1. Set up a straight view
Stand in front of a mirror with soft, even light. Hold your head level, relax your mouth and clip hair away from your temples. Ignore your ears and the silhouette of your hairstyle. For a photo, keep the camera level with your eyes and step back instead of holding a wide-angle lens close to your face.
If a shadow hides the lower jaw or your hair covers one temple, change the light or the framing before deciding. Comparing two clear views is more useful than trying to read a precise ratio from one distorted photo.
2. Make four simple comparisons
- Visible length: Look from the top of the visible forehead area to the bottom of the chin. Does this look distinctly longer than the widest cheek span, or fairly close to it?
- Cheekbones: Find the widest horizontal span across the outer cheeks. Compare it with the spans above and below, rather than using a highlight or shadow as the edge.
- Temples: Check whether the upper face is almost as wide as the cheeks or noticeably narrower. A widow’s peak or the height of the hairline does not answer this question.
- Jaw: Check how far the width carries down the sides, then look at how the lower outline turns in toward the chin. A pointed chin and an angular jaw are different observations.
If you want to use a ruler, mark the spans on a copy of the same photo and compare them in the same units. You are looking at relative widths, not physical measurements of your face. The facial proportions guide shows what the ratios mean.
3. Match the pattern you see
- Oval face shape: Moderately longer than wide, with a gradual taper below the cheekbones.
- Round face shape: Length and width look close, with a smooth turn from cheeks to chin.
- Square face shape: The jaw stays broad below the cheeks and turns more clearly toward the chin.
- Heart face shape: The upper face stays broad while the lower face narrows toward the chin.
- Diamond face shape: The cheeks are distinctly wider than both the temples and the jaw.
- Oblong face shape: Visible length stands out relative to cheek width, even with the head level.
Start with the strongest clue. If length and width look close, compare round and square by looking at the jaw. If the jaw narrows below a broad upper face, compare heart and diamond by looking at the temples. If the face looks long, compare oval and oblong by looking at how strongly length stands out and how early the sides taper.
4. Break a tie with a second view
Suppose the jaw narrows and the cheeks look widest. If your temples are close in width to the cheeks, heart is a sensible first comparison. If your temples narrow clearly, try diamond. If hair hides the temples in one photo, retake it before deciding. Use the same process for other close pairs: find the feature that separates them, then check it in a clear view.
It is normal to keep two possibilities. The categories are useful for describing an outline and choosing styles to try. You can pick hair or glasses ideas based on the feature you want to emphasize without settling on a single label.

The free tool draws the length, cheek and jaw lines on your photo, compares six outlines and shows the two closest matches. The analysis runs in your browser. Use the result to see why two shapes may be close and open either guide for more context.
