You might find the distance of an 8-foot table, however, interferes with conversation. It is sometimes recommended to consider a rectangular arrangement if you require longer than 7 feet.

Rectangle dining table size for 12

The smallest rectangle dining table size needed to fit 12 seats would be around 120 x 55 inches (10ft x 4’6”; 305 x 140cm), which would also comfortably sit 10.

To seat six side-by-side, the minimum space required would 144 x 31 inches (12ft x 2’6″; 366cm x 76cm). You can create a shorter table by seating two on each end, although would need a minimum size of 127 x 48 inches (10’6″ x 4ft; 320 x 122cm) or ideally 139 x 60 inches (11’6″ x 5ft; 350 x 152cm).

  1. Lisa says:

    Our room is 17 foot x 12 foot, what would you suggest is the maximum sizes table we could fit in, to seat between 12 and 14 people.
    Thank you

    • PAROTAS says:

      A rectangle table of 10–12ft long x 3–4ft wide could comfortably seat 10–12 people, depending on your desired seating arrangement. It would be harder to seat 14 people, but an option is to go for a wider table and seat two at each end.

      A round or square table of 7ft in diameter could squeeze in 12 people, but only allows minimal space for guests to enter and exit the table.

    • PAROTAS says:

      If there is no other furniture in the room, you could fit four people at a round or square table of 3ft in diameter (use a pedestal base for more leg space or to squeeze in five people). You could opt for a diameter of 4ft, although it will be a tighter squeeze to get into the table on two sides.

      You could fit a rectangle table of around 4ft long x 2.6–3ft wide, which seats around 4 people. Try to allow a space of around 3–4ft around each side of the table, so guests can move around (4ft is more comfortable).

  2. Darlene says:

    I have a dining space 12 ft by 13 ft. What is the largest table I can fit into this space so people can easily walk around the table. I don’t have any other furniture in the room.

    • PAROTAS says:

      You need at least 6–8ft of clearance space (counting both sides), so 7ft would be the longest table you could fit, but 5ft would be more comfortable for people to get in and out. You would then adapt these measurements depending on the shape (round, square, or rectangle).

    • PAROTAS says:

      A table with a length of 8ft–9ft would fit in the room, and you generally wouldn’t want more than 2.5–3 ft width for a rectangle table. You could also fit a round table with a diameter of 8ft wide, if you wanted to fit more people.

  3. Bridget says:

    Can you please tell me the centimetres around a 48″ x 88″ table as well as a 52′ x 88″ table? Will I lose place settings if I go with the 48″ x 52″? Many thanks!

  4. kim says:

    I have a space that is 12 feet wide by close to 110″ of useable space toward the kitchen island. I am considering a round 54″ table with 6 side chairs, rather than arm chairs so we will have more room. I would use 4-5 chairs for the most part and then add the 6th chair if we have company. Does this make sense for this space?

    • PAROTAS says:

      It makes sense, although you will have just under the minimum space for getting in and out of the table (30 inches on all sides), so in some areas it will be a tighter squeeze to get into the table. A 54 inch table is the minimum size to fit six people, so five people will sit comfortably.

  5. beth says:

    What size table would you recommend for a 14×24 dining room with a 20 inch buffet? Preferably max seating as we do entertain. Thanks

    • PAROTAS says:

      With such a large-sized room, technically the maximum size you can is fit 16ft x 8ft (assuming the buffet is on the longer side of the room), although those are not realistic measurements for a dining table. You wouldn’t want a round or square table wider than 7–8ft, because it creates sound issues, while 4ft is an adequate width for a rectangle table. So, most standard tables you buy will fit.

      Calculating in the maximum space to move around the table (48 inches), a 14ft-long rectangle table or 6ft square or round table would provide a nice visual balance.

    • PAROTAS says:

      Leaving a very narrow walk-around space of 30 inches, you could fit a 4-seater rectangular table of 48 inches x 24 inches, or a 2–3ft round or square table. Opt for a smaller table size if you prefer to leave more space to get in and out.

    • PAROTAS says:

      You could fit a square or round table of 5ft in diameter. With that size you could seat 6–8. Fitting 12 people would be unlikely. If you opted for a rectangular table, you could opt for a length of around 6–7ft, fitting around 6–8 people. You might be able to squeeze in two more people if you opt for a wider table, and seat two at each end.

  6. Paige says:

    Hello! I have a “nook” off of the kitchen in my new house that I’m planning on making our dining area. The nook is a square in shape and is 12 feet by 12 feet. I’m wanting to put a rectangular table there. What length table would you suggest?

