F10 vs F20 sizing

[Yayoe10]

For people that have used both mask was there a sizing difference between the two? I'm a medium in F10 so would I be a medium in F20? Just wondering if the sizing changed between the too. Don't have a printer to print out guide. Will try to go to staples after work tho but just wanted to ask.

I have an F10, but have not tried the F20. Someone measured the medium F20 for me and it was the exact same width as the F10 at 3.75". Using the Resmed fitting gauge they still recommend the medium for myself. I'd say the size hasn't changed. Someone will have both masks and confirm.

I have both and have tried medium and large in both. I use a large with the F10 and a medium with the F20. The large F20 had too much leakage at the top.

Tell you the truth I don't really use the F20 much, it felt like I had an inner-tube stuck to my face. It seems a lot more bloated to me since the cushion puffs out more.
