Easy Face Shape Test 

Here are the directions:
Materials: Ruler and calculator
A: Measure from your crown to your chin.
B: Divide that number by 3.
C: Measure from the bottom of your nose to the bottom of your chin.
Results:
If B is greater than C, then you either have a long or a square face.
If B is less than C, then you either have a round face or a diamond face.
If B an C are equal, or close, then you either have a heart shaped face or an oval face. If your chin is pointy, then you are heart shaped. If your chin is round then you have an oval shaped face.
