100% Private — runs in browser 478-point landmark detection 6 eyebrow shape types Personalised styling tips
What is my eyebrow shape? Your eyebrow shape is determined by three measurable traits: how high the arch rises relative to the brow's length, where along the brow that arch peak sits (front, middle, or back third), and how thick the brow is relative to its length. This free tool measures all three from a single photo using on-device AI, then classifies your brows into one of six recognised eyebrow shape types.
4 Steps

How the Eyebrow Shape Detector Works

Four steps from photo to personalized styling tips — all processed locally on your device.

Step 1

Upload or take a photo

Upload a clear, front-facing photo or use your device camera directly in the browser. Keep your eyebrows fully visible and free of hair.

Step 2

AI maps 478 facial landmarks

MediaPipe Face Landmarker runs entirely in your browser and locates 478 precise points — including the full upper and lower brow arc for each eyebrow — without uploading any data.

Step 3

Arch, position, and thickness are measured

The analyzer measures arch height relative to brow length, where the peak sits along the brow (front, middle, or back third), and the length-to-thickness ratio.

Step 4

Your eyebrow shape is classified

Based on those measurements, your eyebrows are classified into one of six types: Straight, Curved, S-Shaped, Rounded, Angled, or Flat/Thin.

6 Eyebrow Types

All Eyebrow Shapes & Types: Which One Are You?

Six distinct eyebrow shapes classified by arch height, arch position, and length-to-thickness ratio.

Straight

Nearly horizontal from inner corner to tail with minimal arch — the classic soft brow.

  • ·Fill with feathery, light strokes
  • ·Keep colour close to natural shade
  • ·Avoid carving in an arch

Curved

A gentle, rounded peak near the middle third — soft and universally flattering.

  • ·Follow the natural curve when filling
  • ·Darker shade at the peak adds definition
  • ·Set with a light brow gel

S-Shaped

A sharp, high arch toward the outer third — dramatic and sculpted.

  • ·Use crisp, defined strokes
  • ·Highlight beneath the peak
  • ·Hold the angle with pomade or wax

Rounded

A low, evenly distributed curve with no single sharp peak — soft and youthful.

  • ·Fill evenly across the whole brow
  • ·Keep the tail soft, not sharply tapered
  • ·Warm brown tones suit this shape

Angled

A distinct, sharp corner creating a bold geometric brow line.

  • ·Use straight, precise strokes
  • ·Fine-tip pencil defines the corner
  • ·Set with strong-hold brow gel

Flat/Thin

Minimal thickness and low arch — delicate and benefits most from strategic filling.

  • ·Hair-stroke technique with a fine pencil
  • ·Build volume gradually with powder
  • ·Fibre gel adds density

How to Photograph Your Eyebrows

A good photo makes a significant difference. Follow these tips for the most accurate eyebrow shape result.

Face the camera directly

Look straight ahead — chin level, not tilted up or down. Even a small angle changes the measured arch position.

Relaxed, neutral expression

Avoid raising your eyebrows or frowning — a raised brow temporarily changes the measured arch height.

Even, natural lighting

Soft daylight from in front is ideal. Side lighting or heavy shadows across the brow area can affect the detected contour.

Push hair away from brows

A fringe, hair strands, or a hat brim covering part of your eyebrows will reduce accuracy — clear the brow area fully.

Single face in frame

The analyzer works best with one person clearly visible. Make sure no other faces are partially in the frame.

Minimal brow makeup

For the most accurate reading of your natural shape, photograph with little or no brow pencil, powder, or gel.

Unexpected result? Retake the photo in natural light, facing the camera directly with a relaxed expression, brows visible and free of hair. Small changes in angle or expression can shift the classification.

Frequently Asked Questions

Everything you need to know about eyebrow shapes and how the detector works.

What is an eyebrow shape detector?

An eyebrow shape detector uses AI facial landmark detection to measure the proportions of your eyebrows from a photo — including arch height, arch position, and length-to-thickness ratio — and classifies them into a named eyebrow shape type. The classification is paired with personalised grooming and makeup tips.

How many eyebrow shapes are there?

