Here’s how to roll a d100 online: set Sides per die to 100 and roll one die to obtain an integer from 1 through 100.

How to Roll a D100 Online

A practice game uses a direct hundred-sided result. The example returns a single value rather than two separate tens-and-units dice. The settings below match the worked example. Change them to match your activity. Nothing is generated until you select Roll dice.

Step-by-step instructions

  1. Choose the die size

    Set Sides per die to the die your activity needs, such as 6 or 20. The choices run from 2 to 100 sides.

  2. Set the number of dice

    Choose how many equal-sided dice to roll in this batch, up to 100. Mixed die sizes require separate saved batches.

  3. Roll and interpret the values

    Select Roll dice. Read each value individually or use the displayed total if your rules call for a sum.

Worked example

A practice game uses a direct hundred-sided result. The example returns a single value rather than two separate tens-and-units dice.

One valid result is shown below. Your generated outcome will vary.

Example settings

Sides per die: 100
Number of dice: 1

Example result

1. 73

Every output lies in 1–100. There is no 00 label in the tool’s raw output.

Agree on the game’s percentile convention

Some games interpret percentile results using special labels or thresholds. Use the convention in your actual rules and do not assume that the displayed integer automatically includes every game-specific interpretation. If you need two separately displayed ten-sided dice, record those rolls and apply the appropriate mapping yourself rather than treating their sum as a percentile result.

Settings and limits to check

Each die independently selects an integer from 1 through the chosen side count. Repeats are valid, so two six-sided dice can both show 4. The total adds the displayed dice but does not apply game modifiers, advantage rules, reroll conditions, or custom success thresholds. Those interpretations belong to your game rules.

Settings used in this example
Sides per die: 100
Number of dice: 1

Keep a usable copy of the result

Use Copy to place the current result in your own notes, or Download to keep a text file. Keep the range, count, or other settings with the result when they are needed to interpret it. A new generation replaces the displayed result rather than adding to a saved history.

The tool runs in your browser and does not upload your input. Save the result before refreshing or leaving the page. If other people need to use the same outcome, share your saved copy rather than asking them to generate another independent result.

Frequently asked questions

Can the d100 output be zero?

No. A 100-sided roll here returns 1 through 100 inclusive.

Can I roll different die sizes together?

One batch uses a single side count. Roll and save each die type separately if your game combines sizes.

Does the total include bonuses or penalties?

No. The total is the sum of the raw dice. Apply your game’s modifiers afterward.

What should I check in the worked example?

Every output lies in 1–100. There is no 00 label in the tool’s raw output.
