ASTM F1918 vs EN 1176: which safety standard does your indoor playground need?
A plain-English comparison of the ASTM and EN safety standards that apply to indoor playgrounds, trampoline courts and play surfacing, and when each one applies.
Short answer
Start from the usable floor area and clear ceiling height, allow roughly 2 m² of play area per child to estimate capacity, then split the space into a main structure, a separate toddler zone, party rooms and a parent seating area with clear sightlines to every exit.
Key takeaways
- Measure clear height under beams, sprinklers and ducts, not slab-to-slab.
- Use about 2 m² of play area per child as a first capacity estimate.
- Keep under-3s physically separated from the main structure.
- Parents should be able to see every slide exit from their seats.
Every indoor playground we design starts the same way: a buyer sends a floor plan, a few photos and a rough idea of who the customers will be. The plan decides almost everything else — how many levels fit, how many children you can admit at once, where the toddler area goes and how much the structure will weigh on the floor. This guide walks through the order we work in, so you can prepare a brief that gets you an accurate design and quote on the first round.
What should you measure before asking for a design?
Send a plan with dimensions in metres or feet, and mark these items on it:
- Clear ceiling height — the lowest point under beams, ducts, sprinklers and lights. A two-level structure generally needs at least 2.6 m clear; three levels usually need 4 m or more.
- Columns and fixed obstacles — structural columns can often be wrapped and built into the frame, but we need their exact positions.
- Entrances, emergency exits and fire routes — the play structure must never block them.
- Floor type and load — concrete slab, raised floor or mezzanine. Large structures and ball pits are heavy.
- Windows, toilets, kitchen and reception — these shape where the noisy and quiet zones should go.
How many children can the playground hold?
A practical first estimate for commercial soft play is one child per 2 m² of play area. A 300 m² play zone therefore suits around 150 children at peak. Your local building and fire authority sets the legal occupancy, which also counts accompanying adults and staff, so treat this figure as a design target rather than a permit number.
Capacity is not only floor area. Multi-level structures add play surface on each deck, but they also add walking time between attractions. If the business model depends on timed sessions, a wider single-level layout with more parallel activities can move more children per hour than a tall tower.
Which zones does a commercial playground need?
- Main structure — the multi-level frame with slides, net bridges, obstacles and ball pools. It is the photo on your marketing and usually takes 50–65% of the play area.
- Toddler zone — a separate, low area for under-3s with soft shapes, a small slide and a shallow ball pool. Separate it with a low wall or netting so bigger children cannot run through.
- Feature attractions — a trampoline court, ninja line, interactive wall game or climbing wall gives older children a reason to come back.
- Party rooms — two or three rooms close to the kitchen and away from the entrance. Parties often produce the strongest margin in the business.
- Parent seating and café — position it with direct sightlines to slide exits and the toddler area.
How do you keep circulation and supervision simple?
Children should enter the structure in one obvious place and exit at several points close to the parent area. Avoid dead ends deep inside the frame, keep slide run-outs clear of walkways, and leave staff access routes at each level so a team member can reach any point quickly. Netting should be see-through from the seating area; solid panels belong on the walls facing the building, not facing parents.
What happens after you send the plan?
Our designers return a 2D layout and a 3D render, usually within a few working days, with a component list and quotation. You can then change the theme, swap attractions or move zones until the layout works for your business. Once confirmed, production typically takes 7–30 days depending on size, and every order ships with CAD installation drawings; on-site installers can be arranged on request.

FAQ
What is the minimum ceiling height for an indoor playground?
A single-level toddler area can work under about 2.4 m, but a two-level commercial structure generally needs at least 2.6 m of clear height, and three levels usually need 4 m or more.
How much space do I need for an indoor playground?
Small café or clinic play corners start around 50 m². A neighbourhood playground typically uses 200–500 m², and destination family entertainment centres often exceed 1,000 m².
Can the playground be built around columns?
Yes. Columns are measured on site, wrapped in foam and PVC, and built into the frame so they become part of the structure.
