Size Calculation

Measure your body with your iPhone's LiDAR scanner and get instant clothing size suggestions - private, on-device, no measuring tape needed.

Size Calculation turns your iPhone's LiDAR scanner into a precise body-measuring tool. In under two minutes it captures your key body measurements and recommends the right clothing size - no measuring tape, no guesswork.

HOW IT WORKS Using the LiDAR depth sensor together with on-device person detection, Size Calculation builds a true-to-scale 3D point cloud of your body. Because LiDAR measures real distances, there is no scale guessing - the foundation of accurate results. A quick two-phase scan (front A-pose, then a 90-degree side turn) is all it needs.

WHAT IT MEASURES

• Chest, waist and hip circumference
• Shoulder width
• Height
• Inseam and arm length

SMART SIZE RECOMMENDATION Your measurements are matched against EU/UK/US size charts to suggest the garment size that will actually fit, with a confidence indicator so you know how reliable each result is.

PRIVATE BY DESIGN All processing happens on your device. Your camera and depth data are never saved and never leave your iPhone. Your measurements leave the device only if you scan a company's QR code and confirm the transfer yourself - and that is always optional.

REQUIREMENTS A LiDAR-equipped iPhone (iPhone 12 Pro or later Pro models). For best results, have someone hold the phone about 2 metres away at chest height and wear close-fitting clothing.
