Speed Calculator

I'm working on the motor selector and have some questions. I need to group all the 540 can motors by S, L, XL, and XXL size.

Would the Lehner Basics be considered S size?
Would the Lehner Basics XL be considered L size?
Would both the LMT 1940 and 1950 be considered XL size? Or is the 1940 more L size and the 1950 XL size?

Argg! LMT has too many sizes! Better question:
Where do the following motors fall in the S, L, XL (and maybe XXL) size rating?
1920 S?
1930 L?
1940 XL?
1950 XXL?
