3 Reasons a Full Desk Mat Overhang Works Better on Small Desks
A full mat that overhangs slightly is better than a smaller pad that leaves your forearms resting on the desk edge. The issue isn’t the overhang — it’s the exposed edge.
On a 60x30cm desk, a smaller pad means your arms touch raw desk surface or the sharp front edge. That gets uncomfortable fast, especially if you type or mouse a lot.
A full mat that hangs over by 1-2cm gives you a cushioned surface everywhere your arms land. Avoid going bigger than 3-4cm, or the mat will slide around and annoy you.
