This my "go-to" resonane calculator. It also tells you how to make your coil. It gets you very close.

A good site on coil winding:

The parent is full of great information:

I'm also a fan of online calculators for the same reasons. In lieu of that, many radio books will have a nomograph like Rune mentions that will give you a pretty close idea. I don't think many people do the actual math these days.

It would be a nice idea to have a sticky on this page with some links and a printable nomograph.
