Frequently asked questions
How does InputArena compare mice and keyboards?
We collect the full published specification of every product — sensor, DPI, polling rate, weight, switch type, battery life and more — then let you place any two or three side by side. Winning values are highlighted on each row, and our editors add a rating out of 10 so you can judge quality at a glance.
Are the ratings and comparisons unbiased?
Yes. Our ratings are based on the listed specifications and hands-on editorial judgement, not on sponsorships. We clearly separate measured specs from opinion, and comparisons are generated from the same data for every product.
What free tools does InputArena offer?
You can test and calculate your mouse DPI and eDPI, cm/360, click speed (CPS), and both mouse and keyboard polling rates — plus keyboard ghosting and rollover checks. Everything runs in your browser, free and without an account.
Which specs matter most for gaming?
For mice: weight, sensor and max DPI, and polling rate. For keyboards: switch type, actuation, polling rate and layout. Our comparison tables surface exactly these so you can weigh the trade-offs for your grip, game and budget.
