I found this excellent post on horses on Dan Koboldt’s blog. It is part of his weeklyΒ Science in Sci-fi, Fact in FantasyΒ blog series, where he tackles one of the scientific or technological concepts pervasive in sci-fi (space travel, genetic engineering, artificial intelligence, etc.) with input from an expert.

His post on horses was actually a guest post, written byΒ Rachel Annelise Chaney; a woman who spent her childhood inhaling every scrap of horse information she could find and riding every equine she could climb on. Since adopting an ex-racehorse, sheβs ridden, trained or cared for everything from Thoroughbreds to Quarter Horses, Drafts to Arabians, Warmblood jumpers to Paint barrel racers. A reader and writer of SFF, Rachel currently languishes in the Eternal Pit of Revision. You shouldΒ follow her on Twitter. Send coffee. Ignore frustrated screams.
As, for some reason, I was unable to reblog, I opted for including here a summary of Rachel’s post. You can read the full post on Dan’s blog.
Casting Horses in Fictional Worlds
Matching your mount to your world and/or character can be a tricky business and Hollywood will steer you wrong every time. Using the wrong horse mayΒ seemΒ like a little thing, but it will rip horse-knowledgeable readers right out of your story. Three key issues to consider when writing your fantasy-land horses are:
- The horseβs use of purpose
- The climate the horse lives in
- Your characterβs horse experience
Let’s take them one-by-one below.
1. A Horseβs Use Of Purpose
Contrary to popular belief, horses are not all-purpose.Β Like dogs, humans developed horse breeds over centuries of selective mating. Each breed was created for a specific purpose. So, the first thing you should do is pinpoint your horseβs purpose. Are they a knightβs mount? An over-rough-terrain horse to take your character on a trek? A noblemanβs hunter or a cavalry steed?
Each purpose takes a different kind of horse.
A Knightβs Horse: The Irish Draught
So youβre writing a Medieval Fantasy and have armored warriors that need to charge into battle. You might be thinking they need a big horse, tough and muscled. Something like the Budweiser Clydesdales, perhaps?
Sorry, but no. Contrary to popular belief, most armored knights did not use giant, heavy draft horses. Based on recovered equine armor and illustrations, knightsβ mounts (known asΒ chargersΒ orΒ destriers) tended to be short-to-average height at 14-16hh, tall and stocky.
Reason: If unhorsed, an armored warrior needed to be able to leap back on his mount. Those 18hh drafts? Not happening! A 15hh horse? Absolutely!
The smaller, stocky build is also better for sharp turns, kicks, rears, and charges in the heat of battle. Most draft horses are known as Gentle Giants. The fire needed for battle? Not their thing.
The closest modern equivalent to the medieval charger: the Irish Draught (pictured).
Horses for Long Treks: Mongol or Egyptian Arabian
The most common mistake in books, movies, and TV shows is the use of fine-boned horses on long treks, frequently Thoroughbreds. When most people think of horses, the thoroughbred tends to be the default view of how they look, move and act. Thoroughbreds are great. They have lots of heart, so they would go on that long trek over the mountains and through the woods if asked. But they would drop weight, probably get injured or dehydrated, and definitely suffer from fatigue.
If your character is going on a long trip, give them a sturdy mount, like the hardy Mongol horse. Or Napoleonβs small but intrepid Marengo, an Egyptian Arabian, who carried the French dictator through the Alps. The smaller horses may not be able to whisk your character away from danger or magnificently rear, but theyβd laugh in the face of exhaustion or hazardous conditions.
Hunting/Cavalry Horses: Thoroughbreds and Warmbloods
Both hunting horses and post-Medieval cavalry horses shared similar job descriptions and necessary skills. For hunting, a horse needed to be energetic enough to leap obstacles, fast enough to keep up with prey, and cool-headed enough to listen to its rider.
After the rise of gunpowder weapons and the fall of armor, the physical conformation of cavalry horses shifted. Instead of short, stockyΒ chargers, cavalry mounts got taller and leaner. They had to be fiery enough to charge into the fray, nimble enough to get their riders out of lethal situations, yet calm enough to obey commands immediately.
The closest modern equivalents to these horses are Thoroughbreds and Warmbloods β the same breeds that compete in the equestrian sports that evolved from cavalry training.
If youβre writing a noblemanβs hunter (from any era) or a for-pleasure mount or a Flintlock Fantasy, stick to thoroughbreds and warmbloods. Theyβre tall (15.2-18hh), muscular, fast and agile.
However, be sure to take into account the owner’s financial situation. If you find yourself describing your characterβs horse as big and black with a flowing mane and tail and feathered feet, stop! Warmbloods likeΒ Friesians areΒ extremelyΒ costly. Always have been. Theyβre amazing animals, but they are NOT cart, commoner, or insane asylum carriage horses. Looking at you, Beauty and the BeastΒ (2017).
