Pad sizing confusion, help!

Hey fellas Just getting back into goaltending after a 15y hiatus. I just want to get back on the ice, miss it a lot and life isn't as hectic anymore. I am trying to figure out my pad size. I have seen a few methods. According to this formula - measure ankle to knee, knee to mid thigh and skate size I am a 28. I am 5"5ish with my skates on. Does this make sense? I want to play shinny and some beer league. I didn't really want to go get measured somewhere as I don't intent on buying a new set. Thanks ahead of time!

Also, if that is my size.. that would be an intermediate set & not a senior set correct?
