How the Lip Shape Analyzer Works
Four steps from photo to personalized styling tips — all processed locally on your device.
Upload or take a photo
Upload a clear, front-facing photo or use your device camera directly in the browser. A relaxed or neutral expression gives the best lip measurement.
AI maps 478 facial landmarks
MediaPipe Face Landmarker runs entirely in your browser and locates 478 precise points — including the full outer and inner lip contour — without uploading any data.
Five lip measurements are computed
The analyzer measures lip width, upper and lower lip heights, fullness ratio, and cupid's bow definition — all relative to your face proportions.
Your lip shape is classified
Based on those measurements, your lips are classified into one of seven types: Full, Thin, Wide, Heart-shaped, Round, Top-heavy, or Bottom-heavy.
Which Lip Shape Are You?
Seven distinct types classified by width, fullness, upper-to-lower proportion, and cupid's bow definition.
Full
Generous volume in both upper and lower lip with a balanced, plump proportion.
- ·Bold saturated shades
- ·Gloss or satin finish
- ·Ombre shading adds dimension
Thin
Refined, slim lips with clean lines — a classic, elegant canvas.
- ·Warm coral and rose shades
- ·Plumping gloss at the centre
- ·Slightly overdrawn liner
Wide
Notably generous corner-to-corner span — striking and expressive.
- ·Rich, saturated colours
- ·Bold matte finish
- ·Avoid horizontal shimmer at corners
Heart-shaped
A pronounced cupid's bow M-curve at the top — classically sculpted.
- ·Deep roses and burgundies
- ·Highlight the bow dip
- ·Precise liner at the arch peaks
Round
Gently curved, even shape with soft outer corners and a youthful look.
- ·Warm nudes and dusty mauves
- ·Glossy centre highlight
- ·Monochromatic beauty looks
Top-heavy
Upper lip notably fuller than the lower — sculptural and dramatic.
- ·Gloss on lower lip
- ·Slightly deeper upper shade
- ·Warm terracotta tones
Bottom-heavy
Lower lip notably fuller — a natural, effortless pout.
- ·Classic reds and deep berries
- ·Lighter upper lip shade
- ·Define upper lip with liner
How to Photograph Your Lips
A good photo makes a significant difference. Follow these tips for the most accurate lip shape result.
Face the camera directly
Look straight ahead — chin level, not tilted up or down. Even a small angle changes the measured proportions.
Relaxed or neutral expression
Keep lips gently closed or very slightly parted. A big smile pulls the corners wide and skews the width measurement.
Even, natural lighting
Soft daylight from in front is ideal. Side lighting or heavy shadows across the lower face can affect the detected lip contour.
Minimal lip makeup
For the most accurate measurement of your natural lip shape, photograph your lips with little or no lipstick and no heavy liner.
Single face in frame
The analyzer works best with one person clearly visible. Make sure no other faces are partially in the frame.
Hair away from the face
Hair falling over the lower face can occasionally obscure jaw and chin landmarks used for normalisation.
Unexpected result? Retake the photo in natural light, facing the camera directly with a relaxed expression and minimal lip makeup. Small changes in angle or expression can shift the classification.

Frequently Asked Questions
Everything you need to know about lip shapes and how the analyzer works.
What is a lip shape analyzer?
A lip shape analyzer uses AI facial landmark detection to measure the proportions of your lips from a photo — including width, height, upper-to-lower ratio, and cupid's bow definition — and classifies them into a named lip shape type. The classification is paired with personalized lipstick and makeup tips.
How many lip shapes are there?
This tool classifies lips into seven types: Full, Thin, Wide, Heart-shaped, Round, Top-heavy, and Bottom-heavy. These cover the most distinct lip proportions. Many people's lips fall near the boundary of two types — the dominant proportion determines the classification.
What is the most common lip shape?
Round and Full are among the most common lip shapes globally, followed by Heart-shaped. Thin and Wide shapes represent a smaller proportion of people. All shapes are equally beautiful and work with every makeup style when you know the right techniques.
What is a heart-shaped lip?
Heart-shaped lips are defined by a pronounced cupid's bow — the M-shaped curve at the top of the upper lip. The two arch peaks are higher than the centre dip, creating a sculpted, romantic shape. This is one of the most prized lip shapes in classic beauty.
