Does nose width need to match the gap between my eyes?

That's the classic rule, but most faces are a little wider or narrower. It isn't a requirement your face needs to meet.

Does this ratio tell me my nose width in centimetres?

No. It compares widths rather than giving an absolute measurement in centimetres. It also doesn't tell you an average nose width.

Does a wider ratio mean my nose is too wide?

It means nostril width is greater relative to the inner-corner distance in that measurement. It doesn't establish that your nose needs changing.

What the ratio compares

This nostril-width ratio uses the distance across your nostrils and the gap between your inner eye corners. It doesn't compare your nose with the full width of your face.

The reference distance matters. A ratio using another part of your face answers a different question, even if its label sounds similar. See eye spacing for the related term, or browse the glossary to compare definitions.

How to read a selfie measurement

Divide nostril width by the distance between the inner eye corners, using the same image for both measurements. Check that the marked points match those named in the definition. Otherwise, you're calculating a different proportion.

Why the classic rule has limits

The classic rule treats nostril width and inner-corner distance as matching widths. Most faces are a little wider or narrower, so a mismatch alone isn't a reason to change your nose.

The evidence status is mixed evidence. Being able to calculate a nose-to-eye-spacing ratio doesn't establish an ideal result. Don't use this proportion as a substitute for judging facial harmony across your whole face.

What to do with your result

Use the result to describe the relationship between the measured widths. If you're comparing readings, check that each uses the same definition before deciding your nose looks wider or narrower.

The common mistake is treating one number from one photo as a fixed fact about your face. Keep the image and its marked points alongside the result. A ratio without that context gives you less information than it appears to.
