Find your face shape for glasses

Stays on your device

Add a front photo or selfie

JPG, PNG or WebP · drop it here or press Ctrl+V · HEIC only where your browser opens it

For a reliable result

  • Camera at eye level, about an arm’s length away
  • Hair back, so forehead and jaw are visible
  • No glasses, a relaxed face, looking straight ahead
  • Even light from the front, no strong shadows

Your photo never leaves this device. The face model (about 18 MB) loads from this website when you add a photo.

No photo? Enter four measurements

Use a mirror and a ruler held flat, or a printed front photo. Measure straight across, not around the curve of your face.

  1. Forehead
  2. Cheekbones
  3. Jawline
  4. Face length

The colored lines show where to measure. Hold the ruler level and read it with your head straight.

Unit

Across the widest part of the forehead, about halfway between eyebrows and hairline.

Across the widest part of the face at the cheekbones, below the outer corners of the eyes.

Straight across from one jaw corner, below the ears, to the other.

From the middle of the hairline down to the tip of the chin.

Jaw and chin

Your photo stays private. It is measured in your browser and never uploaded or stored. The face model (about 18 MB) comes from this website the first time you add a photo.

A face shape is an estimate. Pose, lens and light change the numbers a little, and many faces sit between two shapes. The tool measures proportions only: it does not recognize who you are.

How the glasses check works

  1. Add a front photo

    Without your glasses, hair back, looking straight into the camera. Or enter four measurements in the manual form.

  2. Check the hairline and points

    Move the dashed hairline if it does not sit where your forehead meets your hair, and drag any colored point that is off the edge of your face. The face shape updates as you move them.

  3. Read the glasses ideas

    The Glasses tab opens first: frame shapes for your face with a small drawing of each, and the frame width that matches your face.

What is my face shape for glasses? Frames by result

Face shapeFrames to try
OvalRectangular or geometric, as wide as the cheekbones or a little wider
RoundRectangular or square frames with clear corners
SquareRound or oval frames with thin rims
HeartBottom-heavy, oval, rimless or light aviators
DiamondOval, cat-eye, rimless or browline
Oblong (long)Oversized or deep frames
Triangle (pear)Browline and cat-eye frames

The guide to glasses for every face shape explains why these shapes work and what else to look at.

Frame width versus face width

Shape is only half of it: frames should be about as wide as your face at the cheekbones. Frames that are much narrower make the face look wider; frames that stick out past the face look heavy.

With a photo, the tool estimates your face width from the size of your iris, which is about 11.7 mm wide in most adults, and turns it into a range of frame widths in millimeters. Treat it as a starting point: it can be off by about a centimeter. The manual form uses the cheekbone width you measured.

Shops call it frame width or total width. The three numbers printed inside the temple of your glasses, such as 52-18-140, are the lens width, the bridge and the temple length; two lens widths plus the bridge plus a few millimeters for the frame edges come close to the frame width.

Trying frames on: what to check besides the shape

  • Eyebrows: the top of the frame should follow your brows, not cut across them.
  • Bridge: the frame should sit on your nose without sliding or pinching.
  • Eyes in the middle: your pupils should sit near the middle of each lens.
  • Prescription: strong or progressive lenses need enough lens height; ask your optician before choosing very slim frames.

Frequently asked questions

What is my face shape for glasses if I am between two shapes?

Read the frame ideas for both shapes and choose frames that appear in both lists, or that suit the shape with the higher score. Many faces between oval and another shape can wear a wide range of frames.

How do I know my frame width?

Look at the frame width the tool suggests, or hold a ruler across your current glasses from hinge to hinge on the outside. Shops list this number as frame width or total width.

Do I need to take my glasses off for the photo?

Yes, a photo without glasses works best. Frames cover the temples and the eye area, and the model may place the points less reliably.

Is the face shape detector for glasses free?

Yes, it is free online with no account and no limit. The photo is measured in your browser and is not uploaded.
