Add the tip chord to either end of the root chord. Add the root chord to either end if the tip chord. Cross all four corners. Where the meet is the Mean Aerodynamic Chord or MAC . Draw a line at that point from leading edge to trailing edge. Now measure back, as Cafeen man says, 15 to 20 % thats your CG. Just to check, Make yourself a 12 in glider of the same planform, tilt the trailing edge up a bit to act like up el. trim, or reflex, if you will. Add nose weight for a fast flat glide. Cg will be the same % for the big one.

Wow! Thanks for the diagram, I need to find the CG for a delta and I almost blew my cerebral cortex trying to figure it until the picture made it all clear.[8D]
