A dimension-conscious approach yields the best match when it comes to deciding which ergonomic office chair is best for you. When considering office chair measurements, there are a few key points to consider. The first consideration is the exact size of the chair, followed by the dimensions of the person who would be the one using the chair. Of course, you also need to consider office desk size. Read on to know more about office chair dimensions.

Basic Dimensions of an Office Chair

There are tons of options to choose from when it comes to office chairs based on different office chair dimensions. However, not every chair can work for everyone. It is vital to find a chair that is specific to your needs and that will fit your height as everyone has a different body type. Size is one of the most important desk chair dimensions. There are three main sizes of office chairs these are:

  • Petite office chairs: These office chairs are smaller than the standard size as this chair accommodates users who have a smaller stature. Petite office chairs are narrower, they have a shorter back and the seat pan is shallower to accommodate those with a smaller stature.

  • Standard office chairs: These chairs work for most people as they are built for an average size adult that has a general weight of 250 pounds. In terms of 

    desk chair height standards, office chairs are made for people who are between 5 to 6 feet. Ergonomic adjustments are however available.
  • Big office chairs: These office chairs are typically designed for individuals who have a larger stature and height. Big office chairs are suitable for people taller than 6 feet. These chairs also feature different weight capacities from up to 500 pounds.


Chairs do not have any particular standard office chair dimensions, however, most of them fall within the following office chair measurements: 

  • Height of chair: 16 to 20 inches

  • Width of a chair: 19 to 21 inches

  • Depth of chair: 15 to 19 inches 

The overall size of an average office chair varies based on the height of the backrest and whether or not the office chair has a neck rest; an office chair may range between 31 to 40 inches depending on the size of the chair from the floor to the top of the office chair.

Importance of Having a Comfortable Office Chair

On average a substantial proportion of the population spends up to 5 to 8 hours each day sitting at their desk. Whether you sit by your desk for a short period of time or more than 8 hours, a mildly unpleasant chair without proper office chair dimensions might cause a painful workplace injury due to the time spent using an office chair. Muscular and skeletal disorders are common in individuals who spend a lot of time sitting. 

The Federal Occupational Safety and Health Administration or OSHA states up to two million people suffer from musculoskeletal problems due to copious hours of sitting at their desk.

For this very reason, it is suggested that you choose an ergonomic office chair. 

Although employees spend a lot of time seated at desks, individuals do not always have the finest office chair to sit on. Sitting for long periods of time on chairs that do not give enough support and are not properly set up can result in more than simply lower back discomfort. There are many health implications by sitting on an uncomfortable chair that offers no back support:

  • Fatigue

  • Increased levels of drowsiness

  • Problems with concentration

  • Constant headaches

  • Prone to obesity

  • Can negatively affect your hearts health

Ergonomic Office Chairs

Ergonomic chairs are particularly developed to help the human body. To do so, they share certain features as well as dimensions of desk chair with all chairs of this sort. In comparison to a standard chair, these features make a significant difference in providing back support and assisting in the relief of back discomfort. Ergonomic office chairs have multiple features and desk chair dimensions:

  • The first characteristic is seat height: A

    good ergonomic chair should have an adjustable seat height. Humans vary in size, and the optimal sitting position is one where your feet can be placed flat on the floor.
  • Following these office chair dimensions are seat width and depth: A good chair should have a depth that allows for a space between two and four inches between the edge of the chair and the back of your knees.

  • Next, we have a seat tilt: The best ergonomic chairs allow for the seat to tilt. This allows for the correct pelvis placement, which in turn helps with 

    ergonomic chair posture. People who sit for extended periods tend to suffer from anterior pelvic tilt, and the tilt of an ergonomic chair can help combat this.
  • The fourth computer chair dimension is backrest lumbar support. This refers to adjustable back support, which supports the natural "S" shape of the spine. This prevents slouching and relieves pressure from both the spine and pelvis. All

    ergonomic chairs for back pain have this incorporated into the design.
  • The fifth feature is the ability to recline the backrest: This function enables the individual to utilize the chair flexibly. This allows the chair to give additional spinal support while relieving pressure on the upper body and back muscles.

