Set your minimum and maximum values
Use the full range you want the generator to work inside. The tool will normalize the bounds if they are entered in reverse order.

Random Number Generator
Generate one or many random values inside a custom range, choose unique mode, and switch between integers and decimals in seconds.
Generator controls
Generated numbers
The result panel shows the generated values plus a quick summary so you can sanity-check the range before you copy them.
What this generator is good for
It works best for fast one-off numbers and short lists where you want the result immediately instead of configuring a heavier tool.
- Raffles, classroom prompts, and game mechanics
- Sampling IDs, test values, and lightweight placeholders
- Decision support when you want a bounded random range
How to use the random number generator
Set the lower and upper bounds first, then decide whether the result should be a single value or a larger list.
Choose integers or decimals
Use integers for dice-style draws, positions, or counts. Switch to decimals when you need ranges for samples, percentages, or lightweight mock data.
Decide how many values to return
Increase the count when you need a short batch instead of a single draw, then optionally sort or restrict the output to unique integers.
Example scenarios
These setups cover the most common everyday number-generation cases.
Simple raffle number
Generate one whole number between 1 and 100.
Sample setup
- Minimum
- 1
- Maximum
- 100
- Count
- 1
- Format
- Integers
Result: One random integer is returned.
Unique shortlist draw
Generate five unique integer positions between 1 and 20.
Sample setup
- Minimum
- 1
- Maximum
- 20
- Count
- 5
- Unique values
- On
Result: Five different integers are returned with no repeats.
