About Random Group Generator

Welcome to the Random Group Generator, a free online tool designed to help you create fair, balanced random groups from any list of names. Whether you are a teacher forming study groups, a team leader organizing project teams, an event coordinator creating competition brackets, or anyone who needs to divide people into groups randomly, this tool makes the process quick, easy, and completely fair.

At a Glance

Random Group Generator splits a pasted list of names into random groups, either by the number of groups or by people per group. Results show as color-coded cards you can copy, reshuffle or reveal with a wheel.

Random Group Generator: features at a glance
Feature	What you get	Good for
Two grouping modes	Group by size (people per group) or by number of groups. Enter one name per line, and a counter shows how many names you have.	Classes, workshops and events with a known team size or count
Balanced sizes	When grouping by count, group sizes differ by at most one person.	Fair teams when the list does not divide evenly
Fisher-Yates shuffle	Names are shuffled with the Fisher-Yates algorithm, so every arrangement is equally likely. Shuffle Again gives a fresh arrangement.	Draws that need to be unbiased and repeatable on demand
Spinning wheel reveal	Tick the wheel option and a wheel places each name into its group one spin at a time. Press Show all to skip it.	Live draws on a projector in class
Mix two lists	Put one list in the first box and another in the second, and each group gets a proportional share of both.	Spreading boys and girls, or beginners and experts, across groups
Copy and saved names	Groups are lettered A, B, C with numbered members. Copy one group or all, and the list is kept in your browser.	Sharing groups by email or chat and returning to the same list

Why Use a Random Group Generator?

Random group assignment eliminates bias and ensures fairness in team formation. When humans manually create groups, they often unconsciously favor certain combinations or avoid others. A random generator treats everyone equally, giving each person an equal chance of being placed in any group.

Many teachers find that students accept random group assignment as fair and are willing to work together effectively.

Key Features

🎲

True Randomization

Uses the Fisher-Yates shuffle algorithm to ensure completely unbiased, mathematically random group assignments.

⚖

Balanced Distribution

When creating groups by count, members are distributed as evenly as possible with at most a one-person difference between groups.

💾

Saves Your Input

Your name list is automatically saved in your browser, so you can return later without re-entering names.

📋

Easy Copy and Share

One-click copy buttons for individual groups or all groups at once. Perfect for sharing via email or messaging apps.

Two Flexible Grouping Modes

1. Group by Size

Choose this mode when you know how many people you want in each group. For example, if you have 20 students and want groups of 4, you will get 5 groups with 4 members each. If the numbers do not divide evenly, some groups will have one extra or one fewer member.

2. Group by Number of Groups

Choose this mode when you know how many total groups you need. For example, if you have 15 people and need 4 teams, the tool will create 4 groups with either 3 or 4 members each, distributed as evenly as possible.

Tip: If you need exactly equal groups and your total does not divide evenly, consider adding or removing a few names, or accept that some groups will have one extra member.

Common Use Cases

Forming the groups is usually only half the lesson. To call on students one at a time within those groups — without asking the same person twice — paste the same list into the Random Name Picker and turn on No repeats.

How to Use This Tool

Enter your names: Type or paste the names of people you want to group in the text area. Enter one name per line. You can include first names only, full names, or any identifiers that work for your situation.
Choose your grouping method: Select either "By Group Size" if you want to specify how many members per group, or "By Number of Groups" if you want to specify the total number of groups.
Enter your number: Based on your chosen method, enter either the desired group size or the total number of groups you want to create.
Generate groups: Click the "Generate Random Groups" button to see your randomly assigned groups displayed in colorful, easy-to-read cards.
Copy or reshuffle: Use the copy buttons to save your results, or click "Shuffle Again" to generate a new random arrangement if you want different groups.

Understanding the Results

After generating groups, you will see:

Statistics Summary: Shows the total number of members, groups created, and the size range of groups
Color-Coded Group Cards: Each group is displayed in a distinct color for easy visual identification
Group Letters: Groups are labeled A, B, C, etc. for easy reference
Member Lists: Each card shows all members assigned to that group with numbered positions
Copy Buttons: Individual copy buttons for each group, plus a "Copy All" button for the complete results

Tips for Best Results

Clean your list: Make sure each name is on its own line and remove any blank lines or duplicates
Be consistent: Use consistent naming (all first names, or all full names) for a cleaner display
Check the count: The name counter below the input area shows how many names you have entered
Reshuffle freely: Click "Shuffle Again" as many times as you like until you get an arrangement you are satisfied with
Use presets: Try the preset examples to quickly see how different grouping options work

Privacy and Data

Your name list is stored only in your browser using local storage. No data is sent to our servers or stored in any database. When you close your browser or clear your browsing data, the saved names are removed. This ensures your data remains private and under your control.

Frequently Asked Questions

Is there a spinning wheel for dividing groups?

Yes. Tick "Reveal the groups with a spinning wheel" before you generate. The groups are drawn at random on our server first, then the wheel places each name into its group one spin at a time, so you can show the draw live on a projector. Press Show all to skip the animation.

Can I split boys and girls evenly across groups?

Yes. Tick "Mix two lists evenly", put one list (for example the boys) in the first box and the other (the girls) in the second box. Each group then gets a share of both lists in proportion to its size, so boys and girls are spread as evenly as the numbers allow (with 1 girl and 9 boys, only one group can have a girl). It works with any two categories, such as beginners and experienced players.

Is the randomization truly random?

Yes, the tool uses Python's random.shuffle() function which implements the Fisher-Yates shuffle algorithm. This is a well-established algorithm that guarantees each possible permutation has an equal probability of occurring.

What happens if my number does not divide evenly?

The tool handles uneven divisions gracefully. When grouping by count, extra members are distributed one at a time to the first groups. When grouping by size, the last group may have fewer members than the specified size.

Can I use this for very large groups?

Yes, the tool can handle lists of hundreds of names. However, for very large lists (over 200 names), the visual display may become lengthy. The copy function works well regardless of list size.

Why did I get the same groups when I shuffled again?

Each shuffle is independent and random. With small lists, there is a higher probability of similar arrangements occurring by chance. With larger lists, repeated arrangements are extremely unlikely.

Can I save my groups permanently?

Use the "Copy All Groups" button to copy the results to your clipboard, then paste them into a document, email, or note-taking app for permanent storage.
