Sizes
and shapes

Finding the right glasses is a matter of proportion. In four steps, you'll understand your size, learn to read the numbers printed on the temples, and discover the shapes that best harmonize with your face.

01

Measure your face

2 minutes · only a card needed
85,6 mm
STEP 1

Grab a card

A credit card or health insurance card: they all have the same standard width, so they work as a ruler.

STEP 2

Hold it against the mirror

Standing in front of the mirror, hold the card vertically and align its inner edge with the center of your iris.

A B C
STEP 3

See where it ends

The point where the opposite edge of the card falls on your eye gives you the answer: A, B, or C.

02

Find your size

Select your result
YOUR RESULT A — Narrow fit

Look for smaller calibres, between 47 and 49 mm lens. A frame that is too wide will slide down your nose and protrude beyond your temples.

YOUR RESULT B — Medium fit

You're in the most common size: lenses between 50 and 54 mm. Almost all shapes work, choose based on style.

See frames →
YOUR RESULT C — Wide fit

Aim for lenses 56 mm and up, and temples 145 mm. Small frames compress the temples and pinch behind the ear.

Choose the shape

Golden rule: contrast, not repetition

Oval face

Balanced proportions: almost anything works, stay within the width of the face.
