7 Wonders, designed by Antoine Bauza and published by Repos Production, is one of the most-played card-drafting games on the market, and for good reason: three rounds, constant hand-passing, and a satisfying civilization-building arc in under half an hour.
It's also one of the clearest examples of a board game that does not use a standard trading card size, which catches out a lot of buyers who assume any card-heavy game will fit ordinary TCG sleeves.
Getting the sizing wrong here is a genuinely common and avoidable mistake, since the mismatch is large enough to be obvious the moment a card goes into the wrong sleeve.
Here's the real card dimension, how many cards are actually in the box, and what to do about protection given that EVORETRO's standard sleeve lineup won't fit this one.
7 Wonders cards measure 65mm by 100mm, a longer, narrower rectangle than the 63.5mm by 89mm standard poker size used by most trading card games. Specialty sleeve sellers that list exact fit data, including sleeveyourgames.com and Ryker Games' dedicated 7 Wonders sleeve kits, consistently confirm this same 65 by 100mm dimension across both the original and second editions.
This size is sometimes called Magnum size in the sleeve industry, and it's shared by only a handful of other games, which is exactly why it causes confusion. A card that looks only slightly larger than standard at a glance is actually a meaningfully different shape once you try to fit a sleeve to it.
The 7 Wonders base game (second edition) contains 148 Age cards, split across three eras: 49 Age I cards, 49 Age II cards, and 50 Age III cards, confirmed consistently across BoardGameGeek's listing and publisher Asmodee's own product materials. On top of the Age cards, each player also receives one of seven double-sided Wonder boards, which are thick cardboard pieces rather than sleeve-size cards.
7 Wonders Duel, the two-player spinoff, uses a different card pool and its own dedicated sleeve kit, so buyers who own both the base game and Duel should treat them as two separate sleeving projects rather than assuming compatibility.
Because 65 by 100mm sits well outside the 63.5 by 89mm standard poker footprint, a standard-size sleeve will be visibly too short and slightly too narrow for a 7 Wonders card. Forcing the fit either leaves the card loose enough to slip partway out or creases the top edge against the sleeve seam.
EVORETRO's current sleeve lineup is built around standard poker-size cards, which covers the large majority of trading card games but does not cover this particular Magnum-size format. Buyers specifically chasing a sleeve fit for 7 Wonders need a dedicated Magnum-size sleeve from a specialty board game sleeve brand rather than anything sized for standard TCG cards.
Given the sleeve-size gap, the more practical move for most 7 Wonders owners is prioritizing organized, unsleeved storage over forcing an imperfect sleeve fit. Separating the three Age decks and keeping them from mixing between sessions matters more for this game's setup speed than full sleeving does anyway, since each round only uses one Age at a time.
The EVORETRO Resealable Team Bags work well for exactly this kind of pre-sorted storage, letting a player split the deck by Age before it ever goes back in the box, which speeds up setup on the next game night considerably.
Even without sleeves, 148 loose cards benefit from a dedicated container rather than rattling around the game's original insert, which wasn't designed with repeated handling in mind. A compact deck box keeps the full Age card set together and protected from bent corners during transport to a friend's house or a game night.
The EVORETRO Plastic Deck Box, built from 0.7mm polypropylene, comfortably holds the full 148-card Age deck in one container, which is a meaningfully better setup than leaving cards loose in the original box insert long-term.
65mm by 100mm, often called Magnum size, not standard poker size.
148 Age cards total: 49 Age I, 49 Age II, and 50 Age III.
No, the 65 by 100mm size is too large and the wrong shape for standard poker-size sleeves.
It uses a separate card pool with its own dedicated sleeve kit, so don't assume compatibility.
While you track down Magnum-size sleeves, keep your Age decks sorted and travel-ready with the EVORETRO Plastic Deck Box.
