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

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.

Slots	Grid	Box size	Gap between boxes
5	5 x 1	13 mm circle	3 mm
6	3 x 2	18 mm circle	4 mm
8	4 x 2	15 mm circle	3 mm
9	3 x 3 (square card)	16 mm circle	3 mm
10	5 x 2	13 mm circle	2.5 mm

Which side do the stamps go on?

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 giftable when it is handed over, and staff always know which way to flip it.

One exception: if you want the reward to be visible every time the customer opens their wallet, put a small progress strip on the front edge. It is a nudge, not the main layout.

Circles, squares or icons?

• Circles forgive a slightly misaligned stamp better than squares. Safest default.
• Outlined icons (coffee cup, scissors, paw print) that get covered by the stamp look charming but reduce contrast. Keep them at 20 to 30% tint so the stamp reads clearly on top.
• Squares work when staff will tick with a pen rather than stamp.
• Give each slot a small number (1 to 10) inside or under the box. It makes progress explicit and prevents disputes.

Ink and paper compatibility

This is the mistake that ruins otherwise beautiful cards: you cannot stamp a matte-laminated or gloss-laminated surface. The ink beads and smears. Options:

• Leave the stamp area unlaminated (spot matte varnish or a laminate window).
• Use uncoated or lightly coated stock for the whole card.
• Use a hole punch instead of a stamp, which works on any finish.
• If you insist on soft-touch laminate, switch to a dry-punch tool or a signature/initials box.

Where to put terms, branding and contact details

A loyalty card is a tiny contract and a tiny billboard at the same time. Both jobs fit if you assign zones.

Front of the card

1. Logo, top left or centred, with real breathing room.
2. The offer in one sentence, larger than everything else: “Buy 9 coffees, the 10th is on us.” No jargon, no “points”.
3. Business name and city if the logo alone is not explicit.
4. Optional: a QR code linking to your booking page or Google review page. Minimum 15 x 15 mm with a 2 mm quiet zone or phones will struggle.

Back of the card

1. Stamp grid, taking roughly 60 to 70% of the surface.
2. Card holder line (name or phone) if you want data. Keep it optional or it slows down signup.
3. Terms, at the bottom, 5 to 6 pt, in grey rather than black so they read as fine print without looking sneaky.
4. Contact block: phone, Instagram handle, address, one line each.

The terms you actually need

Keep it to four short items. Long terms don’t fit and don’t get read:

• One stamp per visit / per purchase.
• Not valid with other offers or discounts.
• No cash value. Lost or damaged cards are not replaced.
• Expiry: valid 12 months from first stamp, or a printed end date.

An expiry date matters more than people think. It creates a deadline, and it stops you honouring a card from four years ago printed with old pricing. Put a small “Valid until” field the staff can fill in, or print the year on the batch.

Typography and colour on a small canvas

• Minimum body text: 7 pt. Minimum legal fine print: 5 pt. Below that, offset printing fills in the letterforms.
• Maximum two typefaces. Use your existing brand fonts.
• Contrast ratio matters even in print: pale grey on white fine print is unreadable for a big share of customers.
• Avoid full-bleed dark or black backgrounds unless you have a good reason. They show every fingerprint, every white scuff on the edges, and stamp ink disappears on them. If you must go dark, reverse the stamp slots out in white or a light tint.

Print specs to send to your printer

Copy this block, adjust the size, and you will avoid 95% of prepress emails.

Spec	Value	Notes
Document size	85 x 55 mm (trim)	Or 3.5 x 2 in for US
Bleed	3 mm each side (0.125 in US)	Document with bleed: 91 x 61 mm
Safe margin	4 mm inside trim	5 mm if rounded corners
Resolution	300 dpi minimum	600 dpi for hairline artwork or small text
Colour mode	CMYK	Convert RGB before export, or expect shifts
Colour profile	FOGRA39 / ISO Coated v2 (EU) or GRACoL (US)	Ask the printer which they prefer
Rich black	C40 M30 Y30 K100 for large areas	Small text: 100% K only
Minimum line weight	0.25 pt	Thinner strokes may drop out
Fonts	Embedded or outlined	Outline if you use unusual licences
File format	PDF/X-1a or PDF/X-4	Crop marks on, single pages not spreads
Pages	2 pages: front then back	Never supply back-to-back on one page

Cardstock: what weight and finish to choose

Stock	Weight	Stampable?	Verdict
Uncoated / offset	300 to 350 gsm	Yes, excellent	Best all-round choice for stamp cards
Silk / matte coated	300 to 400 gsm	Yes, but slower drying	Good compromise, richer colour
Gloss laminated	350 gsm +	No	Punch or tick only
Soft touch laminate	400 gsm +	No	Premium feel, needs a punch system
Kraft / recycled	300 to 400 gsm	Yes	Great for cafes, limited colour reproduction
PVC plastic (CR80)	0.76 mm	No	For scanned or app-linked programmes only

Below 250 gsm, don’t bother. A thin card feels disposable, so it gets treated as disposable. 350 gsm uncoated is the sweet spot: it feels substantial, takes stamp ink, and costs almost nothing more than 300.

