Go somewhere and try typing on any that you are considering. Usually the biggest issue is having the fingers getting cramped together too close to be comfortable when typing. If you get a wireless them make sure it does not have any interference with other devices around the computer. As an example years ago my "smart phone" used to beep and howl when close to the PC mainly due to my Logitech mouse/key board I think and finally after a phone upgrade that quit.
