#3 copper or #1 aluminum, minimum, and make sure you run four wires (2 hots,
neutral, and ground) -- but why 100A in a shed??

Price out that #3 copper and you may find that a 30A or 60A service will
suite your needs. I have 30A 240V in my garage/shop and it handles al my
lighting and power tool needs.

Even 60A should be plenty to run stuff like arc welders and air compressors.
But it's your shed, and your money.
I'm just sayin'...
