Pull hair away from the face
Stand in front of a mirror
Trace the outline of the face with a washable marker or lipstick
Measure forehead width
Measure cheekbone width
Measure jawline width
Measure face length from hairline to chin
Compare the measurements
Identify the widest part of the face
Check whether the face is longer than it is wide
Check whether the jawline is sharp, rounded, or soft
Check whether the forehead is wider than the jawline
Check whether the cheekbones are the widest point
Check whether the face is nearly equal in width and length
Match the features to common face shapes
Oval: face length longer than width, balanced proportions
Round: face length and width similar, soft curves
Square: forehead, cheekbones, and jawline similar in width
Rectangle: face longer than wide, similar width throughout
Heart: wider forehead, narrower jawline, pointed chin
Diamond: narrow forehead and jawline, widest cheekbones
Triangle: narrow forehead, wider jawline
Use a front-facing photo for comparison
Repeat the check in good lighting
