The height of a dining table and its chairs
Thirty centimetres between seat and tabletop, never more, never less
A meal is uncomfortable when the table is too high for the chairs. The thirty-centimetre rule is non-negotiable, and yet half of all mismatches get it wrong.
What gap should there be between the chair seat and the tabletop?
Aim for 30 cm (28 to 32) between tabletop and seat. Standards give it automatically: a 75 cm table with 45 cm chairs. This gap lets you rest your forearms without raising your shoulders and slide your legs under without your thighs hitting.
§ 01The principle
For a comfortable meal, the difference in height between tabletop and chair seat must be 28 to 32 centimetres. Standard dining tables are 75 cm tall, standard chairs are 45 cm seat height, giving a 30 cm gap, exactly right.
The problem starts when you mix tables and chairs from different sources. A chair at 50 cm under a 75 cm table: 25 cm gap, too small, thighs hit the underside. A chair at 40 cm under a 75 cm table: 35 cm gap, too large, shoulders rise.

Tabletop minus seat = 30 cm (± 2 cm)
Standard: 75 cm + 45 cm. Bar: 90 cm + 65 cm. Counter: 110 cm + 80 cm.
§ 02Putting it into practice
Measure the height of your table top (floor to surface) and the seat height of your chairs (floor to cushion, unweighted). If the difference is not 28-32 cm, you have an ergonomic problem.
For very tall people (over 1.90 m), a 78-80 cm table with 48-50 cm seat chairs is more comfortable. Many antique tables are at 72-73 cm: adapt the chairs accordingly.

§ 03Professional variations
Pierre Yovanovitch designs his tables to a strict 75 cm, with chairs engineered for prolonged comfort (padded seat, back following the spine). He considers a meal often lasts two to three hours: ergonomics is not a luxury.
Thirty centimetres between seat and tabletop, otherwise every meal is uncomfortable.
