If you are printing custom cards, tokens, or proxy-style test cards, this MTG card size guide is the part you do not want to wing. A Magic-sized card looks simple enough on screen. Then you upload the file, and suddenly the border feels off, the corners eat your text, or the art shifts just enough to bother you every time you shuffle. It happens fast.
The good news is that most of the pain comes from a few predictable setup mistakes. Once you know the actual card dimensions, how much bleed to add, where the safe zone really is, and why thin borders are risky, the whole job gets easier. In my opinion, this is one of those areas where being boring pays off. Good print files are rarely exciting. They are just correct. And correct is what keeps your cards from coming back looking slightly cursed.
MTG Card Size Guide Starts With The Trim Size
The standard target size for an MTG-sized card is 2.5 x 3.5 inches. In metric, you will usually see either 63 x 88 mm or 63.5 x 88.9 mm. That tiny difference is where a lot of confusion starts.
Here is the simple version. Printers often work from one of two habits. Some use the exact inch conversion, which lands at 63.5 x 88.9 mm. Others round to a cleaner metric standard, which becomes 63 x 88 mm. Both show up in card-printing workflows. So when two templates disagree by a fraction of a millimeter, that does not always mean one is wrong. It usually means they were built from different measurement systems.
That said, do not mix and match. Pick the printer’s template and stay loyal to it all the way through the job. If their file says 63 x 88 mm, use that. If their template is built around 2.5 x 3.5 inches, use that. The numbers are close, but not close enough to freestyle.
A quick reference looks like this:
- Trim size: 2.5 x 3.5 in
- Common metric template: 63 x 88 mm
- Exact inch conversion: 63.5 x 88.9 mm
- Corner radius: about 3 mm
- Typical non-foil thickness target: around 0.30 to 0.305 mm
If your goal is sleeve compatibility and that familiar hand feel, these are the numbers that matter first.
Bleed And Safe Zone Matter More Than Most People Think
A good MTG card size guide is not really just about size. It is about what happens around the edges.
Most print workflows use 1/8 inch bleed on each side. That means your design file is bigger than the finished card. If the final trimmed size is 2.5 x 3.5 inches, your full file with bleed becomes 2.75 x 3.75 inches. At 300 DPI, that works out to 825 x 1125 pixels. The trim-only size at 300 DPI is 750 x 1050 pixels.
That extra space is not decoration. It is insurance. Cutting is precise, but it is not magic. If your background stops exactly at the trim line, even a tiny shift can leave a white sliver on the edge. Bleed is what prevents that.
Then there is the safe zone. This is the area where your important text, mana symbols, names, and frame details should stay comfortably inside the trim. Different templates express it a little differently, but the rule is the same: keep anything important away from the edge and especially away from rounded corners.
This is where people get annoyed, and i get it. On screen, pushing text a little farther out often looks better. In print, that decision comes back to bite you. A card can still be technically printed right and feel wrong because the bottom line of text sits too close to the corner cut.
Resolution, Color Mode, And Export Settings
Once your dimensions are right, file quality becomes the next filter. For small printed pieces like cards, 300 DPI is the standard baseline. Lower than that, and you start inviting fuzzy rules text, soft line art, and gradients that look rougher than they did on your monitor.
If you are building your file from scratch, set the document up at full size from the beginning. Do not make a small web image and try to “upgrade” it later. That usually just creates a bigger blurry file. More pixels are not the same thing as better detail.
Color mode matters too. Print workflows are built around CMYK, not RGB. If you leave a file in RGB, bright screen colors can shift during conversion. Blues can move, greens can flatten out, and very saturated colors can lose some punch. This does not mean your file is ruined. It means your screen is lying a little, which is honestly one of printing’s oldest traditions.
For exports, follow the printer’s template and preferred file type. Some shops want high-resolution PDFs. Others may work from flattened PNG or TIFF artwork. The safest habit is simple: use their template, export cleanly, and do not leave live guides or hidden notes hanging around in the file.
Why Borders, Corners, And Small Text Cause Trouble
If I had to pick one issue that shows up over and over in custom card files, it would be thin borders too close to the edge.
They look sharp on screen. In print, they can come out uneven after trimming. Even when the cut is within normal tolerance, a hairline border can make the whole card look off-center. That is why printers regularly warn against relying on ultra-thin outer borders near the cut line.
The fix is not complicated. Either pull the border farther in so a slight shift is less noticeable, or make it thick enough that the variation does not read as an error. Trying to split the difference is where most bad-looking borders live.
Corners are another quiet problem. MTG-sized cards use rounded corners, usually around a 3 mm radius. So if your frame detail, collector marks, or decorative linework sits too tight to the corners, the rounding can nibble at it. It is a tiny cut, but your eye catches it right away.
And then there is text. Small card text is less forgiving than people think. You do not need to panic, but you do need to respect scale. If your art, frame, and rules box all fight for space, the printer is not the one who loses that argument. You are.
Printing MTG Proxies, Tokens, And Custom Cards Without Rework
The nice thing about printing MTG proxies, tokens, and custom cards is that the physical setup stays pretty stable once you know the file rules. The card face may change a lot. The print logic does not.
Tokens are the easiest place to get creative because you are not boxed into the exact same information density as a full card frame. You can let the art breathe a bit. You can simplify. But if you want the token to sleeve and shuffle alongside other cards comfortably, keep it at the same MTG-sized dimensions and follow the same bleed and safe zone rules.
Custom cards are where people often overbuild. Too many effects. Too much contrast. Too many thin lines. The best-looking printed cards are usually cleaner than the first version on your screen. A little restraint helps more than another texture layer ever will.
If you want more production background, Briarwood already has a useful post on How MTG Cards Are Made and Printed. And if you are still sorting out stock feel, thickness, or surface finish, their guide to the best cardstock for MTG is the next logical read.
That is really the workflow. Get the size right. Build with bleed. Keep the safe zone honest. Use 300 DPI. Respect CMYK. Avoid fragile border choices. Then upload without crossing your fingers.
A Simple Preflight Check Before You Upload
Before you send a card file to print, run through this short check:
- Confirm the template size matches the printer’s card format
- Make sure bleed extends past every edge
- Keep text and critical frame elements inside the safe zone
- Export at full size, 300 DPI, in the requested file type
- Check borders, corners, and tiny text one last time at 100%
That last step matters more than people think. Zoomed-out files hide problems. Real cards do not.
Conclusion
A solid MTG card size guide is really a print setup guide in disguise. The core numbers are easy enough to remember, 2.5 x 3.5 inches, 1/8 inch bleed, 300 DPI, CMYK, and careful spacing from the edges. The harder part is sticking to them when you are tempted to squeeze in one more border effect or let text creep too close to the corner.
If you remember one thing from this MTG card size guide, make it this: most bad card prints are not ruined by the art itself. They are ruined by preventable setup choices. Get the file right first, and the rest of the job gets a lot less frustrating.
