Face Shape Calculator
Approximate styling label using local, unvalidated rules. Ratios cannot measure facial angles or attractiveness. Styling suggestions are optional; use the same unit for all measurements.
Site-defined, unvalidated styling rules. Reviewed 2026-09-30. Apply these rules in the listed order; the first match supplies the label. Otherwise there is no single match. All dimensions use the same unit. These are styling conventions, not clinical thresholds.
- length/width ≥ 1.5: |jaw − forehead| ≤ 0.2 × forehead; cheekbone > jaw → Oblong; otherwise → Rectangle
- length/width < 1.2: |length − width| ≤ 0.1 × width → Round; otherwise → Square
- cheekbone/jaw ≥ 1.1; jaw/forehead ≤ 0.9 → Heart
- cheekbone/jaw ≥ 1.1; |jaw − forehead| ≤ 0.1 × forehead → Diamond
- jaw/forehead ≥ 1.1; cheekbone/jaw ≤ 0.9 → Triangle
- |cheekbone − max(jaw, forehead)| ≤ 0.1 × cheekbone → Oval
Approximate styling tool, reviewed 2026-09-30. The local rules and numeric boundaries are unvalidated; they do not establish attractiveness or a universal face taxonomy. Ratios are length/width, jaw/forehead and cheekbone/jaw, using one unit. The rules first check length/width ≥ 1.5 (Oblong or Rectangle), then < 1.2 (Round or Square), then cheekbone/jaw ≥ 1.1 with jaw/forehead ≤ 0.9 (Heart), cheekbone/jaw ≥ 1.1 with jaw and forehead within 10% of forehead (Diamond), jaw/forehead ≥ 1.1 with cheekbone/jaw ≤ 0.9 (Triangle), or cheekbones within 10% of their own width of the larger jaw/forehead measurement (Oval). Long faces use a 20% jaw/forehead tolerance and cheekbones wider than jaw for Oblong; shorter faces use a 10% length/width tolerance for Round. Otherwise the result explicitly reports no single styling match. Ratios alone cannot detect soft or angular contours; descriptions below are style vocabulary, and styling choices are optional.

How to Take Face Measurements
To accurately determine your face shape, follow these measurement guidelines:
- Face Length: Measure from your hairline to the bottom of your chin, keeping the tape straight.
- Face Width: Measure across the widest part of your face, typically across your cheekbones.
- Jaw Width: Measure from one corner of your jaw to the other, across the widest point.
- Forehead Width: Measure across the widest part of your forehead, typically about halfway between your eyebrows and hairline.
- Cheekbone Width: Measure across your cheekbones, from the outer point of one cheekbone to the other.
For best results, use a soft measuring tape and take measurements while looking straight ahead in a mirror.
Different Face Shapes
- Oval: Balanced proportions with a slightly curved jawline. The local Oval branch applies below a length/width ratio of 1.5; it checks cheekbone, jaw and forehead proportions.
- Round: Similar length and width measurements, with soft angles and full cheeks. No sharp angles at the jawline.
- Square: Similar length and width measurements, but with strong, angular features and a prominent jawline.
- Heart: Wider forehead and cheekbones that taper to a narrower, pointed chin. Often features a widow's peak.
- Diamond: Narrow forehead and jawline with prominent, wide cheekbones. Length is typically greater than width.
- Rectangle: Long face with similar measurements for forehead, cheeks, and jawline. Length is notably greater than width.
- Triangle: Wider jawline that gradually narrows towards the forehead. Cheekbones are typically narrower than the jaw.
- Oblong: Similar to rectangle but with more curved edges and prominent cheekbones. Length is significantly greater than width.
Styling Tips
Your face shape can guide your choices in hairstyles, glasses, makeup, and accessories:
- Oval: Most styles work well. Try side-swept bangs and medium-length cuts.
- Round: Create length with layered cuts and avoid chin-length styles. Use angular frames for glasses.
- Square: Soften angles with side-swept styles and layers. Choose oval or round glasses frames.
- Heart: Balance width with chin-length bobs or long layers. Avoid heavy bangs.
- Diamond: Add width at forehead and jaw with side-swept bangs and chin-length styles.
- Rectangle: Create width with layers and waves. Avoid very long, straight styles.
Common Features
Each face shape typically exhibits certain characteristics:
- Prominent Cheekbones: Common in diamond and oval shapes
- Strong Jaw: Characteristic of square and triangle shapes
- Soft Angles: Typical in round and oval shapes
- Wide Forehead: Common in heart shapes
- Balanced Proportions: Characteristic of oval shapes
- Angular Features: Common in diamond and square shapes
Frequently Asked Questions
Can face shape change over time?
The result can change if the entered measurements change. A label is an approximate styling description of these inputs.
Why is knowing your face shape important?
Understanding your face shape helps you choose the most flattering hairstyles, makeup techniques, glasses frames, and accessories. It can also guide contouring and highlighting techniques.
What if my face doesn't fit exactly into one category?
Many people have combination face shapes that share characteristics of multiple categories. Focus on the most prominent features when making styling choices.
