How do I measure head height?

Measure from the nape of the neck (hairline) to the crown of the head along the side of the head. Average adult head height is 20-24cm. This measurement determines where the fade lines should sit for proportional results.

Where is the occipital bone?

The occipital bone is the prominent bump at the back of the head, typically about 55% of the way up from the neckline. It is the most important landmark for fading because the head shape changes angle here. The fade blending is most visible around this point.

How does hair density affect the fade?

Thicker hair needs wider blending zones because the guard transitions are more visible. Thin hair blends more easily and needs narrower zones. Adjust your blending technique accordingly — thicker hair may need additional passes with the clipper lever open.

How many clipper passes does a good fade need?

Each blending zone typically needs 2-4 passes: initial cut, lever technique (open/close), flick-out motion, and final check pass. Thicker hair needs more passes. A full fade with 3 zones might require 9-12 passes total.

How We Calculate This

This calculator determines fade line positions as percentages of head height, then calculates blending zone widths adjusted for hair density.

Fade line positions

Low fade: starts at 15%, ends at 30% of head height
Mid fade: starts at 30%, ends at 50%
High fade: starts at 50%, ends at 70%
Skin fade: starts at 10%, ends at 25%
