How to use the even number generator
- Set the range. If an end is not even, the draw steps inward to the nearest even value.
- Choose how many even numbers you need, and whether repeats are allowed.
- Press Generate even numbers, then copy or download the set.
How many even numbers a range holds
Exactly half of any long run of whole numbers is even, so the pool behind each draw is easy to predict. These are the counts for the ranges people set most.
| Range | Even numbers in it | First | Last |
|---|---|---|---|
| 1 to 100 | 50 | 2 | 100 |
| 1 to 1000 | 500 | 2 | 1000 |
| 0 to 50 | 26 | 0 | 50 |
| 2 to 20 | 10 | 2 | 20 |
| -100 to 100 | 101 | -100 | 100 |
Zero counts as even, which is why 0 to 50 holds 26 evens rather than 25, and why a range that straddles zero picks up one extra.
The arithmetic of even numbers
Parity follows fixed rules, which is what makes even numbers useful in teaching and in checks. Whatever two numbers this generator hands you, these results always hold.
| Operation | Result |
|---|---|
| even + even | always even |
| even + odd | always odd |
| odd + odd | always even |
| even times any whole number | always even |
| odd times odd | always odd |
A quick classroom exercise: draw two evens with this tool, add them, and confirm the first row. Draw an even and an odd from the odd number generator and confirm the second.
Repeats arrive faster in a filtered pool
Filtering to evens halves the pool, and a smaller pool means duplicates appear sooner. Drawing evens from 1 to 100 leaves 50 possible values, and the chance of at least one repeat climbs quickly: 19 percent by 5 draws, 53 percent by 9, and 99 percent by 20. When every value must differ, tick no repeats, which caps the draw at the 50 evens the range holds.
How this compares with other generators
Most general purpose generators have no parity control at all, leaving you to draw twice as many numbers and delete the odd ones by hand, and among the big names only calculator.net offers an even and odd option inside its comprehensive tool. This page draws from the even values directly, stepping through the range two at a time, so results are uniform across the evens with nothing to filter afterwards.

Frequently asked questions
How are even numbers chosen
The tool finds every even number in your range, then draws from that set with the browser cryptographic random source. Each even value has the same chance.
Can I get even numbers with no repeats
Yes. Tick no repeats and every value in the set is different. The count is capped at how many even numbers your range holds.
Does the range have to start on an even number
No. Type any whole numbers. If an end is not even, the tool moves inward to the nearest even value inside the range.
Can the range include negatives
Yes. A range such as minus 100 to 100 works, and negative even numbers are drawn with the same chance as positive ones.
Is it free
Yes, free and with no sign up. Every draw runs in your browser and nothing you enter leaves your device.
