Office Chair Dimension Calculation:
Before buying any office chair you must have looked at the dimensions of the chair and have decided if the chair will fit into your workspace perfectly.
The picture below will tell you how the Length, width, and height of any chair are calculated.
The length of any chair is the distance from the backside and front side of the chair. If your office chair has legs, you can calculate the distance between the legs to calculate the length of your chair.
However, if your chair has wheels, you can just measure the distance between the wheels and find the length of your office chair.
To find the width of your chair, you have to measure the distance between the legs of the left and right sides of your chair. You can also find the width by measuring the distance between the arms or take the distance between the wheels from the left to the right side.
The height measurement of any office chair is quite simple. Measure the distance from the top end of the chair to the bottom of the chair, and you will get its height.
If your chair has a headrest, measure up to the top of the headrest. But if your chair doesn’t have a headrest, you have to measure up to the top end of the backrest.
