Miniature Bases vs. Polyhedral RPG Dice
Comparing 2 standards across 20 specifications. 20 key differences identified.
Miniature bases are standardized plastic platforms used in tabletop wargaming (Warhammer 40,000, Age of Sigmar) and tabletop RPGs (D&D) to define model footprint, line of sight, and melee engagement range. Official standards specify round bases from 25 mm (infantry) to 160 mm (monsters), and oval bases from 60×35 mm (cavalry) to 170×105 mm (large vehicles).
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.
