There are two main trading card sizes: Standard-size and Japanese-size. One common misconception is that trading card games originating in Japan, such as Pokémon, must use Japanese-size cards. However, this isn’t always the case. Pokémon, Magic: The Gathering and several other popular TCGs actually use larger standard-size cards, whilst Yu-Gi-Oh!, Cardfight!! Vanguard, Battle Spirits and others alternatively use a smaller Japanese-size format.
So, which size is right for your trading card game, and where did these different sizes originate? We’ll answer both questions below, helping you identify the correct size for your cards whilst exploring the history behind both formats.
The sizes side by side
Japanese-size cards (59 x 86mm) are 4mm narrower and 2mm shorter than Standard-size cards (63 x 88mm). That might not sound like much, but it’s the difference between a snug fit and a card that slides around (or won’t fit at all).
To find out which size your card might be, ‘Japanese-size’ or ‘Standard-size‘, check our Find Your Trading Card Size table below.

Why are Japanese trading cards not always Japanese-size? 🇯🇵
The game that made Japanese-size cards famous worldwide was Yu-Gi-Oh!. Konami launched the Yu-Gi-Oh! Official Card Game in Japan in February 1999, using the smaller card format also associated with Bandai’s Carddass collectibles. These date back to 1988, when they were sold through vending machines, with early series including Saint Seiya. Carddass-based games, including Battle Spirits and Dragon Ball Heroes, later used the 59 × 86 mm format.
When Yu-Gi-Oh! arrived in North America in March 2002, Konami kept the same smaller card size, helping establish the format internationally.
As Yu-Gi-Oh! grew in popularity across the West, card sleeve manufacturers needed to distinguish this smaller format from standard-size cards. The term “Japanese-size” became widely used, alongside “small-size” and “Yu-Gi-Oh! size”.
Meanwhile, Pokémon, despite originating in Japan, uses the “Standard-size” format (63 × 88 mm), also used by Magic: The Gathering. This helped align Pokémon with the established American trading card market. This is where the confusion comes from, so it’s always worth checking your trading card size before purchasing card protection.
