The right team building activity depends heavily on how many people you’re bringing together. A format that works brilliantly for 20 people can fall flat with 100, and vice versa. Here’s how to match the activity to your group size.
Groups of around 20
Smaller groups suit more personal, conversation-driven formats where everyone gets real airtime.
- The Belbin Experience – team development based on Belbin team roles, well suited to a single team or department getting to know how they work together.
- Murder Mystery – an immersive format where a smaller group means everyone gets a proper character and role to play.
- Dublin Bay Sail – the vessel is licensed for up to 12 passengers, so this suits a smaller group or splits a group of 20 into two sailings.
Groups of around 50
Mid-sized groups work well with activities that can run several teams in parallel, keeping the energy competitive without losing structure.
- Celtic Games – traditional outdoor Irish games split naturally into multiple teams.
- Code Breaker Treasure Hunt – teams race independently around Dublin’s landmarks, so it scales well across several groups.
- The Big Quiz – built for groups of 20 to 100, with a host, scoreboard and buzzers.
Groups of around 100
Larger groups need an activity designed from the ground up for scale, usually with multiple zones or stations running at once.
- WeGo Worlds Challenge – built around up to six themed activity zones with a group finale, designed for large-scale days.
- It’s a Knockout – a tournament format that naturally accommodates many teams competing side by side.
- Old School Sports Day – classic sports day games that scale easily across a large group.
