What Size Sleeves Do Yu-Gi-Oh! Cards Need?
Yu-Gi-Oh! cards are 59 x 86 mm and take Japanese-size sleeves around 62 x 89 mm, not the standard sleeves used for Pokemon and Magic.
Card size is not universal. Pokémon cards are 63.5 × 88 mm and Magic: The Gathering cards 63 × 88 mm, both taking "standard" sleeves around 66 × 91 mm. Yu-Gi-Oh! cards are 59 × 86 mm and need Japanese-size sleeves around 62 × 89 mm. A Yu-Gi-Oh! card physically fits a standard sleeve but sits loose and shifts, which is why the sizes are sold separately.
