How to Design a Loyalty Card for a Local Business: Size, Stamp Layout and Print Specs
Most loyalty cards fail for a boring reason: nobody designed them. Someone opened a free template, dropped a logo on it, printed 500 on flimsy paper and wondered why half of them ended up in the bin by Friday. A good loyalty card design is a retention tool disguised as a piece of card, and the details (size, number of stamp slots, where the terms sit, what stock it is printed on) decide whether the customer keeps it in their wallet or forgets it exists. This is the walkthrough we use at The Crazy Pixel when a local business asks us for a punch card. Everything below is print-ready: real dimensions in mm and inches, bleed values you can hand to a printer, and layout rules based on how people actually use these cards at the counter. Why the card itself drives repeat visits A loyalty card works because of two psychological levers, and both are design decisions, not marketing decisions. Visible progress. People finish what they can see they have started. Empty slots create a small, physical sense of an unfinished task. This is why a card with 8 visible boxes outperforms a vague “ask us about our rewards” note. Endowed progress. If the card arrives with one or two stamps already given (“here’s your first stamp, on us”), completion rates go up compared to a card that starts empty, even when the number of purchases required is identical. Everything else in the design either supports those two levers or gets out of the way. Standard loyalty card dimensions Ninety percent of the time you want a card that fits a wallet the same way a bank card does. That is not a style choice: a card that fits nowhere gets thrown away. The team at vistaprint.com reached a similar conclusion. Format Trim size (mm) Trim size (in) Best for Europe / UK business card 85 x 55 3.35 x 2.17 Default choice in the EU, 6 to 10 stamps US business card 88.9 x 50.8 3.5 x 2.0 Default choice in North America Credit card / ISO CR80 85.6 x 53.98 3.37 x 2.13 Plastic membership cards, barcode or magstripe Square 65 x 65 2.56 x 2.56 Design-led cafes, 9 stamps in a 3×3 grid Slim / bookmark 85 x 40 3.35 x 1.57 Single row of 5 to 8 stamps Folded card (4 panels) 170 x 55 folded to 85 x 55 6.7 x 2.17 folded 12+ stamps, salons with multiple services Our recommendation for most local businesses: 85 x 55 mm in Europe, 3.5 x 2 in in the US. It fits every wallet, every card slot, and every printer already has that format on its standard price list, which keeps the unit cost low. Rounded corners or square? Rounded corners (2 to 3 mm radius) survive the wallet much better. Square corners on a 300 gsm card start fraying after three weeks in a back pocket, and a battered card signals “almost done, replace it” to nobody except the bin. Rounded corners usually add a small die cost, but for a card designed to live in a wallet for two months it is worth it. How many stamp slots convert best? This is the single most important number on the card, and most businesses get it wrong by aiming too high. The team at kittl.com reached a similar conclusion. The rule: the customer must be able to imagine finishing the card before they lose it. Match the number of slots to your natural visit frequency so the card completes in roughly 4 to 8 weeks. Business type Typical visit frequency Recommended slots Reward Cafe / coffee shop 2 to 5 per week 8 to 10 10th drink free Bakery / lunch spot 1 to 3 per week 8 Free item up to a set value Barbershop Every 3 to 5 weeks 5 to 6 6th cut free or half price Hair salon (colour, cut) Every 6 to 10 weeks 4 to 5 Free treatment or 50% off a service Nail bar / beauty Every 3 to 4 weeks 6 Free file and polish Car wash / pet grooming Monthly 5 6th visit free Design tricks that raise completion Pre-stamp the first slot. Print a fake “welcome” stamp in the first box, or hand-stamp it at signup. A card that is 1/8 complete feels started. Make the last slot look different. A star, a gift icon, a filled colour block, or the word FREE. The eye needs a finish line. Keep slots big enough to stamp. A 12 mm self-inking stamp needs a box of at least 14 mm. Tiny 8 mm circles get overstamped, smudged and end up ambiguous, which causes arguments at the till. Don’t ask for money amounts. “Spend 10 get a stamp” adds friction and maths. One visit, one stamp is faster and staff won’t skip it during a rush. Never print more than 10 slots on a single small card. If you need 12 or more, go folded or use a slim card with two rows. Stamp layout: the practical geometry Here is how the space works on a standard 85 x 55 mm card. Assume a 4 mm safe margin from the trim edge on all sides, which leaves a usable area of 77 x 47 mm. A comparable breakdown sits on canva.com.

Stamps on the back, brand on the front. The front is your shop window: logo, one line telling the customer what the deal is, and nothing else fighting for attention. The back is the working surface. This split also means the card looks clean and
