Otja: Photo Clothing Measure

Photograph your garment next to an A4 sheet of paper or a credit card. Otja uses the reference object's real size to compute the photo's scale, so connecting two points on the photo gives you real measurements. No tape measure needed. ■ Photos never leave your device There is no server. All processing happens on your device, and your photos and measurement records are never uploaded. ■ Built for secondhand sellers Get the length, shoulder width, and chest width you need for listings on eBay, Depop, Poshmark, Vinted, Mercari, and more — from a single photo. Then: · Copy the size chart as text and paste it into your listing · Save or share an image with the measurement lines drawn on it · Keep a record per item ■ Keep a record of your own clothes Measure the clothes that fit you best and keep them on file. Next time you shop online, compare the listing's size chart with your own measurements — fewer sizing mistakes, fewer returns. ■ How it works 1. Place an A4 sheet or a card on the same flat surface as the garment and take one photo. 2. Otja finds the reference's four corners and corrects perspective. If auto-detection struggles, tap the corners yourself. 3. Pick a category to get measurement slots like shoulder width, chest width, and total length. 4. Connect two points to see the value in cm or inches. ■ About accuracy Accuracy depends on how you shoot. Lay the garment flat, keep the reference on the same surface, and shoot as close to straight-down as you can. A large reference like A4 paper is recommended. The app warns you when choosing a small reference like a credit card, as long measurements may be less accurate. ■ Otja Pro (optional) A single one-time purchase unlocks unlimited records, custom reference objects, all measurement templates, and watermark removal. Core measuring is free.
