Random Team Generator
Split a list of names into balanced random teams by choosing either the number of teams or the number of people per team.
Build Your Teams
Enter participants, choose how teams should be sized, and optionally add custom team names.
Blank lines are ignored. Participants are shuffled before being distributed across teams.
Teams will be kept as even as possible.
The generator will calculate an appropriate number of teams from this target size.
Enter one team name per line. Missing names automatically become Team 1, Team 2, and so on.

How the Random Team Generator Works
Add Participants
Enter each person on a separate line.
Choose Team Size
Set either the number of teams or the preferred number of people per team.
Generate Teams
Participants are shuffled and distributed as evenly as possible.
Use Number of Teams When the Group Count Is Fixed
Choose Number of Teams when an activity requires a specific number of groups.
For example, 24 participants divided into four teams produces four teams of six.
Use People per Team for a Preferred Group Size
Choose People per Team when the approximate group size matters more than the exact number of teams.
The generator calculates the required team count and then balances participants across those teams.
Duplicate Entries Count as Separate Participants
When duplicate entries are allowed, every line represents an individual position in the team assignment.
Turn off duplicate entries if the same participant was accidentally entered more than once.
If two different people genuinely share a name, use identifiers such as Alex M. and Alex T..
Random Teams Are Not Skill-Balanced Teams
The generator balances the number of participants in each team, not ability, experience, position or skill.
Competitive activities that require seeded or ability-balanced teams may need additional manual adjustment.
Popular Uses for Random Teams
Classroom Groups
Divide students into discussion, project or activity teams.
Sports
Create informal teams for football, basketball or training activities.
Games
Split players into random teams for parties, events or game nights.
Workshops
Create breakout teams for exercises and collaborative sessions.
Work Activities
Randomly assign participants to temporary groups or challenges.
Study Groups
Divide a class or study session into smaller collaborative teams.
Private Browser-Based Team Generation
Normal team generation happens directly inside your browser.
- Your participant list does not need to be uploaded to SwiftVecto.
- Random shuffling and team assignment happen locally in the browser.
- Generated teams remain part of the current page session.
- No account is required.
Review Teams When Special Requirements Apply
Random allocation is useful for general activities, but it does not account for accessibility, safeguarding, specialist needs, ability or interpersonal considerations.
Review generated teams before using them where those factors are important.

How to Use the Random Team Generator
Use the SwiftVecto Random Team Generator to divide a list of people into random teams. Choose either how many teams you want or how many people should be placed in each team, then generate balanced groups instantly.
Overview
The Random Team Generator securely shuffles the supplied names in the browser and distributes them across teams as evenly as possible. You can choose the number of teams directly or choose a target number of people per team. When the total number of people does not divide evenly, the generator spreads the remaining participants across teams so the size difference is kept as small as possible. The generated teams can be reshuffled, copied and regenerated without uploading the list to the server.

Helpful Tips
- Use one participant per line.
- Use identifiers when two different people genuinely share the same name.
- Turn duplicate handling off when repeated entries were added accidentally.
- Use Number of Teams when an activity requires a fixed number of groups.
- Use People per Team when you care more about approximate group size.
- If the participant count does not divide evenly, some teams may contain one more person than others.
- A difference of one participant between teams is normally the most balanced possible result.
- Custom team names are useful for colours, houses, departments or activity stations.
- Regenerating changes the assignment while keeping the same configuration.
- For skills-based or ability-balanced teams, a purely random generator may not be appropriate.
- Do not use random team assignment for decisions that require consideration of safeguarding, accessibility or specialist needs.

Worked Examples
The following examples demonstrate how this tool can be used in realistic scenarios.
20 People Into 4 Teams
Enter 20 names, choose Number of Teams and set the value to 4. The generator creates four teams containing five people each.
22 People Into 4 Teams
With 22 participants and four teams, the most balanced distribution is two teams of six and two teams of five.
Teams of About 5 People
Choose People per Team and enter 5. With 23 participants, the generator determines an appropriate number of teams and distributes participants as evenly as possible.
Two Sports Teams
Enter all players and choose two teams. The shuffled participants are distributed between Team 1 and Team 2 as evenly as possible.
Common Mistakes
Avoid these common mistakes to achieve the most accurate results.
- Entering several people on the same line.
- Leaving accidental duplicate names in the source list.
- Requesting more teams than there are participants.
- Setting people per team to zero.
- Expecting every team to have exactly the same size when the participant count is not divisible evenly.
- Assuming random teams are automatically balanced by skill or ability.
- Using only first names when multiple participants share the same name.
- Expecting regeneration to preserve previous team assignments.
- Using random grouping where specific accessibility or safeguarding requirements need manual consideration.

Frequently Asked Questions
What is a Random Team Generator?
A Random Team Generator takes a list of participants and distributes them randomly across teams.
Can I choose how many teams to create?
Yes. Choose Number of Teams and enter the required team count.
Can I choose how many people should be in each team?
Yes. Choose People per Team and enter the preferred group size.
What happens if the teams cannot be perfectly equal?
Participants are distributed as evenly as possible, usually resulting in a maximum difference of one person between team sizes.
Can I regenerate the teams?
Yes. You can reshuffle the same participants and generate a fresh team arrangement.
Can I use custom team names?
Yes. The interface can support custom names such as Red Team, Blue Team, Lions or Tigers.
What happens if I do not enter team names?
Automatic labels such as Team 1, Team 2 and Team 3 can be used.
Can I use this for students?
Yes. Random classroom group creation is one of the common uses for the tool.
Can I use this for sports teams?
Yes for informal random teams. If teams need to be balanced by ability, position or experience, additional manual adjustment may be required.
Can duplicate names be removed?
Yes. Duplicate handling can be disabled so repeated entries count only once.
What if two different people have the same name?
Give them distinguishable labels such as Alex M. and Alex T. so both remain separate participants.
Can I create one-person teams?
The configuration may allow this where appropriate, although teams normally contain at least two participants.
Can I create more teams than participants?
No. Empty teams are not useful, so the number of teams should not exceed the number of active participants.
Does random mean teams are equally skilled?
No. Random assignment balances participant counts, not skill, experience or ability.
Does SwiftVecto upload my participant list?
The Random Team Generator is designed to perform normal team generation directly inside your browser.
Is the Random Team Generator free?
Yes. SwiftVecto provides the Random Team Generator as a free browser-based utility.
Things to Know
- The Random Team Generator is designed as a browser-only interactive tool.
- No queue processing is required.
- No file upload is required.
- Participants should be securely shuffled before team assignment.
- Team sizes should differ by no more than one person where mathematically possible.
- Number of Teams and People per Team should be treated as separate sizing modes.
- Duplicate handling should be case-insensitive while preserving the first original spelling.
- Custom team names should fall back to automatic labels where insufficient names are supplied.
- The JavaScript module should export init() so SwiftVecto can lazy-load it only when this tool is opened.
Disclaimer
The Random Team Generator balances participant counts rather than skills, abilities or experience.
Users should review generated teams where accessibility, safeguarding or specialist requirements apply.
Random assignment may not be appropriate for competitive situations that require seeded or ranked teams.
Users remain responsible for deciding whether random allocation is suitable for their activity.
