Horse breeds · from TrotleyHolsteiner weight and height: a warmblood size guide and what carrier testing means
Holsteiners mature at 16 to 17 hands, and while no source gives a breed weight, warmbloods as a group averaged 1,300 pounds in a University of Minnesota study.
Short answer
Holsteiners stand 16 to 17 hands, and warmbloods as a group average 1,300 pounds.
The University of Kentucky lists 16 to 17 hands (64 to 68 inches), and the International Museum of the Horse says the breed matures between 16 and 17 hands. No source opened for this page gives a Holsteiner weight, so the best available estimate is the University of Minnesota’s average of 1,300 pounds (590 kg) for 89 adult warmbloods.
University of Kentucky, International Museum of the Horse and University of Minnesota Extension (the weight is the warmblood group figure)
| Source | Height | Weight |
|---|---|---|
| University of Kentucky | 16 to 17 hands | Not given |
| International Museum of the Horse (archived 2020) | Matures at 16 to 17 hands | Not given |
| University of Minnesota, 89 adult warmbloods (all breeds) | Average 66 inches (16.2 hands) | Average 1,300 lb |
The Minnesota figures describe warmbloods as a group, mostly seen at a hunter and jumper show, and not Holsteiners alone. Oklahoma State University has no Holsteiner page.
Two height sources agree, and one weight stands in
Kentucky and the museum give the same one hand span, 16 to 17 hands, which is 64 to 68 inches at the withers. The weight estimate borrows the Minnesota warmblood average, and a Holsteiner of finer or heavier build can sit well away from it, so a tape reading from your own horse is worth more than any table.
Daily hay for a 1,300 pound Holsteiner
The arithmetic uses 1,300 pounds, the Minnesota warmblood average. Merck says warmblood breeds tend toward the lower end of its intake range.
Merck gives 2 to 2.5% of body weight in feed dry matter as the usual starting range for a healthy adult, with at least half from forage, 1.5 to 2% as the goal for a horse that needs to lose weight when laminitis is not a worry, and 1.25% as the floor. The figures below are our arithmetic from 1,300 lb, counting hay as 90% dry matter, which is our assumption.
- 1.5% of body weight: 20 lb (9 kg) of dry matter, about 22 lb (10 kg) of hay
- 2% of body weight: 26 lb (12 kg) of dry matter, about 29 lb (13 kg) of hay
- 2.5% of body weight: 33 lb (15 kg) of dry matter, about 36 lb (16 kg) of hay
A weight tape example for a Holsteiner
The horse weight calculator runs the adult equation from the Merck Veterinary Manual: measure heart girth and body length in inches, square the girth, multiply by the length and divide by 330 to get pounds. A heart girth of 77 inches and a body length of 68 inches gives 77 x 77 = 5,929, times 68 = 403,172, divided by 330 = about 1,222 lb (554 kg). Those measurements are our illustration of the formula, not a real horse.
Merck says the equation and tapes tend to underestimate weight, and the Minnesota study found draft horse and warmblood owners about 115 pounds, or 7%, off on average. Use a scale when you can, and measure the same way each time.
What a carrier result means
UC Davis says fragile foal syndrome type 1 is recessive, with an estimated carrier frequency of 9 to 11% in warmbloods, and recommends the DNA test for all warmblood and sport horse populations. Carriers have no known health problems.
The numbers show why testing is a breeding tool: two carriers have a 25% chance of an affected foal, while a carrier bred to a horse without the mutation cannot produce one, and half of their foals are carriers. Ask your vet or registry which results you need before a mating.
Feeding a sport horse
Merck says feeding more than half the ration dry matter as high starch or sugar concentrates raises the risk of laminitis, colic and gastric ulcers. The University of Georgia warns that large amounts of grain can lead to colic and ulcers, and suggests replacing some carbohydrate with fat for horses in hard work. Merck adds that many horses on good forage need little or no concentrate, with hard-working horses among the exceptions, so ask your vet before changing feed.
Body condition
Merck advises a score of 4 to 6 on the 9 point Henneke scale. The Minnesota warmbloods averaged 5.2 and only 2% scored 7 or more. Score your horse by feel monthly and log the score with each weight.
Frequently asked questions
How much does a Holsteiner weigh?
No source opened for this page gives a Holsteiner weight. The University of Minnesota’s adult warmbloods averaged 1,300 pounds (590 kg), which is the best available estimate.
How tall is a Holsteiner?
The University of Kentucky lists 16 to 17 hands, and the International Museum of the Horse says the breed matures between 16 and 17 hands, which is 64 to 68 inches.
How much does a Holsteiner eat a day?
For a 1,300 pound horse, 2% of body weight is 26 pounds of dry matter, about 29 pounds of hay, and 1.5% is about 22 pounds. Merck says warmbloods tend toward the lower end. These figures are our arithmetic.
Can a Holsteiner carry a 200 pound rider?
The University of Minnesota reports that an average adult light riding horse can comfortably carry about 20% of its ideal bodyweight, rider and tack included. For 1,300 pounds that is about 260 pounds, so a 200 pound rider with 25 pounds of tack is inside it. Fitness and conformation change the answer.
