The three ID card sizes
| Format | Size | Matches | Example |
|---|---|---|---|
| ID-1 | 85.6 × 53.98 mm | no ISO paper size | bank cards, driving licences, ID cards |
| ID-2 | 105 × 74 mm | A7 landscape | German ID card until 2010 |
| ID-3 | 125 × 88 mm | B7 landscape | passports |
It is no coincidence that ID-2 and ID-3 match A7 and B7: the card sizes were aligned with the existing paper sizes. Only the bank card, ID-1, stands apart.
