Competitive gaming gear, measured
Most gear advice is a ranked list of things somebody was sent for free. This site starts from the numbers instead: engine constants, manufacturer specifications, and the physics of a signal travelling from your finger to a pixel. Where a question has an exact answer, we built a calculator. Where it does not, we say so.
14games with published yaw constants, so conversions are exact rather than approximate
24mice in the shape reference, with dimensions you can match to your hand
18keyboard switches with actuation, travel and force side by side
8calculators that show their working, so you can check the maths yourself
Start with a calculator
Each one runs in your browser, keeps nothing, and prints the formula it used underneath the answer.
- Sensitivity converterMove a sensitivity between 14 games at any DPI, with the cm/360 it preserves.
- eDPI and cm/360 calculatorWork forwards from a sensitivity, or backwards from the distance you want.
- Mouse size finderEnter hand length, width and grip style. Get the shell dimensions that actually fit.
- Input lag budgetBreak your click-to-photon delay into six stages and find the worst one.
- FPS and refresh rateSee what a refresh rate upgrade is worth at the framerate you actually get.
- All eight toolsMousepad sizing, ADS multipliers, monitor distance and pixels per degree.
The reference tables
Sortable, sourced, dated. These are the pages we maintain rather than write once.
- Mouse shape databaseWeight, length, width, hump position, sensor and polling for the shapes that define the market.
- Keyboard switch databaseActuation point, total travel and operating force, including Hall effect ranges.
- Game sensitivity constantsEvery yaw value we use, the engine it comes from, and how to verify it yourself.
The ten things that actually change your aim
In the order we would fix them, ranked by effect size per pound with free changes ahead of paid ones at equal effect. This is the site's core argument, and every cluster below is one link in it.
| # | Fix | Why it sits here | Cost |
|---|---|---|---|
| 1 | Settle your sensitivity and stop moving it | Nothing else compounds. Every hour on a stable cm/360 is deposited; every change spends the balance. | Free |
| 2 | Give yourself the desk space your sensitivity needs | A 45 cm/360 aim on a 35 cm pad means repositioning mid-fight, so every correction starts from a hand position you did not choose. | Low |
| 3 | Kill your render queue | Frequently 20 to 50 ms, which is more than every peripheral upgrade you are considering combined. It is a checkbox. | Free |
| 4 | Get to 1000 Hz polling and clean your input path | 125 Hz to 1000 Hz removes 3.5 ms, and it makes every calculation on this site actually apply to your machine. | Free |
| 5 | Fix your desk and chair height | A too-high desk keeps your shoulder elevated for every hour you play, which costs repeatability before it costs comfort. | Free |
| 6 | Match the mouse shape to your hand and grip | The first item that costs money, and the one that matters most among those that do. Fit beats sensor, weight and polling combined. | Medium |
| 7 | Fix your audio chain and in-game sound settings | Your monitor covers 45 degrees. Your headphones cover the other 315, for a fraction of the price. | Low |
| 8 | Raise your framerate | Shrinks two latency terms at once and improves motion clarity. Judge it on 1% lows, not averages. | Variable |
| 9 | Raise refresh rate, once framerate can feed it | Real and large up to about 240 Hz. Buying 480 Hz on a machine that renders 140 fps is buying repeated frames. | High |
| 10 | Everything else, including mouse weight | All real, all small. Weight matters above 80 g and is largely settled between 50 and 65 g. | Variable |
The full reasoning behind this order, including the six situations where we would reorder it. The free items are collected in the settings checklist, which takes about twenty minutes end to end.

How this site works
Three commitments, and the pages that hold us to them.
- Every number has an originDerived, manufacturer-stated or measured. Each figure on the site is labelled with which.
- No paid placementsNothing on this site is ranked, included or excluded because of a commercial relationship.
- Corrections are publishedWhen we get something wrong, the fix is logged on a public page with a date.
