A deck box listed as holding 100 cards doesn't actually hold 100 cards for every player. Sleeving method changes the real capacity significantly, and getting that wrong means a box that's either too tight or awkwardly loose.
A magnetic deck box adds a secure closure on top of that sizing question, which matters for players who transport decks to events regularly.
This guide covers how sleeving affects real capacity and how EVORETRO's magnetic deck box fits both single- and double-sleeved setups.
A box's stated capacity usually assumes a specific sleeving method, often single-sleeved cards. Double-sleeving, which adds a second protective layer for tournament play, takes up meaningfully more space per card.
That difference means a box rated for 100 single-sleeved cards might only comfortably hold 80 or fewer double-sleeved ones.
Single-sleeving is the standard approach for casual and kitchen-table play, maximizing how many cards fit in a given box size.
Double-sleeving is common in competitive and tournament settings, where the extra layer protects against wear during frequent shuffling, at the cost of reduced box capacity.
For players who want a secure, magnetic closure alongside flexible capacity, EVORETRO's Magnetic Deck Box holds up to 100 double-sleeved cards or 120 single-sleeved.
A magnetic closure keeps the box securely shut during travel to events, reducing the risk of cards spilling out compared to a simple flip-top box without a closure mechanism.
That matters most for players who regularly bring a deck to a store, tournament, or trade night rather than keeping it at home.
Before buying, decide whether your deck is single- or double-sleeved, since that choice directly affects how close to the box's stated capacity your actual deck will land.
Leaving some buffer room, rather than buying a box sized exactly to your current deck count, also accommodates future deck growth without needing an upgrade right away.
Double-sleeving adds a second protective layer that helps hide card identity from behind and reduces wear from frequent shuffling during tournament rounds, which is why many competitive formats see it as standard practice.
Casual and kitchen-table players often skip double-sleeving simply because the extra protection matters less for lower-frequency, lower-stakes play.
Beyond capacity, some players prioritize a slim profile for easy carrying, while others prioritize maximum capacity for larger Commander or multiplayer decks that exceed standard sixty-card formats.
Knowing your primary deck format and sleeving habit before buying avoids ending up with a box that's a poor match for how you actually play.
Players who occasionally switch between single- and double-sleeving, depending on whether they're playing casually or in a tournament, benefit from choosing a box sized around the more demanding double-sleeved capacity.
That approach means the box comfortably fits either sleeving method rather than being tight in one and loose in the other.
Players who maintain more than one active deck at a time often keep a matching magnetic deck box for each, using a consistent format across their whole collection rather than mixing box styles.
That consistency makes swapping between decks before different events or matchups faster and less confusing.
