How to use the Snow Load Calculator

The Snow Load Calculator works out your snow load in an instant. Enter snow depth and snow density and the result updates as you type — it is free, needs no sign-up, and runs entirely in your browser so your figures stay private.

  1. Enter the snow depth.
  2. Enter the snow density.
  3. Read off your snow load — the calculator updates automatically, with no button to press.

Formula

The Snow Load Calculator uses the formula:

Snow load = Snow depth ÷ 100 × Snow density

Worked example

For example, with snow depth of 30 cm and snow density of 300 kg/m³, the snow load is 90.0.

Inputs used
Snow depth 30 cm
Snow density 300 kg/m³
Results
Snow load 90.0

Results are estimates for educational use, not professional advice.

Key terms explained

Density
Mass per unit volume, calculated as mass ÷ volume.

Frequently asked questions

Multiply snow depth in metres by its density. 30 cm of snow at 300 kg/m³ gives a load of about 90 kg/m².

Fresh light snow is around 50–100 kg/m³, settled snow 200–400, and wet or packed snow can exceed 500 kg/m³.

Heavy snow can overload roofs and cause collapse. Knowing the load helps judge whether clearing is needed.

No. It is an estimate. Building design uses code-specified snow loads with safety factors; consult an engineer for structures.
