How to Calculate Cattle Weight

Unless you are a commercial livestock farmer, you probably do not own a livestock scale. Figuring out how to weigh a cow, bull or calf is easy if you can measure the animal body length and girth. Use this guide to determine the weight of your dairy cow or beef cattle:

  1. Measure the circumference of the animal, as shown in "distance C" in the illustration. Make sure to measure girth in relation to the location of the animal's heart.
  2. Measure the length of the animal's body, as shown in distance A-B in the illustration.
  3. Using the measurements from steps 1 and 2, calculate body weight using the formula HEART GIRTH x HEART GIRTH x BODY LENGTH / 300 = ANIMAL WEIGHT IN POUNDS. For example, if a beef cow has a heart girth equal to 70 inches and a body length equal to 78 inches, the calculation would be (70 x 70 x 78) / 300 = 1,274 lbs.
