Eyebrow Shapes: The Complete
Guide to All 6 Types
Eyebrow shape is classified by arch height, arch position, and overall thickness. There are 6 primary types: straight, curved, S-shaped, rounded, angled, and flat/thin.
About this guide: Natural brow shape and groomed/shaped brow are two different things. This guide describes the natural growth pattern — grooming can adjust how it reads, but the underlying shape provides the starting point for most shaping advice.

Frequently Asked Questions
How many eyebrow shapes are there?
This guide covers 6 primary eyebrow shapes: straight, curved, S-shaped, rounded, angled, and flat/thin. Arch height, arch position, and overall thickness are the main distinguishing factors.
Does eyebrow shape relate to face shape?
Many brow-shaping guides recommend pairing eyebrow shape with face shape — for example, a softer curved brow for a more angular face, or a more defined angled brow for a rounder face — though personal style and natural brow growth pattern matter just as much as strict matching rules.
How do I find out my natural eyebrow shape?
Look at your brows before any shaping or makeup, in a well-lit mirror. Check whether the arch peak is sharp (angled), gentle (curved), minimal (straight), or whether there's a visible double-curve (S-shaped). The free AI eyebrow shape detector identifies this from a photo automatically.
Can eyebrow shape be changed through grooming?
Shaping, tweezing, and brow makeup can significantly adjust the apparent arch and thickness, but the natural growth pattern and hair direction underneath still influences how easily a brow holds a given shape.
