[RPG] What does 1d20 mean in dnd?


I’m new to dnd and I’m having a hard time getting what all the stats mean, one of the things I’m having the most trouble with is things like, for example, 1d20. What does this mean and how does it apply to my stats?

Best Answer

The term "1d20" is a short notation for "1 die with 20 sides". So when there is the notation of "roll 1d20" you are asked to roll an Icosahedron, or 20 sided die. 3d6 likewise would be 3 dice of the cube type.

It is even explained in the rules, usually very close to the beginning. Like in the d&D5 basic rules, page 3:

Game Dice

The game uses polyhedral dice with different numbers of sides. You can find dice like these in game stores and in many bookstores.

In these rules, the different dice are referred to by the letter d followed by the number of sides: d4, d6, d8, d10, d12, and d20. For instance, a d6 is a six-sided die (the typical cube that many games use).
