About This Calculator
Our 4 Sided Dice Roller is a free online tool for rolling virtual D4 dice. Whether you are playing Dungeons & Dragons, Pathfinder, or any tabletop RPG that uses four-sided dice, this calculator simulates fair random rolls with detailed statistics.
The calculator uses a random number generator to produce values between 1 and 4 for each die. After rolling, you get the total sum of all dice, the average roll value, the minimum and maximum rolls, and a complete list of individual values. The frequency chart shows the distribution of each face value so you can verify fairness or analyze your dice pool.
How to Use
Enter the number of D4 dice you want to roll (1 to 15) and click Roll Dice. Each click generates a completely new random set. The results update instantly with total, average, min, max, individual values, and a color-coded frequency bar chart. The chart has two modes: Frequency (shows how many times each value appeared) and Rolls (shows each individual die value).
D4 Dice in Gaming
The D4, also known as the tetrahedron or four-sided die, is the smallest polyhedral die used in tabletop gaming. It has four equilateral triangle faces and a unique shape that makes it distinct from other dice. D4 dice are essential for damage rolls in many tabletop RPGs — daggers, sickles, and low-level spells often use D4 for damage calculation. They are also used for hit point rolls at character creation and early levels.

Frequently Asked Questions
What is a 4-sided dice roller?
A 4-sided dice roller is a digital tool that simulates rolling D4 dice, commonly used in tabletop role-playing games like DND and Pathfinder. It randomly generates numbers from 1 to 4 for each die and provides totals, averages, and frequency analysis.
Are 4-sided dice fair?
Yes, D4 dice are fair dice. A tetrahedral D4 has four identical equilateral triangle faces, giving each face an equal probability of 25%. Our digital roller uses cryptographically-inspired random number generation to ensure fair results every time.
How many D4 dice can I roll at once?
You can roll up to 15 four-sided dice at once with our calculator. This covers most tabletop gaming scenarios including damage rolls for small weapons in DND and other RPGs.
What games use D4 dice?
D4 dice are widely used in tabletop RPGs including Dungeons & Dragons, Pathfinder, and various indie RPGs. They are commonly used for damage rolls of small weapons like daggers, and for hit point recovery at early levels. Some board games and wargames also use four-sided dice.
How do you read a D4 die?
A D4 die comes in two styles. In the pyramidal style, the number is read at the apex where three faces meet, and the upright number on each face is the result. In the rounded-edge style, the number on the top face is read directly. Our digital roller handles this automatically by generating standard 1-4 values.
Can I share my dice roll results?
Yes, the calculator automatically saves your dice count in the URL, so you can share the link with friends or bookmark it for future gaming sessions. Each click of the Roll Dice button generates a new random set of values.
What is the probability of rolling a specific number on a D4?
Each face of a fair 4-sided die has an equal 25% chance (1/4) of appearing. The probability of rolling any specific number from 1 to 4 is always 25%, regardless of previous rolls, because each roll is an independent event.
How does the frequency chart work?
The frequency chart displays a bar graph showing how many times each value (1 through 4) appeared in your dice roll set. With a large number of dice, the distribution should approach a uniform 25% per value if the dice are fair.
