If you need to find out whether it is 22.2 or 25.4, wrap a piece of string around it, and mark where the string touches itself.
Uwrap, and measure the string. A 25.4 will measure 79.75 mm. A 22.2 will measure 69.7 mm.
If you are looking for some other recommendation, hopefully someone else will chime in.
