17 inches. That’s the seat height of the mid century modern kitchen chairs I bought last spring. Sounded fine when I measured them in the store. Then I got them home and ate dinner with my chin hovering an inch above the plate. The table was 30 inches tall. Standard. The chairs were 13 inches of that. I was sitting in a hole.
Took me a month to admit it. I kept thinking I’d get used to it. I didn’t. My knees were up around my ears and my back ached by the end of every meal.
Don’t do what I did. Buy the pretty chairs, sure, but check the seat height before you hand over cash.
The rule is simple: seat height should be about 11 to 13 inches below the underside of your table. So if your table is 30 inches tall, you’re looking at chairs with a seat height of 17 to 19 inches. I ended up swapping mine for a pair with an 18-inch seat height. Totally different world.
Also, don’t forget the armrests. I learned this the hard way when I tried to sit a set of chairs with arms under my table. They didn’t fit. The arms hit the apron and I couldn’t pull in close enough to actually eat. If you’re buying chairs with arms (and those mid-century shapes often have), measure the gap between your table legs or the underside of the table top. There needs to be room for the armrests to slide under. Otherwise you’re eating at arm’s length.
And measure that seat height more than once on the floor, not on carpet. My living room carpet made everything look fine. Hardwood told the truth.
One more gripe: keep an eye on the seat width. A 20-inch wide seat sounds fine until you realize your hips are 21. I picked a narrow, sleek model and felt like I was sitting on a stool at a crowded bar. The ones I ended up with are 22 inches wide. Room to breathe.
So, before you order anything from a catalog or click through to a cart, get a tape measure. Measure your table height. Measure the chair seat height. Measure the armrest clearance. Then buy.
If you want a breakdown of other common misses, I wrote about the white kitchen chairs set of 4 mistake—how the gap between the seat and the floor is the thing you’ll actually notice. Or if you’re balancing chairs with a table, check what I learned about matching dining chairs and bar stools and the seat height rule.
And if you’re already in the middle of deciding between different looks, the first week with beautiful dining chairs is when you’ll notice everything I just said. Spend that week with a chair you can actually sit in.
Do this now: go measure your table. Write it down. Take that number with you when you shop. It’ll save you a month of slouching.
