Size · 11 keyboards
A full-size or 100% keyboard has every key, with the function row, a navigation block, the arrows and a full numeric keypad. US boards have 104 keys and most others 105. It's the standard office layout and the one to pick for heavy number entry. The trade-off is width, which pushes your mouse further out. On a used one, check the numpad keys and Enter for wear and stabilizer rattle.
