To measure scale length, just measure from the nut to the middle of the 12th fret, then double it.

If you mean actually calculating scale length and all the fret distances, you need to do a lot of math and geometry. (Pythagorean theorem, mostly.)

Or, you can use a simplified method, described here.

Darren is right on the money!

If you did need a fret calculator though you can use this one which will save you time and trouble.

If you simply want to know what the scale is of a particular guitar is without doing any math, just measure the distance from where the string leave's the nut to where it touches the bridge.

In most case's your only going to find the following scales.

25.5" scale found on almost every modern day bolt on strat style neck.
24.75" scale found mostly on Gibson necks.
25.4" scale found mostly on Martin acoustics.
25" scale found mostly on PRS