  • The next office chair dimension is a swivel:  This feature enables greater mobility. This allows the person using the chair to reach different locations without having to strain oneself unnecessarily.

  • Armrests are always present in good ergonomic seats: Armrests take the tension off your shoulders, enabling them to relax. When typing, avoid utilizing the armrests since this might cause pressure on the wrists and forearms.

  • Another crucial element of an ergonomic chair is a headrest: This feature supports the upper neck and the rear of the head. The addition of a headrest will also decrease tension in the upper chest and shoulders.

    ergonomic chair wheels: The wheels allow you to move around comfortably without hurting your back. The wheels of your chair should be selected based on the type of flooring you have. Hard flooring needs softer wheels, whereas carpet necessitates stronger wheels.

Office chairs that are leather give a feeling of luxury and comfort right away. While comfortable, not all leather work chairs are designed to be worn for extended periods.

Between mesh vs leather office chair, leather ones are often fairly costly, although there are less expensive leather options available. 

Leather chairs must preferably be utilized in colder areas. When exposed to high temperatures, leather can get sticky and cause the user to sweat more than usual. A leather office chair could be the route to go if you want to make a public statement and work in a great setting.

Office Chairs made from Mesh

Office chairs that are mesh are an excellent solution for offices located in warmer countries or in generally overheated offices. The mesh material's breathable perforations allow for flowing air to keep you fresh throughout the day. 

Mesh chairs are often fairly light. So, if you need to move your chair several times during the day, a mesh office chair might help.

Task Office Chairs

Task office chairs are by far the most basic form of an office chair. They are also the most affordable. It provides many chair width and sizes. These chairs provide the fundamental function of providing a seat, and other features like adjustable back support and headrests are sometimes overlooked throughout the design process. 

If you don't need an office chair for certain work and just need a place to sit for a couple of hours, a task chair might be a great decision. However, if you sit for long amounts of time throughout the day, a more substantial office chair may be required.

Kneeling Office Chairs

As you may be aware, sitting for long periods every day is not the best thing one can do. This is because muscles aren't built to sit for long amounts of time on a daily basis. Nevertheless, for many contemporary employees, this is virtually difficult to avoid. For individuals who are worried about back discomfort, or if you already suffer from back problems, a kneeling office chair might be a great solution to alleviate the strain on your muscles in your body. It has many suitable office chair dimensions for knee-strain users.

A kneeling office chair forces you to reconsider your alignment and even encourages you to sit more mindfully. The primary function of a kneeling office chair is to distribute your body weight across your legs and glutes, therefore reducing strain on the lower back.

Heavy-duty office chairs are unquestionably the biggest and perhaps the most durable sort of chair available. They offer a special function in that they appeal to the bigger consumers who require it the most. It may have the biggest office chair width and size as well as office chair measurements compared to other types.

Staying seated for long amounts of time on an office chair with no adequate neck and shoulder support may be quite painful, so choose a chair that fits the particular body type you have.

Standard Chair Dimensions for Small People

Most brands offer "petite" chairs in contrast to the "big and tall" chairs made for plus-size people. Typically, these chairs will have dimensions of 28.35” D x 23.82" W x 14.96" H. Please note that these are general measurements. The actual office chair dimensions can vary from one product to another. However, we recommend you look for office chairs with similar chair dimensions whenever you're shopping for a new chair.

While most office chair measurements are useful for the average person, some people are below the average height, and regular office chairs can be too tall for them. It can be complicated to find a comfortable office chair, but having in mind the correct dimensions can help you find the best option for you. Many of these seats also include back support for the office chair to help you correct your posture.

Standard Desk Chair Dimensions for Big Guys

The desk chair dimensions can vary from one1 manufacturer to another, but we recommend you look for similar measurements. Typically, these chairs have an improved weight capacity that goes from 300 lbs up to 500lbs.

