Which Inflatable Dome Do I Need?

Step 1: Choose your dome size

3m x 3m dome

The 3m x 3m dome is the easiest dome to place at busy venues and smaller pitches. It gives you a clean branded footprint without demanding much space, making it ideal when you need visibility but you are working within tight layout restrictions.

Best for:

• registration points and welcome desks

• compact sampling stations

• sponsor branding points at smaller events

• community events and charity outreach

• merch points where space is limited

If you tend to work at venues where layouts change often, or you regularly deal with tight pitch sizes, 3m x 3m is the practical option.

4m x 4m dome

4m x 4m is the best all-rounder. It has noticeably more usable space than 3m x 3m, but it still remains easy to position at most outdoor events. This is the size most organisations choose when they want a proper branded hub without going fully large format.

Best for:

• activations with a demo table or display counter

• hospitality points with staff space behind the counter

• info hubs at open days and public events

• higher footfall sponsor zones

• touring promotional setups

If you are unsure which dome to choose, 4m x 4m is usually the safest decision.

5m x 5m dome

The 5m x 5m dome is the step up into “proper event hub” territory. It gives you a bigger branded footprint, and better flow when the crowd builds up. This is the size you choose when you want your setup to look more like a destination than a cover point.

Best for:

• hospitality areas and sponsor lounges

• product demos with equipment

• touring merchandise with queue space

• larger activations where footfall is constant

• media points, content areas and meet and greet zones

If your event setup normally includes multiple elements (counter, displays, storage boxes, staff), 5m x 5m makes life easier.

6m x 6m dome

The 6m x 6m dome is maximum presence in the range. This is the size you choose when the event is big, the competition is loud, and the branding has to work from long range as well as up close. It creates a major branded footprint that feels like a headline feature.

Best for:

• major festivals and city-centre activations

• large sponsor areas where branding must dominate

• outdoor hospitality points with multiple staff

• big demo spaces and high-impact product launches

• events where you need a serious branded hub

If you are regularly at major venues or national-scale events, 6m x 6m is the dome that keeps you looking premium.

Quick size guide summary

If you want the simplest way to choose:

• 3m x 3m: compact, tight pitches, fast deployments

• 4m x 4m: best all-rounder for most events

• 5m x 5m: event hub size with more usable space

• 6m x 6m: flagship presence for major venues

Step 2: Do you need sidewalls or not?

Once you have chosen the size, the next decision is whether you want open access or a more enclosed space.

This choice changes how the dome works on site more than anything else.

Domes with sidewalls

Sidewalls give you protection, privacy and control. They create a cleaner interior environment for staff and equipment and they increase the total branded surface area. If you need to store kit inside the dome, protecting equipment from weather, sidewalls are the right choice.

Choose sidewalls if:

• you need protection from wind and weather

• you have equipment, stock or valuables inside

• you want a more controlled customer experience

• you want more branding coverage across the structure

Ideal uses:

• hospitality units

• staff workspaces

• demo zones with electronics or stock

• controlled event environments

• multi-day setups where protection matters

If your setup includes anything you would not leave exposed in a typical gazebo, sidewalls are worth it.

Canopy-only domes (no walls)

Canopy-only domes are designed for open access. People can approach from every side, staff can move quickly, and the whole setup feels welcoming and interactive. This is the best option for high footfall environments where flow matters.

Choose canopy-only if:

• you want easy access from every angle

• you will be interacting with the public all day

• you want the setup to feel open and welcoming

• you need fast staff movement in and out of the space

Ideal uses:

• sampling stations

• sponsor zones

• registration points

• merch points

• front of house welcome areas

If the dome is part of the event experience and you want people to approach freely, canopy-only usually wins.

Final checklist

If you want a fast selection method:

Choose your size:

• need a compact footprint: 3m x 3m

• want the safe all-rounder: 4m x 4m

• building a real branded hub: 5m x 5m

• need maximum presence: 6m x 6m

Then choose your layout:

• high footfall, open access: canopy-only

• protection, privacy, control: with sidewalls

Choosing the right inflatable dome comes down to two things: the footprint you need, and how you want people to use the space. If you want maximum interaction and easy flow, canopy-only is usually the best fit. If you need protection, privacy or a controlled interior environment, sidewalls are the smarter choice.
