Quick answer
For random tables, a D100 die gives you a single-roll 1-100 result with maximum granularity, while a D20 offers speed and smaller physical size. The right choice depends on your need for precision versus convenience.
Why granularity matters on random tables
Random tables, like treasure hoards, NPC quirks, or weather effects, often use a percentile roll. A D100 delivers that result in one roll with 100 distinct outcomes. A D20, even when paired with a D10, gives only 20 unique results unless you combine it with a second die—slowing the game down. If your table has 100 entries, a D100 is the direct tool.
The size and handling trade-off
D100 dice are large—often golf-ball sized or bigger—so they can be awkward to roll in tight spaces. The Orb D100 and Pounder D100 are hefty metal dice that feel substantial but may not fit a cramped dice tray. A D20 is smaller and easier to pocket, but you'll need to pair it with a percentile die or do math to simulate a D100. The trade-off: one big roll versus two smaller ones.
D100 vs D20: Trade-offs for random tables
- Single-roll precision: A D100 gives you a direct 1-100 result in one roll. No math, no second die. Perfect for tables with 100 entries.
- Physical size: D100 dice are large and heavy. The Orb D100 and Pounder D100 are metal and may not fit small dice trays or be comfortable for frequent rolling. If space is tight, a D20 pair may be more practical.
- Cost and availability: Metal D100 dice cost more than standard D20s. The Orb D100 is available for pre-order, while D20s are widely available in many materials. Weigh the investment against how often you use random tables.
