This is just a general guide. Actual pipe sizes may vary by manufacturer, but this should give a general idea of how large a hole needs to be drilled, what will fit, and help determine what pipe size you are dealing with if you can't find any markings.
Always remember to check your local jurisdictions for the trap arm lengths because sometimes they may differ from the standard IPC/UPC. Some places have a 72" limit for the 2" pipe, and larger pipes that are sloped at 1/4" per foot instead of 1/8" will have shorter runs.
The developed trap arm length can not exceed one pipe diameter because it will block air flow and create a vacuum.

And here is a PEX sizing chart....
