Dining Chair Dimensions: Standard Sizes, Seat Height and Spacing
Overall and seat dimensions for side chairs and armchairs, the seat height that matches your table, and a spacing chart for how many chairs fit along each table length.
A standard dining chair is 17-22 in (43-56 cm) wide, 20-24 in (51-61 cm) deep and 32-40 in (81-102 cm) high, with a seat 17-19 in (43-48 cm) off the floor. That leaves 10-12 in (25-30 cm) under a 28-30 in dining table. Allow 24 in (61 cm) of table edge per side chair and 28-30 in per armchair.

Standard dining chair dimensions
Every dining chair has two sets of numbers: the overall frame, which decides how many fit around a table, and the seat, which decides comfort. Listings often give only the first.
| Style | Width | Depth | Height | Space at table |
|---|---|---|---|---|
| Compact side chair | 16-18 in 41-46 cm | 19-21 in | 30-34 in | 22-24 in |
| Standard side chair | 18-20 in 46-51 cm | 20-23 in | 32-38 in 81-97 cm | 24-28 in |
| Upholstered or parsons chair | 19-22 in 48-56 cm | 22-25 in | 36-40 in | 26-30 in |
| Dining armchair (captain or host) | 22-26 in 56-66 cm | 21-25 in | 32-40 in | 28-32 in |
| Windsor or spindle-back | 18-22 in | 20-24 in | 34-40 in | 26-28 in |
| Dining bench | 36-72 in long 91-183 cm | 14-16 in | 17-19 in | About 20-24 in per person |
Depth figures include back legs that splay out. A chair 23 in deep pushed fully under the table still sticks out a few inches, so measure from the table edge, not the wall, when checking a walkway.
How many dining chairs fit at a table
Count chairs per side with 24 in (61 cm) of edge per chair as the minimum and 28 in (71 cm) as comfortable, then add end chairs if the table is 36 in or wider. Corner legs eat into the first and last positions, so tables with pedestal or trestle bases seat at the upper end.
| Table length | Per side, tight (24 in) | Per side, comfortable (28 in) | Total with end chairs |
|---|---|---|---|
| 48 in 122 cm | 2 | 1 | 4 |
| 60 in 152 cm | 2 | 2 | 6 |
| 72 in 183 cm | 3 | 2 | 6-8 |
| 84 in 213 cm | 3 | 3 | 8 |
| 96 in 244 cm | 4 | 3 | 8-10 |
| 120 in 305 cm | 5 | 4 | 10-12 |
Round tables: divide the circumference (diameter × 3.14) by 24-28 in. A 48 in round table is 151 in around, enough for 5-6 side chairs. Table sizes for each seat count are in the dining table size guide.
A 24 in wide host chair at each end of a 36 in wide table leaves 6 in either side, which is fine. On a 30-32 in wide table, end armchairs collide with the side chairs. Check the table width before ordering a matched set with armchairs.
Matching seat height to table height
The gap between the seat and the tabletop should be 10-12 in (25-30 cm). Less, and thighs hit the apron; more, and the table sits at chest height.
| Table height | Seat height | Typical use |
|---|---|---|
| 28 in 71 cm | 16-17 in 41-43 cm | Low modern and many European tables |
| 29 in 74 cm | 17-18 in 43-46 cm | Common in older and imported tables |
| 30 in 76 cm | 18-19 in 46-48 cm | Standard US dining table |
| 36 in 91 cm | 24-26 in 61-66 cm | Counter-height table: use counter stools |
| 42 in 107 cm | 28-30 in 71-76 cm | Bar-height table: use bar stools |
For counter and bar heights, the bar stool size guide covers seat sizes and spacing.
Arm height and the apron
Measure from the floor to the underside of the table apron. Most aprons sit 24-26 in (61-66 cm) up. Dining armchairs have arms about 24-27 in high, so some will slide under and some will not. If you want armchairs to tuck in, buy ones whose arms are at least 1 in lower than the apron.
Seat comfort: what the inner measurements mean
- Seat depth 16-19 in: the right depth leaves 2-4 in between the seat front and the back of your knees. Upholstered dining chairs often run deeper, 19-21 in, which suits tall diners but pushes shorter ones forward off the backrest.
- Seat width 16-20 in: 17-18 in at the front of the seat suits most adults. Many chair seats taper toward the back, so measure at the front edge.
- Back height: a back 15-18 in above the seat supports the lower and mid back. Taller backs (20+ in) block sightlines across a room and make a table look crowded, which matters in open-plan spaces.
- Seat pitch: a seat that slopes 2-5 degrees toward the back feels more relaxed; a flat seat is better for eating upright.
Space to pull out a dining chair
A diner pushing back from the table needs about 32 in (81 cm) from the table edge if nobody passes behind, 36 in (91 cm) for someone to squeeze past, and 44 in (112 cm) for someone to walk past normally. These are the NKBA kitchen-planning figures, and they apply to dining rooms too. Room sizes for each table are worked out in the dining table guide, and the furniture dimensions guide collects the clearances for the rest of the house.
A rug under the table should extend 24 in beyond the table edge on every side, so chair back legs stay on the rug when pulled out. See rug sizes.
Outdoor and kitchen dining chairs
Outdoor dining chairs use the same seat height but are usually wider and deeper, 20-26 in (51-66 cm) wide and 22-26 in (56-66 cm) deep, because of thicker frames and cushions. A 2-3 in cushion raises the seat height by about that much, so check whether the listed seat height is with or without it. Stacking outdoor chairs are 18-22 in wide and allow the full chair count at the tight end of the spacing chart.
Kitchen chairs at a breakfast table are usually compact side chairs, 16-18 in wide. Where the table is against a wall or in a nook, a bench along the wall saves the 32-36 in of pull-out space on that side. For other kinds of seating, from office chairs to lounge chairs, see the chair size guide.
Frequently asked questions
What is the standard dining chair seat size in cm?
The seat itself is typically 40-50 cm wide and 40-48 cm deep, set 43-48 cm off the floor. Overall, including the frame, a side chair is 43-56 cm wide and 51-61 cm deep.
How far apart should dining chairs be?
Leave about 6 in (15 cm) between neighboring chairs, which works out to 24 in (61 cm) center to center for an 18 in side chair. For comfortable elbow room, use 28-30 in (71-76 cm) per chair, and keep chairs at least 12 in from the table legs at the corners.
How many chairs fit at a 72 in table?
Six comfortably: two on each long side with 30 in or more each, plus one at each end. Eight fit at 24 in per chair if the chairs are armless and no more than 20 in wide.
What size are outdoor dining chairs?
Outdoor dining chairs are usually 20-26 in (51-66 cm) wide and 22-26 in (56-66 cm) deep, with a seat 17-19 in high. Cushions add 2-3 in, so a chair with a cushion may need a frame seat of 15-16 in to end at the right height.
What seat height goes with a 30 in table?
18-19 in (46-48 cm). The seat should be 10-12 in below the tabletop, so a 29 in table suits 17-18 in seats and a 28 in table suits 16-17 in seats.
