How to Estimate Body Weight With or Without a Weight Tape

Why Should You Know Your Horse’s Weight?

  • Medication and Supplement Dosing
  • Calculating Feed Intake Needs
  • Getting a Base Line Weight so You Can Better Notice Unplanned Weight Changes
    • gains or losses due to stress, diseases, feed quality, over/under feeding, over/under working
  • Tracking Progress for Growth, Intentional Weight Loss, or Intentional Weight Gain

Ways to Determine Your Horse’s Weight At Home

  • Weight Tape
    • Pros: Very easy! Just place a weight tape around the girth to withers (#1 in the picture below)
    • Cons: Not very accurate for horses that aren’t “square” (proportional length and girth sizes) or for horses with enlarged or thin abdomens
  • Using Girth Circumference and Length
    • Pros: More accurate than weight tape since it takes the horse’s shape into account
    • Cons: Math! But we’ve made this simpler for you using the included images and chart below
 

    1 – Wrap the weight tape around the girth and to the point of the withers* (snug but not tight). This is the girth circumference.

    2 – Measure from the point of the shoulder to the point of the croup*. This is the body length (you can use this to estimate blanket size too!).

    *Note: Tape will be slightly angled for both measurements for most horses.

    3 – Use the chart below to find the weight estimate for your horse’s measurements. Girth is along the left, and length is across the top.  Where the girth row intersects the length column, that is your horse's weight estimate (somewhere near the weights in yellow)

    4 Record your horse's weight to keep track of changes over time.

    Weight calculator

    Weights (in pounds) for adult horses calculated using the standard equation
    (girth * girth * length)/330

    To calculate weanlings weights, divide by 280 instead of 330. To calculate yearlings weights, divide by 301 instead of 330.

    If you need the weight in kilograms (kg), convert using the equation pounds/2.2 kg
