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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 main different types of lips — also called different kinds of lips — are Full, Thin, Wide, Heart-shaped, Round, Top-heavy, and Bottom-heavy. Full lips have generous volume in both the upper and lower lip. Thin lips have a refined, slim profile. Wide lips have a notably generous corner-to-corner span. Heart-shaped lips feature a pronounced cupid's bow M-curve. Round lips have gently curved, even edges. Top-heavy lips have a notably fuller upper lip; bottom-heavy lips have a notably fuller lower lip. These seven types cover the most distinct lip proportions found across different people, though many lips fall near the boundary of two types.

The rarest lip shape is generally considered to be a naturally perfect heart-shaped lip — one with a very pronounced, symmetrical cupid's bow M-curve, equal left-right arch peaks, and a well-defined centre dip. Full lips with a strong cupid's bow and balanced upper-to-lower proportion are also relatively uncommon. Thin lips with an extremely refined, symmetrical outline and wide lips with a notably generous span are less common than round or moderately full lip shapes. Rarity varies by ethnicity and genetics; no single lip shape is universally rare across all populations.

While there is no scientific evidence that lip shape determines personality, the cultural and aesthetic associations are well established. Heart-shaped lips are classically associated with romanticism and expressiveness. Full lips are linked to warmth and approachability. Thin lips are associated with precision and elegance. Wide lips suggest expressiveness and openness. Top-heavy lips are often seen as dramatic and sculptural. Bottom-heavy lips carry a natural, effortless look. These are aesthetic frameworks, not personality predictors — what your lip shape genuinely says about you is your unique genetic anatomy.

When the top lip is noticeably bigger or fuller than the bottom lip, this is classified as a Top-heavy lip shape. The upper lip has greater vertical height at its centre than the lower lip. This creates a sculptural, dramatic appearance. It differs from a heart-shaped lip in that the defining feature is volume and height, not the definition of the cupid's bow. Many people seek lip augmentation shapes that balance the upper and lower lip to achieve a more proportional pout — a common goal in lip filler procedures.

Lip filler shapes and lip augmentation shapes refer to the target proportions that can be achieved through lip filler injections or other cosmetic procedures. Common goals include adding overall fullness (achieving a fuller lip shape), enhancing the cupid's bow definition (creating a heart-shaped appearance), balancing a top-heavy or bottom-heavy asymmetry, or adding width. Understanding your natural lip shape first — using a tool like this analyzer — helps you and your practitioner identify which augmentation shape would complement your face proportions. This tool is not a clinical planning tool; always consult a qualified aesthetic practitioner for lip augmentation advice.

Full lips are lips with generous vertical volume in both the upper and lower lip — a high upper-to-width ratio and a well-padded lower lip. Clinically, full lips are often defined as having a 1:1.6 upper-to-lower ratio (some standards use 1:2). Aesthetically, full lips appear plump, rounded, and three-dimensional. They are one of the most sought-after lip shapes in cosmetic augmentation. This tool measures fullness as a ratio of total lip height to lip width — lips scoring high on this metric are classified as Full.

Naturally heart shaped lips are determined by genetics — specifically the depth and symmetry of the cupid's bow M-curve at the top of the upper lip. You cannot permanently alter your natural lip anatomy without cosmetic procedures, but makeup can visually create the appearance: use a nude liner to lightly fill in either side of the centre bow dip, then re-draw the arch peaks fractionally higher before filling with your chosen shade. Lip filler for heart shaped lips uses precise hyaluronic acid placement at the bow peaks to enhance definition, or adds lower lip volume to balance a prominent upper bow. Facial exercises are widely promoted online for this purpose, but there is no clinical evidence that any exercise can meaningfully alter cupid's bow shape or prominence.

Downturned lips occur when the outer corners of the mouth — the oral commissures — point slightly downward in a neutral expression, giving the appearance of a subtle frown even at rest. This is a common anatomical variant caused by the relative pull of the depressor anguli oris muscles at the mouth corners, and it can become more pronounced with age as skin elasticity decreases. Cosmetically, downturned lips filler placed at the oral commissure can subtly lift the corners; botox for downturned mouth (injected into the depressor anguli oris) relaxes the downward pull; and a corner mouth lift (commissuroplasty) is the most permanent surgical option. Non-invasively, drawing a lip liner very slightly above the natural outer corner line can visually soften the droop. Always consult a qualified aesthetic practitioner before any procedure.

Bow shaped lips — also written bow-shaped lips — are defined by a prominent, well-defined cupid's bow on the upper lip. The term overlaps with heart shaped lips, though bow lips shape typically refers to lips where the defined arch is the primary feature rather than extreme peak height. A cupid's bow lip shape (or cupid bow lip shape) refers specifically to the double-peak M-curve at the top of the upper lip, named after the bow of the Roman god of love. Bow shaped lips are considered a classic beauty feature across many aesthetic traditions. Precise liner tracing at the arch peaks and a lighter gloss or shade at the centre bow dip enhance the natural definition beautifully.

Wide lips have a notably generous corner-to-corner horizontal span relative to the overall width of the face. The defining feature is horizontal breadth rather than vertical volume — a wide lips shape can be slim or full in height. Wide lips create a striking, expressive appearance. Those who want wider lips can use a lip liner extended subtly at the outer corners to increase the perceived span; those who prefer to minimise width can apply slightly deeper shades at the outer edges while keeping the centre lighter. Warm rose and berry shades in medium depth are especially flattering on wide lips.

Getting bigger lips naturally without procedures relies on makeup technique and skincare: (1) Apply a plumping gloss at the centre of the lower lip to create the visual impression of depth and volume; (2) Overline very subtly — trace a lip pencil 1–2mm above the natural vermilion border; (3) Avoid very dark matte shades, which absorb light and make lips appear smaller; (4) Place a small highlight just above the cupid's bow to draw the eye upward; (5) Exfoliate and hydrate regularly — smooth lips appear fuller than dry, flaky ones. Lip enhancement naturally also benefits from maintaining overall skin hydration. For thin lips augmentation, hyaluronic acid filler remains the most effective non-surgical clinical option, producing temporary results (typically 6–18 months) that are reversible.

Round lips — also called rounded lips — have gently curved outer edges, soft corners, and relatively even fullness from corner to corner. The upper lip has a mild, soft cupid's bow without the sharp arch peaks of heart shaped lips, giving the full lip outline a smooth, uniform arc. The natural rounding of both lips creates a youthful, approachable, and harmonious appearance. Round lips are one of the most common lip shapes globally. They suit warm nude shades, dusty mauves, and a centre-focused gloss highlight for a balanced, polished look.

A fuller lower lip — where the lower lip is noticeably more voluminous than the upper — is classified as a bottom-heavy lip shape and creates a natural, effortless pout. A fuller upper lip — where the upper lip is more voluminous — is classified as top-heavy, giving a sculptural, dramatic appearance. A thin upper lip full bottom lip combination is one of the most common presentations of the bottom-heavy type. In cosmetic practice, balancing a fuller lower lip with added upper lip volume, or complementing a full upper lip with lower lip filler, are among the most common lip augmentation goals. Both profiles are distinctive and beautiful in their own right.
