Set your office chair so your feet rest flat and your knees sit close to hip height, with your thighs roughly level. If the desk forces you to raise the chair, support your feet with a footrest.

There is no single seat height that fits every person. Your leg length, desk height, shoes, and chair all affect the setting, so use your posture as the guide.

How high should your office chair be for your body?

Your seat is at a useful height when your feet are supported and your knees are near hip level. Aim for thighs that are close to level, without pressure building at the front edge of the seat.

Sit back in the chair and place both feet flat on the floor. If your heels lift or your toes take your weight, lower the seat if you can.

Check that your knees aren't much higher than your hips. A slight difference is fine; focus on whether you can sit comfortably without sliding forward or leaning to reach the desk.

A chair that fits one person's body may not fit another's. For more guidance by height, see our pages on office chairs for short people and office chairs for tall people.

How do you set office chair height step by step?

Adjust the chair while seated, then check your feet, knees, and reach. Make small changes and give yourself a moment in each position before deciding whether it feels right.

1. Sit with your back against the backrest and your hips toward the rear of the seat.
2. Keep your feet flat on the floor and your shoulders relaxed.
3. Raise or lower the chair until your knees are near hip height and your thighs are close to level.
4. Reach toward the desk without lifting your shoulders or stretching forward.
5. Recheck your feet and knees after settling into the seat.

Use the chair's height control as intended. If the chair won't stay at the height you set, follow our guide to an office chair that won't stay up.

What if your desk makes the chair too high?

Keep the chair high enough to reach the desk comfortably, then support your feet. A footrest can help when lowering the seat would leave your arms too low for the work surface.

The HUANUO footrest has 3 height settings and a platform that tilts from side to side. Its textured surface gives your feet a place to rest while you work.

Check that the footrest fits beneath your desk and lets you place both feet on it. Skip it if your feet already rest flat and the platform would crowd your leg space.

The Mind Reader footrest adjusts from 3.25 to 6.25 in high. Its textured, tilting platform is another option if you want to change the height and angle under your desk.

Choose based on the space under your desk and the height your feet need. A footrest won't correct a seat that is too deep or a desk that forces you to reach with raised shoulders.

How can you tell if your office chair is too low?

Your chair may be too low if your knees sit well above your hips or you have to reach upward to use the desk. Raise the seat a little and check whether your feet stay supported.

Keep your back against the chair while adjusting. If you slide forward to reach the desk, the issue could involve desk height or seat depth as well as chair height.

After changing the seat, make sure your feet still rest on the floor. If they don't, use a footrest or try a different desk and chair setup.

What should you check besides seat height?

Seat height is only one part of a comfortable fit. The seat depth, back support, and desk position also affect how you sit.

With your back against the backrest, check that the seat doesn't press into the backs of your knees. You should be able to sit back without the seat edge blocking your legs.

The Nexthro Ergonomic Chair with Lumbar has a seat listed as 20.9 in wide by 20.7 in deep and adjustable lumbar support. Its height-adjustable frame may suit readers comparing chair fit, but those seat dimensions may not suit every body.

Consider both seat depth and height before choosing a chair. Our guide to making an office chair more comfortable covers other fit adjustments.

Can a chair designed for short users help with seat height?

A chair designed for shorter users may be worth considering if a standard seat feels too high or deep. Check the seat and adjustment details against your own measurements before choosing.

The Nexthro Leather Chair for Short Users has a padded backrest, a separate lumbar pillow, and flip-up armrests. Its product title identifies it for short people, but the chair's listed dimensions alone don't say which seat height will fit you.

If you're still comparing sizes, use our office chair fit guide for short people to think through seat height and depth together. A label alone can't replace checking how the chair fits your legs and desk.

How often should you change your chair height?

Recheck your chair height whenever your desk setup or footwear changes. A new desk, different shoes, or a change in how you work can affect where your feet and knees sit.

If several people share the chair, adjust it for each person before sitting down to work. Don't assume the last person's setting will support your feet.

How high should your office chair be? Use this fit check

For proper office chair height, set the seat so your feet are supported, your knees are near hip height, and your thighs are close to level. If your desk requires a higher seat, add a stable footrest and check that your legs still have room underneath.

Choose an adjustable chair if you need to change the seat position for your body. If the chair fits but your feet don't reach, choose a footrest that suits your desk space; if the seat itself feels too large, compare chairs for shorter users.

Frequently asked questions

How high should an office chair be from the floor?

There isn't one correct floor-to-seat measurement for everyone. Set the chair so your feet rest flat, your knees are near hip height, and your thighs are close to level; adjust from there if the desk, shoes, or your body proportions change the fit.

Should my feet touch the floor in an office chair?

Your feet should rest on the floor or on a stable footrest when you're seated at your desk. If raising the chair to reach the desk leaves your feet unsupported, add a footrest rather than balancing on your toes.

Is it better for an office chair to be high or low?

Neither setting is best by itself; the chair should fit your body and workstation. Start with supported feet and knees near hip height, then check that your shoulders stay relaxed and your forearms can reach the desk without lifting them.

What if my office chair is too high?

Lower the seat until your feet rest flat and your thighs feel supported, as long as you can still reach the desk comfortably. If the desk only works with a higher seat, keep the chair at that height and use a footrest to support your feet.
