Learn how to measure Euro-size cards, choose Mayday Premium Euro Card Sleeves, and sleeve cleanly with a step-by-step process that avoids bent corners and misfits.
Quick answer
Use Mayday Premium Euro Card Sleeves for cards measuring 2.32" x 3.62" (59mm x 92mm). Measure a card first, then sleeve from the open edge with steady pressure to avoid bending corners.
Why Euro-size sleeves are not one-size-fits-all
Euro-style games often use cards around 59mm x 92mm, but not every card in a box matches that size. Expansion decks, promo cards, and smaller reference cards can differ, so check each deck before ordering sleeves. Mayday Premium Euro Card Sleeves are made for the 59mm x 92mm size; if a card is outside that range, this sleeve is the wrong fit.
What the 50-count pack means for a full game
Each pack contains 50 sleeves, so count the cards you plan to protect before buying. A game with 100 standard Euro cards needs two packs; a game with a mix of sizes needs separate sleeves for each size. Buying one pack first lets you test the fit on a single card before committing to a full set.
Premium thickness and archival safety
These sleeves are 125% thicker than standard sleeves and made from clear, acid-free polypropylene with no PVC. That thickness adds stiffness and a more substantial feel, but it also means a full deck will be taller than with thin sleeves. Check that your game box or insert has enough room for the extra height before sleeving every card.
How to sleeve Euro cards step by step
- Measure one card from the deck: Use a ruler or caliper to measure the card's width and height in millimeters. Compare the result to 59mm x 92mm. If the card is larger or smaller, do not force it into this sleeve. Measure a card from each distinct deck in the game, not just the first one.
- Count the cards you plan to sleeve: Count only the cards that match the Euro size. Divide that number by 50 to determine how many packs of Mayday Premium Euro Card Sleeves you need, rounding up. Set aside cards that do not match the size so you do not accidentally sleeve them.
- Insert the card from the open edge: Hold the sleeve by its edges and slide the card in from the open side. Push it in until it sits just below the sleeve's top edge, leaving a small margin. Do not push the card all the way to the sealed edge; a small margin prevents corner stress.
- Check for corner bending: After inserting, look at the card's corners through the clear sleeve. If a corner is catching or bent, slide the card out and reinsert it straight. A bent corner is a sign of misalignment; fix it before moving to the next card.
- Press out excess air: Hold the sleeved card between clean fingers and gently press from the center outward to push air out the open edge. Do not squeeze the card itself. Air pockets make shuffling uneven; a gentle press improves the feel.
- Test the fit in your game box: Sleeve one full deck and place it back in the box or insert. Check that the lid closes without pressure. If the stack is too tall, consider sleeving only the cards used most often. Box fit is separate from card fit; confirm both before sleeving the entire game.
