Reference data
These are the pages we maintain rather than write once. Each one states where its figures come from, when they were last checked, and what would make us change them.
How to read these tables
- Derived figures are calculated from published constants and shown with the formula. They are exact.
- Manufacturer-stated figures are transcribed from product documentation. They are as accurate as the manufacturer is.
- Framework figures, such as our weight classes and grip ratios, are editorial judgements. We label them and explain the reasoning.
- Every table is sortable by clicking a column heading, and works with the keyboard.
The tables
- Game sensitivity constantsYaw values for every supported title, with the engine, a verification procedure you can run yourself, and the games we exclude with reasons.
- Mouse databaseWeight, length, width, height, hump position, sensor, connection and polling for the shapes that define the market.
- Keyboard switch databaseActuation point, total travel, operating force and peak tactile force, including Hall effect ranges.
- GlossaryEvery term used on this site, defined precisely, grouped by area and linked to the full explanation.
Why these are curated rather than exhaustive
A table listing every gaming mouse on sale is not a reference, it is a search engine with worse filtering. The mouse and switch databases follow one inclusion rule: an entry earns its place by representing a distinct shape, a distinct size band, or a distinct mechanism. A fourth mouse with the same shell dimensions as three already listed adds nothing you could act on.
This has a cost worth stating plainly: a product you own may not be listed. We think that is better than a table too long to read, and it means every row is there for a reason we can articulate. See editorial standards for the full policy.
How these tables are kept current
- Game constants are re-checked when a supported title ships a major input or engine change. Source-family values have been stable for over two decades and are unlikely to move.
- Mouse and switch specifications are re-checked against manufacturer documentation on a rolling basis, and immediately when a reader reports a discrepancy.
- Any change that alters what a reader would conclude is logged with a date on the corrections page.
- Community-established figures, as opposed to primary-source ones, are labelled as such on the page rather than presented with equal confidence.
If a figure here disagrees with a manufacturer's current documentation, or with a measurement you have taken, we would like to know. The corrections page explains what makes a report easy to act on.
