Start With Length
Match the wrist rest to the keyboard footprint.
For most setups, the easiest route is to measure the keyboard from left to right and choose the closest preset size. If your board has an unusual layout or you want a more exact fit, use the custom option up to 50 cm.
Think About Height
Height changes both comfort and visual weight.
A lower profile tends to feel lighter and more minimal, while a taller profile can feel fuller under the wrist and more substantial on the desk. The custom builder allows heights up to 2.2 cm when you need something more specific.
