Does thick wool throw off the measurement?
Yes. Thick wool can increase girth measurement and make the estimate higher than the true live weight.
Sheep Weight Calculator
Estimate sheep live weight from body measurements.
Use heart girth and body length to estimate live weight when a scale is not available. This is a field estimate, not a replacement for actual weighing.
Calculate weight estimate
Select the unit system, enter measurements and calculate an estimated live weight.
Estimated Live Weight-
Alternative Unit-
Use estimated weight carefully.
Measurements help when there is no scale, but wool thickness, body condition and breed type can affect the estimate.
Should I replace scale weights with this?
No. Use it for rough field planning and record actual scale weights when possible.
Where should the result go?
Use HerdDeck animal cards to keep real weights and notes connected to the animal history.
Method note
This calculator estimates live weight from body measurements. It is a field estimate, not a scale replacement. Breed, body condition, fleece, pregnancy, measurement technique, and local formulas can change the result.
