Roll a D10: Ten Sided Dice Roller
This free d10 roller is for DnD players, Dungeons & Dragons fans and game masters who need a fair ten sided die for heavy weapons, hit dice or a cantrip like Fire Bolt. Tap the die to roll, set how many d10s you want and add a modifier. The page covers what a d10 does in 5e, why a printed 0 usually means 10, and how this die pairs with a second d10 to make a percentile roll.
Tap the die to roll 1d10. Space and Enter work too.
Average for 1d10: 5.5 (before you roll)
How to use the d10 roller
Tap to roll. Press the big die to roll. Space and Enter work too once the page has focus, unless you are typing in a box.
Set the count and modifier. One d10 is the default. Raise the count when a feature, a higher-level spell or extra hit dice call for more than one, and type a modifier so the total includes your bonus.
Read every face. Several d10s list each face under the total. Faces are numbered 1 through 10 here, never 0, so the result matches what 5e expects. The average for your current notation is shown before you roll.
For typed notation such as 1d10+4, or to mix dice, use the main DnD dice roller. For exact odds, open the dice probability calculator.
What a d10 is used for in 5e
The d10 is not a platonic solid. It is usually a pentagonal trapezohedron: ten kite-shaped faces. Most sets include two of them, because a second d10 (often numbered 00, 10, 20 and so on) turns the pair into percentile dice.
On its own, a d10 is a solid damage die. Glaives, halberds, pikes and heavy crossbows all deal 1d10. A longsword, battleaxe or warhammer also uses a d10 when you wield it with two hands. Fire Bolt deals 1d10 fire damage at lower levels and adds more d10s as the cantrip scales.
The fighter, paladin and ranger use a d10 as their hit die. That makes this page handy when someone levels up or spends hit dice after a short rest. You can also roll the level-up total on the hit points roller. New to the bag? See what dice you need for DnD.
Why a 0 on a physical d10 means 10
Many physical d10s number their faces 0 through 9, with 0 standing in for 10. In Dungeons & Dragons you still read that die as 1 through 10. A roll that shows 0 is a 10, not a miss and not zero damage.
The exception is percentile work. If one die is the tens die (00 through 90) and the other is the ones die (0 through 9), then 00 and 0 together mean 100, while 00 and 7 mean 7. For a plain damage roll or hit die, ignore that pairing and treat a lone 0 as 10. This roller never shows a 0, so you do not have to remember the translation.
Using a d10 as half of a d100
A percentile roll, or d100, is a number from 1 to 100. The usual physical method is two d10s: one die read as tens and one die read as ones. If you want the finished 1 to 100 result in one tap, use the d100 roller. If you want to see both dice, roll twice here and assign one result as tens (multiply a 1 to 10 result by 10, treating 10 as 00) and the other as ones.
Most groups prefer a dedicated percentile roll when they are on a loot table, a wild magic table or another d100 chart, because it removes the extra arithmetic.
Average d10 roll
The average d10 roll on this d10 roller is 5.5. The average of one d10 is 5.5. Each face from 1 to 10 has a 10% chance. With a +4 modifier the average total is 9.5. Two d10s average 11. There is no special "natural 10" rule on damage or hit dice; a 10 is simply the highest face.
More than a d10
Attacks still start on the d20 roller. Other dice in the set have their own pages: the d4, d6, d8, d12 and d100. New characters can roll scores on the stat roller. How each roll stays fair is explained on the about page and in the FAQ.
d10 roller FAQ
Is this d10 roller free?
Yes. It is free, with no ads and no sign up. Open the page on any device and roll.
What is the average d10 roll?
The average of one d10 is 5.5, which is (1 + 10) divided by 2. Each face has a 10% chance. Two d10s average 11.
Does a 0 on a physical d10 mean zero?
In D&D, a d10 is read as 1 through 10. On many physical dice the 10 is printed as 0. That 0 counts as 10, not as zero. This roller shows 1 through 10 directly so there is nothing to translate.
What is a d10 used for in 5e?
A ten sided die covers glaive, halberd, pike and heavy crossbow damage, plus versatile two-handed damage on a longsword, battleaxe or warhammer. It is the hit die for the fighter, paladin and ranger, and Fire Bolt deals 1d10 fire damage at lower levels. A second d10, numbered in tens, pairs with this die to make a d100.
How is a d10 different from a d100?
A d10 returns 1 to 10. A d100, or percentile roll, returns 1 to 100. You can roll a d100 on its own page, or roll two d10s (one for tens and one for ones) if you like to see both dice.
Is the d10 roll truly random?
Each dice roll draws random numbers from your browser's cryptographic generator. Values that would favor a face are thrown out and drawn again, so all ten faces have the same 10% chance.
