Card Sleeve Sizes: Find the Fit Before You Buy

The chart below sorts by its column buttons and downloads as CSV. Sizes describe the card or manufacturer fit class. Where the external sleeve dimensions are not independently stated, that column says so. We do not quietly convert a nominal “standard” label into a measured 66×91 mm product.

Pokémon, Magic and Flesh and Blood fit Dragon Shield’s standard class; its manufacturer size guide also lists Lorcana. For One Piece, use the exact listing’s stated standard compatibility, not an assumption based on another TCG. We have left Star Wars Unlimited and Riftbound out of the brand-specific chart until the required publisher/manufacturer fit evidence is recorded.

Board-game totals are edition-specific planning figures from the existing June 30, 2026 dataset, not a claim that we counted Robert’s copies. Follow each row’s source and measure a sample when the edition or printing differs.

Use a millimetre ruler on a bare card, edge to edge, without bending or marking it. Record width and height. Check whether the game also has investigator minis, tall reference cards, square cards or oversized boards. “One game” need not mean “one sleeve packet.”

For a close fit, choose the manufacturer’s stated card-compatibility dimensions. A physical sleeve must have seams and clearance around that card, so its outside will be larger. The familiar 66×91 mm figure is a common external standard-sleeve size, not the size of a Magic card and not an independently measured specification for every pack here.

Mini USA 41×63 and Mini Euro 45×68 are different fit categories. Tarot 70×120 is taller again. A merchant’s list of compatible games can hide multiple card sizes or printing changes; do not apply one sleeve size to every component in Gloomhaven, Spirit Island, Nemesis or another mixed-format box.

The Perfect Fit is an inner. The Matte Standard is the normal playing sleeve. The Clear Outer product in this inventory is an oversleeve for an already sleeved card, often to protect art sleeves. It is not a substitute for the ordinary middle playing sleeve.

For double-sleeving, slide the card into a top-loading inner, turn that sleeved card, then gently insert it into the playing sleeve so their openings face opposite directions. Let trapped air escape without crushing the card. If the stack resists, stop and check the product combination.

Triple-sleeving is an optional specialised choice. It adds bulk, shuffling friction and storage demands. Do not promise a 100-double-sleeved case will also hold 100 triple-sleeved cards. Keep the deck’s backs and wear consistent; mixing different batches can create visible differences. Check the event rules for competitive play.

For one 100-card Commander deck, single-sleeving needs 100 playing sleeves. Double-sleeving needs 100 inners plus 100 playing sleeves: 200 individual layers, not two complete decks. Tokens and spare sleeves are extra. Four double-sleeved Commander decks therefore use 800 sleeve layers.

Calculate packs as round up(cards ÷ sleeves per pack), separately for each size and layer. For the Chapter Two core’s 224 player cards, three 100-packs suffice. To sleeve all 362 full-size cards, buy four. Its five minis require their own fit category. Do not substitute the older Revised Core count of 361.

The Sleeve Calculator can help plan base-game quantities; its source dataset predates this article. Check edition notes and expansion counts rather than treating an older total as a fresh physical inspection. The separate sleeve buying guide compares brands and handling choices; this page answers size and quantity.

Matte backs can change grip and reflection; clear backs can preserve two-sided information. Neither word establishes a precise external dimension. For cards whose reverse is part of play, make a deliberate visibility choice rather than sleeving everything in opaque black.

The listed Perfect Fit is 60 μm; the Japanese Matte line states 120 μm; this Mini Euro product states 40 μm. These are attributed product specifications, not our measurements or a universal definition of durability. Never add a guessed thickness to a product merely because it says “premium.”

Japanese-size and tarot cards need their own fit classes. Use the manufacturer references to identify the correct version; the standard playing sleeves below are not interchangeable with those smaller or taller formats.

A card box’s nominal count depends on sleeve brand, layer count, trapped air, foil/card stock, dividers and token trays. Measure your actual finished stack, then verify that the lid closes freely without pressure on the cards.

Ultimate Guard’s Shaxs Squaroe states 100 double-sleeved or 120 single-sleeved cards using Ultimate Guard sleeves. That is manufacturer evidence for its own setup, not our test of Dragon Shield layers. The larger Game’s Lair is an organisation option for multiple decks; its advertised configurations do not establish the same capacity for every combination.

Leave room for tokens and transport. For a new deck, the sensible order is cards → chosen sleeves → gently tested stack → case. Buying the most expensive chest first can leave you solving the wrong fit problem.

If a casual game rarely shuffles its cards and replacements are easy, sleeves may add more handling than value. Protect the parts you use, not a hypothetical future collection. For collectors, protection does not guarantee condition, grade or resale value.

This is a sourced dimensions-and-counts reference, not a hands-on comparison. Robert’s storage-fit project can add real measurements later; no generated lab scene is evidence that those tests already happened.
