Designing to card size
If you are laying out artwork at card size, work in millimetres — the standard is defined there, so you avoid rounding drift. A common setup is an 86 × 54 mm document with 3 mm bleed on each side and a 3 mm safe margin inside the trim, keeping text clear of the rounded corners.
Watch out for charts that round the height to 54 mm. The real figure is 53.98 mm, and while 0.02 mm is invisible in a wallet, it matters if you are cutting a batch of cards or machining a slot to hold one. Use the exact value when precision counts.
