A WYSIWYG utility for previewing and printing design assets at accurate 1:1 physical dimensions. Calibrate once using a physical anchor (ID card or ruler), then preview and print at true scale.
Place a physical ruler against your screen and adjust the scale below until the on-screen ruler matches exactly 100 mm. This calibrates the pixel-per-mm ratio for your display.
For a true 1:1 print, select "Actual Size" / 100% in the print dialog. Ensure "Fit to page" is turned off.
