iPhone

RefScale helps you measure real-world dimensions from a photo. Place a known object in the image, such as a credit card, phone, or custom reference size, then draw measurement lines to estimate width, height, and distance. RefScale is useful for checking package sizes, furniture fit, desk items, home objects, and other everyday measurements. Features: • Measure objects from photos using a reference object • Built-in presets for common cards and iPhone models • Custom reference objects with your own dimensions • Inches, feet/inches, millimeters, and centimeters • Zoom and fine-tune markers for precise placement • Export annotated measurement images Measurements are approximate and depend on camera angle, perspective, reference placement, image quality, and marker placement. For best results, keep the reference object and measured object on the same plane and take photos as straight-on as possible.
