Choosing an office chair based on your height seems logical. However, knowing that you are 5'4", 5'10" or 6'2" is not enough to determine which chair will suit you.
Two people of the same height can have very different proportions: long legs and a short torso, shorter legs and a longer back, narrower or wider hips. Their needs will therefore not necessarily be the same.
To choose the right office chair dimensions, it is better to measure your body rather than rely solely on your height. Four measurements are particularly useful: hip width, thigh length, the height from the floor to the underside of your thighs, and the distance between your elbows.
Here is how to take these measurements and, most importantly, how to use them to choose a chair that suits your body type.
The Right Chair Size Depends on Your Body Type, Not Just Your Height
Your height remains useful information. It can quickly indicate whether a person falls at one end or the other of the dimensions typically offered by a chair.
But it is only a starting point.
Let’s take two people who are both 5'8". The first has long legs and a relatively short torso. The second has shorter legs and a longer torso.
The first person may need a deeper seat and a different height range. The second may be perfectly comfortable with the same seat width, but find it too deep.
This is why, at Solutions M3, when we advise a client remotely, we may ask for certain body measurements rather than relying solely on their height.
It is also important to distinguish between dimensions and comfort.
A chair can have dimensions that are compatible with your body type without necessarily being your preferred chair. Some people like a firm seat, while others prefer a softer feel. Some appreciate very noticeable lumbar support, while others prefer more subtle support.
The first step is therefore to find a chair that can adjust properly to your body. Comfort preferences can then help narrow down the compatible models.
However, dimensions are only one of the criteria to consider when choosing the right office chair.
The 4 Measurements to Take Before Choosing Your Office Chair
Grab a measuring tape.
Sit with your back well supported, your feet flat on the floor and your legs approximately at 90°. Also position your forearms at approximately 90°, with your elbows close to your body.
You can now take four measurements.
1. Measure Your Hip Width
Measure the widest part of your hips while you are seated.
This measurement helps determine the seat width you need.
However, the goal is not to choose the widest possible seat.
A seat that is too narrow can make you feel confined. Conversely, an unnecessarily wide seat can place the armrests too far apart and force you to move your arms away from your body to use them.
At Solutions M3, we therefore look at hip width together with the distance between your elbows.
For example, a person whose hips measure approximately 18 or 19 inches could very well fit a regular seat. The measurement between their elbows will then help us determine which armrests and adjustment options are appropriate.
2. Measure Your Thigh Length
Measure from the back of your buttocks to the crease behind your knee.
This measurement helps determine the seat depth you need.
When you are properly positioned, your back should be able to remain supported by the backrest without the front of the seat putting pressure behind your knees.
At Solutions M3, we generally look for approximately one to three fingers of space between the front edge of the seat and the crease behind the knee.
A seat that is too deep can therefore be a problem even if the chair height is perfect. Conversely, someone with longer thighs may find a seat too short to properly support their legs.
Adjustable seat depth becomes particularly useful when a chair needs to accommodate different body proportions.
3. Measure From the Floor to the Underside of Your Thigh
This third measurement helps determine the seat and cylinder height range to look for.
One detail is important: take this measurement under the same conditions in which you work.
If you work in a professional office and normally wear shoes, take the measurement with your shoes on.
If you work from home and usually work without shoes, measure yourself without shoes.
This difference can be important when a person is close to the minimum or maximum height allowed by a chair’s cylinder.
4. Measure the Distance Between Your Elbows
Place your arms close to your body and your forearms at approximately 90°. Then measure the distance between your two elbows.
This measurement helps determine the appropriate armrest spacing.
Armrests that are too far apart force you to move your arms outward to find support. If they are too close together, they can feel restrictive.
When properly positioned, armrests should support your forearms while keeping your elbows close to your body and your shoulders relaxed.
How Do You Convert Your Measurements Into Chair Dimensions?
Once you have taken your four measurements, a chair’s technical specifications become much easier to interpret.
| Your Measurement | What to Check on the Chair |
| Hip width | Seat width |
| Buttocks to the crease behind the knee | Seat depth |
| Floor to the underside of the thigh | Seat and cylinder height range |
| Distance between the elbows | Armrest spacing and adjustment options |
| Torso and back proportions | Backrest height and lumbar support position |
The important point is that none of these dimensions should be evaluated completely on its own.
A chair may have the right seat width but armrests that are too far apart. It may offer the right depth but not lower enough. A backrest may fit one person perfectly while positioning the lumbar support in the wrong place for someone else.
This is also why two chairs described as having “standard” dimensions can provide a very different experience.
How Do You Know If Your Chair Is Too Big or Too Small?
Signs That a Chair Is Too Big
A chair may be too big if:
- the seat is so deep that you cannot keep your back properly supported without feeling the edge of the seat near
- the crease behind your knees;
- the chair does not lower enough for your feet to rest properly on the floor;
- the armrests are so far apart that you have to move your arms outward to reach them;
- the lumbar support does not reach the right spot on your back.
In these situations, adding more adjustment options does not necessarily solve the problem. The chair’s basic dimensions must first be compatible with your body.
Signs That a Chair Is Too Small
For a taller person, the opposite problem can occur.
The seat may be too short to properly support the thighs. The backrest may not extend high enough. The armrests may remain too low even when adjusted to their maximum height, or the cylinder may not allow you to reach the desired height.
A wider person may also feel compressed around the hips or between the armrests.
Shorter, Taller and Larger-Bodied People: Different Needs
These terms are sometimes used as if they simply referred to different sizes of the same chair. In practice, the criteria to check are not exactly the same.
