Phone AR measurement

Measure feet with your phone

Paper and ruler still work. A guided AR foot scan on your phone is the faster path when you want length and ball girth without a store visit.

Browser-based AR foot scanning walks you through a multi-angle capture on your phone. Existing product language on this site describes a guided 12-step scan that measures foot length and ball girth to within ±2 mm of a podiatrist scan (about 99% accuracy), with measurements staying on your device by default. It is a measurement aid, not a medical device.

Phone flow (overview)

  1. Open the scan from the web (App Clip or WebXR-style path depending on device).
  2. Grant camera access and follow on-screen pose guidance.
  3. Complete the guided multi-angle capture (about 30 seconds in the existing explainer).
  4. Review length and ball girth, then a per-model size suggestion with fit heatmap.

Accuracy note (existing on-site claim)

Reuse only: length and ball girth to within ±2 mm of a podiatrist scan (~99% accuracy), dependent on following guidance, lighting, and surface. Not a medical device.

Frequently asked questions

Do measurements leave my phone?

By default, the scan’s measurements stay on your device. Because it runs in the browser through an App Clip or WebXR rather than a persistent installed app, the foot data does not need to leave the phone to produce a size recommendation.

What does the scan measure?

Foot length (heel-to-toe, primary for size) and ball girth (circumference around the widest part). Width matters: two feet of the same length can need different sizes.

Can I convert the result to EU/US/UK?

Yes — use the shoe size converter and size recommender tools on this site after you know your length.
