Lip Shape Chart: Identify Your Lip Type in 3 Steps

Compare the outline, width, fullness, and cupid's bow of relaxed lips without forcing every feature into one perfect label.

Quick answer: Start with three cues: whether the mouth is wide or compact, whether the upper or lower lip carries more volume, and whether the cupid's bow is sharp, soft, or nearly flat. Match those cues to the chart, then verify with a straight-on, relaxed photo. Many people have a mixed result, such as wide and full or oval with a defined cupid's bow.

Quick Lip Shape Chart

Use the dominant cue in each row as a starting point. The final check prevents common mix-ups between labels that share one feature.

ShapeDominant visual cueFinal check
Cupid bowA clear M-shaped peak in the upper lipThe center definition is stronger than the overall heart taper
Heart-shapedDefined upper center with a fuller middle and narrower cornersThe entire outline, not only the bow, suggests a heart
RoundCompact width with a soft, curved outlineVertical fullness is noticeable and corners do not extend far
OvalBalanced fullness with a smooth elongated curveThe outline is softer and longer than a round profile
WideCorners extend horizontally across the faceWidth remains the main feature even if the lips are full or thin
ThinLow vertical height in one or both lipsJudge relaxed lips, not compressed or pressed lips
FullStrong volume in both upper and lower lipsFullness is visible across most of the mouth, not only the center
AsymmetricOne side or one peak differs visibly from the otherThe difference remains across multiple neutral photos

How to Identify Your Lip Shape with Three Measurements

You do not need a ruler or a mathematically perfect face. The goal is to compare visible relationships while your lips are relaxed.

Check each cue separately before choosing a label. This is more reliable than deciding from the cupid's bow alone.

Use consistent reference lines for width, vertical fullness, and cupid's bow depth.
  1. Width: Compare the mouth width with the lower nose and the center of the face. A clearly extended horizontal line suggests wide lips; a compact line supports round or heart-shaped profiles.
  2. Upper-to-lower balance: Notice whether the lower lip is much fuller, both lips are similarly full, or the overall vertical height is slim. This separates full, oval, and thin profiles.
  3. Cupid's bow and corners: A sharp M-shaped center supports cupid bow or heart-shaped lips. A soft curve supports oval or round lips. Also note whether the corners remain level, lift, or turn slightly down.

Use a Neutral Photo Before You Decide

Camera angle, expression, liner, and gloss can change the outline enough to produce a different result. Use one neutral image as the reference and other images only as secondary checks.

Angled, straight-on, and smiling lip photos compared side by side
The centered neutral photo is the most useful reference; angles and smiles can change the apparent shape.
  • Face the camera: Keep the lens near mouth height and avoid a high or low angle.
  • Relax your mouth: Do not smile, pout, press the lips together, or pull the corners outward.
  • Use even light: Front light shows the border more clearly than strong side light or a beauty filter.
  • Remove outline-changing makeup: Heavy liner and overlining are useful styling tools, but they should not be used for the first classification photo.
  • Check more than one photo: If the result changes, prioritize the clearest straight-on image and record the second feature as a modifier.

What If Two Lip Shapes Match?

Lip labels describe visible patterns, not fixed biological categories. A person can have a defined cupid's bow, wide corners, and full vertical volume at the same time. In that case, choose one primary label for the dominant outline and one modifier for proportion.

Small left-right differences are also normal. Classify the overall silhouette instead of comparing each side as if it must be identical. If swelling, injury, or a sudden change affects the shape, wait until it resolves or seek appropriate professional advice rather than using a beauty chart.

Use a two-part result

Examples such as “wide, full lips” or “oval lips with a defined cupid's bow” are often more accurate and useful than forcing one label.

Choose the Guide That Matches Your Main Cue

After the chart gives you a likely profile, compare it with a dedicated guide or use the photo detector for a second opinion.

Lip Shape Chart FAQ

Use a straight-on relaxed photo and compare width, upper-to-lower fullness, cupid's bow depth, and the corners. Select the dominant outline first, then add a modifier such as full, thin, wide, or asymmetric.

Yes. The labels overlap because they describe different features. A result such as wide and full, or oval with a pronounced cupid's bow, can be more precise than one label.

No. Smiling stretches the corners and can make the lips look wider and thinner. Use a relaxed mouth for classification, then use smiling photos only to understand how the shape changes with expression.

It can. Overlining, concealer, gloss highlights, and dark corner shading alter the visible border. Make the first comparison without outline-changing makeup.

Small differences between the two sides are common. Use several neutral photos before calling the shape asymmetric, because camera angle and expression often exaggerate minor differences.

They are useful in different ways. A chart makes the visual criteria transparent, while an AI result offers a fast second opinion. Photo quality and natural variation limit both, so compare the reasoning rather than treating either result as a medical measurement.
