Size Calculation

Size Calculation measures your body with your phone's camera and tells you the right size for the garment you are looking at. No measuring tape, no guesswork — hand the phone to someone or prop it up, and the spoken guide does the rest.

HOW IT WORKS
• Scan the QR code on a shop's product page — that is how the app knows which garment you are being measured for
• Position the phone at chest height, about 2 metres away
• Follow the spoken instructions: a few seconds facing forward, then a 90-degree side turn
• The scan starts and finishes by itself; you never press a button

WHAT IT MEASURES
Height, chest, waist, hip, shoulder width, arm length and inseam. Every value is written in both centimetres and inches, so there is no unit to choose.

HONEST ABOUT ACCURACY
Measurements come from the silhouette the camera sees, placed at true scale using the phone's motion tracking. Typical deviation is a few centimetres: this does not replace a tailor's tape, but it is enough to choose a size. Every scan reports an accuracy rate, and when it is low the app asks you to scan again rather than sending a doubtful measurement.

THE SIZE COMES FROM THE GARMENT'S OWN CHART
The app never asks for your gender, fit preference, brand or size system. All of that arrives with the product behind the QR code. When a garment is cut close, the roomier size is offered as well.

PRIVACY
Camera and depth data are processed on your device. Nothing is recorded and nothing is uploaded. Your measurements leave the device in exactly one way: you scan a company's QR code and confirm on a screen that names the company and lists every value that would be sent. That step is always optional.

REQUIREMENTS
Android 8.0 or later on an ARCore-supported device. If your device is not supported the app opens and says so plainly. For best results, wear close-fitting clothing and scan in a well-lit room with clear floor space.
