What is the ideal nose width?

Nose width has a big influence on facial balance because the nose sits right in the centre of the face. The classic guideline, used by artists and facial plastic surgeons, is that the width of the nose at the nostrils should be about the same as the distance between the eyes — the gap between the inner eye corners. That's part of the "rule of fifths", which divides the face across the eyes into five equal parts.

This free nose width ratio calculator checks your nose against that guideline and against the width of your face, and tells you whether your nose is narrow, slim, balanced, broad or wide.

How the nose ratio calculator works

The calculator runs Google's MediaPipe Face Mesh in your browser (your photo isn't uploaded) and places landmarks on the outer edges of your nostrils, the inner corners of your eyes and your cheekbones. It measures two ratios:

RatioFormulaTarget
Nose-to-faceNose width ÷ face width at the cheekbonesAbout 0.275
Nose-to-eyeNose width ÷ distance between the inner eye cornersAbout 1.0

Each ratio is scored by how close it is to its target, and the two are averaged into a score out of 100.

ScoreResult

Your nose type is based on the nose-to-face ratio:

Why nose width varies so much

Nose shape varies a great deal between people and populations. Research on human evolution suggests climate played a role — narrower noses are more common in populations from colder, drier climates and wider noses in warmer, more humid ones. That means a nose that's "broad" by a single numerical target can be completely typical, and very attractive, for someone's background. The targets here are general proportions, not a single correct nose.

It's also worth knowing that the guideline is about balance: a broader nose can look perfectly in proportion on a face with wider-set eyes or a wider face, which is exactly why this calculator compares your nose with both.

Close-up selfies make your nose look wider

If your result says your nose is broad and you don't think it is, check how the photo was taken. A 2018 study in JAMA Facial Plastic Surgery found that selfies taken about 30 cm from the face make the nose look around 30% wider than photos taken from 1.5 m away. Use the rear camera from arm's length or further, or ask someone to take the photo.

Can you change how wide your nose looks?

  • Photo technique is the biggest factor in photos — distance and angle change apparent nose width a lot.
  • Contouring makeup along the sides of the nose can make it look slimmer.
  • Rhinoplasty can narrow the nostrils (alar base reduction) or the bridge. It's a major surgery with a long recovery, so it should be done by a board-certified facial plastic surgeon.
  • Non-surgical "nose jobs" with filler can change the profile but can't make the nose narrower.

Nose exercises and nose-slimming clips don't change nose width.

Tips for an accurate result

  1. Stand back from the camera — at least arm's length.
  2. Face the camera directly so both nostrils are equally visible.
  3. Keep a neutral face. Smiling flares the nostrils.
  4. Use even front lighting so the edges of the nostrils are clear.

Frequently asked questions

What is the ideal nose width?

The classic guideline is that the nose should be about as wide at the nostrils as the distance between the inner corners of the eyes. This calculator also targets a nose about 27.5% of the face's width at the cheekbones.

How do I know if my nose is too wide?

Compare its width with the gap between your eyes. If your nose is noticeably wider than that gap, it's broader than the classic guideline. This calculator measures both from a photo and classifies your nose from narrow to wide.

Why does my nose look bigger in selfies?

Because close-up cameras distort the centre of the face. A 2018 study found selfies taken about 30 cm away make the nose look around 30% wider than photos taken from 1.5 m away.

Can you make your nose narrower without surgery?

Not permanently. Contouring makeup can make it look slimmer, and taking photos from further away removes distortion, but exercises and clips don't change nose width.

Is the nose ratio calculator free?

Yes. It's free, needs no signup, and analyses your photo in your browser.
