Typing is a physical matter and the only way to find out if the keyboard "fits" is to go hands on as best you can.
Visit various big box stores, try keyboards via friends and family. Litterallly going hands on is the only true solution to finding a good fit.
Otherwise, you will simply need to take the time to physically adjust to the keyboard at hand and, overall, your typing speed will improve.
