Proper cockring sizing is extremely important. Too tight can mean injuries, too loose means it won't be effective. 

To measure, get a piece of string or ribbon and wrap it around the base of your cock when you're hard; you need to measure at the base of your penis and behind your balls. 

Then divide the length by 3. This will give you your diameter measurement.
