Measure a card you already like, then pick the model that suits how much you carry.
How to measure
Measure a card you already carry and like the feel of — a bank card is 85.6 × 53.98 mm and is the reference for most of our wallets.
- Hold a ruler flat against the long edge of your card
- Measure the card itself, not the slot it came in
- Add nothing; our slots are cut to the card plus 1 mm of tolerance

If you are between sizes
Go up if you carry folded notes or a coin. Go down if you only carry a card or two and prefer something that disappears into a pocket.
Our leather softens slightly with use, so a snug fit at the start is normal and loosens over a few weeks. If a card will not slide in after a month of regular use, contact us for a free adjustment.
