Which rim tape size fits my bike?
I’m pretty sure the wheel size you quoted is what’s written on your tires i.e. ISO 622 rim (aka 28”, 700c) with a 37mm wide tire. 

You need the internal width between the flanges of your rims to know what size rim tape to get. This is easy to measure with the tire and tube removed. 

I.e. 22-622 rim tape is for ISO 622 diameter rims with 22mm internal width.
