Getting my compressor hooked up. Will 1/2" pex be big enough or do I need to go to 3/4"?
I just use 1/4" air hose works fine, mine is about 15’ long.

I would go 3/4". I ran 3/4" PVC from compressor shed outside of my shop to auxiliary tank (for volume) inside and put several outlets for easy access. When you start big and go smaller gives you volume then pressure. Same as water lines. Go from a 4" line (volume) down to a 3/4" or even 1/2" (pressure) will give you water pressure.
