What is Good Seat Depth For Short Person? [Dimensions Guide]

The purpose of all office chairs is to provide comfortability and ergonomic support. But short people sometimes find a difficult to adjust the chair to match their needs, resulting in an uncomfortable sitting position.

No doubt, there are a few office chairs on the market that are designed for people of all heights, but a short person may still face some challenges when it comes to finding the perfect chair.

Many standard office chairs are designed for people who are five feet tall or more, which can leave a shorter person feeling like they are sinking into the chair.

Additionally, a short person may have difficulty reaching the keyboard and mouse, which can lead to discomfort and strain. Another issue is that the back of a short person’s head may not make contact with the back of the chair, resulting in poor posture and neck pain.

Moreover, a shorter person may have trouble reaching the floor with their feet, and also struggle to find a position that is both comfortable and ergonomic leading to discomfort in so many ways.

For a short person, seat depth is more important than seat height actually.

A good starting point for seat depth is 16-18 inches for a short person. The average person is about five feet, nine inches tall, so a good seat depth for a short person would be about 17 to 18 inches. This is because the average person’s legs are about 24 inches long, so they need a seat that is about six inches longer than their legs in order to be comfortable.

In this solution blog article, we walkthrough complete decision-making guidelines on the right size office chair for a short person.

Let’s get started.

When is a Person Considered to be Short and Petite?

A person is typically considered to be short and petite if they are under 5’4″ for women and under 5’8” for men and has a small frame. However, there is some flexibility in these parameters, as people of all heights and body types can be considered short and petite depending on the specific context.

For example, a person who is 5’6″ but has a very slim build might be considered short and petite in the fashion world, while someone who is 5’2″ but has a more athletic build might not. Ultimately, it is up to the individual to decide whether or not they consider themselves to be short and petite.

Key Specifications for Right Size Office Chair For Short Person

While there are a variety of problems that a short person may face on an office chair, there are also a number of solutions. For example, many office chairs now come with a variety of settings to accommodate different body sizes.

This helps to improve comfort and ease up the strain. By taking these measures, a short person can maintain proper posture and comfort while working at a desk.

Good Seat Depth for a Short Person: Around 18 Inches, Minimum

Office chair seat depth is the distance from the back of the chair to the front of the seat. Short office chairs typically have a seat depth of 17 to 18 inches.

A seat that is too shallow can cause your legs to dangle uncomfortably, while a seat that is too deep can make it difficult to get in and out of the chair. Therefore, it is important to choose an office chair with a seat depth that is appropriate for your height and build.

To measure the seat depth of a short office chair, first sit in the chair and slide your bottom all the way back until your back is against the backrest.

Next, measure from the front edge of the seat to the back of your knees. Finally, add 2 to 3 inches to account for legroom. This will give you the seat depth of the chair.

This measurement is important because it helps to determine how much space you will need for your legs when sitting in the chair.

Additionally, you may want to consider looking for a chair with an adjustable seat depth, as this will allow you to customize the fit to your own body size.

Good Seat Height For Short People: Around 18 Inches, Minimum

The seat height of an office chair is important for many reasons. A good seat height allows the user to sit with their feet flat on the floor, which helps to improve circulation and reduce fatigue. It also enables the user to maintain a good posture, with their back in a neutral position and their shoulders relaxed.

For most people, a seat height of 17-20 inches is ideal. However, if you are shorter than average, you may need to adjust the seat height down to 15-16 inches. This will help to ensure that your feet remain flat on the floor and that you are able to maintain good posture. The good thing is seat height is not so important as seat depth.

To calculate the seat height of an office chair for a short person, start by measuring the distance from the floor to the individual’s knee. Next, subtract 2 inches from this measurement. This will give you the seat height that you should look for in an office chair. Keep in mind that the seat height of an office chair is not the only factor to consider when choosing a chair.

Armrest Height: Around 2-3 inches High

For a short person, this means that the armrests are closer together than they are for a taller individual. However, it is important to make sure that the arms are not constricted in order to maintain a full range of motion.

As a general rule, the armrests should be about 2-3 inches higher than the seat cushion.

The ideal armrest height for a short person is one that allows the elbows to be comfortably flexed at a 90-degree angle. This will allow the shoulders to be relaxed and prevent the arms from becoming fatigued. The armrests should also be positioned close to the body so that the forearms are supported.

Also, the armrests should also be high enough so that the person’s hands are in line with their thighs. If the armrests are too low, it can cause discomfort in the shoulders and neck. Conversely, if the armrests are too high, it can make it difficult to get in and out of the seat.

Backrest Height and Tilt

For a short person, the ideal backrest height is 14 to 16 inches. The ideal tilt of the office chair is 100 to 110 degrees. The backrest should be at a 90-degree angle to the seat. The seat should be parallel to the floor. The knees should be at a 90-degree angle to the hips. The feet should be flat on the floor.

Because they are smaller in stature, short people often need a chair with a higher backrest and a more pronounced tilt. This helps to provide support for the lower back and prevents the person from slouching. In addition, a shorter person may need to adjust the height of their seat in order to be able to reach the keyboard and mouse. 

Lumbar Support

For shorter people, it is often necessary to choose a chair with more pronounced lumbar support in order to ensure proper alignment.

As we said earlier, most chairs are designed for people of average height, which means that they don’t provide the necessary support for short people. This can lead to back pain and other health problems. One way to solve this problem is to choose a chair with lumbar support.

The lumbar region of the spine is responsible for bearing most of the body’s weight, so proper support is essential for maintaining good posture and preventing pain. Most office chairs have some form of adjustable lumbar support, which allows the user to customize the amount of support according to their own needs.

Additionally, many chairs offer features such as height-adjustable seats and tilt mechanisms that can further customize the fit and provide additional support for the lower back.

How can I make my chair more comfortable for my short person?

Short people often have trouble finding an office chair that is comfortable for them. The first thing you can do to make the office chair comfortable for a short person is by removing padding if a chair has a thick cushion or adding a cushion to a less padded chair.

This will help the short person to be able to sit all the way back in the chair without their legs being elevated too high off the ground.

Another thing that can be done to make an office chair more comfortable for a short person is to adjust the backrest so that it provides more support for the lower back. This will help to prevent the short person from slouching forward in their chair, which can cause pain in the lower back and legs.

Finally, make sure that the armrests on the office chair are adjustable so that the short person can rest their arms at a comfortable level. By making these simple adjustments, you can make an office chair much more comfortable for a shorter individual.
