Banknote Size Comparator
Pick two currencies and see every note drawn at one scale, sharing a baseline like notes fanned out on a table. Measurements come from the sources on each currency page.
Calibrate your screen. Hold any bank, credit or ID card against the bar below and drag until the two are exactly the same width. Every card in the world is 85.6 mm across, so this makes the notes life size. Your setting is remembered on this device.
Why size is a design decision
A currency that grows its notes with their value can be sorted by touch, and the difference is deliberate: it is an accessibility feature, not decoration. Compare the Indian rupee, which steps from 123 mm at ₹10 to 150 mm at ₹500, with the US dollar, where the Bureau of Engraving and Printing prints every denomination at the same 6.14 × 2.61 inches. A blind holder of rupees can measure the note; a blind holder of dollars has to fold, label or scan them.
Size constrains the machines, too. Cash handlers, ticket machines and ATM cassettes are built around a fixed size range, which is why a redesign usually keeps the footprint even when every other thing about the note changes.
Which currencies are missing?
A currency appears here only once we have verified dimensions for at least one of its notes. That is 36 of them so far, and the number rises as the data fills in: we would rather leave a currency out than draw it from a guess. Sources are listed on each currency page.
