Snow Load Weight Calculator


Calculating snow load weight is crucial for designing structures in regions prone to heavy snowfall. A snow load weight calculator simplifies this task by providing accurate estimates based on established formulas. In this article, we'll discuss how to use such a calculator effectively, along with the underlying formula and an example solve.

How to Use

Using the snow load weight calculator is straightforward. Input the required parameters, such as snow density, roof pitch, and dimensions, then click the "Calculate" button to obtain the estimated snow load weight.


The formula for calculating snow load weight is:

Snow Load Weight=Density × Gravity × Depth × Area × Load Factor


  • Density is the density of the snow in kg/m³.
  • Gravity is the acceleration due to gravity (9.81 m/s²).
  • Depth is the depth of the snow in meters.
  • Area is the surface area in square meters.
  • Load Factor is a coefficient based on the roof pitch and shape.

Example Solve

Let's say we have a roof with the following parameters:

  • Snow density: 200 kg/m³
  • Depth of snow: 0.5 meters
  • Surface area: 100 square meters
  • Roof pitch: 30 degrees

Using the formula:

Snow Load Weight=200×9.81×0.5×100×Load Factor

After calculating, let's assume we find the snow load weight to be 9810 N.


Q: What units should I use for input parameters?
A: It's recommended to use consistent units such as kilograms for mass, meters for length, and square meters for area.

Q: How accurate are the results from the calculator?
A: The calculator provides estimates based on the provided parameters. However, real-world conditions may vary, so it's advisable to consult with a structural engineer for precise calculations.

Q: Can the calculator handle different roof shapes?
A: Yes, the calculator considers the roof pitch and shape through the load factor parameter, allowing for accurate calculations for various roof types.


A snow load weight calculator is a valuable tool for architects, engineers, and builders working in snow-prone regions. By understanding how to use it effectively and the underlying formula, professionals can ensure the structural integrity of buildings under snowy conditions.
