Card Sleeves vs. Polyhedral RPG Dice
Comparing 2 standards across 21 specifications. 21 key differences identified.
Card sleeves are protective polymer covers manufactured in standardized millimeter dimensions to fit trading card games (TCGs) and board games. The universal matrix spans Standard Size (66×91 mm for MTG, Pokémon, Lorcana), Small/Japanese Size (62×89 mm for Yu-Gi-Oh, Cardfight Vanguard), Perfect Fit/Inner Sleeves, and Tarot Sleeves, measured in micron thickness grades (50 to 120 µm).
Polyhedral dice are standardized 7-die sets used in tabletop role-playing games (TTRPGs) including Dungeons & Dragons and Pathfinder. A standard set consists of D4 (tetrahedron), D6 (cube), D8 (octahedron), D10 (pentagonal trapezohedron), D% (percentile tens), D12 (dodecahedron), and D20 (icosahedron), manufactured in standard 16 mm to 22 mm millimeter heights based on Platonic solids.
