Official Random Number Generator

Generate An Instant Random Number Between Two Numbers Of Your Choice.

Trying to think of a number but just can’t come up with anything? Demonstrating probability for a classroom? Need to pull a random number from a hat for a raffle? You’ve come to the right place! Our random number generator will give you just that—a random number. 

A random number is a number chosen by chance from a set range. The beauty of random numbers is that you can’t predict what number you’ll get. Even if you choose 2 the first time, 4 the second, and 6 the third, any perceived pattern is totally random! The fourth time you choose it could be 19 or 100. It’s all up to chance. 

Our generator will provide a random number between the two numbers of your choice. Just enter a lower limit number and an upper limit number and click ENTER.  Your random number will be generated and appear in the box.

Enter an upper limit:

Why You Should Use a Random Number Generator

Now, if you’re trying to come up with a list of random numbers yourself, you probably will find a pattern. Even subconsciously, the human mind is conditioned to look for and create things in a pattern or sequence. Unfortunately, this could negatively impact math problems you’re working on or activities you have planned. 

To make sure it stays up to chance and that you don’t have any influence over this choice, we’ve created this handy random number generator that can select a number for you. It’s simple to use. Just put in two numbers and the random number generator will give you an integer in between them.  

How To Use a Random Number Generator

The random number generator recognizes whole numbers and negative numbers. It does not recognize decimals, fractions, or equations. If you insert a percent symbol, the symbol will not carry over into the random number box.

  1. Start by entering a number of your choice in the Lower Limit box.
  2. Then input another number of your choice in the Upper Limit box.
  3. Once you have your two numbers, click Enter.
  4. Your random number will appear in the Random Number box.
  5. Keep pressing Enter for a new number every time.
  6. To reset your Lower Limit and Upper Limit numbers, select Clear. 

Working Example

Let’s say you need to pull a random number for a raffle prize. There are thirty people who enter the raffle, and only three people will win. The tickets range from 1 to 150, so the Lower Limit is 1 and the Upper Limit would be 150. Click Enter and the random number generator gives you a 7, 36, and 2.

Raffle participants with the numbers 7, 36, and 2 on their tickets will be the three raffle winners. 

Decimal Trouble

Imagine you are trying to find a number between 2.01 and 2.5. You enter 2.01 as your Lower Limit and 2.5 as your Upper Limit. You click Enter, and you get—a 2? That’s not between your values! Sorry, there are no decimals allowed in this random number generator. However, as long as you’re working within decimals of the same whole number, you could use other whole numbers as your two values, and assign the result after the decimal. 

So if your range is between 2.01 and 2.5, you could enter 1 and 50 in the value boxes. Let’s say it generates the number 25. You could assign that after your decimal, and this would be your result: 2.25
