Did you ever measure your horse? You need to know that it is very important to do so because while riding a horse, your weight needs to be compatible with your horse (a horse should be at least 5 times heavier than the rider). If you didn’t weigh your horse yet, below you will find an online estimator of your horses weight.
The most accurate way to determine a horse’s weight is by weighing him on a scale. However, you can estimate a horse’s weight (to calculate proper amounts of feed, dewormer, etc.) by using body measurements. Weight tapes use a horse’s heart girth measurement alone, but using body length plus heart girth tends to be more accurate.
Please Note: The Adult Horse Weight Calculator is intended for use only as a weight estimation tool. It does not consider physical differences between individual horses.
If an accurate weight for your horse is necessary for any purpose, scales must be used. However, do not count only on this estimator, instead consult with your vet for a proper way how to measure your horse. https://thehorse.com/tools/adult-horse-weight-calculator/
