Air line setup

Hey guys, getting started setting up my painting space. I plan to run an air brush right up to a full size gun with a 2.5 needle/tip.
Jim says 3/4ID line from the compressor to the reg/dryer/trap is a good plan. Now what should I run for my 50ft hose and fittings. 3/8?
Thanks for any help.

    Are you painting buildings? The biggest tip I have used was a 1.8 and that was used to paint trucks...

    Your airlines should be as short as possible, but allow you to move around your product. Hose is a terrible way to supply air, but it's necessary. Run hard pipe as far as you can, and then match the hose to the air consumption of the gun.

    Thanks for the feedback 👍
    No buildings thank god lol, the 2.5 would only be for a flake gun. Also other than the paint guns I need to supply a small/medium blasting cabinet and eventually a vapor blaster cabinet. Now that one will require a new compressor though lol.

    We used to run "Bass Boat Flake" through a 1.8, but I was really just wondering what you could have needed that size tip for.

    Run the 3/4" all the way up to the regulator for the drop or gun. AT that point you can drop to a hose fitting after the regulator...or maybe some 1/2" line then the fitting? Either way keep the line as large as possible up to the point of use is the best advice I can give...
