D100 dice roller
A 100-outcome percentile roll for random tables, percentage checks and tabletop role-playing games.
How this die works
A D100 represents values from 1 to 100, with each result having a one-in-one-hundred chance. Physical percentile rolls are often made with two ten-sided dice: one for tens and one for units. This page uses a direct 1–100 result, so there is no need to interpret two dice.
When to use it
Use a D100 for percentile checks, 100-entry random tables, encounter tables and rules written as 1d100.
A fair digital roll gives each face an equal chance. This roller uses the browser's secure random number generator where available.
