How Much Does Snow Weigh

One winter storm can deposit several inches of snow on your roof and it’s important to know how much snow your roof can safely hold. The weight of fresh, dry snow is about one pound per cubic foot, but the weight of wet snow is only about half that. A ten-inch layer of fresh, dry snow would weigh approximately 5 pounds per square foot while the same depth of wet snow would only weigh 2.5 pounds per square foot.

How much does snow weigh? Here's the math

A single cubic foot of dry snow typically weighs between 7 and 16 pounds, depending on the density. The weight of wet snow is generally about 10% to 20% higher than that of dry snow.

How Much Does 8 Inches of Snow Weigh?

The average snowfall in the United States is about 10 inches. One inch of fresh snow weighs approximately one pound per cubic foot, so ten inches of new snow would weigh around 10 pounds per cubic foot, or 80-100 pounds for an average car. In most cases, ice and freezing rain are more dangerous than snow because they are less visible and can cause unexpected slippery conditions.

How Heavy is 12 Inches of Snow?

Assuming you are referring to freshly fallen snow, 12 inches of snow would be approximately 2 pounds per square foot. So, if you had a square area that was 12×12 inches, that would be 144 square inches and would weigh around 288 pounds.

How Much Does Snow Weigh on a Roof?

When it comes to the weight of snow on a roof, it really depends on the type of snow. For example, dry snow is much lighter than wet snow. A cubic foot of dry snow can weigh as little as 10 pounds, while a cubic foot of wet snow can weigh up to 60 pounds.

The depth of the snow also plays a role in how much it weighs. For instance, a foot of fresh powdery snow may only weigh about 20 pounds per square foot, but if that same foot of snow is packed down and icy, it could easily weigh double or even triple that amount. And finally, the temperature also has an effect on how much weight your roof can handle.

If it’s very cold outside (-15 degrees Fahrenheit or lower), the air is actually capable of supporting more weight than if it were warmer (around 32 degrees Fahrenheit). This is because cold air is denser than warm air, so it can hold more Snow! So how much does all this mean for your roof?

It really varies depending on all these factors – but generally speaking, most roofs are designed to support at least 20-30 pounds per square foot without any problems. So unless you’re dealing with an unusually large amount of heavy wet snow, or your roof is already in poor condition, you shouldn’t have anything to worry about!

How Heavy is 4 Feet Snow?

Assuming you are referring to freshly fallen snow, the answer may vary depending on the type of snow. For example, “fluffy” snow may be lighter than wet and compacted snow. However, according to The Calculator Site, 4 feet of fresh snow generally weighs between 60 and 80 pounds.


One cubic foot of snow can weigh between four and five pounds. It all depends on the density of the snow. The average person produces about seven pounds of waste every day.
