How do you choose dining chairs that are comfortable for two hours, not just two minutes? Day 8 of the room challenge starts Week 2 with the piece you’ll feel most: the chairs. Seat height, width, depth and arms, measured the way I do for clients.

YOUR DESIGN GUIDE | ROOM CHALLENGE | DAY 8
Welcome to Day 8.
Week 2 starts today, and we start with the piece you’ll feel most: the chairs.
A dining chair can look perfect in a photo and still be miserable by dessert. Too low, too shallow, arms that bump the table. When guests linger at your table, it’s almost always because the chairs are comfortable.
So today we choose chairs the way I do for clients, with a tape measure first and the look second.
New to the challenge? Catch up on Day 5: Do the Table Math and Day 7: Keep, Move, Sell or Donate first.
Step 1: Measure your table first
Before you look at a single dining chair, measure two things on your table (or the table you’re planning):
- The height from the floor to the underside of the tabletop.
- The height of the apron, the band of wood under the top, if your table has one.
Write both numbers down. Every chair decision comes back to them.
Here’s the measurement that matters most, and it isn’t the seat height on the tag.
In this guide, you’ll get
- The Dining Chair Fit Guide with every measurement
- The 10 to 12 inch rule for the gap between seat and table
- How to check whether armchairs will slide under your table
- Chair widths and spacing, so everyone has room
- My rules for mixing chairs so they look planned, not random
The rest of Day 8 is for paid members. Read the full post on Substack.

Dining chair FAQ
What should I measure before buying dining chairs?
Measure your table first: the height from the floor to the underside of the tabletop, and the height of the apron if your table has one. Every chair decision comes back to those two numbers.
How much space should there be between the seat and the table?
My Dining Chair Fit Guide uses a 10 to 12 inch gap between the top of the seat and the underside of the table.
What seat height and depth are comfortable for a dining chair?
The fit guide shows a seat height of 17 to 19 inches and a seat depth of 16 to 20 inches.
What else does the full Day 8 lesson cover?
How to check whether armchairs will slide under your table, chair widths and spacing so everyone has room, and my rules for mixing chairs so they look planned, not random.
