Simply take a photo, and the AI will measure the size of the object, allowing you to use the screen as a real measuring tape.
Magic Photo Ruler is an AI measurement app that tells you the actual size of an object using just a single photo. Its key features include: AI measurement using photos, automatic recognition of reference objects that allow measurement without a ruler, measurement of multiple objects and detailed dimensions by part within a single photo, a precision digital measuring tape that uses your phone screen as is, screen calibration using a credit card, saving measurement records, and support for 12 languages.
AI Measurement Using Photos
When you photograph an object to measure or select one from your gallery, the AI automatically calculates its width, length, and height. You can also specify the object directly, such as by saying, "Measure the chair."
Automatic Recognition of Reference Objects
It automatically identifies standard objects in the photo, such as credit cards, A4 paper, or coins, and uses them as references. If there is no suitable reference, it estimates the size using surrounding clues, such as water bottles or door heights, so there is no need to keep a ruler nearby. Multiple Objects and Detailed Dimensions
Measure multiple objects simultaneously from a single photo and analyze dimensions for specific parts, such as chair seat height or armrest height. Each result is provided with a reliability score and a retake guide.
Precision Digital Tape Measure and Screen Calibration
You can use your phone screen as a real tape measure (cm/mm and inches). Place a standard credit card on the screen and adjust the size using the −/+ buttons to create an accurate tape measure that fits the device perfectly; once calibrated, the calibration is maintained.
Record Saving and Multilingual Support
Measurement results are saved on the device, allowing you to review photos, summaries, and detailed dimensions. It supports 12 languages, including Korean, English, Japanese, German, Spanish, French, Hindi, Indonesian, Portuguese, Russian, Vietnamese, and Arabic. When you switch languages, the AI result explanation is also displayed in the corresponding language.
