Variable-Size Group Splitter
Split a list into groups of variable size.
The Variable-Size Group Splitter divides your list into random groups whose sizes vary within a minimum and maximum you set. It's useful when you want natural-feeling clusters — breakout rooms, discussion pods, or rotating stations — rather than rigidly equal teams. Set your range, click split, and everyone is placed without anyone being left out.

Frequently asked questions
How is this different from the Team Divider?
The Team Divider makes equal-sized groups. The Variable-Size Splitter lets group sizes vary within a range you choose.
Will it leave anyone out?
No. A small leftover group is merged into the previous group so everyone is included.
Is the grouping random?
Yes. The list is shuffled with your browser's Web Crypto API for an unbiased, cryptographically sound split.
Are my names sent to a server?
No. The splitter runs entirely in your browser and works offline, so your list stays on your device.

- Picking a group-size range for the activity, not the headcount
Most people set a group-size range by dividing their headcount and guessing. Here's how to pick min and max based on what the activity actually needs — with real ranges for book clubs, hackathons, classroom stations, and party games.
- Splitting a list into groups that don't all have to match
Not every activity needs equal-sized teams — sometimes you want groups of three here, five there, and no awkward leftover pair. Here's how a variable-size group splitter handles the range instead of forcing one fixed number.
- Picking random teams without starting a fight
Randomising teams sounds easy: shuffle, deal, done. In practice you need to think about balance, locked groups, varying sizes, and the friend who always ends up on the same side. Here's how we handle it.
