Eyebrow mapping: start, arch and tail
The tool draws styling guides from the outer nose region through three eye landmarks. The inner-eye line gives a starting reference, the iris line an arch reference, and the outer-eye line a tail reference. It compares those guides at the observed brow height. These are adjustable styling conventions, not mandatory positions for every face.
Read relative offsets, not uncalibrated millimetres
Offsets are reported as a percentage of the distance between iris centers. This makes their scale explicit without claiming an absolute millimetre measurement from an uncalibrated selfie. The overlay is more useful than chasing zero: natural brow growth, expression and styling preferences affect which guide you choose to follow.
Take a useful brow mapping photo
Keep your brows relaxed, face the lens straight on and move hair away from the forehead. Heavy brow makeup can shift the apparent boundary, and a raised brow changes the arch position. Inspect whether the marked brow points match the visible hair before using the map as a styling reference.
Frequently asked questions
Does eyebrow mapping tell me what to pluck?
No. It provides reference lines, not a hair-by-hair grooming instruction. Natural growth and your chosen style still matter.
Why do my brows have different offsets?
Expression, head turn, actual brow shape and landmark placement can all contribute. Retake a neutral photo before interpreting a small difference.
Is the brow mapping tool free?
Yes. All six guide offsets and the annotated photo are available without an account.