This tool classifies eyebrows into six types: Straight, Curved (soft arch), S-Shaped (high arch), Rounded, Angled (sharp arch), and Flat/Thin. These cover the most distinct eyebrow shape proportions. Many people's brows fall near the boundary of two types, and the two eyebrows are rarely perfectly identical.

What is the most flattering eyebrow shape for my face?

The ideal eyebrow shape often complements your face shape — softer, curved brows suit angular faces, while brows with a bit more definition can add structure to rounder faces. This tool focuses on identifying your current natural shape; pairing that with your face shape (see our face shape detector) helps guide styling choices.

What is a high arch eyebrow?

A high arch eyebrow — also called an S-shaped brow — has a sharply lifted peak positioned toward the outer third of the brow. It creates a dramatic, sculpted, lifted appearance and is a popular shape in editorial and glam makeup looks.

Is my photo stored or shared?

No. All processing happens entirely in your browser using Google's MediaPipe Face Landmarker. Your photo never leaves your device and is not uploaded to any server.

How accurate is the eyebrow shape detection?

Accuracy depends on photo quality. A clear, well-lit, front-facing photo with your eyebrows fully visible and free of hair or fringe will give the most reliable result. Heavy brow makeup or very sparse brows can occasionally affect the detected outline.

What landmarks are used to measure eyebrows?

The tool uses the upper and lower brow arc landmarks from the MediaPipe 478-point face mesh for each eyebrow. Arch height is measured as the peak height above the baseline relative to brow length; arch position identifies whether the peak sits in the front, middle, or back third; thickness is measured as the vertical gap between the upper and lower brow arcs.

Can eyebrow shape change over time?

Yes — eyebrow shape and density can change with age, hormonal shifts, over-plucking, and grooming habits. Hair follicles can thin over time, and years of shaping can gradually alter the natural arch. Letting brows grow out and using strategic filling techniques can help restore a fuller look.

What eyebrow shape suits a round face?

A higher, more angled arch (S-Shaped or Angled) tends to add definition and visual length to a round face, creating the illusion of more structure. Very flat or fully rounded brows can sometimes emphasise roundness. See our face shapes guide for more face-shape-specific recommendations.

What eyebrow shape suits a square face?

A soft, curved arch (Curved or Rounded) helps balance the strong angles of a square jaw and forehead, softening the overall look. Very sharp, angled brows can sometimes emphasise the squareness of the face.

Can I use this tool for men?

Yes — eyebrow shape analysis applies equally to all genders. The classification types describe proportions, not style preferences, and the styling tips can be adapted for any grooming context, including our dedicated men's eyebrow shapes guide.

What is the difference between Curved and Rounded eyebrows?

Curved (soft arch) eyebrows have a gentle but distinct peak roughly in the middle third of the brow. Rounded eyebrows have a lower, more evenly distributed curve without a clearly defined single peak — the arc rises and falls smoothly across the whole brow length.

Eyebrow Shapes & Types: A Complete Guide

Types of eyebrows, how they're measured, and how to style each shape

The Anatomy of Eyebrow Shape

Eyebrow shape is determined by the underlying brow bone structure, hair growth pattern, and the natural distribution of follicle density along the brow. The arch — the highest point of the brow — is one of the most defining features, and its height and horizontal position (front, middle, or back third) together create the visual impression of each recognised eyebrow shape.

How This Detector Works

This tool uses Google MediaPipe Face Landmarker, trained on millions of diverse faces to place 478 landmarks with sub-pixel accuracy. Eyebrow measurements are computed from the upper and lower brow arc points for each eyebrow. All ratios are normalised against inter-ocular distance for consistency across camera distances. Your photo never leaves your device — all computation runs locally in your browser.

Matching eyebrow shape to face shapePairing your natural eyebrow shape with your face shape is a classic styling principle: softer curved brows tend to balance angular faces, while brows with a more defined arch can add structure to rounder faces. Use our face shapes guide alongside this detector to fine-tune your grooming and makeup choices.
Grooming without over-pluckingUnderstanding your natural eyebrow shape before reaching for tweezers helps you avoid over-plucking and losing your brow's natural line. Strategic filling with pencil, powder, or gel can enhance arch height and definition without any permanent hair removal — a good starting point before considering more permanent shaping or professional threading and waxing.
