01 / MEASURE THE RELATIONSHIPS
How a face shape detector works
A useful face shape detector compares proportions rather than searching for one perfect outline. It considers the widest area of the face, the way the jaw narrows or stays broad and the relationship between facial width and length.
Most people combine traits from more than one familiar category. A face can have an oval length, a softly squared jaw and prominent cheekbones at the same time. Solvi keeps those mixed signals visible instead of forcing every face into a single rigid label.
Forehead
Compare its widest points with the cheekbones and jaw, without using the hairline alone as the boundary.
Cheekbones
Look at the width through the upper cheeks and how quickly the face tapers below them.
Jaw
Note whether the lower face appears rounded, tapered, angular or similar in width to the forehead.
Length
Compare the vertical distance from upper forehead to chin with the widest horizontal measurement.
02 / REMOVE DISTORTION
Take a photo that preserves your proportions
A close wide-angle selfie can enlarge the center of the face and make the sides appear narrower. Camera height, head tilt and hairstyle can also change the outline. A guided capture reduces those effects before any proportions are compared.
Step back
Use the rear camera or place the phone farther away, then crop rather than holding it close to your nose.
Stay level
Keep the camera at eye height and hold your head upright without raising the chin.
Clear the outline
Pull hair away from the sides of the face while keeping the forehead and jaw visible.
Use neutral light
Soft frontal light makes the real contour easier to see than a hard side light or beauty filter.
03 / COMMON PATTERNS
Face shape categories are starting points
Traditional categories offer useful shorthand, but the borders between them are not exact. The most helpful result describes the dominant proportions and the secondary traits that make your face individual.
Oval
The face reads longer than wide, with a gently curved jaw and balanced tapering.
Round
Width and length are closer, with soft transitions through the cheeks and jaw.
Square
Forehead, cheekbone and jaw widths are relatively close, with a more angular lower face.
Heart or tapered
The upper face appears broader and narrows more noticeably toward the chin.
Oblong
Facial length is more pronounced while the side widths remain relatively consistent.
Diamond
Cheekbones read as the widest point, with narrower forehead and jaw proportions.
04 / USE THE RESULT
What face shape can help you understand
Face shape can add context when you compare hairstyles, eyewear, makeup placement or facial hair. It is most useful when treated as one part of the full face rather than a rule about what you should wear.
Solvi combines shape with symmetry, feature scale and visible skin signals. That broader view helps explain why the same style can read differently on two people who share the same basic face shape category.
QUESTIONS / ANSWERED
What people ask before they start
01Can a face shape detector identify mixed face shapes?+
Yes. A result can describe a dominant pattern and secondary traits, such as an oval face with a more angular jaw, instead of forcing one label.
02Why does my face shape look different in selfies?+
Close camera distance, wide-angle lenses, head tilt and lighting can distort facial proportions. A level camera placed farther away usually gives a more representative image.
03Does weight change face shape?+
Soft tissue distribution can change the visible outline, while the underlying relationship between forehead, cheekbones and jaw may remain similar. Age, expression and hairstyle can also affect how the shape reads.
04What do I receive after the face analysis?+
Solvi summarizes your dominant proportion pattern and shows how it works with other visible facial signals in your personalized analysis.
