PVC Card Thickness: 10, 20 & 30 Mil Explained
The three common PVC card thicknesses look almost the same in a catalog photo — but they feel and perform completely differently. Here's how to pick the right one for your project.
Quick answer
- 30 mil (0.76 mm): the standard CR80 credit-card thickness. Use for ID badges, loyalty cards, gift cards, membership cards, and premium plastic business cards.
- 20 mil (0.51 mm): a mid-weight card. Use for short-run loyalty or membership cards where cost matters more than "credit-card feel."
- 10 mil (0.25 mm): thin and flexible. Use for temporary badges, punch cards, event passes, and mailer inserts.
What "mil" actually means
A mil is one one-thousandth of an inch (0.001″). It has nothing to do with millimeters. A 30 mil card is 0.030″ thick — about the same as three sheets of standard printer paper stacked together. The industry standard for ID and payment cards is 30 mil, defined by ISO/IEC 7810 as the CR80 format (85.60 × 53.98 mm).
30 mil PVC cards — the standard
If someone hands you a card and it feels like a credit card, it's 30 mil. Every card printer, wallet slot, badge reel, and swipe reader on the market is designed around this thickness. Choose 30 mil when you need:
- Employee, student, or contractor ID badges that clip to a lanyard or badge reel.
- Loyalty, membership, or gift cards that customers keep in a wallet.
- Premium plastic business cards that make a statement.
- Any card that runs through an Evolis, Zebra, Fargo, or Magicard printer.
- Cards with magnetic stripes, smart chips, or embedded NFC tags — the extra body protects the chip and antenna.
Trade-off: 30 mil is the most expensive of the three, and heavier for large mailings.
20 mil PVC cards — the middle ground
20 mil cards are about two-thirds the thickness of a credit card. They still feel like a real plastic card in the hand, but flex a little more and cost less. They're a smart pick for:
- Short-run loyalty cards where cost per card matters.
- Membership cards mailed in bulk (lower weight = lower postage).
- Direct-mail promotions where customers keep the card short-term.
Heads up: most dye-sublimation card printers won't feed 20 mil stock reliably. If you need to run cards through an Evolis or Zebra printer, go with 30 mil.
10 mil PVC cards — thin and light
At 10 mil, cards are flexible and easy to slot punch, perforate, or mail flat. They're not meant to live in a wallet — think of them as heavy-duty plastic sheets sized like a credit card. Best for:
- Disposable event badges, day passes, and visitor tags.
- Punch cards ("buy 10, get 1 free") that live on a fridge or in a jar.
- Mailer inserts, hangtags, and promotional handouts.
- Any project where you're printing thousands of cards on a budget.
How to choose in 30 seconds
- Does the card go in a wallet or a card printer? → 30 mil.
- Does it need a chip, magstripe, or NFC tag? → 30 mil.
- Is it a short-run loyalty or mailed membership card? → 20 mil.
- Is it disposable, temporary, or a punch card? → 10 mil.

Thickness is one of those things that's much easier to feel than to describe. If you're between two options, request a printed sample first — we'd rather send you a card to hold than have you reprint an entire run in the wrong stock.
