Don’t Leave Home Without your VESA: Monitor Mount Sizes

“Will this arm fit my monitor?”

This is one very common question we encounter when discussing arms and mounts over the phone with customers. The good news is that in most cases, the answer is an easy “yes,” due to the fact that there is a degree of standardization among monitor manufacturers. Today, however, I will go into some detail and look into some special cases.

Monitors usually mount via four screws on the back of the monitor that form a square. The length of the distance between these screws (i.e. the sides of the square) is defined by the VESA standard. The most common sizes are 75 mm x 75 mm and 100 mm x 100 mm. Mounting plates to fit either of these sizes generally come with all our monitor mounts by default. So as I said above, the answer to whether a given monitor will fit a given arm is usually yes. There are a few instances in which this is not the case, however.

One of these is if you are using an iMac or other Apple monitor. Like many Apple products, their mount size is proprietary. Innovative offers some arms like the iLift that work with them. To use them with other arms, you have to buy a VESA adapter directly from Apple that will allow them to mount to a standard size 100x100 VESA plate.

Another special case is the 200 mm x 100 mm mount. Humanscale offers some arms, notably the M7, that can accommodate this special size. Innovative arms can do this as well. Innovative is the only manufacturer we carry that can accommodate another special size, 200 mm x 200 mm. In either case, we will need to special order the arm, so please call us to order.

We are happy to answer any questions you may have, so please call or chat with us. We cannot find the VESA mount size on your monitor, however, so please have that ready before you contact us. The easiest way to do this is to find your monitor’s instruction manual, or to contact the manufacturer.

Monitor mounts can be a little tricky, but the good news is that usually, they work with our monitor arms as-is.
