Stencil lengths in the stencil catalog are the blue line lengths shown in the diagram at left.

The diagram shows where the eyebrow should begin and end. Line A is a straight line from the outside of your nose to the inner corner of the eye. The brow should start here. Line B is a straight line from the inner corner of your nose to the outer corner of your eye. The brow should end at point B. The "blue line" (the line between points A and B) should be measured using a piece of string. This will allow for facial curvature. The stencils are a light durable flexible plastic. They will curve around any shape.

This is a guide - extensions to lengthen can be done freehand when application is complete or q-tips can be used to remove powder from a brow that is too long.
