1) Standard dining table height vs chair seat height

Most dining tables are 28–30" high. The chair seat height that fits best is typically 17–19".

Quick sizing table

Pro tip: If your table has a thick apron (frame under the top), measure to the bottom of the apron too. You’re buying for legroom—not just tabletop height

2) Seat depth: the comfort factor most people forget

Seat depth is how far you sit “into” the chair.

• 16–18" seat depth: most universally comfortable

• 18–20"+: lounge-like, but can feel deep for shorter users

A quick fit test: you want 2–4" between the seat edge and the back of your knees.

3) Chair width: how many chairs actually fit your table

Chair width determines capacity more than table length alone.

• Many dining chairs are 17–20" wide

• Upholstered chairs and armchairs can be wider

4) Back height & support: what to choose for real life

• Low/medium backs: lighter visual footprint (great for small spaces)

• Higher backs: often better for long dinners and posture

• Curved backs: usually feel more supportive than flat backs

5) Arms vs armless: comfort vs seating capacity

• Armchairs look premium and feel supportive, but reduce capacity

• Many customers choose armchairs for the ends and armless chairs for the sides
