Hair Length Guide & Calculator

For straight hair, pull a strand taut from the root and measure to the tip. For curly hair, gently stretch a curl straight and measure — this gives your true length.

You can optimize growth by eating a protein-rich diet, reducing heat damage, using a silk pillowcase, and getting regular trims to prevent breakage.

The awkward stage hits between ear-length and chin-length (4-6 inches). Hair is too short to tie back but too long to style easily. This phase usually lasts 3-6 months.

Match length to your proportions, then preview on your photo. Round faces often elongate with medium-to-long layers below the chin; square faces soften when length clears the jaw; heart faces need lower fullness; oblong faces usually want bangs and side width; oval faces can wear most lengths. See Styles length × face guides, or try lengths in Hairstyle AI.

Trimming doesn't affect growth rate, but regular trims prevent split ends from causing breakage, which helps you retain more length over time.
