Jill it can be anything you want it to be.
As for fabric - Let me see what I can come up with.
For one quilt block
An 1/8th yd should suffice for most template sizes unless you are going really big.
Okay - for a 2 1/2" template -
this is at least this size. I didn't add any wiggle room so that is up to you.
I also figured this based on cutting squares into triangles. This doesn't take into acct if you rough cut. so add a bit more if you are rough cutting.
Red - 6" x 22" or a 12" x 12" will work
Blue - 10" x 22"
Green - 8" x 20"
