HOW IT WORKS

Formula and assumptions

Convert maintained loose-fill depth to initial installation depth using settlement, then apply separate ordering waste and the reference fall-height limit.

The entered rectangle represents the full equipment use zone.
The entered depth is maintained depth; settlement determines initial installation depth for non-rubber loose fill. Shredded rubber is not given a compression multiplier.

FIELD CHECK

Before you order

The entered maintained depth is converted to a larger initial installation depth using a separate settlement percentage; an over-limit fall height blocks the purchase estimate.

Worked example

Example: with use-zone length 30 ft, use-zone width 20 ft, equipment fall height 6 ft, loose-fill material Wood chips, the playground surfacing calculator returns 22.22 cu yd for surfacing to order. The supporting check is maintained depth: 9 in. Replace the prefilled measurements and supplier assumptions with the project values before ordering.

Planning limitation

This calculator is not a playground safety determination or certification. Follow current CPSC guidance, ASTM standards, manufacturer instructions, inspections, and local rules.

WHEN TO USE IT

Best use of this calculator

Use the result as a planning estimate, then verify field measurements and product-specific data before ordering or building.

INPUTS EXPLAINED

What each input means

Use-zone length: Enter the measured value and choose the matching unit (ft, in, yd, m, cm).
Use-zone width: Enter the measured value and choose the matching unit (ft, in, yd, m, cm).
Equipment fall height: Enter the measured value and choose the matching unit (ft, in, yd, m, cm).
Loose-fill material: Choose the option that matches the project: Wood chips, Engineered wood mulch, Sand, Pea gravel, Shredded rubber.
Installed loose-fill depth: Enter the measured value and choose the matching unit (in, ft, cm, mm).
Settlement / compression (non-rubber): Enter the project value in %.
Additional ordering waste: Enter the project value in %.
Price per cubic yard: Enter the project value in $.

COMMON MISTAKES

Checks that prevent bad estimates

Mixing units or entering a measurement in a different unit than the selected field unit.
Using a planning default when the exact manufacturer or supplier specification is available.
Rounding intermediate measurements too early instead of rounding the final purchase quantity.
Ignoring waste, compaction, cuts, laps, settlement, or full-package rounding where the project requires them.

SOURCES & REVIEW

How this estimate is supported

The implemented formula, assumptions, and worked example on this page are the calculator-specific reference. BuildYard's broader rules are documented in the Calculation Methodology and Sources & References.

For material density, coverage, yield, dimensions, package quantity, price, and other product-specific values, the current manufacturer or supplier specification should override a planning default.

COMMON QUESTIONS

Playground Surfacing Calculator FAQ

What does the Playground Surfacing Calculator calculate?

It converts the measurements for preliminary use-zone depth and purchase planning into the buying units normally used for loose-fill playground surfacing volume, with the relevant waste, package, weight, or cost outputs shown on the result card.

How accurate is this playground surfacing calculator?

The geometry is calculated from the values you enter. Final ordering accuracy still depends on field measurements, supplier density or coverage, product dimensions, compaction, cuts, and the selected allowance.

What should I verify for preliminary use-zone depth and purchase planning?

The entered maintained depth is converted to a larger initial installation depth using a separate settlement percentage; an over-limit fall height blocks the purchase estimate. Confirm the selected product, field conditions, and purchasing increments before placing the order.

Should I round the result up?

Yes for indivisible buying units such as bags, sheets, bundles, pallets, boxes, bars, and truck loads. The calculator rounds those purchase quantities up automatically.
