Why does MTG card size matter?

Competitive play

An MTG card’s dimensions are particularly important for competitive players, as cards with a uniform size help to prevent cheating. According to tournament rules, any card that is markedly different from the others in an MTG deck is considered an illegal, marked card. And though it isn’t one of the specific examples listed by Magic judges, card size differences could be considered a form of marking.

The best thing to do is to sleeve your cards. Any card could differ from standard sizing due to printing errors, so sleeves help keep everything uniform.

Spotting fakes

The most expensive MTG cards can be worth hundreds of thousands of dollars, so it helps to know what the real ones look like. Sizing is just one of many factors that might be considered when checking if a card is real or counterfeit.

Here the size of everything on the card counts. This doesn’t just include the general dimensions – understanding the size and spacing of font, art, and borders can all help identify a legitimate card, too. One or two mistakes could be a misprint, but several may indicate something suspicious.

With that out of the way, let’s answer the biggest MTG dimensions questions:

How big is an MTG card?

According to the official Magic: The Gathering rules, a ‘traditional’ MTG card size is 2.5 inches (6.3cm) by 3.5 inches (8.8cm). Non-foil cards are roughly 0.012 inches (0.305mm) thick, and foil cards are fractionally thicker.

Printing errors aside, there are some exceptions. These come under the category of ‘non-traditional cards’ in the official Magic rules. One example includes cards from the 1997 Vanguard MTG set, which were three inches by five inches.

What does an MTG card weigh?

The standard Magic card weight is somewhere between 1.7 and 1.8 grams. There will of course be some variation (printing isn’t perfect), but this is the rough ballpark any authentic MTG card will be in.

MTG playmat size

There’s no official MTG playmat size according to the comprehensive Magic: The Gathering rules. However, if you’re still curious, the average size is 24 inches by 14 inches (61.0 cm by 35.6 cm)

MTG deck size

An MTG deck size depends on which of the MTG formats you’re playing. Constructed formats like Standard and MTG Modern require a minimum of 60 cards, but there’s no maximum deck size. If you have a sideboard, this can include up to 15 cards.

In a limited format like an MTG draft, the standard deck size is 40 cards at the minimum. Again, there’s no maximum deck size. And this time, there’s also no size restrictions for your sideboard.

MTG maximum hand size

The maximum hand size in a Magic: The Gathering game is usually seven cards. If you have more than seven cards in your hand during the cleanup step, you must discard down to seven. There are exceptions – certain cards can alter your hand size during play.
