2.6–3.0 m (8.5–9.8 ft)
Ground-level soft play, ball pit, role-play and low crawl features
1–6 years
Protect parent sightlines and keep service access outside the play route.
3.0–3.5 m (9.8–11.5 ft)
Single-level or compact two-level arrangement
1–8 years
Check slide path, overhead services and padding build-up.
3.5–4.0 m (11.5–13.1 ft)
Two-level frame with short slide and obstacle route
2–12 years
Separate fast circulation from the toddler zone.
4.0–4.72 m (13.1–15.5 ft)
Two levels with more generous route and landmark space
2–12 years
Do not assume a third level fits; roof services and top clearance still govern.
4.72–5.0 m (15.5–16.4 ft)
Three-level candidate subject to project engineering
2–12 years
Check the full vertical build-up, exit path and site authority requirements.
Above 5.0 m (above 16.4 ft)
Vertical landmarks, taller tubes or rope features become design options
3–12 years
Compare the extra structure against throughput, supervision and cost.
