What does Size Calculation do?

Size Calculation is a free iPhone and Android app that measures your body with the phone's camera — height, chest, waist, hip and more — and tells you which size of a shop's product fits you, using that product's own size chart. Measuring happens on the phone; camera images never leave it. In Turkish the app is called Beden Ölçer.

Where does the QR code come from?

A clothing shop that works with Size Calculation shows a QR code on its product page, in its shop or on a label. Scan that code with your phone's camera (or with "Measure with QR" on the app's home screen): the app opens, measures you, shows a confirmation screen listing what will be sent, and only after you tap "Confirm and send" do your measurements go to that shop. The app has no measurement button of its own — a measurement always starts from a shop's QR code.

Common problems

"This QR has expired. Scan the QR on the product page again."

A QR code from a product page is valid for a limited time, about an hour. Go back to the product page, scan the QR code shown there now and continue in the app. A screenshot or photo of an older code will not work.

"Not enough measurement data was collected. Please scan again."

The phone could not see you clearly enough. Place the phone upright at waist height with the screen facing you and step 2–2.5 m back, so you are visible from head to toe with some floor in front of your feet. Use a well-lit room and do not stand with a window behind you, wear close-fitting clothes, hold your arms a fist's width from your body and stand still until the scan finishes.

"Measuring needs camera access. Allow the camera in Settings, then come back."

The app needs the camera to measure and to read QR codes. On iPhone open Settings › Size Calculation and turn Camera on. On Android open Settings › Apps › Size Calculation › Permissions › Camera and choose Allow. Then return to the app.

How do I delete my data?

On your phone: swipe a measurement in the History list to delete it, or delete all of them in Settings › Data › "Delete all measurement history". Uninstalling the app removes everything it stored on the phone.

A measurement you shared with a shop: write to info@codeo.com.tr with the shop's name and the date of the measurement and we delete our record. There are no accounts, so that description is how we find it. The shop keeps its own copy; ask the shop separately to delete it. Details are in the Privacy Policy.

How do I contact you?

By e-mail at info@codeo.com.tr. Shops that want to offer Size Calculation on their own site will find the details on the page for clothing brands.