For a Shorter Person
A shorter person should pay particular attention to the minimum seat height and seat depth.
A chair that does not lower enough can prevent your feet from resting properly on the floor. A seat that is too deep can reach the back of your knees before your back is properly supported.
The position of the armrests is also important: they need to be able to move close enough to your body.
Some models of office chairs for shorter people specifically offer dimensions and adjustment ranges that are better suited to these needs.
For a Taller Person
For a taller person, we pay particular attention to seat depth, backrest height, the cylinder height range and armrest adjustments.
A standard chair may be wide enough, but offer a seat that is too short or a backrest that does not correspond to the proportions of the upper body.
Office chairs for taller people allow you to look for models offering dimensions that are better suited to these proportions.
For a Larger-Bodied Person
A chair for a larger-bodied person raises additional questions.
In particular, you need to check the usable seat width, the space available between the armrests, the seat depth and the chair’s weight capacity.
Office chairs for larger-bodied people allow you to compare models that are better suited to these needs.
A taller person is therefore not necessarily a larger-bodied person, and vice versa.
Don’t Forget the Height of Your Desk
It is possible to choose a chair whose dimensions fit your body very well and still encounter an ergonomic issue.
Why? Because the chair is only one part of the workstation.
Suppose your fixed desk is relatively high. To position your arms correctly in relation to the keyboard, you need to raise your chair. But once the chair is raised, your feet no longer rest properly on the floor.
The chair is not necessarily incorrectly sized.
A footrest can then help recreate stable support under your feet while maintaining the necessary height in relation to the desk.
The height of your work desk must therefore also be taken into consideration.
This is why it is preferable to consider the person, the chair and the workstation as a whole.
The Right Dimensions Alone Do Not Guarantee Comfort
Here is something a dimension chart cannot predict: your preferences.
In our showroom, we can seat two people with similar body types in the same chair and get two completely different reactions.
One may prefer a firmer seat. The other may prefer more flexibility. One person may like to feel strong lumbar support, while another may prefer something more subtle.
Body type itself also comes with nuances. Two people of the same height can have different leg lengths, a longer or shorter back, or a more or less pronounced lumbar curve.
Dimensions therefore serve first to identify chairs that can adapt well to your body. Comfort preferences can then help you choose among the compatible models.
More Adjustments and a Higher Price Do Not Automatically Mean a Better Chair for You
Some chairs offer a huge range of configuration options. Others are simpler and more affordable.
At Solutions M3, our goal is to offer the model that best fits the need and the budget, rather than automatically choosing the most expensive model.
Take the Cierra and airCentric families, for example. Depending on the configuration you are looking for, an airCentric may offer features that a user will appreciate or that their body type requires. If their budget is better suited to a Cierra, the right approach is to determine which adjustments are truly essential and which compromises are acceptable.
The YouToo is another example. Its synchronized mechanism differs from a multifunction mechanism, but it still offers several ergonomic adjustment options, and its design is particularly appreciated for working from home.
The number of adjustments is therefore not an end in itself.
An adjustment is useful when it allows the chair to better adapt to its user.
Can You Choose the Right Office Chair Dimensions Online?
Yes. The problem is not buying a chair online. The problem is choosing one without having the right information.
Before ordering, check the following:
- your body measurements;
- the actual seat width and depth;
- the height adjustment range;
- whether the seat depth is fixed or adjustable;
- the armrest adjustment options;
- the backrest height and adjustments;
- the chair’s weight capacity when this is a consideration;
- the height of your workstation.
At Solutions M3, all online orders are processed by someone with experience in office furniture. When a configuration seems unusual to us or an element raises a question, we can contact the customer to validate certain choices before proceeding with their order.
It is not always possible to detect a problem from an order, but this verification adds a human dimension to the online shopping experience.
So, What Office Chair Size Should You Choose?
Don’t start by simply looking for a chair “for someone who is 5'6"” or “for someone who is 6'.”
Start with your body.
Measure your hips, your thighs, the height from the floor to the underside of your thighs, and the distance between your elbows. Then compare these measurements with the seat width and depth, the height range and the armrest adjustment options.
Also check the backrest, lumbar support and the relationship between the chair and your desk.
Your height remains useful, but your proportions allow you to understand much more precisely what you actually need.
And if several models match your measurements, your comfort preferences, how you use the chair and your budget will help you make the final choice.

FAQ
What Office Chair Height Should I Choose Based on My Height?
Your height provides a starting point, but it is not precise enough on its own. Instead, measure the distance between the floor and the underside of your thigh while seated to determine the height range you need. Take this measurement with or without shoes depending on your usual working conditions.
What Seat Depth Should I Choose?
Measure the distance between the back of your buttock and the back of your knee. When seated with your back against the backrest, we at Solutions M3 generally aim for about one to three fingers’ width of space between the edge of the seat and the back of your knee.
Is a Wider Chair More Comfortable?
Not necessarily. The seat should provide enough space for your hips without being unnecessarily wide. You also need to consider the position of the armrests: if they are too far apart, you may have to move your arms outward to use them.
What Should I Do If My Feet Don’t Touch the Floor?
First, check whether the chair can be lowered enough. If you nevertheless need to keep it higher to work properly at a fixed-height desk, a footrest can provide the necessary support.
Does a Tall Person Necessarily Need a Larger-Bodied Chair?
No. Being tall and being larger-bodied do not correspond to the same needs. A taller person may primarily need a deeper seat, a higher backrest or a greater height range. A larger-bodied person may need a wider seat, more space between the armrests and an appropriate weight capacity.
