Choosing the right office chair is not only a matter of design and comfort but also of paying attention to its size. The ideal chair size is critical to supporting posture, reducing the risk of injury, and increasing productivity.
This article will discuss the importance of appropriate office chair size, ideal dimensions, and factors to consider when choosing an office chair based on height and ergonomic needs.
The Importance of the Right Office Chair Size
An office chair not the right size can cause various health problems, such as back pain, stiff neck, and poor blood circulation. If the chair is too small or too big, your sitting posture will become unbalanced, causing discomfort when working for a long time. Therefore, choosing an office chair sized according to your body shape and needs is essential.
Ideal Office Chair Size Based on Body Height
The size of the office chair must be adjusted to the user's height so that the sitting posture is ergonomic. Here are some office chair size guides based on height:
1. Body height 150-160 cm
For people with a height of around 150-160 cm, the ideal office chair size has a seat height between 40-45 cm from the floor. This size ensures the user can comfortably place their feet on the floor, and the knee angle is approximately 90 degrees.
2. Body height 160-170 cm
If your height is between 160 and 170 cm, the recommended office chair size has a seat height of around 43-48 cm. With this size, users can sit with good posture, keep their back straight, and form an ergonomic angle with their knees.
3. Body height: 170-180 cm
For people with a 170-180 cm height, the ideal office chair has a seat height of 45-50 cm. A chair of this size allows users to sit comfortably without feeling too low or too high so that body posture is maintained.
4. Body Height Above 180 cm
For users with a height of more than 180 cm, a chair with a seat height of around 48-53 cm is ideal. This higher chair allows users to sit comfortably and ensures that body posture remains ergonomic, especially at the knees and lower back.

Standard Office Chair Dimensions
Apart from seat height, several other dimensions must be considered when choosing an office chair, such as seat width, depth, and backrest height. The following are standard sizes that can be used as a reference:
1. Chair Seat Width
The ideal seat width for an office chair is usually 45-55 cm. This size provides enough space for users to sit comfortably without feeling cramped. For users with larger bodies, choosing a chair with a wider seat width will provide more comfort.
2. Seat Seat Depth
The seat depth of the chair is also essential to ensure that the lower back gets good support. The ideal depth ranges from 40 to 50 cm. If the seat is too deep, the user may have difficulty getting proper back support, and if it is too shallow, the user may find it uncomfortable.
3. Backrest Height
The backrest of an ideal office chair is around 45–60 cm high, depending on the user's height. A high backrest provides better support for the upper back and neck, especially if equipped with a headrest.
Factors to Consider in Choosing Office Chair Sizes
Choosing an office chair is a matter of size and considering several other ergonomic factors affecting comfort and health. Here are some factors to pay attention to:
Height Adjustment
A good office chair should have a mechanism for adjusting the seat height. This feature is essential to change the chair to the user's height, ensuring an ergonomic sitting posture. Chairs with hydraulic mechanisms allow for more flexible adjustments.
Backrest Adjustment
Choose an office chair with a tilted backrest. This feature allows users to adjust the angle of the backrest to suit a comfortable sitting posture and support the back well.
Lumbar Support (Lower Back)
A good office chair must support the lumbar area, specifically the lower back. This support is critical to prevent strain on the lower spine, especially if you sit for long periods.
Adjustable Armrest
The height-adjustable armrest feature is also an added value. With an ergonomic armrest, users can rest their hands comfortably, reducing tension on the shoulders and arms.
