Sometimes it’s important to start right from the very beginning.

One of the first things that new players are likely to notice about D&D is the assortment of curiously shaped dice.

In time, new players will turn into dice goblins who hoard their giant bags of clicky-clacky math rocks like the rest of us.

But before that transformation happens, it’s worth taking a closer look at the iconic dice of D&D! This post will cover each type of dice, when to use them, and what they’re used for.

How to Read Dice in D&D

Each individual die is named with the letter “D” followed by the number of sides that it has. For example, a twenty-sided die is called a “D20.”

So a roll that requires you to roll 2D20 would need you to roll two D20 dice.

The roll on the dice is most commonly represented by whatever number is facing upwards, though there are a couple of exceptions that we’ll get to in the next section.

Explaining Each of the Dice You’ll Use in D&D

 A standard set of dice includes: D4, D6, D8, two D10, D12, and a D20.

You’ll likely want multiple sets (or my favorite big ol’ bag of dice!) to make larger rolls easier.

For example, you can roll 4d6 all together for a spell like Guiding Bolt rather than rolling your d6 four times!

That said, let’s get into our explanation of what each of the dice are and what they are used for!

Twenty Sided Die (D20)

The d20 is the most iconic dice in D&D

The D20 is the most important thing in your dice bag. Nearly every roll that you make in D&D will involve at least one of these.

You’ll usually be needing it for:

  • Attack Rolls
  • Determining turn order in combat (aka initiative)
  • Skill Checks
  • Ability Checks
  • Saving Throws

As you might expect, these are the most common rolls in the game.

Twelve Sided Die (D12)

The d12 is a favorite of Barbarians

Generally speaking, the D12 is likely to be your least rolled die unless you’re playing a Barbarian.

This is generally used for one of two things:

  • Barbarian’s Hit Die
  • Damage Rolls with heavy weapons like a Greataxe

Particularly with the greataxe being a favorite weapon of many Barbarians, you’ll definitely be using this if you’re playing one. Otherwise, you’ll likely almost never have a reason to roll this one.

At a quick glance, these can get mistaken for the D20. Always double-check to make sure you’re rolling the correct dice!

As a DM, I’ll sometimes use this as a random generator for hours, months, or other measurements.

Fancy name: Dodecahedron

Ten Sided Die (D10)

d10 can also be used to roll for percentages.

There are two types of D10s: single and double digit.

The double digit ones are used for percentile rolls which we’ll cover in a moment.

Rolling a 0 on a D10 is a result of 10. The other results (1-9) are whatever is shown on the face.

D10 are used for:

  • Paladin and Fighter class hit dice
  • Some weapons (such as using two hands to swing a longsword)
  • Some spells
  • Percentile Dice

Fancy name: Pentagonal Trapezohedron

Eight Sided Die (D8)

The d8 is used for a bunch of different weapons, hit dice, and class features.

The d8 looks like two conjoined pyramids and is one of the more common dice you’ll be rolling.

Weapons like rapiers, Longbows, and longswords use a d8 for their damage. Additionally, most classes use the d8 for their Hit Dice.

D8 are used for:

  • Most classes’ Hit Dice
  • Many weapons
  • Several Spells
  • Bardic Inspiration, Battlemaster Maneuvers

Fancy name: Octahedron

Six Sided Die (D6)

The d6 or, as they’re known by non-RPG players, “dice.”

The D6 is what most people envision when they hear that the game involves rolling dice.

I’ll never forget one of my friend’s reaction when he was going to play his first game of D&D with our group. I told him he can borrow my dice. He said he can just grab some from his Yahtzee game.

“Oh, it’s not that kind of game. You need special dice!” I said.

My friend stared back at me.

“There’s more than one kind of dice?” he said with clear confusion.

D6 are usually used for:

  • Wizards Hit Dice
  • Several Spells
  • Many Weapons
  • Rolling Ability Scores at Character Creation

Fancy name(?): Cube

Four Sided Die (D4)

You only have to step on one d4 to never make that mistake again.

Pro Tip: if you find yourself being chased by a monster or psycho killer, the D4 make for very effective caltrops. Just throw a handful of them on the ground and they’ll butcher your pursuer’s feet.

In the far more likely event that you have kids or your group tend to accidentally roll dice off of the table, you’ll learn to fear the humble D4 with every fiber of your being.

Ask me how I know…

But beyond making for traps that would make Kevin McCallister from the Home Alone movies proud, the D4 is used for:

  • Small weapons (like daggers)
  • Some spells (like Healing Word)

Because of their triangular shape, these dice don’t roll particularly well. I recommend shaking them in your hands and doing more of a “toss” to prevent them just sliding on the same number over and over.

Fancy name: Tetrahedron

Three Sided Die (D3)

There are some very rare situations where you’ll find yourself needing a D3. These include recharging some magic items, determining family relationships within the Explorer’s Guide to Wildemount book, and some of the Path of Wild Magic Barbarian’s features.

In these situations, you can roll a D3 by:

  • Rolling a D4, re-roll a result of four
  • Roll a D6, divide the result by 2 and round up. (1-2 = 1, 3-4 = 2, 5-6 = 3)

Though I find an absolutely beautiful D3 made by Reddit user u/Nvenom8. You can check out the CNET feature here.

Percentile Dice (D100)

From time to time, the DM may ask a player to roll percentile dice.

This might be to determine random encounters or to use the Cleric’s Divine Intervention feature.

There are three ways to do this:

  • Roll 2d10. One of these should be the double-digit one to represent the “10s” place and the other one represents the “1s” place. (So a roll of “2” and “40” would be “42”)
  • Roll 2d10. If you don’t have a double-digit one handy, try to use two different colors of dice. Declare which one is the “10s” place and roll.
  • Assert your dominance at the table with a d100. Yes, these are just as fun to roll as you are thinking.

In the case of the first two methods, rolling zeroes on both dice is a result of 100.
