How it works
Three simple steps — calibrate once, see everything at real size.
Calibrate Your Screen
Match a familiar real-world reference — a local banknote, a credit card, or any ID card — against your screen. This measures your display's exact pixel density.
Select an Object
Browse our curated catalog of physical items including international coins, credit cards, standard paper formats, and popular smartphones.
See True Physical Size
The database size is mapped exactly to screen pixels using your DPI. Objects render at their real-world millimetric dimensions on your screen.
Popular real-world sizes
Explore standard items rendered at their true physical scale.
Put size into perspective.
Select two objects to compare their actual physical scales side-by-side on a unified baseline.
Relative proportions are accurate. Calibrate your display to render them at literal 1:1 scale on your screen.
