Random Group Generator With Names
Paste a list of names, choose group count or size, and split it into fully random or balanced groups for classrooms, teams, workshops, and events.
Tip: paste one person per line for the cleanest result. This random group generator works directly in your browser, so your list stays on your device.
Why Use This Random Group Generator With Names?
Fair & Unbiased
We use the Fisher-Yates shuffle algorithm, a proven method for unbiased randomization. This ensures every person has an equal and fair chance of being in any group.
Easy & Fast
Paste your list, choose your settings, and generate groups instantly. The tool stays responsive even with longer name lists.
Privacy-Focused
All group generation happens directly in your browser, so the names you paste are not stored on our servers.
Balanced Teams
The Balanced Groups option keeps team sizes close when equal participation time or limited resources matter.
How to Split a List Into Random Groups
- Enter your names: Paste one name per line into the text box.
- Select your method: Choose whether you want a number of groups or a target group size.
- Ensure fairness: Turn on Balanced Groups when even team sizes matter.
- Generate and share: Run the tool once, then copy or share the results immediately.
How the Grouping Algorithm Actually Works
Most group generators treat their algorithm as a black box. We think you should know exactly what happens to your names, so here is the real process this tool runs every time you click Generate.
Step 1 — Shuffle (Fisher-Yates)
Your pasted list is first shuffled using the Fisher-Yates algorithm, the standard unbiased shuffle used in statistical sampling. Every name has an equal probability of landing in every position, so no name is favored or penalized by its place in your original list.
Step 2 — Round-Robin Distribution
The shuffled names are then dealt into groups one at a time, round-robin style: the first name goes to Group 1, the second to Group 2, and so on, wrapping back to Group 1 after the last group. This is the same dealing method a card dealer uses, and it has one important property — group sizes can never differ by more than one person, no matter how many names you paste.
Random vs Balanced: What Actually Differs
Here is something most users never realize about this tool: the Random and Balanced options produce identical group sizes. Both modes run the same shuffle and the same round-robin deal. Balanced mode adds an extra equalization pass, but because round-robin already keeps every group within one person of the others, that pass has nothing to correct. The only thing that changes between clicks is which names land in which group — the sizes stay even either way. Pick Balanced when you want the evenness guaranteed explicitly; pick Random when you only care that the assignment is unpredictable.
| Names pasted | Groups | Resulting group sizes | What happened |
|---|---|---|---|
| 24 | 4 | 6, 6, 6, 6 | Even split — every group identical in size |
| 25 | 4 | 7, 6, 6, 6 | One group takes the extra person |
| 28 | 5 | 6, 6, 6, 5, 5 | First three groups get the extra names |
| 30 | 6 | 5, 5, 5, 5, 5, 5 | Even split |
| 31 | 6 | 6, 5, 5, 5, 5, 5 | One extra person tips one group to 6 |
| 23 | 5 | 5, 5, 5, 4, 4 | Odd class size — three groups carry the extra |
The pattern is deterministic: with n names and k groups, the first n mod k groups receive one extra person and every group receives at least floor(n/k). You can predict the sizes before you click — only the name assignments are random.
Real Examples: The One-Person Boundary Effect
The most useful thing to know about group sizes is how sensitive they are to a single name. Compare two near-identical classes:
30 students, 6 groups: the deal comes out 5-5-5-5-5-5. Six perfectly even teams, no complaints, no negotiation.
31 students, 6 groups: one group becomes 6 while the other five stay at 5. That single extra student — a late addition, an absent student returning — flips one team from "equal" to "largest." This is not a flaw; it is the mathematical reality of dividing 31 by 6. Knowing this lets you decide in advance whether to form a sixth group of 6, pull a student into a helper role, or absorb the imbalance.
Walkthrough: 12 Names Into 3 Groups
Here is exactly what happens when you paste twelve names and ask for three groups. The paste order is your input; the shuffle randomizes it; round-robin deals it out.
- You paste: Alex, Bella, Chen, Diego, Emma, Finn, Grace, Hugo, Iris, Jack, Kate, Leo (one per line).
- You set: 3 groups, any mode — sizes will be 4-4-4 because 12 divides evenly by 3.
- The tool shuffles the list (one possible outcome): Emma, Leo, Chen, Grace, Alex, Jack, Iris, Diego, Kate, Bella, Hugo, Finn.
- Round-robin deals:
- Group 1 ← Emma, Grace, Iris, Bella (positions 1, 4, 7, 10)
- Group 2 ← Leo, Alex, Diego, Hugo (positions 2, 5, 8, 11)
- Group 3 ← Chen, Jack, Kate, Finn (positions 3, 6, 9, 12)
- Result: three groups of 4. Click Generate again and the names reshuffle — the sizes stay 4-4-4, but every group's roster changes.
The walkthrough above uses a fixed example so you can follow the math. When you run the tool yourself, the shuffle is freshly random each click — but the sizes follow the exact pattern in the table above every single time.
Popular Use Cases
For Teachers
Create random student groups for classroom projects, presentations, discussions, and partner rotation. Need a teacher-focused setup? Open the classroom page. Not sure which method to use? Read Balanced Groups vs Random Groups.
For Coaches
Form balanced practice teams quickly while keeping the process easy to explain to players.
For Team Building

Common Use Cases
This random group generator works for any situation where you need to split a list of names into fair teams. Here are the most common scenarios.
Teacher Classroom Grouping
Teachers use this tool to create student groups for classroom discussions, project teams, partner rotations, and lab activities. Random assignment eliminates the perception of teacher bias and ensures every student works with different classmates over time. For a deeper guide, read How to Split Students Into Groups.
Corporate Team Building
Workshop facilitators and HR teams use random groups to break employees into discussion circles, problem-solving teams, or activity stations. Random assignment prevents cliques and encourages cross-department interaction. See Team Building Group Generator for specific activities.
Online Events and Virtual Meetings
For Zoom breakout rooms, virtual workshops, or online classes, this tool creates fair groups in seconds. Paste participant names, choose the number of breakout rooms, and share the results. Works on any device without downloads or sign-ups.
Frequently Asked Questions
How do I use this random group generator with names?
Paste one name per line, choose the number of groups or target size, and click generate to split the list instantly.
Can I make balanced groups instead of fully random groups?
Yes. Turn on Balanced Groups when you want team sizes to stay as even as possible.
Does this tool work for classrooms and teachers?
Yes. It is useful for student groups, partner work, table assignments, and short classroom activities.
Is my list of names stored anywhere?
No. Grouping happens in your browser, so the names you paste are not stored by us.
Can I use this tool for teams, workshops, or events?
Yes. The same workflow works for sports practice teams, workshops, office groups, and community events.
