3 Reasons a Larger Mousepad Matters at 400 DPI

Lower DPI requires more physical movement At 400 DPI, a 45cm pad gives only about 35cm of usable width, which covers roughly half a 1080p screen. You will need to lift your mouse frequently to turn around in an FPS.

A bigger pad reduces lifts and improves aim A 90cm pad doubles your usable space. You can flick, track, and reposition without hitting the edge as often, leading to smoother aim and less frustration.

The main tradeoff is desk space and cable management A large pad takes up more room and may cause your mouse cable to snag. These issues are manageable if you have the space.
