Sizesnap Lab

Buying or selling, it comes down to numbers. Measure the garment that already fits, and the size question is settled in centimeters.

Lay a garment flat, tap the two ends, and Sizesnap Lab measures it in AR — keeping the numbers together with the photo you measured.

■ No tape measure Your camera reads the surface the garment rests on. From there you just tap: shoulder seam to shoulder seam for shoulder width, center back neckline to center hem for body length. Swipe up or down to switch the part you are measuring.

■ The garment that fits becomes your reference Measure something that already fits you well and save it to your closet. Measure anything you are considering the same way, and the difference appears part by part — how many centimeters wider in the shoulders, how many shorter in the body. You judge by real numbers instead of an "M" or an "L".

■ Every measurement stays with its photo Measurements go into your closet alongside the photo. Tops, bottoms, outerwear and dresses are organized by type, and you can revisit them as a list or a gallery.

■ Ready for resale listings Turn the measurements into a size description you can copy straight into a marketplace app. You can also share the photo and the size text together as one set.

■ Not just clothes Anything you can lay flat works — a bag, a hat, a cushion. Custom measurements let you name and measure exactly the points you care about.

■ Your data stays on your device Measurements and photos are stored only on your device. No account, no ads.

Note: the dimensions shown are estimates produced from the camera and AR, and conditions affect the result. The app is designed for comparing garments measured the same way.
