Horses come in all shapes and sizes, from petite miniatures to massive draft breeds. So how much does a horse weigh on average? The answer depends largely on the breed. While miniature horses tip the scales at just a couple hundred pounds, heavy draft horses can weigh well over a ton!
A Quick Overview on Average Horse Weight
The average full-grown horse weighs between 800 and 1,200 pounds. However, weight ranges dramatically by breed. Miniature horses weigh between 150-250 pounds, while draft horses weigh 1,800-2,200 pounds or more. Other factors like the horse’s height, bone structure, and muscling also impact overall heft.
While genetics plays a big role in determining size, the horse’s diet and exercise regimen also affect weight. Overfeeding concentrates like grain while limiting roughage can cause obesity. On the other hand, an active horse fed a balanced diet will likely maintain a moderate, healthy weight.
Now, let’s explore how much specific breeds typically weigh.
Thoroughbred Weight

Thoroughbreds are known for their lean frames and athleticism. These hot-blooded horses were originally bred for racing, so their builds favor speed over bulk. The average Thoroughbred stands between 15 and 17 hands high and weighs about 1,000 pounds. However, their weight fluctuates significantly based on age, sex, and fitness level.
- Young racehorse prospects generally range from 800 to 1,000 pounds.
- Mature stud horses weigh 1,100-1,300 pounds on average.
- Adult mares weigh around 1,000 pounds or slightly less.
- Thoroughbreds gain weight after retiring from racing if not kept fit.
Since lighter thoroughbreds have an edge on the racetrack, most trainers carefully regulate these horses’ diets to avoid excess fat. But without intensive exercise, these breeds are prone to obesity in retirement.
Quarter Horse Weight

Originally bred to race short distances and work cattle, quarter horses are stocky and muscular. Today they’re one of America’s most popular breeds, used for a variety of equestrian activities from reining to ranch work. Quarter horses stand 14 to 16 hands high and weigh an average of 1,000 to 1,300 pounds.
- Quarter horse stallions often reach 1,400 pounds or more.
- The typical mare weighs around 1,100 pounds.
- Young quarter horses range from 800 to 1,000 pounds until maturity around age 5.
- Overfeeding and inactivity quickly lead to weight gain in quarters.
Since quarter horses are middle-weight breeds, they can suit a wide range of riders and disciplines with proper conditioning. Avoid obesity by feeding grass or alfalfa hay, limited grain, and plenty of turnout exercise.
Miniature Horse Weight

The smallest equine breed, miniatures measure less than 34 inches tall at the withers. Miniature horses weigh between 150 and 250 pounds on average. Factors like genetics, gender, and diet impact their overall size and weight.
- Well-bred mini stallions often weigh 200-250 pounds.
- Petite mini mares may only weigh 150-175 pounds.
- Overfeeding leads to rapid weight gain in minis. Limit treats and rich feeds.
- Provide plenty of hay and pasture access to prevent minis from becoming overweight.
With their tiny statures and weights, minis aren’t suitable for riding. But these pint-sized equines make delightful pets and therapy animals when properly trained. Just be careful not to overfeed them!
Clydesdale Horse Weight

Clydesdales are gentle giants, with their flashy feathers and tall stature. These draft horses originated in Scotland, where farmers bred them to haul heavy loads and plow fields. Full-grown clydesdales stand 16 to 18 hands high and weigh between 1,800 and 2,200 pounds.
- Breeders aim for stallions to reach 2,000 pounds or more.
- The average clydesdale mare weighs around 1,800 pounds.
- Young horses weigh 1,500-1,700 pounds before finishing growing around age 5.
- Obesity is uncommon since these horses are working breeds.
With their immense size and strength, clydesdales make impressive hitch horses for pulling wagons and sleighs. Their weight must be carefully managed through diet and exercise to prevent lameness issues.
Draft Horse Weight

Draft or draught horses are heavyweight breeds including Clydesdales, Percherons, Belgians, Shires, and more. While specifics vary between breeds, most weigh between 1,800 and 2,200 pounds. However, individual size depends on bloodlines, gender, age, and use.
- Massive draft stallions can reach 2,400 pounds or more.
- The typical draft mare weighs around 2,000 pounds.
- Young draft crosses often weigh 1,500 pounds before full maturity.
- Retired plow horses are prone to obesity without ample exercise.
Originally bred to perform farm work, today’s draft horses primarily compete in pulling competitions or provide horsepower on sustainable farms. Their sheer size makes them difficult mounts for riding. Always provide free-choice hay and monitor grain intake to prevent excess weight.
Other Horse Breed Weights

