As a general guideline in the UK, a rider should weigh no more than 10% of the horse's bodyweight, but in the US, this limit is doubled to 20% of the horse's weight.
Deb Bennett, PhD, founder of the Equine Studies Institute and an expert in the biomechanics of horses, has advised that the “Total weight of rider plus tack must not exceed 250 lbs. There is no horse alive, of any breed, any build, anywhere, that can go more than a few minutes with more weight on its back than this.
How much weight can a horse carry? As a general rule, a horse can only comfortably carry up to 15–20% of its own body weight, though this may differ slightly from horse to horse. For instance, a horse that weights 500kg can comfortably carry a load of 100kg.
Q: Can a horse carry a 300 pound person? Some horses can carry a 300 pound rider, but your balance is also important. If you don't have a good balance then it'll be very difficult for even the largest horses to comfortably carry the weight.
According to THE U.S.CAVALRY MANUAL OF HORSE MANAGEMENT (1941) a horse should not carry more than 20 percent of its own weight.
You could be medically overweight, or even obese, by your BMI, but if your horse is big, strong and fit enough, with a saddle fitted well to you and him, and you're fit and balanced, it's possible you could ride him without an issue.
The maximum weight a horse can carry is 400 pounds based on the 20% rule. Most horses can safely carry 20% of their body weight. So a large draft horse weighing 2,000 pounds can theoretically safely carry a 400-pound person.
It depends on the size of the horse, which may range from 1,000 to 2,000 pounds. But let's say this man was riding an animal of appropriate size for him. For the man, that would feel like carrying roughly 30 pounds (about the weight of two bowling balls).
Based on these results, the study's authors recommend that horses not be loaded with greater than 20% of their body weight. A 545-kilogram (1200 pound) horse, then would be best off carrying no more than 109 kg (240 lbs) of tack and rider.
Horses should not be expected to carry more than 15% to 20% of their body weight. On a 450kg horse, that absolute maximum at 20% is 90kg. Anything above that is not fair to the horse and their well being is of utmost importance to us.
This means for a 500kg horse, the range for the maximum rider weight is large – 50kg in the UK (just less than 8st) and 100kg in the US (15st 10lb).
Ridden horses express pain through facial behaviors differently from horses at rest, one researcher says. Scientists have already described how to spot signs of pain, such as from colic or castration, in horses by their facial expressions.
Pilot studies have already demonstrated that a high rider-to-horse body weight ratio can induce temporary lameness. Chronic back pain and lameness, together with the horse negatively associating being ridden with pain, are foreseeable long-term outcomes.
Many horses willingly and happily opt to work with humans and express positive behaviors while being ridden. On the flip side, some horses run the other way when they look up from the round bale and see a halter in hand.
Most horses should be able to carry a rider and saddle that total 20-25% of their own body weight or less. This number varies based on the horse's fitness.
India's Prevention of Cruelty to Draught and Pack Animals Rules, 1965, says the maximum for mules is 200 kilograms (about 440 pounds) and for ponies the maximum is 70 kilograms (154 pounds).
In general, the rider should not be so tall as to look top-heavy on the horse, and the rider's feet should not hang much lower than the horse's belly when the stirrups are adjusted properly. Weight Rider and tack should not total more than about 20% of the horse's weight.
The researchers found that the increased rider weights did not significantly affect the heart rate, salivary cortisol, behaviour, and gait symmetry of horses. It should be noted that the maximum rider:horse weight ratios fell between 15 – 23 percent and the exercise intensity was relatively low.
In most cases, the bigger the horse, the stronger they will be. This also means that large horses have extra strength that you will need to be able to handle when riding them. If you simply can't muster the power, then you may not be able to exercise the right level of control when riding them.
If you want to ride in upper-level competitions, it's not uncommon for horses to get an intense training session 6 days a week. However, if you just want to keep your horse in a healthy physical condition, riding your horse three times a week for at least 20 minutes at a time can help maintain a good level of health.
If you weigh 250 lbs or more, you can still enjoy horseback riding as long as you ride the right horse. The safety of the horse and rider should always be the priority, so it is important to find the right horse breed that can heavy riders.
The horse breed that can carry the most weight is the shire horse. Average shire horses can weigh up to 2,425 pounds, and comfortably carry 20 percent of their body weight. This means the largest of shire horses can carry up to 485 pounds with ease.
Riders of ponies 12.3 – 13.2 hands may not weigh more than 150 pounds.
