The three most common layouts are full-size, tenkeyless, and 60-percent. Full-sized keyboards include a tenkey number pad which, of course, makes them the widest option. Tenkeyless keyboards ditch the numpad for a more compact look, while 60-percent keyboards drop everything to the right of the Enter key to achieve a very small footprint. There’s no right or wrong answer. Your choice will come down to personal preference.