You can find lumbar support office chairs for big guys as well. There are gaming chairs with these measurements and even mesh options. Hence, it’s all a matter of exploring different options until you find an option that resonates with your preferences and needs.

Proper Posture Sitting in an Office Chair

Once you've got a chair with the appropriate chair dimensions and chair width for your height, the next step is to start practicing good sitting habits that can help you distribute your weight evenly throughout your body, reducing your physical complaints in the process.

Setting up your workstation

The ergonomic posture doesn't only depend on your chair but also on the placement of the rest of your office equipment and peripherals. Here we describe what you need to do to start setting up your workstation ergonomically.

  • First, make sure that your computer screen is at least one arm’s length away from your eyes.

  • Next up, set up your keyboard and monitor so you can reach them easily. Preferably, try to place one besides the other.

We recommend using ergonomic peripherals to make sure that your hands are appropriately supported throughout the day. You can find split keyboards, keyboard wrist rests, and even ergonomic wrist rests for your mouse that follows your movements naturally. This way, the impact of repetitive motion will not harm you negatively.

Practicing the correct sitting posture

Many types of posture exist, but the correct typing posture will allow you to sit comfortably in your office chair while you’re working. Of course, remaining in the same position for prolonged periods is never recommended, but these are general guidelines that we recommend following so you can prevent physical complaints once you’ve finished working.

  • First, adjust the height of your office chair so you can place your feet on the floor without help. You can also help yourself with a footrest if you’d like to be more comfortable.

  • Your knees and your hips should be at the same level.

  • Place your hands on the keyboard. Keep your hands at or below elbows level.

This is the proper desk posture you should have at an office desk. However, as we've mentioned previously, it's not recommendable to remain in the same position as it increases the risk of pain and discomfort in certain areas. We recommend you take breaks now and then to prevent such situations from happening. Plus, doing so can also help you clear your mind and improve your focus.


What should I look for when buying a new office chair?

Diverse aspects to take into account while looking for a new ergonomic chair exist. We recommend you take into account the following elements: adjustability, recline and lumbar support.

  • Adjustability

    – You should be able to easily adjust your chair's important features, such as seat height and armrest height.
  • Recline

    – The recline feature is very important in office chairs, as it allows you to sit back and take breaks from time to time whenever you need it. Some chairs come with lockable positions, while others allow you to modify them as you prefer.
  • Lumbar support

    – The chair you'll use for work should be equipped with appropriate lumbar support that keeps your lower back area comfortable. This part of the chair is also meant to correct your posture.

There are many other factors you should take a look at, such as the swivel, footrest and headrest. However, the features previously mentioned are the most essential in a chair as they will allow you to sit comfortably during your work sessions.

How do I measure myself for an office chair?

If you'd like to find out whether an office chair is appropriate for you or not, we recommend you try out the chair and modify the height. Try finding a height that allows you to sit in the ergonomic posture, with both feet on the floor and straight legs. If you can't reach the desk properly or any other problem occurs, perhaps you and that chair are not a good match.

Where should lumbar support be placed on a chair?

The lumbar support in a chair should be placed in the lower area of the backrest. Typically, the backrest has a "curve" that lets you know the lumbar support. If not, it will have a cushion or some other indicator, so you know where it is located. However, some chairs allow you to adjust it, or you can even purchase an external lumbar support pillow to provide yourself with even more comfort.

How do you adjust the angle of an office chair?

It depends on the chair model. Some chairs include a level that allows you to modify the recline angle, while others have a mechanism below the seat that allows you to “release” the tension of the chair and make it more reclinable.

The Bottom Line

Selecting an ideal office chair may appear to be a straightforward process, but when you think about it, many considerations come into the equation and may have a significant impact on your selection. Selecting a decent office chair entails more than simply selecting one that will look great next to your desk. It all comes down to getting a chair with a decent design and good features.
