Raised Floors/Pedestals Calculator

Before You Start

Get a fast, reliable estimate by gathering the items below.
Clear inputs mean better results and fewer revisions.

What you’ll need (required):

A plan or sketch with the install area outlined and perimeter dimensions.
If not to scale, include one known dimension for calibration.
Elevations at lowest points/drains/perimeter and whether they include flooring thickness.
Slope percentage and direction.
Flooring size(s) and thickness (note any size mix).

Optional but helpful:

Obstructions/keep‑outs (columns, parapets, hatches, curbs).
Zones for areas with different slopes/heights.
Overage preference (add 3–5%).
Units: Metric or Imperial.

In the tool you will:

Draw the perimeter and set the heights;
When needed, add drainage points;
Choose the components, accessories and options;
Output your plan and full list of components.

Assumptions & best‑practice notes

The calculator places supports based on the entered format and traced area; results vary with slopes, drains, and obstructions.
Extreme slopes, compound falls, or uneven substrates can alter quantities—split into zones for best accuracy.
Very thin or unusually large/heavy units may require different support strategies. Follow the product’s Technical Data Sheet and local codes.
