How to define a random number range correctly
Choose the smallest and largest allowed integers, not the number of possible outcomes. A range from 1 to 20 includes 1, 20, and every integer between them.
Check whether repeated values are acceptable
Several independent results may contain duplicates. That is correct for repeated draws with replacement. If every participant must appear only once, use a shuffled list or a wheel with winner exclusion instead.
- Use a range that matches the actual item numbers.
- Remember that both endpoints are eligible results.
- Generate only the quantity needed for the current task.
- Record a result before generating a replacement.
Good uses and important limits
The generator is suitable for everyday selections, games, samples, and development data. It is not a certified drawing system and does not create an external audit record, so regulated lotteries or high-stakes selections need a process designed for those requirements.
Frequently asked questions
Can I generate more than one number?
Yes. Set the count to produce one or several integers from the chosen minimum and maximum.
Are both range limits included?
Yes. The minimum and maximum can both appear in the result.
How are the numbers generated?
The tool uses the browser Web Crypto API and performs the generation locally on your device.
Are results sent to a server?
No. The selected range and generated values stay in the browser while you use the tool.
