MTG card dimensions follow one strict standard — 63mm x 88mm — but the details around sleeves, printing, and deck rules trip up a lot of players.
This guide breaks down the exact Magic: The Gathering card size, how it fits sleeves and paper, and the deck-building rules that go with it.
Standard MTG Card Dimensions Chart (MM, Inches & Pixels)
| Measurement | Value |
|---|---|
| Millimeters | 63mm x 88mm |
| Exact math conversion | 63.5mm x 88.9mm |
| Inches | 2.5″ x 3.5″ |
| Thickness | 0.30mm to 0.32mm |
| Pixels (300 DPI) | 744 x 1039 px |
The 63 x 88mm figure is the industry standard used by Wizards of the Coast, sleeve makers, and printers — even though the exact math conversion from inches comes out slightly larger at 63.5 x 88.9mm. That small rounding gap is why some sleeves fit snugger than others.
MTG Card Dimensions and Sleeve Fit
Standard sleeves measure roughly 66mm x 91mm, giving just enough room for a card to slide in without tearing the sleeve seams.
Double sleeving is a common protection method among competitive players. A tight “perfect fit” inner sleeve wraps the card at its exact 63 x 88mm dimension, then slides inside a looser 66 x 91mm outer sleeve for extra durability.
Storage products are built around this same footprint. Nine-pocket binder pages and standard deck boxes all use the 2.5″ x 3.5″ poker card size as their baseline measurement.
MTG Card Dimensions vs. Standard Paper (Printing & Legality)
How many MTG cards fit on an 8.5 x 11 sheet? At 2.5″ x 3.5″ per card, a standard letter sheet fits nine cards, arranged three rows by three columns with small trim margins.
Is it illegal to print MTG cards? Printing cards for personal proxies — unofficial stand-ins used in casual playtesting — is widely tolerated. Selling counterfeit cards, however, is not; it violates Wizards of the Coast’s copyright and trademark rights and can carry real legal consequences.
MTG Deck Size and the 75% Rule
Is the standard MTG deck size 40 or 60 cards? Both exist. Limited formats, including Draft and Sealed, use a 40-card minimum. Constructed formats like Standard and Modern require a 60-card minimum, not counting the sideboard.
What is the 75% rule in MTG? It’s a casual Commander guideline, not an official rule. It suggests building decks to be fun and competitive roughly three-quarters of the time, rather than optimizing purely to win every single game. Many playgroups use it to keep Commander matches balanced and enjoyable.
MTG Card Dimensions vs. Other Trading Cards
Are MTG cards bigger than Pokémon cards? No. Pokémon cards share the exact same 2.5″ x 3.5″ (63 x 88mm) footprint as MTG cards, which is why both fit the same sleeves, binders, and deck boxes.
This shared sizing isn’t a coincidence — it’s the standard poker card dimension used across most modern trading card games, making cross-game storage simple for collectors who play more than one.
