Random Number Generator 1-4
Generate a random integer from 1 to 4, with both ends included.
This page returns integers from 1 to 4 — each number appears 25% of the time. The range is fixed so you can generate again without re-entering the bounds.
Typical use: picking a player from four, choosing a quadrant, or a 1-in-4 draw. If you need a different range, the fields above are editable; the URL stays on this page and nothing is submitted anywhere.
How to use it
- Press generate — the range is already set to 1-4.
- Turn on no-repeats if you are drawing several winners from the same set.
- Copy the result, or keep generating; each result is independent.
Why the range stops at 4
Four divides cleanly into 100, which makes it the easiest range to sanity-check by generating a few hundred values. With 4 possible values, the chance of any specific number coming up is each number appears 25% of the time.
Generating with a narrow range is not the same as generating a wide range and rejecting out-of-range values. Filtering like that biases the result towards whatever is left; this tool draws directly from the range you set, using rejection sampling on the raw random bits.

Frequently asked questions
Can I use 1-4 to simulate a d4?
It gives the same distribution as a four-sided die. The dice roller tool adds multiple dice and totals if you need something closer to a tabletop session.
Is 1 or 4 more likely than the middle values?
No. Each of the 4 values has an identical probability. If you generate a few hundred results, the counts should converge towards equal — small samples always look lumpy.
Can I generate more than one number at once?
Yes. Set the count above; leave no-repeats off if duplicates are acceptable, turn it on if you are drawing distinct winners.
