Do you need a mouse pad or desk mat?
It’s important to consider whether you need a desk mat. These days, many mouse sensors work just fine on a desk surface. What you lose in that scenario is feel and precision. A desk mat gives a sensor an even color and texture on which to track, and it also makes it feel more consistent as you’re moving your mouse around. If you go for a larger mat, it even gives you a soft place to drop accessories and your wrists.
