Arch Height
Raise the peak of the arch and the eye area opens up, adding vertical to a face that reads short.
Free AI Tool — Grooming Guide
Eyebrow Shaping Guide
An eyebrow shaping guide is an AI tool that maps your facial landmarks to work out your face shape, then matches that shape to the brow arch, angle, and thickness most likely to balance it.
Would a higher arch open your eyes, or would it throw off the rest of your face? Upload a photo and the measurement answers that — not a generic chart that assumes everyone with your face shape wants the same brow.

How Brow Shape Changes a Face
The brow has the upper third of the face almost entirely to itself. The hairline is usually covered by styling or a fringe, which leaves the brow as the one dominant horizontal line up there — change its angle, and the whole upper half of the face reads differently.
Brow Angle
Flatten it out and a long face reads shorter, since a horizontal line cuts against the vertical.
Curve
Round the arch off and it offsets a jaw that leans angular, softening the overall impression.
Human-Written, AI-Measured
The measurement side is automatic. The styling guidance matched to it is written by a person, not generated on the fly.
Three variables are doing all the work here: how high the arch sits, how sharp or soft its angle is, and how thick the brow reads overall. Push any one of them and the face leans longer, softer, or stronger.
The AI handles the reading — the same 68-point landmark map used across every face-shape tool on this site locates your brow bone, temple, and jaw points on your photo. The grooming advice matched to those numbers is convention, not computation, and your own natural growth pattern sets the ceiling on how far any of it can take you.
What Every Arch Looks Like
Curious what a flatter or rounder arch would have looked like on your face instead of the one that came back? The full shape-by-shape reference sits below your result, so you're seeing the reasoning behind the recommendation rather than taking it on faith.
Run the measurement once, and every alternative shape — the ones you got and the ones you didn't — is laid out for comparison in the same place.
Before You
Pick Up Tweezers
Brow hair takes months to grow back, not days, which makes four small setup details worth getting right before the first snip.
Face the Camera Directly
A turned head skews the width readings the entire match depends on.
Clear the Hairline
The jaw and temple points need to be visible; fringe, a hand, or hair falling forward hides them from the model.
Watch the Lighting
Shadow along the jawline is the single most common cause of a wrong shape read.
Treat It as a Starting Point
Personal taste outranks any convention on this page, every time.

Why Brows Punch Above Their Weight
Why does a feature this small carry so much visual weight? Because almost nothing else in the upper third of a face competes with it — the hairline is usually covered, which leaves the brow as the dominant horizontal line in that region, and its angle decides how the whole area reads.
It's also the fastest edit available anywhere on this site, and the slowest one to undo. Brow hair regrows over months, not weeks, which is exactly why one aggressive plucking session can leave a visibly thin brow well into the following season.
What Your Growth Pattern Allows
Picture two people with the identical measured face shape and the identical recommended arch. One reaches it in a single tidy-up session; the other can't — because face shape only describes the target, and a natural growth pattern decides how close any person can get to it.
Sparse tails don't tweeze into a long, elegant taper no matter what the measurement recommends, and a naturally low brow bone caps how high an arch can sit before it starts looking drawn on rather than grown in.
Working with the brow that's already there — tidied rather than reshaped — tends to land better than forcing a growth pattern into a shape it was never going to support. If you're also working out where contour and highlight should sit, the makeup contour guide runs on that same underlying measurement.
About This Tool
Nothing here runs through a licensed third-party API. Ahsan Fayyaz trained the measurement model in-house on real faces and benchmarked it against other face-analysis tools, and it's the same engine used across every style and grooming tool on the site. The result is a styling starting point for entertainment and informational purposes only, not medical, clinical, or professional advice, and it doesn't replace a conversation with a threading technician, esthetician, or dermatologist about what your skin and hair can actually support.

Frequently Asked Questions
It places 68 landmark points on your photo to read your face shape, then matches that shape to a written recommendation covering arch height, angle, and thickness.
No. It hands you a target shape and three named options to describe to a stylist — the actual plucking, threading, or waxing technique is still up to whoever is doing the work.
No. Your photo is processed by the in-house model and deleted from the server right after your result generates. What you see afterward sits only in your browser's cache — refresh the page and it's gone permanently, on both ends.
Two, tracked by browser and IP address.
No. Both daily scans work without one; creating a free account raises the daily limit if you want more.
That's expected sometimes, and it's fine. The guide says outright that personal taste beats any convention on the page — treat the result as a well-reasoned starting point, not an instruction to override what you already know looks good on you.
No, and it isn't meant to. This tool measures your face shape and matches it to a grooming convention; it doesn't assess your skin, your pain tolerance, or technique. Book with a professional for the actual service, and bring the shape name as a reference.
Yes. The measurement runs on facial geometry, not on gender or any single face-shape category, so results cover the full range.
The recommendation still gets generated, but your growth pattern sets a hard limit on how close you can get to it. A sparse tail can't be tweezed into a long, dramatic taper — filling with a pencil or powder can bridge some of the gap, but the underlying growth is the ceiling.
Filters that reshape your jaw or brow area can shift the measurement. Makeup that changes the visible shape of the brow itself — heavy filling that extends past your natural line, for example — can do the same.
More than people expect. Shadow falling along the jawline is the single most common cause of a misread shape, since the model needs a clean edge to measure against.
Yes. Both daily scans can use different photos, and small changes in angle or lighting are often enough to shift the result.
They're three separate measurements that each pull the face in a different direction: arch height affects vertical, angle affects how horizontal or curved the line reads, and thickness affects how strong or soft the brow appears overall.
Yes — the same 68-point landmark map and in-house model power every face-shape and style tool on FaceShapesAI, this one included.
Yes. Both tools measure the same face and work from the same landmark set, so the makeup contour guide is a natural next step if you're planning a fuller look rather than just the brows.
Months, not weeks. That slow regrowth is exactly why the guide recommends treating a result as a starting point rather than a target to force in one sitting.
The measurement is automatic. The styling advice matched to each result is written by a person, drawing on established grooming convention rather than being generated for each result.
Yes — a finished result posts as a styled card, ready for social media, no screenshot required.
No. The model reads geometry — arch position, angle, thickness — not color, so brow color has no bearing on the result.
