Golden ratio face calculator

Mark cheekbone to cheekbone, then hairline to chin. Compare height divided by width with 1.618. Try the sample or open a photo privately in this tab.

Fictional adult sample portrait

Sample portrait · fictional adult · clear anytime

A fictional sample portrait is loading locally. Open a front-facing portrait or reload the fictional example. Mark two cheekbone points for width, then the center of the visible hairline and the bottom of the chin for height. Keyboard: focus the image, move the marker with arrow keys, and press Enter or Space to mark a point.

Measurements

Width: mark two points.

Height: mark two points.

Height ÷ width: waiting for both measurements.

Both lengths are approximate distances between your marks on the original image. Dividing them gives a ratio with no units.

Where to place the four marks

  1. Start with the fictional portrait or choose a front-facing photo with the hairline, chin and both cheek edges visible.
  2. With Face width selected, mark the outer edge of each cheek at cheekbone level. Leave ears, hair and glasses outside the span.
  3. Switch to Face height. Mark the middle of the visible hairline and the bottom of the chin. The calculator shows both straight-line distances in pixels of the original image.

A ratio of 1.50 means the marked height is one and a half times the marked width. Of the numbers on screen, only height divided by width is compared with the golden ratio, the mathematical constant φ, about 1.618.

A worked example with the same portrait

Suppose the cheeks are 150 pixels apart and the hairline is 240 pixels above the chin. The result is 240 ÷ 150 = 1.600. Now mark the hairline six pixels higher. Keeping the same width gives 246 ÷ 150 = 1.640.

Both placements are close to 1.618, one below it and one above it. If the hairline is fuzzy enough for either mark to look reasonable, record the range of readings. Choosing the point that happens to land closest to φ gives a misleading impression of precision.

Golden ratio face calculator questions

Can this calculator tell how attractive a face is?

It returns a geometric observation about the two spans you marked in one photograph. Closeness to 1.618 has no meaning as a beauty score, and the calculator has no attractiveness scale.

Why are the lengths in pixels? Can I convert them to centimeters?

A photo supplies image coordinates. To obtain physical lengths you would also need a reliable scale in the same plane as the face. Dividing height by width cancels the units, so the proportion needs no conversion.

Can I redo the hairline without losing my width measurement?

Select Face height and choose Clear marked points. The two width marks stay in place. Mark the hairline and chin again and compare the new ratio.

What should I do if bangs hide the hairline or the face is turned?

Use a photo that shows the hairline and both cheeks, or practice with the fictional portrait. Turning the head changes the apparent width. Marking the edge of the bangs also shortens the span from hairline to chin.

How can I place the points with a keyboard?

Select width or height, then focus the image. Move the marker with the arrow keys and press Enter or Space at each endpoint. Hold Shift with an arrow key for a larger step.
