Measure it properly, then choose

Most style tools guess. These measure. Every tool on Lookmetry runs its analysis inside your browser, shows you the numbers it worked from, and tells you how confident it is.

Nothing you photograph is uploaded, stored or shared. There is no account.

Measure your pupillary distance

Eyewear and vision

Measure what a retailer asks for, understand what an optician wrote down, and work out whether a frame fits before you buy it.

Pupillary distance

The millimetre figure online retailers ask for and your prescription probably omits. Measured from your own iris, averaged over sixty frames, with a confidence range.
Frame size finder

Face width and PD measured together, matched against real frame sizes — and honest about when the two pull in different directions.
Frame size decoder

The three numbers stamped inside your glasses, explained and checked against your PD, including what the fit costs in lens thickness.
Lens thickness calculator

Whether the thinner lens is worth the money, in millimetres. Counts the decentration and astigmatism that free calculators leave out.
Reading glasses strength

The rack chart asks your age and assumes you read at 40 cm. This asks where you actually hold the page, which is worth two dioptres.
Progressive lens fit checker

Whether the frame you like is deep enough for progressives, which design it can carry, and how much reading area a shallow one costs you.
Eye prescription reader

SPH, CYL, AXIS and ADD in plain words, with both cylinder notations side by side and honest lens index guidance.
Contacts and glasses converter

A lens on your cornea is not the same number as one twelve millimetres away. Converts both ways, with the full vertex chart.
Visual acuity converter

20/20, 6/6, decimal and logMAR converted in both directions — plus what legal blindness actually requires, which is not what you have read.

Colour and skin

The lighting in your photo decides the answer unless something corrects for it. These correct for it first, then measure.

Personal colour analysis

Your twelve-season palette, with the room's lighting taken out of it by correcting against the whites of your eyes.
Skin undertone finder

Cool, warm or neutral measured in a colour space, not guessed from wrist veins — with an olive prompt where the reading warrants one.
Foundation shade matcher

Depth and undertone measured along the jaw, given as a coordinate that works at every counter, because no photo can honestly name a brand shade.

Face and proportion

Geometry, reported as geometry. No scores, no rankings, and every threshold published so you can disagree with the result.

Face shape detector

Seven shapes from four widths and one length, with the full decision trace shown — so you can tell a clear result from a coin flip.
Face symmetry test

Paired features measured in millimetres against a midline fitted to your own face, with head turn and expression accounted for.
Body shape calculator

Proportions from three measurements, with every ratio and threshold published. No weight, no BMI, no ideal.

Privacy

Tools whose whole point is that nothing leaves your device.

Blur faces in a photo

Redaction that never uploads the thing you are trying not to share, with honest advice on which of the three methods is actually safe.

Why the numbers are on show

A tool that says "you have a heart-shaped face" and nothing else is asking you to take it on faith. We would rather show the four widths and the two ratios that produced the answer, tell you which frames were rejected and why, and publish the spread across measurements so you can judge whether to trust a single reading.

That applies most of all to measurements you are about to spend money on. If your pupillary distance comes out at 63.5 mm give or take two millimetres, that is a different situation from 63.5 give or take a quarter, and a tool that hides the difference is not helping you.
