D4 Dice Roller
Roll one or more four-sided dice online — the smallest standard polyhedral die, commonly used for dagger and spell damage in D&D.
Roll history
Your rolls will appear here.
The d4 is shaped like a pyramid rather than a cube, since a four-sided cube isn't possible, and it has the lowest average roll of any standard polyhedral die. This d4 dice roller gives you a clean 1-to-4 result without needing to read a tricky tetrahedron by hand.
What Is a D4 Used For?
In D&D and similar games, the d4 usually shows up for smaller weapons and low-damage spells rather than as a core resolution die.
- Dagger and sickle damage
- Many first-level cantrip and spell effects
- Healing potions and minor magic item rolls
Rolling Multiple D4s for Damage
Set the dice count to match your weapon or spell — for example, 2 dice for a spell that deals 2d4 damage — and add any bonus in the modifier field to get the final total in one roll.
Frequently asked questions
What weapons use a d4 in D&D?
Light weapons like the dagger and sickle typically deal 1d4 damage, and several low-level spells use d4 dice as well.
How do I roll 2d4+1?
Set the dice count to 2 and enter 1 in the modifier field, then roll — the tool sums both dice and adds the modifier automatically.
Why is a d4 shaped like a pyramid?
A cube with only four usable faces isn't geometrically possible, so the tetrahedron (pyramid) shape is the standard way to make a fair four-sided die.
