Size Calculation

Size Calculation turns your iPhone into a body-measuring tool. In under two minutes it captures your key body measurements and tells you the size that fits — read from the clothing brand's own chart for the exact garment you are buying. No measuring tape, no guesswork. HOW IT WORKS A measurement starts by scanning the QR code on a shop's product page, so the app knows which garment it is measuring for. Prop the phone up or hand it to someone about two metres away, face the camera, then turn ninety degrees; spoken guidance walks you through it. On Pro iPhones the LiDAR scanner measures real distances. On every other iPhone the app asks your height once and scales the scan from it, cross-checked against the floor the phone tracks. The same measurement engine runs in both cases. WHAT IT MEASURES - Chest, waist and hip circumference - Shoulder width - Height - Inseam and arm length YOUR SIZE, FROM THE BRAND'S OWN CHART The app never asks your gender, fit, brand or size system — the product's code carries all of that. Your measurements are matched against the size chart the brand uploaded for that garment, and when a cut runs close the roomier size is offered as well. Every value is shown in centimetres and inches together, with an accuracy rate for each scan. PRIVATE BY DESIGN All processing happens on your device. Camera and depth frames are never saved and never leave your iPhone. Your measurements leave the device only when you scan a company's QR code and confirm the transfer on a screen that lists exactly what will be sent — never silently, and never to anyone else. REQUIREMENTS Any iPhone from the XS and XR onwards. For best results, keep the phone about two metres away at chest height and wear close-fitting clothing. Measure smarter. Shop with confidence.
