MTG Card Size, Explained: Separating Myth from Fact

Here's the problem: search results are full of conflicting numbers. Some sites round to 2.5 x 3.5 inches, others throw in millimeters that don't match, and a few mix up trading card dimensions with tarot-sized variants entirely. If you're trying to design something that fits a standard sleeve, binder page, or magnetic case, a rounding error of even a few millimeters means your finished piece won't sit right. That's a real headache when you've already paid for printing.

The actual mtg card size is 63mm x 88mm, which converts to roughly 2.48 x 3.46 inches — not a clean 2.5 x 3.5. That tiny gap matters more than it sounds like it should, especially once you're working with custom photo cards instead of factory-printed ones. We print custom sports cards on premium card stock daily, and we've seen exactly where that half-millimeter difference trips people up.

Let's separate what's actually true about card dimensions from what's just repeated folklore.

The takeaway: a 63mm x 88mm MTG card and a 2.5" x 3.5" trading card are within a millimetre of each other, so anything built for one fits the sleeves, binders and toploaders sold for the other. Your custom card ships at the standard trading-card size, printed on premium card stock, so it sits in a collection exactly where a real card would.
