Random number generator guide

How to use the Random Number Generator

The Random Number Generator helps you pick one number or build a short list of random integers. Set the range, choose how many results you need, then add unique results, exclusions, sorting, and copy when the task needs a cleaner output.

Open the random number generator

Quick start

  1. Enter the minimum and maximum whole numbers for the range.
  2. Enter Quantity to choose how many random numbers to generate.
  3. Turn on Unique results if every number in the list must be different.
  4. Add excluded numbers when certain values should not appear.
  5. Press Generate numbers, then copy the results or compare recent results.

Choosing the range

The minimum and maximum values are inclusive. If you enter 1 and 10, the generator can return 1, 10, or any whole number between them. The minimum must be less than or equal to the maximum.

Use a small range when you want a simple pick, such as a number from 1 to 6 or 1 to 10. Use a larger range when you need sample values, classroom examples, or a numbered list with more possible outcomes.

Unique results and duplicates

When duplicates are allowed, the same number can appear more than once. That is useful when each draw should behave like a fresh independent pick.

When Unique results is turned on, each number can appear only once in the generated list. For example, if the range is 1 to 5 and you ask for 5 unique numbers, the result will include every available number once.

Exclusions and sorting

Exclusions are useful when a numbered option is unavailable. Enter excluded numbers separated by commas, spaces, or semicolons, such as 7, 13, 24. Numbers outside the selected range are ignored.

Sort results changes the display order from draw order to low-to-high order. This is useful when you plan to copy the list into notes, a worksheet, or a message.

Common examples

1 to 10, quantity 1 Pick one number from a short numbered list.
1 to 100, quantity 5 Generate a small list of random sample values.
1 to 50, unique sorted Build a clean list with no repeated numbers.
1 to 20, exclude 7 and 13 Skip numbers that should not appear in the result.

Examples from the random number generator

Pick one number 1 to 10

One random integer from 1 through 10

Generate a list 5 numbers from 1 to 100

Five random integers, duplicates allowed

Unique sorted numbers 6 unique numbers from 1 to 50

A sorted list with no repeated numbers

Everyday randomness limits

This tool is designed for ordinary web utility tasks: practice picks, classroom examples, simple games, quick decisions, and sample data. It should not be used for passwords, gambling, legal drawings, security decisions, or any process that needs audited randomness.

History, privacy, and copying

Recent random results stay visible in the page while you work. This is useful when you want to compare a few attempts without writing each one down. The history is kept only in the current browser tab and is not sent to a server.

Copy results copies the current list exactly as displayed, separated by commas, so you can paste it into notes, homework, a message, or another document.