    • PAROTAS says:

      You can fit a table with a length of 6ft (or even a square or round table with the same diameter), giving you around 36 inches of moving space on either side. You will also have plenty of space to opt for a table width that allows a full plate setting and room to place food in the middle (40–50 inches).

  7. TC says:


    I’m having a debate with my wife about what width table we should get. Our space is 173″ x 120″ with the short side open to the kitchen. We’re having an 8′ table made but not sure if we should get 36″ or 42″ wide. Any advice would be great. Thanks!

    • PAROTAS says:

      In terms of space, you can fit either 36″ or 42″, but your decision might be swayed by:
      1. The size or style of chair you have – if you have large chairs, opt for the smaller table size to give your guests more room to pull out their chair.
      2. Whether you use a full plate setting often, or if you want more room to set food in the middle of the table – in either case, opt for the larger table width.

  8. Janice R Russo says:

    I have a 11.5 ft by 11.5 ft dining room. What is the largest circular table I should purchase?
    Thank you

    • PAROTAS says:

      You can fit a round table of 5.5–6.5 feet in diameter, with seating for 8 to 10 people and minimal moving room.

    • PAROTAS says:

      It would be a tight fit width-wise, as that sized table would only leave around 23.5 inches to exit and enter the table on each side. The minimum recommended moving space is 30–36 inches on each side. If that doesn’t bother you, then you might consider bench-style seating or stools to help the lack of space.

    • PAROTAS says:

      Lengthwise, you could fit a table of 66-78 inches (5’5″ x 6’5″). Width wise, if you leave the minimum of 30 inches on each side to exit the table, you’re only left with a table of 30 inches wide, which doesn’t leave much space if you wanted to put food in between your plate settings. It would be unlikely that you could seat eight people. You could try a rectangle table with three seats on each side, and try squeezing two seats on either end when needed, but it would be a very tight fit and not comfortable.

  9. MMS says:

    I have a 15′ x 10’9″ dining room and I have the options of two different tables:
    48″ x 92″ or 42″ x 92″
    I would like to be able to seat 8 people comfortably with the option to squeeze in 10.
    Please advise…

    • PAROTAS says:

      If you want more room to put food in between plate settings, opt for the wider table (48 inches). If you want more space to enter and exit the table (or have larger style chairs, or with armrests), opt for the narrower table (42 inches). Both widths are comfortable for your room size.

      The thing you might reconsider is opting for a longer table. With 92 inches (7.6ft), you only just have enough space to fit in 8 people, but 10 would be tight. You could fit a longer table of around 9–10ft, given your room size, which would be more comfortable to seat 10. You might also consider a round table of around 6ft, which would be a tighter squeeze to get in and out on one side, but with a pedestal base, you it is easier to squeeze people in.

  10. Leigh says:

    My dining room is 10 x 14 with an 18 inch deep buffet across the 10 foot end. The opposite 10 foot end is a 4 foot opening to the foyer.What is the largest size table you would recommend ?

    • PAROTAS says:

      You could fit a table sized 95–105 inches x 30–42 inch, depending on how much visual space you want around your table (choose a smaller table if you want more visual space).

  11. Will says:

    I have a dining area of 7 1/2 ft x roughly 5 ft. although the 5 ft could extend into walkthrough area. Which would be a better fit round or rectangle and how big. I had a 3×5 rectangle previously with 4 chairs

    • PAROTAS says:

      Given our recommended entry and exit space (30 inches each side = 5ft), it is hard to recommend a table without seeing how the walkthrough area functions.


    If i have a large club ballroom that seats about 200 people at 10 – 12 ft round tables, would changing our tables to rectangles create more seating?

    • PAROTAS says:

      It would depend on the shape and size of your room. If you had a plain, rectangular ballroom, using rectangular tables would require less space to seat the same amount of people.

  13. Justin says:

    I have a 9.5’ x10’ nook surrounded by windows. Found a 60” round table i love with 4 fully upholstered chairs. Will this look too big for that space?

    • PAROTAS says:

      On one side it will be a tight fit and the other side will only have minimum space to enter and exit the table. It also depends on the room (if one side of the room is open there is more leeway, but not if it’s a closed room).
      It also depends on the type of chairs (chairs with armrests will take up more visual space), and the type of table (if the legs are thick or thin, or if it has a single pedestal base etc.).
