About this tool
Enter your monitor's weight, VESA pattern and size, then the arm's published weight range, supported VESA patterns and screen-size limit, and your desk's thickness and type. The checker flags every mismatch and warns about common problems such as arms that are too strong for a light monitor, glass or hollow desks and missing VESA holes. Always use the figures printed on the product page or in the manual.

Frequently asked questions
What is VESA?
A standard pattern of four screw holes on the back of a monitor, measured in millimetres, such as 75 x 75 or 100 x 100. The arm's head must support the same pattern.
Why is there a minimum weight?
Gas-spring arms are tuned for a weight range. A monitor that is too light makes the arm rise instead of staying where you put it.
Is the Monitor Arm Compatibility Checker free?
Yes. Monitor Arm Compatibility Checker is completely free with no sign-up, limits or watermarks.
Is my data private when I use the Monitor Arm Compatibility Checker?
Yes. It runs in your browser, so your input is not uploaded to our servers.
