Formula and calculation method
Each die is an independent uniform integer from 1 to the number of sides.
Use consistent units for all comparable inputs. The displayed result is rounded; arithmetic is performed with the full available numeric precision. Check your source measurements before relying on the result.
How to use dice roller
- Set Dice count. The example below uses 2.
- Set Sides per die. The example below uses 6.
- Select Calculate to update the result. Reset restores the illustrated inputs. Copy, print or download your own result if you need a record.
Worked example
This tool produces a fresh random result on each calculation. With the example settings below, every generated value follows the selected range or alphabet. No fixed example result is presented as your actual output.

Factors affecting your result
Use consistent units for all comparable inputs. The displayed result is rounded; arithmetic is performed with the full available numeric precision. Check your source measurements before relying on the result.
Changing dice count changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
