Heavy As A Horse: How Much Horses Weigh With Charts & Calculator


When you share it really helps, Thank you! 🙂

Horses come in many different sizes. Discover the different weights of horses by breed, height, type and age. You may want to know a horse’s weight for different reasons such as figuring out carrying capacity, how much food a horse should eat, if a horse is underweight or overweight, dosing for medication or calculating weight for trailering.

Horses are large animals as you can tell. Maybe you may have heard the saying, “heavy as a horse” or equestrians referring to horses as a 1000 lb animal. That is partially true but not fully. As examples many horse products such as bagged grain and de-wormers use the 1000lb weight model because it is generally considered the average weight of a horse.

1000lbs or 454kg is the average weight for a light riding horse like a quarter horse. However the average weight for a pony like a welsh pony is a little more than half of that at around 600lbs or 272kg and a draft horse like a percheron is almost double the weight around 1700lbs or 771kg.

Horse weight can vary greatly depending on different factors. 

In this post I will provide you with easy to read reference charts with common horse weights based on height, breeds, types, and ages. I will also go over common factors that can play a part in a horses’ weight and why it’s important to know horses’ weight.

You can also find a calculator for figuring out your own horse’s weight toward the end of the post.

Horse Weight Factors

Forest, Horse, Fantasy, Nature, Light

These are a few of the factors that will affect how much a horse weighs.

Height & Width Can Affect Horses Weight

A taller horse typically weighs more than a short horse. Though this is not the only determining factor. You can expect your 16 hand thoroughbred to weigh more than your 10 hand shetland pony. 

A horse of the same height can have different widths. Take a 15.2h quarter horse and 15.2h thoroughbred. I have seen some quarter horses have similar bone density to a light thoroughbred. But say the quarter horse has the same bone density and height but has a wider body. That will add extra weight because there is still more bone and more horse.

Bone density Can Affect Horse’s Weight

Now looking at two horses with the same height and roughly the same width, they can have different bone density. The horse with heavier bone density will typically have thicker legs, bigger hooves, possibly a thicker neck and maybe bigger head. If both horses are at a healthy weight the horse with thicker bone density will typically weigh more.

Muscle & Fat Can Affect Horse’s Weight

As you have heard muscle weighs more than fat. However horses are commonly measured for weight with measuring tape or horse weight tape. So muscle weighing more than fat may not be taken into account when determining a horse’s weight, by the circumference of the horse’s girth.

Why Knowing Your Horses Weight Is Important

Horse, Animal, Mammal, Haflinger, Mane, Tail, Mare

In the beginning of this post I mentioned some reasons why you would want to know a horse’s weight and I am just going to touch on that a little bit here.

Knowing your horse’s weight helps you determine how much weight your horse can comfortably carry.

  • Carry capacity is the most amount of weight a horse is okay with carrying based on the horse’s own weight.
  • My blog post about ideal horse size goes into much more detail and has charts.
  • But basically a horse can carry up to 15-20% of their own weight.
  • If a horse carries too much weight the horse is at risk of soreness or injury.

Knowing your horse’s weight helps you determine how much to feed your horse.

  • There are other factors to determine the amount of grain along with weight such as age, metabolism, and activity level. Use this calculator to help determine grain type and amount with Purina Feeds.
  • Typically horses eat 2-3% of their weight.
  • The average horse eats 20-30lbs of hay every day and drinks up to 15 gallons of water.

Figuring out a baseline for your horse’s weight can help you monitor whether your horse is gaining or losing weight.

  • However, because horses can bloat, it is more accurate to take pictures.
  • Also, judge whether a horse is a healthy weight based on the horse’s body condition score.
  • In order for your horse to be a healthy weight, bones should not be showing or sticking out noticeably through the neck, withers, spine, ribs, croup, or tailhead.
  • Horse weight can fluctuate with the seasons.
  • In the winter horses tend to lose weight as they burn more calories and don’t have access to the additional calories of grass, so they need extra hay.
  • In the summer with the plentiful grass around, horses often gain weight, and sometimes horses gain too much. Some horses need muzzles to keep them from over-eating on the grass in the summer.

In order to medicate a horse properly and safely, you want to know your horse’s weight.

  • It is not as much of a problem to under-dose but if you overdose certain medications there can be major consequences.
  • So make sure you know your horse’s weight before measuring or ask your vet for the correct dosage amount.

If you are trailering horses you want to know the horse’s weights.

  • You need to make sure that the truck being driven can safely tow the total weight of the horses and trailer itself.
  • Different trailer models also have different carrying capacities.

Heaviest And Lightest Horse Weight

Shire Horse, Horse, Coupling, Reitstall, Animal World
Shire not Sampson

The heaviest horse lived in 1850’s and was a Shire gelding. His name was Sampson but was changed to Mammoth. He weighed a whopping 3,300lbs.

The lightest full grown horse was Thumbelina and lived until 2018. A dwarf miniature horse, she weighed a measly 57lbs.

The current heaviest horse is Big Jake a Belgian draft at 2600lbs.

Einstein is the lightest foal to be born, another dwarf miniature who was 3 pounds lighter than Thumbelina as a foal at 7lbs.

Horse Weight Ranges Based On Type

Shire, Horse, Otley, Show, Animal, Equine, Equestrian

Here is a general weight range in pounds and kilograms of the different horse types. Light horses I am counting as hotblooded and warmblood type horses. Miniature horses are typically smaller than ponies so I put them in a category of their own.

Draft Horses1500lbs-2200lbs680kg-998kg

Horse Weight Range Based On Age

Horse, Mare, Foal, Nature, Mammal, Equine, Animal

This chart is what to expect for a horse’s weight at different stages starting as a newborn. There are exceptions where horses can grow faster or slower but this is the general standards.

Age StageWeight 
NewbornShould weigh roughly 10% of mothers weight at birth
WeanlingFoal should be gaining 2-2/5lbs per day.
Yearling50% of full grown weight
2-Year-Old90% of full grown weight
4-Years OldThe last 10% of horses’ weight grows slower and is finished around 4 years old.

Horse Weight Calculator

First take the horse’s 2 measurements:

  1. The horse’s heart girth- This measurement goes all the way around the barrel where the girth would go. 
  2. The horse’s body length- This measurement is from the point of the horse’s shoulder to the point of buttock. Much easier measuring with 2 people.

Feel free to comment if there is anything else you would like to know about horse weight.

Till next time may horses put smiles on your faces!