What is a cupid's bow?
A cupid's bow is the M-shaped curve at the top of the upper lip. It's named for the bow of Cupid, the Roman god of love. A well-defined bow has two prominent arch peaks that rise above the centre dip. The definition of the bow is one of the key measurements in this tool.
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 lip shape detection?
Accuracy depends on photo quality. A clear, well-lit, front-facing photo with a relaxed or neutral lip expression will give the most reliable result. Heavy lip liner or dark lipstick can sometimes alter the perceived outer contour. For best accuracy, photograph your natural lips in even light.
What landmarks are used to measure lips?
The tool uses the full outer lip contour landmarks from the MediaPipe 478-point face mesh, including the mouth corners, cupid's bow arch peaks, the outer upper lip centre, and the inner and outer lower lip points. Width, height, and bow definition are computed from these.
Can lip shape change over time?
Yes — lip shape and volume change with age. Lips typically lose volume and definition gradually over time, particularly after the mid-30s, due to collagen loss, reduced hyaluronic acid, and thinning of the vermilion border (the outer edge). Lip contouring with liner can compensate for these changes.
What lipstick finish suits thin lips?
Glossy and satin finishes are most flattering for thin lips — they reflect light and create the visual impression of more volume. Matte formulas tend to emphasise thinness. A plumping gloss with a subtle shimmer at the centre of the lower lip is especially effective.
What lipstick finish suits full lips?
Full lips suit virtually any finish. Gloss and satin amplify the natural volume, while matte provides a bold, editorial look. Bold saturated colours — berry, deep plum, classic red — are particularly striking on full lips.
What is the difference between full and round lips?
Full lips have generous volume in both the upper and lower lip, with a notable height relative to width. Round lips have gently curved edges and a soft, even shape, but may have less pronounced vertical volume. The primary distinction is fullness (height/width ratio) vs overall curvature and arch definition.
How do I photograph my lips for the best result?
Take a clear, front-facing photo in even, natural light. Use a relaxed or slightly-parted neutral expression — avoid a big smile or strong expression. Remove heavy lip liner and very dark lipstick if possible. The camera should be level with your face, not angled up or down.
What is top-heavy versus bottom-heavy lips?
Top-heavy lips have a notably fuller upper lip relative to the lower lip. Bottom-heavy lips have a notably fuller lower lip — this creates a natural pouty appearance. The upper/lower balance is measured by comparing the heights of the two lips at their centres.
Can I use this tool for men?
Yes — lip shape analysis applies equally to all genders. The classification types (Full, Thin, Wide, etc.) describe proportions, not style preferences. The styling tips are written for a broad audience and can be adapted for any makeup or grooming context.
Does lip contouring change my lip shape?
Lip contouring with liner and colour can visually alter the perceived shape significantly. Overlining the upper lip defines the cupid's bow and adds height; applying gloss or lighter shades in the centre adds visual fullness; deeper shades at the edges narrow a wide shape. This tool measures your natural anatomy, not the made-up appearance.
Can I use this to plan lip filler?
This tool can help you understand your natural lip proportions, but it is not a clinical measurement tool and should not be used as the basis for cosmetic procedure planning. Consult a qualified aesthetic practitioner for any clinical decisions about lip augmentation.
The Science of Lip Shape
Lip shape is determined primarily by genetics — the thickness of the orbicularis oris muscle, the amount of subcutaneous fat, the height of the vermilion border (the edge where lip skin meets facial skin), and the structure of the underlying bone all contribute to the unique profile of every person's lips. The cupid's bow — the M-shaped curve at the top of the upper lip — is one of the most genetically variable features of the lower face.
This tool uses Google MediaPipe's Face Landmarker, a machine-learning model trained on millions of diverse faces to place 478 landmark points with sub-pixel accuracy. The lip measurements are computed from a specific subset of these landmarks: the outer and inner lip contour points, the mouth corners, the cupid's bow arch peaks, and the centre points of both lips. All ratios are normalised against the inter-ocular distance to make the results comparable across different camera distances and face sizes.
All computation is local — your photo never leaves your device. No image data is transmitted to any server. The result you see is generated entirely within your browser tab and discarded when you close it.
