How to Print Custom Trading Cards at the Exact Card Size

The Perfect Print Team · June 18, 2026 · 6 min read

We're the Perfect Print team. You made your own trading cards or fan cards, then "they're loose in the sleeve" or "they won't fit the toploader." A trading card's fit changes with just a few millimeters. This article covers the size to set so your custom cards fit standard sleeves and cases exactly, plus how to keep printing from throwing the size off.

Set the size to match what it goes into

Size your custom card to the sleeve or case you'll use. The long-standing industry standard is 2.5 x 3.5 inches (about 63 x 89mm) — the same size used by Magic: The Gathering, Pokémon, Yu-Gi-Oh!, and sports cards, and what penny sleeves, toploaders, and one-touch cases are all cut for. If you're matching a non-standard case, measure its inside dimensions and pick a card size that sits inside it.

The key is to decide in real inches, not by how it looks on screen. Print "about this big" and a few millimeters of error means it won't slide into the sleeve, or it rattles around. We built Perfect Print to make those few millimeters easy to nail on your phone.

Why "close enough" printing fails

Scaling a card image in a photo editor doesn't decide its printed size. And if you print with "fit to page" at home or a store, it auto-scales off your target. It matched on screen but won't fit the sleeve is almost always the size changing at this step. The tighter the fit — and cards are tight — the more you need to lock real size before printing.

How to size and print cards in Perfect Print

Pick a paper size (a letter sheet works well) and load the card image. Enter the card's width and height in inches to place it at real size. To match a sleeve, base it on the standard 2.5 x 3.5 inches, and set it a hair (a couple of millimeters) under the sleeve's inside dimensions so it slides in and out smoothly. Millimeter precision lets you fit your exact case.

Lay several same-size cards on one letter sheet and save to print a batch — cheaper per card. Always set printing to actual size (100%) so they come out at the dimensions you set. Adding faint cut lines in the margins makes them easier to trim straight. Print one, slide it into a sleeve to check the fit, then run the rest.

Frequently asked questions

What's the standard trading card size?

The industry standard is 2.5 x 3.5 inches (about 63 x 89mm) — used by major TCGs and sports cards. If your case is non-standard, measure its inside dimensions and size to fit.

How do I get a snug sleeve fit?

Set the card a couple of millimeters under the sleeve's inside dimensions so it goes in easily and doesn't shift. Perfect Print's millimeter precision lets you tune it to your sleeves.

Can I print several at once?

Yes. Lay same-size cards across one letter sheet to make a batch and lower the cost per card. Add faint cut lines to make trimming easy.

My cards print the wrong size.

"Fit to page" auto-scales them. Print at "actual size," "100%," or "no scaling" to get the dimensions you set. Print one and check it in a sleeve before running the rest.
