Random Number Generator

Pick a minimum and maximum value and generate a random whole number in that range. Each click produces a new integer in the inclusive interval.

Enter integer values and make sure the minimum is not greater than the maximum.

How random numbers are generated

This calculator picks a random integer between your minimum and maximum values, including both endpoints.

Random selection is useful for simulations, picking winners, sampling data, or creating quick test inputs.

The generator uses a uniform distribution, meaning each integer in the range has the same chance of appearing.

If you need reproducible sequences, use a fixed seed in code. This tool is designed for quick, simple randomness.