While we’ve covered some of the most popular breeds, dozens more exist worldwide. Here’s a quick look at the average weight of a few other types:
- Arabians range from 800 to 1,000 pounds.
- Morgans often weigh around 1,000 pounds.
- Paints and pintos average 1,000 to 1,200 pounds.
- Appaloosas are usually over 1,000 pounds.
- Warmbloods like Dutch Warmbloods weigh 1,200 pounds or more.
- Tennessee walking horses range from 1,000 to 1,200 pounds.
Regardless of breed, the healthiest weight for any horse is one that allows it to easily perform its job. Obesity stresses joints and invites laminitis and other issues in horses. Work closely with your veterinarian or equine nutritionist to tailor your horse’s diet and exercise to maintain optimal heft.
5 Factors That Influence Horse Weight
While breed genetics account for much of the differences in horse weights, other factors also contribute. Here are 5 things that affect how much a horse weighs:
1. Age
Horses rapidly gain weight as they mature from birth to age 5. Their growth plates don’t fully close until well into physical maturity around age 6. Maximum weight is reached between 8 to 10 years old for most breeds.
2. Gender
Due to hormones and muscular differences, stallions typically weigh 10-15% more than mares. Castrated geldings are intermediate in weight compared to intact males and females.
3. Diet
Overfeeding energy-dense grain while limiting roughage puts weight on horses. On the other hand, an active horse fed only hay requires extra calories to avoid dropping pounds.
4. Workload
Horses in heavy training shed excess weight from the demands of exercise. But inactive horses require rationed feeding to prevent obesity.
5. Health
Illness, dental issues, chronic pain, and parasites can all contribute to decreased appetite and weight loss in horses. Veterinary care helps ensure horses stay healthy.
Maintaining your horse at a moderate, healthy weight takes balancing their innate metabolism with diet and exercise. But the work pays off by reducing obesity risks that threaten their health and soundness.
Frequently Asked Questions About Horse Weight
New and experienced horse owners alike often have questions about equine weight. Here are answers to some of the most common queries:
How often should you weigh your horse?
You should weigh your horse every 2-4 weeks to monitor any weight changes. More frequent weighing isn’t necessarily helpful since horses’ weights fluctuate daily.
What is the easiest way to weigh a horse?
Using an equine weight tape is the simplest method. These tapes measure the horse’s girth circumference and length to estimate weight.
Is it OK for horses to be overweight?
No. Excess weight stresses the joints, circulation, and hooves. Overweight horses are prone to laminitis, insulin resistance, bone spavin, and reproductive issues.
What are the risks of a horse being underweight?
Thin horses lack crucial fat and muscle reserves to stay energized and healthy. Underweight also signals potential health issues or malnutrition that require veterinary attention.
Should I feed my horse grain if they are underweight?
Introduce calorie-dense grains like oats slowly if your horse needs weight gain. Divide the ration into several small meals and monitor intake to prevent colic and CHO overload.
How much hay and pasture time should horses get?
Horses’ main diet should be roughage from hay and/or pasture grazing. Provide 1.5-2% of the horse’s body weight as hay per day if confined without turnout.
What is the best way to help an overweight horse lose weight?
Limit or eliminate grain, provide hay in a slow feeder net, employ a grazing muzzle in pasture, and increase exercise for an overweight horse.
Monitoring your horse’s weight is important for their health and performance. While genetics determine their general size, proper nutrition and management play a huge role in keeping your horse at a fit, functional heft. Work with your veterinarian and equine nutritionist if you have concerns about your horse’s weight. With some tweaks to their diet and exercise, you can get your horse back into top shape.
The Takeaway: Discover Your Horse’s Ideal Weight
While breed averages provide a starting point, the ideal weight for any horse depends on their conformation, workload, and overall health. Thin horses lack the reserves to stay strong and active. But those carrying excessive pounds place dangerous stress on their limbs and metabolism.
Weigh your horse at least monthly to catch any creeping weight issues early. Address problems through nutrition changes or veterinary advice before they create lasting damage. And as the scales start to shift, adjust your horse’s diet and exercise again to maintain their optimum healthy heft.
Though it takes some diligence, keeping your horse trim or adding some needed pounds pays dividends in their happiness, performance, and longevity. By regularly weighing your equine and fine-tuning their feeding and activity, you’ll discover and provide the perfect weight to keep them feeling their absolute best.
