How do you know if a dining chair will actually feel good to sit in?
It starts with getting the dimensions right. A dining chair that’s too tall, too shallow, or too tight for your space can turn even the best-designed rooms into a mismatch of form and function.
This guide breaks down everything you need to know, from seat height to spacing between chairs, so you can choose dining chairs that lookright andfeelgreat to sit in.
1. Start With Your Table Height
Most dining tables fall between 28 to 30 inches tall—a height that pairs best with chairs that leave about 10 to 12 inches of space for your legs.
Table height: 28–30 inches
Ideal seat height: 18–20 inches
If you need more legroom or want to use chair cushions, make sure you factor that in too.
2. The Right Seat Height Matters
Your seat height should give you space to cross your legs comfortably without bumping the underside of the table. The golden rule: seat height should be 10 to 12 inches lower than the tabletop.
If your table is 30 inches high, look for chairs with a seat height around 18–20 inches.
3. Choose the Right Seat Width and Depth
A comfortable seat gives you enough room to shift and settle in, without feeling squeezed or unsupported.
Seat width: 16–20 inches is standard (wider if you’re choosing armchairs)
Seat depth: 16–18 inches offers enough support for your thighs without forcing you to perch or lean back awkwardly
4. Check Backrest Height and Angle
Back support matters! Most dining chairs have a backrest height between 12 to 20 inches , measured from the seat to the top of the back.
For a more relaxed feel, look for a backrest angle of 10 to 15 degrees . It allows for better weight distribution and postural support.
5. Should You Choose Chairs With Armrests?
Armrests add support and structure—but they also take up more space and may not tuck fully under your table.
With Armrests
Pros:
Better comfort for longer meals
Easier to stand up from
Supports better posture
Cons:
Takes up more space
- May limit how many chairs fit around the table
Without Armrests
Pros:
Space-saving and flexible
- Easier to rearrange
Cons:
Less support for shoulders and arms
Not ideal for extended periods of seating
6. Don't Overcrowd: Chair Spacing Matters
Leave at least 6 inches of space between chairs to allow guests to move comfortably in and out. If your chairs have armrests or wider bases, increase that spacing so you can maintain elbow room.

Frequently Asked Questions
How do I measure the ideal height of my dining chair?
Measurement from the floor to the chair surface should be 10-12 inches (25-30 cm) below the height of the dining table, which ensures comfort during meals.
How do I determine the number of chairs to match the table?
Depending on the length of the table, there should be 12-24 inches (30-60 centimeters) between each chair to ensure that there is enough space for each guest.
Do I need to consider the height of the armrests?
If choosing chairs with armrests, the height of the armrests should be a few inches below the bottom of the table so they can be easily pushed under the table.
