Look for a sight that builds them. They should have a diagram of each truss. They won't tell you specific dimensions, but if you look at one that is about the same size as you need, you can just approximate the other dimensions. It's the pattern of bracing that is important, and the lumber size.
Edit: While buying trusses is usually cheaper, I'm not sure that building them is. With trusses, you lose attic space because of the braces, but you can put them on 24" centers, instead of 16". The biggest reason to use trusses is labor saving on the job site.
If you use regular rafters, you can use 2x6 spruce on 16" centers. Depending on the width of the building and the pitch of the roof, you can gain usable attic space by using rafters instead of trusses. If the width is only 20', and a 4/12 pitch, however, you'd only have 40" at the ridge, so you might as well use trusses.

Building roof trusses is not the difficult part. Most municipalities require the design calculations for roof trusses. If you don't know how to calculate the trusses you would be wasting your time, you can't use them.

Sure, lots of them -- I used them to build the roof trusses for the roll-off roof observatory I just finished :)
I put one below, but just do a search on "roof truss how to build" and you'll find dozens of sites.
