# Foot Size Measurement — User Guide

This guide is for the shopper flow at [size.wearfits.com](https://size.wearfits.com). Stores embedding the button start at [Recommend a shoe size](../shoes/recommend-size.md), then the [SDK guide](sdk-guide.md).

The scan result is a size and width reading. An on-shoe fit picture is not part of this flow.

## Size-fitting demo

The public size-fitting demo is an interactive example rather than a live scan. It uses a static sample person and simulated fit indicators; use the size controls to see how different sizes affect the displayed fit. The demo does not capture photos, generate a profile, or make generation or API requests.

## Devices

| Platform | How scanning works |
|----------|--------------------|
| **Android** | Chrome, WebXR camera scan |
| **iOS** | Native **App Clip** (primary). Safari shows an App Clip card; the shopper taps **Open**. |
| **iOS fallback** | In-page web scan if the App Clip is not used |

Use a current Chrome on Android, or Safari on iOS. In-app browsers and private tabs may hide the App Clip card.

## Scan

1. Open [size.wearfits.com](https://size.wearfits.com), or follow a try-on link that sends the shopper here.
2. Allow camera access when the browser asks.
3. Follow the on-screen coverage guide until both feet are captured.
4. The app uploads the scan and opens the result page when processing finishes.

If the device already has a foot profile for this shopper, the app can skip the scan and go straight to results.

## Result page

The result page shows a compact foot profile: size plus width/girth, with EU / UK / US and cm / inch labels. Quality cues (for example left/right consistency) may appear when the scan supports them.

Results stay on WEARFITS domains so a sibling try-on page can reuse them. Stores using the SDK receive only an advisory recommendation, not the raw profile.

## Return to the shoe

A product page can send the shopper here with `?return_url=` pointing at that shoe page (same-site, safe URLs only). After the scan, the result page offers a **back to the shoe** action.

Notes:

- The return link is navigation only. Measurements are not placed in the URL.
- If the shopper already has a profile, they can return without scanning again.

## Languages

The scan UI defaults to English and includes Polish, French, and Spanish.
