What does 2d6+3 mean?

Roll two six-sided dice, add the results, then add 3. The number before the d is how many dice, the number after it is how many sides each die has, and +3 is a fixed modifier.

How many dice can I roll at once?

Up to 10 dice per roll, mixing any types from D2 to D100, plus a positive or negative modifier.

Dice Roller: Roll 3d20, 4d6, 10d4 or Any Dice Notation

Roll any dice with standard notation

Tabletop games write dice rolls as NdS+M: N is how many dice, S is how many sides each die has, and M is an optional number added to the total. So 3d20 means three twenty-sided dice, and 2d6+3 means two six-sided dice plus 3. You can mix dice too: 1d20+1d4+2.

Type the notation in the box above, or open a ready-made roll:

1d20 2d6 3d6 4d6 3d20 10d20 3d4 7d4 10d4 3d12 10d12 8d6 1d100 2d6+3

Common D&D 5e rolls

What you are rolling	Dice	Roll it
Attack roll or ability check	1d20 + modifier	1d20+5
Advantage or disadvantage	2d20, keep the higher or lower	2d20
Ability score (standard method)	4d6, drop the lowest die	4d6
Fireball (3rd level)	8d6	8d6
Magic Missile (1st level, three darts)	3d4+3	3d4+3
Potion of Healing	2d4+2	2d4+2
Greatsword damage	2d6 + Strength modifier	2d6+3
Percentile roll	1d100	1d100

Every die is shown separately, so for 4d6 drop-lowest or advantage you can see each value and keep the right one.

Dice odds worth knowing

1d20: every number from 1 to 20 has a 5% chance.
2d6: totals range from 2 to 12, and 7 is the most likely at 6 in 36, about 16.7%. A 2 or a 12 comes up only 1 time in 36.
3d6: totals range from 3 to 18. 10 and 11 are the most likely, each 27 in 216, or 12.5%.
More dice, more predictable: the more dice you add, the more the total clusters around the middle.
