What fall height can playground safety mats and tiles protect against?

Critical fall height is the maximum distance from which a child can fall without sustaining a life-threatening head injury. This measurement is the cornerstone of playground safety design and is determined through rigorous impact testing per BS EN 1177.

During testing, an instrumented anthropomorphic dummy is dropped from a measured height onto the tile surface over a concrete base. Sensors record the deceleration forces experienced by the dummy's head upon impact. The Head Injury Criterion (HIC) evaluates the severity of that impact by measuring peak acceleration and duration. A result exceeding 1000 indicates unacceptable head trauma risk and the tile fails certification; a result of 1000 or below means the surface provides adequate protection at that height.

Typical fall heights align with common play equipment: up to 1 metre suits play houses and low balance beams; up to 1.5 metres covers slides and seesaws; up to 2 metres protects against falls from rope nets and climbing frames; up to 3 metres is required for tall towers and the highest climbing structures. The height you require depends on the equipment in your space and the age range using it.

Manufacturer certification is decisive. Do not estimate based on thickness alone; always verify the certified fall height figure from an independent test report. WARCO publishes transparent, verifiable certification data for all products. When in doubt about which product suits your application, choose the higher category—it offers a safety margin. If two products protect to the same height, the heavier or thicker option will deliver a longer service life before deformation becomes visible.

Only install tiles that carry BS EN 1177 certification from a recognised notified body. Unverified claims or products lacking formal test documentation put users at risk.
