01
Lightness according to use
Weight dictates the portability of the tablet and keyboard combination. Market models range from two hundred and eighty-one grams for the lightest to one kilogram forty for the heaviest, with a median around four hundred and twenty-nine grams. A light keyboard slips into a bag without burden, ideal for working on the move. Heavier models often incorporate reinforced protection or an additional battery. On each product page, the lightness score positions you immediately: the longer the bar, the lighter the keyboard. Favour contained weight if you frequently change work locations.
Market median: 428.5 g

Number of keys for typing
The number of keys determines ergonomics and directly accessible functions. Tablet keyboards range from sixty-five keys for compact formats to eighty-one keys for full configurations, with the median around seventy-nine keys. A complete keyboard offers a shortcut pad, function keys and sometimes a numeric keypad. Reduced models prioritise compactness at the cost of combined keys. The displayed score reflects this count: the longer the bar, the more keys the keyboard offers. For intensive typing or demanding software, aim for a high key count.
Market median: 78.5
03
Thickness for storage
Keyboard thickness influences its bulk in a bag and visual comfort in use. Recorded measurements extend from nine millimetres for the thinnest to one hundred and twenty millimetres for the thickest, with a median at fourteen millimetres. A thin keyboard stores easily with the tablet, disappears in a bag and offers a natural typing angle. Thicker models sometimes incorporate an adjustable stand or protective case. The compactness score progresses as thickness decreases: the longer the bar, the thinner the keyboard. Seek thinness if you value discretion and overall lightness.

Compatibility and connection
Check that the keyboard matches your exact tablet model, especially for magnetic attachment or pogo pin systems. Connection can be wired, Bluetooth or proprietary: Bluetooth offers extended compatibility but requires regular recharging, while proprietary connections ensure instant pairing and sometimes direct power supply. Some keyboards offer multiple Bluetooth profiles to switch between devices. Also anticipate key layout according to your language: a French AZERTY keyboard differs from an English QWERTY or German QWERTZ. Announced battery life varies according to usage intensity and any backlighting.
