Office Chair and Workstation Sizes

The common size ranges for office chairs and workstations are as follows:

Office Chair Sizes The size design of office chairs needs to balance ergonomics and comfort, with core parameters including seat height, width, depth, and backrest height.

• Seat Height: Typically ranges from 40 cm to 50 cm, adjustable according to the user's height. The adjustment standard is to sit with both feet firmly on the ground and be able to easily insert the palm under the thighs to avoid leg suspension or compression.
• Seat Width: The common range is 45 cm to 55 cm, ensuring sufficient support for the hips and both sides of the thighs to reduce fatigue from prolonged sitting.
• Seat Depth: Generally ranges from 35 cm to 45 cm, ensuring that the thighs are fully in contact with the seat surface and leaving a gap of about 2-3 fingers between the back of the knees and the edge of the seat to avoid compressing blood vessels.
• Backrest Height: The backrest of a medium-height backrest chair usually does not exceed the waist position, with a height range between the waist and shoulders, providing waist support while avoiding restricting shoulder movement.

Workstation Sizes Workstation sizes need to meet the requirements for placing office equipment and personnel movement, with common types including regular partitioned workstations and L-shaped combined workstations.

• Single Size of Regular Partitioned Workstation: The width ranges from 1.2 meters to 1.4 meters, which can accommodate basic equipment such as a standard office desk (about 1.2 meters wide), a computer, and a filing cabinet, while leaving some space for movement. The aisle width should be at least 60 cm to ensure that personnel can pass without feeling crowded and avoid collisions or obstructions.
• Size of L-shaped Combined Workstation: The common specification is 1.5 meters × 1.5 meters. This type of workstation maximizes space utilization through corner design and is suitable for scenarios where multiple devices need to be operated simultaneously or work areas need to be switched frequently. Its size can be flexibly adjusted, but it is necessary to ensure that the width of the main work area (such as the computer placement area) is not less than 1.2 meters, and the width of the secondary work area (such as the file organization area) is not less than 0.8 meters.

Size Selection Recommendations The sizes of office chairs and workstations should be comprehensively considered based on the user's body shape, work habits, and spatial layout. For example, taller individuals need to choose an office chair with the upper limit of seat height (50 cm) and pair it with a wider workstation (such as 1.4 meters); while small offices with limited space can prioritize choosing a regular workstation with a width of 1.2 meters and a compact office chair (seat width of 45 cm). Reasonable matching of sizes can effectively improve work efficiency and comfort.
