The Ultimate Gaming Chair Sizing Guide

The point of a gaming chair is to support your back while providing consistent comfort. These days, gaming chairs come in small, medium, and large sizes. This gaming chair size guide explains why a proper size yields the best benefits. It also points out what dimensions to consider before buying a chair.

Wide sizes need to make sure to buy a wide chair they can fit into.

Extra-wide sizes should look for seat dimensions wide enough to cradle their hips. Average sizes with slim hips have the widest range of options. They can squeeze into small chairs, make do with XL chairs, or enjoy an ideal fit with a medium-sized model.

Choosing the right size ergonomic chair
A small body in a large gaming chair will lose the back support benefits that gaming chairs provide.

Smaller users who buy large chairs will regret it. A backrest that doesn’t fit the body won’t provide effective back support. The support pillows won’t meet the curves of the spine. If the floor to seat range is too high, the feet will dangle, instead of planting on the floor.

To get a sense of the right size for your needs, there are a few factors to consider. Start by considering some chair sizing essentials.

Chair sizing essentials

Gaming chair sizing numbers are useless — unless you understand them. Here are the most important things to consider before looking at the numbers:

International sizing

Most gaming chairs are made in Asia and sold in America. But average sizes in Asia are much smaller than they are in the west. Check out these average body sizes by country:

 Average size of menAverage size of women
USA5'8" 200 pounds5'3" 171 pounds
China5'6" 155 pounds5'2" 130 pounds
United Kingdom5'8" 191 pounds5'4" 160 pounds
South Korea5'7" 163 pounds5'3" 133 pounds

Broadly, cheaper gaming chairs tend to fit Asian average sizes. Some expensive gaming chairs are larger, thus a better fit for average western sizes.

Wide vs narrow seats

PC gaming chairs have two types of seat designs. The most common type has curved edges. These restrict the legs and create a snug fit, like sitting in a race car cockpit. This provides crisp ergonomics that keep your spine in perfect alignment.

The second type is a flat seat with no edges. The advantage of the flat seat design is more legroom. That makes them more comfortable, but easier to sit using sloppy posture. Check out a selection of specialty chairs with flat, wide seats:

Important gaming chair dimensions

Gaming chairs come with a tall backrest. Between the backrest and your body are neck and back pillows. As you lean your into the backrest, the pillows set your spine into perfect alignment.

Gaming chair back support
Gaming chairs keep your spine in healthy alignment.

Having a backrest height that fits your body ensures you’ll be able to place your neck pillow correctly. Most backrests range between 33″ and 30″ high. Anything lower or taller is for extremely tall or short sizes.

Choosing the right sized gaming chair
Choosing the right sized chair will ensure optimal ergonomic support.

When checking chair dimensions, look for these essentials:

  1. Seat width and depth: make sure there’s enough room to comfortably cradle your hips.
  2. Backrest width and height: the height should match your body. The width should give you enough space to avoid hunching your shoulders.
  3. Floor to seat range: ensure a height that lets you plant your feet firmly on the ground. Also, check that that maximum seat height matches your desk.
  4. Size rating: most gaming chairs come with a recommended size rating, along with a maximum weight capacity.

Gaming Chair Sizing Guide

To realize the ergonomic potential of gaming chairs, it’s important to pick the right size. The guide pertains to all gaming chair brands covered on this website.

Gaming Chairs for average sizes

We define average-sized users as those between 5’6″ to 5’10” tall weighing less than 200 pounds. These users can squeeze into small chairs or fit decently into extra-large chairs. Most gaming chair brands don’t clarify whether their chairs are for small, medium, or large sizes. That’s why it’s important to check the specs of a chair before buying.

Gaming Chairs for extra-large sizes

Big and tall heavyweights tend to have more pronounced posture problems than average sizes. During both rest and activity, the spine manages weight distribution.
