Life-size comparison
See the Duo at true size on your screen, open and closed, next to your current phone.
How this works
Calibrate first. Screens pack pixels differently, so the tool asks you to match an on-screen outline to a real bank or ID card (ISO/IEC 7810 ID-1, 85.60 × 53.98 mm). That gives your screen’s pixels per millimetre, saved on this device only. Skip it and the tool uses 96 pixels per inch, which is only approximate.
True scale. Every outline is drawn at its listed millimetres times your calibration. If an outline is wider than your screen, it stays at true size and the canvas scrolls instead of shrinking.
Simplified outlines. Devices are drawn as rounded rectangles with a generic corner radius and no camera bumps. The differences panel lists the exact numbers and how each one is calculated.
