Full desk mat vs smaller pad: Full mat with slight overhang wins for comfort on small desks
A full mat that overhangs 1-2cm is better than a smaller pad because it cushions your forearms instead of leaving them on the raw desk edge. On a 60x30cm desk, a smaller pad exposes your arms to sharp edges, which gets uncomfortable fast. Just avoid overhang beyond 3-4cm or it’ll slide around.
