Hotel Key Card Size and Standards

Size is the most common question in a key card enquiry. The short answer: virtually every card reader in use expects the same standard card footprint as a bank card.

Standard
Same footprint as a bank card
Thickness
Produced to reader tolerance
Custom cut
Fobs and shaped formats
Validation
Pre-production sample testing

Why the standard matters

Door locks, front-desk encoders, lift readers and in-room energy savers are all built around the same footprint. A card outside that footprint may fit a pocket but jam in a slot reader or fail to trigger the energy switch.

That is why our wood, paper and leather cards are produced to the standard footprint — only the texture and body material change.

Custom shapes

Corner radius, hole position, key-fob formats and bespoke die-cuts are all possible. Where slot readers are in use we always validate a custom shape on a pre-production sample; with contactless readers the design freedom is far wider.

Frequently asked questions

+Do wooden key cards fit standard slot readers?

Yes, they are produced thin enough for standard readers, and we validate slot readers with a sample first.

+Can you produce a shaped key card?

With contactless readers, yes. For slot-based systems we recommend keeping the standard format.
