Better yet, just take a yardstick and measure the following:

Wingspan
wing root chord
wing tip chord
leading edge sweep back at tip

stabilizer span
stab root chord
stab tip chord
leading edge sweep back at tip

distance from LE of wing to LE of stab along fuselage.
Easy to do and takes a couple of minutes, not 20, and no great skills required.
Then plug those 9 measurements into the geistware application that has already been suggested twice above. Click on the button and you got your answer. And you'll be able to do it for yourself next model, and the next after.
