What is the Card Sleeve Calculator?
The Card Sleeve Calculator helps tabletop gamers and trading card collectors determine exactly how many individual packs of protective sleeves they need to purchase to fully cover their board game or Trading Card Game (TCG) collection.
How to Calculate Card Sleeve Requirements (Formulas)
Calculating sleeve quantities requires knowing the total card count and the package size of the specific brand you are buying.
- Calculation Formula: Total Packs Needed = Total Cards in Game / Number of Sleeves per Pack.
- Note: Always round up to the nearest whole pack to account for tearing or future expansions.
Frequently Asked Questions
What are standard size card sleeves?
Standard size sleeves typically measure 66mm x 91mm. They are designed to fit the most popular TCGs in the world, including Magic: The Gathering (MTG), Pokémon, and the Dragon Ball Super Card Game. Standard cards themselves are exactly 63mm x 88mm (2.5 by 3.5 inches).
What are Japanese size card sleeves?
Japanese or "Mini" size sleeves measure 62mm x 89mm. They are designed for physically smaller trading cards, most notably Yu-Gi-Oh! and Cardfight!! Vanguard. Putting a Yu-Gi-Oh! card in a Standard sleeve will result in a very loose fit that can damage the card during shuffling.
Why should I double-sleeve my cards?
Double-sleeving involves putting the card in a tight-fitting "inner sleeve" (opening at the bottom), and then sliding that into a standard "outer sleeve" (opening at the top). This creates a near-waterproof seal that protects expensive, rare cards from spills, dust, and aggressive shuffling.