A step-by-step design workflow

1. Decide the maths first. Reward value, number of visits, your margin. If the 10th coffee is free, you are effectively giving a 10% discount to your best customers. Make sure that works.
2. Pick the slot count from the frequency table above.
3. Set up the document at trim size plus 3 mm bleed, with a 4 mm safe margin guide.
4. Design the front around one sentence and the logo. If you have to shrink the logo to fit more text, remove text.
5. Build the stamp grid on the back using consistent spacing, then physically test it: print one at 100% on plain paper, cut it out, and stamp it with your actual stamp.
6. Add terms and contact in the bottom band.
7. Proof it at real size on paper, not on screen. Text that looks fine at 400% zoom can be invisible at 100%.
8. Export PDF/X-1a with bleed and crop marks, two pages.
9. Order a small first run. 250 to 500 cards. You will want to change something after a month of real use at the counter.

Design mistakes we see most often

• Text or logo too close to the trim edge. Cutting tolerance is around 1 mm on a guillotine. Anything within 2 mm of the trim will look off-centre on some cards.
• No bleed at all. A white sliver appears on one edge of a coloured card. Always extend background art 3 mm past the trim.
• Laminated stamp zone. Discussed above, and unfortunately very common with online template shops that laminate by default.
• Too many slots. 20 boxes on a barbershop card means a two-year commitment. Nobody makes it.
• Unclear reward. “Collect stamps for a free gift” motivates nothing. Name the reward.
• No place for the shop to sign or date. Without it, fraud is trivial: anyone with a similar rubber stamp can fill a card.
• Forgetting the staff. If the stamp box is 8 mm and the till is busy, the stamp lands half off the card. Design for a rushed hand.

Paper card, digital card, or both?

Paper stamp cards still win on cost, on speed at the counter and on the fact that nobody has to download anything. Digital wallet cards win on lost-card recovery and on letting you message customers. For most single-location salons, cafes and barbershops, paper first is the right call, with a QR code on the front pointing to a booking page or a wallet pass if you add one later.

If you do go digital, keep the visual language identical: same slot grid, same colours, same reward wording. A card the customer recognises in two forms is one brand, not two systems.

Quick pre-press checklist

• Fine print at 5 pt or larger
• Stamp boxes at least 14 mm, tested with the real stamp
• Stamp area unlaminated
• Expiry field or printed date present
• Terms limited to four lines
• Fonts embedded or outlined
• Exported as PDF/X-1a, 2 single pages, crop marks on

FAQ

What is the standard loyalty card size?

85 x 55 mm in Europe and the UK, or 3.5 x 2 in (88.9 x 50.8 mm) in North America. Both fit a standard wallet card slot. Credit card format (85.6 x 54 mm, ISO CR80) is used for plastic cards.

How many stamps should a loyalty card have?

Enough to be completed in about 4 to 8 weeks at your normal visit frequency. That means 8 to 10 for a cafe, 5 to 6 for a barbershop, and 4 to 5 for a hair salon. More than 10 slots on a wallet-size card hurts completion rates.

How much bleed do loyalty cards need?

3 mm on every edge (0.125 in in the US), plus a 4 mm internal safe margin for text and logos. So an 85 x 55 mm card is set up as an 91 x 61 mm document with crop marks.

What cardstock is best for a stamp card?

350 gsm uncoated or silk. It is thick enough to feel worth keeping and absorbs rubber stamp ink cleanly. Avoid gloss or soft-touch lamination on the stamp area, because the ink will smudge.

Can I design a loyalty card myself with a template?

Yes, template tools are fine for a first version, but check three things before printing: that the stamp boxes are at least 14 mm wide, that the file exports with 3 mm bleed, and that the finish you choose can actually be stamped. Those three points are where most template-based cards fail.

Should the loyalty card have an expiry date?

Yes. A “valid until” field or a 12-month validity from the first stamp creates urgency and protects you from honouring old pricing. State it in the fine print and let staff write the date at signup.

Stamp or hole punch?

A stamp looks better and works on uncoated stock. A hole punch works on any finish, including laminated and plastic cards, and is harder to counterfeit. Use a custom-shaped punch if you want both durability and brand character.

Need a card that people keep?

A loyalty card is one of the cheapest retention tools a local business can print, but only if the design respects the wallet, the stamp and the staff behind the counter. If you want a print-ready loyalty card design built to your brand, with the right slot count for your visit frequency and files your printer will accept first time, get in touch with The Crazy Pixel and tell us your business type and reward. We will handle the rest.