The Bottom Line on Horse Use
- Does your horse have a specific use? Keep descriptions in line with the breeds intended for that.
- DoΒ notΒ give your commoner a Friesian. Donβt give anyone a Friesian unless theyβre A) rich B) need a Warmblood.
2. Matching Horse to Climate
Misconception: Horses are hardy and can weather harsh climates.
Reality: Horses are both surprisingly tough and exceptionally fragile. If your world features harsh or unusual climates, match your horses to that world.
Horses for Hot and Dry Climates
Are your characters moving through a desert, rocky wasteland, or otherwise hot and arid world? Donβt pull aΒ Game of ThronesΒ and put heavy horses in there. You wouldnβt stick a Siberian husky in the desert, would you?
Big, muscly horses need lots, lots, LOTS of water, food and forage to maintain that size. In reality, those Friesians the Dothraki ride across wastelands would likely die of dehydration and heat exhaustion.
If youβre writing a desert world, go for a breed that snorts in the face of extreme heat and lack of vegetation β like Arabians, Akhal-Tekes, or Marwaris. Like these breeds, your mount should be lean, compact, and light on their feet. On the shorter side (14-16hh), the desert breeds are masters of endurance. Need to go a couple thousand miles? Theyβve got you covered!
Horses for Cold and Snowy Climates
These smaller, leaner equines can take you for longer distances, with less food, than a heavy mount.
On the flip side, donβt put that Arabian in a wintry climate! You wouldnβt put a Husky in the Sahara, so donβt put a greyhound on the Alaskan sled team.
Most horses can weather cold temperatures with blanketing and care by their owners. But if your setting features below zero temps, snowstorms, or persistent wintry conditions, you may need to consider going with a horse breed designed to live in freezing climates.
Cold weather horses tend to be heavier than the average riding horse and grow out a thick, fuzzy coat in the winter. While a big draft horse fits the bill, smaller breeds like the Icelandic Horse or the Fjord are great examples of a horse designed for cold winters and mountainous terrain.
If your setting is mountainous, icy or subject to freezing temps, the best match for your world is a horse with strong hooves, thick muscles, and super fuzzy winter coat. How tall or short they should be depends on their purpose.Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β Β
The Bottom Line on Climate
If you have an unusual setting or climate, pick a breed that matches. If your setting doesnβt have extreme weather or unique terrain conditions, refer to the prior section on matching your mount to its purpose. Nearly all breeds can survive just fine anywhere that doesnβt have extreme hot or cold.
3. Matching Horse to Character
Misconception: Horses are living bicycles. If you learned how to ride, you can ride any horse.
Reality: Every horse has a will, emotions, personalities, and quirks. They think, feel, act and react.
Matching your specific character to a complementary horse is a case-by-case issue, and not necessarily important unless horses are a vital part of your narrative. There are, however, a couple of big issues you should avoid.
About Stallions
If your character is not an experienced rider, doΒ NOTΒ put them on a stallion! Donβt put anyone on a stallion without a solid reason.
As much as Hollywood likes Friesians, books and movies like stallions even more. Most stallions are temperamental, aggressive, and dangerous. Calm, attentive stallions do exist, but theyβre the exception to the rule. When in doubt, go with a gelding or mare.
Horse Temperament
On the same note, donβt give your character a cool, spirited horse if theyβre a nervous or excitable type. Horses are incredibly perceptive, and however a rider is feeling translates through their body and language and down the reins to the horse.
Is your character a confident, skilled rider? Sure, throw them on that fiery steed! Otherwise, I wouldnβt recommend it.

Thanks for sharing informative post about horses.
Thank you so much, Linnea π
Excellent post, Nicholas, and I’m going to check out the original. I did tons of research for my “horses” since they appear in most of my books. Details are great because they add authenticity to a speculative world, but unless a writer is willing to learn about the variations in these fascinating animals, it’s probably better to go generic.
The post made me realize how little research I had done when I was writing Pearseus. Thankfully, I’d gone generic, so no major blunders there π
I think that applies to most things – armor, weapons, fighting techniques, mechanical systems… we can throw some details in there if we know them, but generic works, too. Readers are great at filling in the gaps. Plus, too many details about everything would bog down a story. π
I have always love horses, and horse stories – Black Beauty being one of my earliest reads as a child. Thanks for this post!
Oh, the memories your comment brought back π
I have never mentioned a horse in a story, so these are great tips, if I ever do.
Best wishes, Pete.
Aren’t you tempted now? π
I know so little about horses,,, π
I know pretty little about spaceships, but that’s never stopped me π
True!
