Most dining chairs are chosen on looks, and most complaints about them come down to numbers: a seat that sits too low for the table, armrests that hit the apron, or six chairs squeezed along a table made for four. A few measurements, checked before ordering, prevent all three.
The figures below are typical values used by furniture makers and interior designers. They are general guidance, not fixed rules, and every chair and table combination should be checked with a tape measure. You can compare them with the dimensions listed for each model in our dining chairs collection.
Seat height and the gap to the tabletop
A standard dining table is typically 74–76 cm high, with 75 cm the most common figure. For that height, dining chair seats usually measure 45–48 cm from the floor. The number that matters most is the difference between the two: a gap of roughly 27–30 cm between seat and tabletop lets your forearms rest on the table with relaxed shoulders.
- Gap under 25 cm: the table feels high and your shoulders lift while you eat.
- Gap over 32 cm: you lean forward and the table feels low.
- Upholstered seats compress by about 1–2 cm when you sit, so measure a padded seat with some weight on it, or allow for it.
If you already own the table, measure its height first and choose the chair from that number, not the other way round. If you are choosing both, compare the heights listed in our dining tables collection with the seat heights of the chairs you like.
Apron clearance and armrests
Many tables have an apron, the frame rail that runs under the top. What counts for your legs is the distance from the chair seat to the underside of that apron. A common rule is to keep at least 18–20 cm here, so thighs and crossed legs fit without touching. A table with a deep apron of 10 cm or more can feel tight even when its overall height is correct.
Armrests add a second check. Chair arms are typically 64–68 cm from the floor. If they are higher than the underside of the apron, the chair cannot slide under the table and stands out into the room when not in use. Many households use chairs with arms only at the two ends of the table and armless chairs along the sides, which saves space and keeps the sides easy to get in and out of.
Seat width, depth and back height
Typical dining chair seats are 45–50 cm wide; chairs with arms usually measure 55–62 cm across overall. Seat depth tends to sit between 40 and 48 cm. A deeper seat suits long dinners and taller people, but if it is too deep, shorter guests lose the support of the backrest or sit with their feet barely on the floor.
Back height changes both comfort and the look of the room. Overall chair heights commonly range from about 78 cm for a low back to 95 cm or more for a high back. A low back keeps sightlines open across a kitchen and dining space; a higher, fully upholstered back gives more support through a two-hour meal. As a rough check, the top of the backrest should not hide a window sill or a sideboard top that you want to keep visible.
How much table length each chair needs
A common rule is 60 cm of table edge per person as a minimum and 70 cm for comfortable dining. Chairs with arms need 70–75 cm each. On a 200 cm rectangular table this means six people comfortably, two on each long side and one at each end, or eight at a squeeze if the chairs are slim. Also check where the table legs stand, because a leg in the wrong place can cost you a seat.
Round tables follow the same idea along the edge. As typical values, a table of 110–120 cm diameter seats four comfortably, 140–150 cm seats six, and around 160–180 cm seats eight. A pedestal base helps here, because no corner leg gets in the way of knees. Our cover photo shows Rory dining chairs around a round table, a layout where compact chairs make good use of the circle.
Clearance around the table
Chairs need room behind them. A seated person needs about 75 cm from the table edge to a wall or another piece of furniture to push the chair back and stand up. If people also need to walk behind seated guests, plan for 90–110 cm. In practice, a 200 × 100 cm table for six needs a free area of roughly 380 × 280 cm before the chairs feel cramped. Our article on how circulation patterns influence furniture placement covers walking routes through a room in more detail.
Checking a chair before you order
When you compare models, write down these five numbers for each chair and hold them against your table:
- Seat height, and the gap it leaves to your tabletop.
- Seat height to the underside of the apron.
- Arm height, if the chair has arms.
- Overall width, multiplied by the number of chairs per side.
- Seat depth and back height, for comfort and sightlines.
At Sitdesign every chair is handmade in our own factory in Büyükçekmece, Istanbul. Each model in the collection, from the Rory to the Bellini dining chair, has its standard dimensions on its product page, and custom dimensions are available on request, for example a seat height matched to a table you already own. Upholstered chairs can be covered in genuine leather, in 76 colours across 12 colour families, or in fabric, and customer's own material (COM) is accepted.
Send us your table height, its apron depth and the number of seats you need, and we will suggest suitable chairs, send leather samples and prepare a quote. Contact us here.
