Adding a subpanel to a garage !
I want to add a subpanel in my garage. I would like to have two 220v circuits and probally two or three 110v circuits for outlets. One of the 220 circuits will be dedicated for a 80 gallon compressor. The other for a welder or whatever down the road. I would like to know what amperage subpanel I should get? What size breaker should I get to feed the subpanel? I have the wire already to feed the subpanel. Any help would be very appreciated.

Is this an attached or detached garage?

Welcome to the forums.
And what size is that as it dictates everything ?

That sounds like 8-3 NM-b w/ground. #8 cable will yield 40A of power.
You would use a 2P40A breaker.
That would be rather small for a welder.

The wire was given to me so I'm not out anything if it can't be used. So let's start over since I was ahead of myself. The compressor is a 230v/24A/1 phase, but can double the amps when the motor starts. Not sure on what a welder would need as far as amperage. And the other outlets I wouldn't think would exceed 20 amps.

Ok I have a 100 amp subpanel and I would like to be able use all amperage available at one point or another. So what size feeder breaker can I install in the main panel? and what size and type of wire should I use to provide 100 amps? Routing the wire through the house to the garage would be very difficult, can I route it outside to the garage if I use conduit? That is alot shorter I would think and alot easier but I'm not sure if that's acceptable. Just looking for some advice. Thanks

Sure you can go outside in conduit. Use a 100A breaker and use 1-1-1-3 Al SER and depending on how it's run you may not need much conduit at all, only where protection is needed. Make sure your main panel can take a 100A breaker, but most likely it can.

SER cable cannot be used underground.
Pavs1029, when you say outside, are you asking about above or below ground?
