Bale Weight Calculator
Estimate round hay bale weight using bale diameter, width, and forage density.
Inputs
How It Works
Bale Weight (lb) = π × (Diameter ÷ 2)² × Width × Density
The bale is treated as a cylinder. We calculate cubic volume and multiply by forage density to estimate total pounds.

FAQ
How much does a 5x5 round bale weigh?
Most 5x5 bales weigh between 800–1,200 pounds depending on moisture and density.
What density value should I use?
Typical dry hay ranges from 8–14 lb per cubic foot. Tighter baling and higher moisture increase density.
Does moisture affect bale weight?
Yes. Higher moisture significantly increases bale weight because water adds mass.
Understanding Bale Weight
Knowing bale weight is essential for forage inventory, transportation planning, and livestock feeding management. Bale weight depends on three primary factors: diameter, width, and forage density.
Round bales are cylindrical in shape, meaning volume increases rapidly as diameter increases. A small change in bale size can significantly impact total weight.
Density varies based on moisture content, baler settings, forage type, and storage conditions. Accurate bale weight estimates help producers manage feed supplies efficiently and prevent under- or over-estimating forage availability.
