D4 Dice Roller — Roll a Four-Sided Die Online
Dagger damage, darts, Magic Missile — roll your D4 here.
What Is a D4?
The D4 is a four-sided die shaped like a tetrahedron — a triangular pyramid, the simplest of the Platonic solids. It's the odd one out in a standard polyhedral dice set: every other die (D6, D8, D10, D12, D20) lands with one face pointing up, but a tetrahedron has no single "up" face at all. Instead, three of its four triangular faces touch the table when it comes to rest, and the fourth points into the air.
Because of this, reading a physical D4 takes a moment of practice. Depending on how the die is printed, you either read the number at the base — the digit shared by the three faces resting on the table — or the single apex number printed at the tip pointing upward. Different manufacturers use different conventions, which is one reason a lot of players simply reach for a digital roller like this one instead of squinting at a tiny pyramid on the table.
When Do You Roll a D4?
In Dungeons & Dragons 5e and most other d20-system RPGs, the D4 is the standard damage die for the lightest weapons. A dagger deals 1d4 piercing damage, a thrown dart deals 1d4 piercing damage, and a sling deals 1d4 bludgeoning damage — small, fast weapons that trade raw damage for speed and reach.
The D4 also shows up in spellcasting. Magic Missile, one of the most recognizable low-level spells, conjures three glowing darts of magical force; each dart deals 1d4+1 force damage and never misses, for a combined 3d4+3 at first level. Use the 3-dice option above to roll all three darts in one click.
Looking for a full DnD dice roller that covers every damage die, not just the D4? Our main dice roller supports D4 through D100, or head to the D20 Roller for attack rolls and saving throws.
Frequently Asked Questions
How do you read a D4?
A D4 is a tetrahedron, so it never lands with a single flat face pointing up. Instead you read the result at the bottom edge — the three numbers printed around the base that touches the table — or, on dice with numbers at each corner, the single apex number pointing straight up. Check which style your physical die uses; this online roller always shows the correct result instantly, no reading required.
What is 3d4 used for?
3d4 (rolling three separate D4s and adding them) is the shorthand many players use for Magic Missile damage in D&D 5e: the spell fires three darts, each dealing 1d4+1 force damage, for a combined 3d4+3 at first level. Select 3 in the quantity selector above to roll all three darts at once.
Is this D4 roller truly random?
Yes. Every roll uses JavaScript's Math.random(), which modern browsers back with a cryptographically strong random number generator. Each of the four outcomes (1, 2, 3, 4) has an equal 25% chance on every roll, and no roll depends on the ones before it.
