Enter the Gross Vehicle Weight into the calculator to determine the winch size.

Winch Size Formula

The following formula is used to calculate the winch size.

WS = GVW * 1.5


  • WS is the winch size (lbs)
  • GVW is the Gross Vehicle Weight (lbs)

To calculate the winch size, multiply the Gross Vehicle Weight by 1.5. This will give you the minimum winch size needed for your vehicle. It is recommended to choose a winch size that is rated for at least 1.5 times the weight of your vehicle to ensure safety and efficiency.

What is a Winch Size?

A winch size refers to the pulling capacity of a winch, which is a mechanical device used to pull in, let out, or adjust the tension of a rope or wire rope. The size is typically measured in pounds and indicates the maximum amount of weight the winch can handle. It’s crucial to choose the right winch size for the task at hand to ensure safety and efficiency. For instance, if you’re using a winch for a vehicle, the general rule is that the first layer of rope around the drum is the max load the winch can handle.
