Quite simply, how do the people(?) and things in the MLP universe compare to real-world equivalents? Are the ponies the size of people, or RL ponies? Or smaller/bigger? How about things like trees or houses?

    MLP is DEFINITELY on topic here as it is fantasy. If talking and flying ponies isn't a fantasy concept I want to live where you're living, or smoke what you're smoking! – Edlothiad Jul 30 '17 at 7:09

In Hearth's Warming Eve, Twilight said, "I spy an 8 foot candy cane." Scootaloo was standing next to it. Comparing Scootaloo and the candy cane together, we can estimate that she is about 3 feet tall. Adult ponies are slightly taller, I estimate 4 feet. Because the ponies are in the same proportion to houses, trees, etc. in their world as we are in ours, it can be assumed that these things were shrunk down for proportion.

    @Keen Of course they aren't, pony feet are hooves :) – Tacroy May 30 '12 at 21:05

    I completely agree with the 8-foot-candy-cane scale. If the ponies are, in fact, ponies, this scale makes sense, as any equine under around 5 feet is considered a pony. Interestingly, Luna and Celestia would then qualify as horses, being around six or seven feet to the head. – Unhelpful answer brony Nov 6 '12 at 3:59

    Alicorns don't count! Also horses aren't even measured with feet, they're measured by hands! – Rob Nov 25 '13 at 14:12

    @Rob: A pony is any breed of horse which, when fully grown, is between 9.5 and 14.3hh (hands high). 4ft is 12hh. While not an answer to the OP's question, my personal take puts the MLP characters around 10hh (~3.33ft), which would make them little ponies ;) (Also: MLP ponies have a concept of "horses," distinct from "ponies." Flim and Flam sing "any horse can make a claim and any pony can do the same," and in the current season, the Crusaders sing about having "hearts as strong as horses.") – Brian S Jan 14 '14 at 16:12

As of Pinkie Pride, we have another scale to go on; Cheese Sandwich stands against a height chart.

Cheese Sandwich Height Chart

There is one major, glaring flaw with the calculations above: They measure from the top of a pony's head to the ground. This is understandable, as it's what you do when measuring a human's height, and we're humans (most of us...); unfortunately, that technique doesn't work for quadrupeds, who can move their head up and down a considerable distance, and do so frequently (especially the two characters measured in this image!)

Instead, you need to measure from the animal's back to the ground. In the case of horses, the standard is to measure from their withers, a bony ridge between their shoulder blades, right at the base of the animal's neck. (In fact, this is the standard for measuring dogs, too, so we could use it to get Winona's height!) Unfortunately, MLP ponies aren't rendered with withers, so we have to estimate. The point on the back where the neck and back meet is good.

Using the above screenshots, this puts Cheese Sandwich at 2.9ft and Pinkie at 2.04ft. In horse measurement terms, that's 8.7 and 6.12 hands high, respectively. (1hh = 4in)

In the real world, a "pony" is a horse breed which measures less than 14.2hh when fully grown, and more than 8.5-9.5hh. (Less than that is a "miniature horse," but the range is because of differing classification by differing breed registries.) With some margin for error1, that puts the MLP characters on the low end of "pony" height. (Or alternatively, they're little ponies! /pun)

I've been asked before why I assume the chart behind Cheese was in feet, instead of another unit or something entirely made-up. I refute the "made-up" argument with the fact that, honestly, there isn't that much worldbuilding in MLP, and creating a new unit of measurement would be unnecessary effort. Additionally, it would make the chart completely useless as a frame of reference to the viewer. Using alternative units, however, is argued against by simply presenting the results based on those other units:

  • Meters: Pinkie measures ~20hh. (Approximately 1in shorter than the tallest horse in the world.)
  • Decimeters: Pinkie measures ~2hh, 1/4 the minimum height for a pony. (This is less than 1ft tall.)
  • Inches, Centimeters: Even Big Mac is less than 1hh. (We're now on the scale of the blind bag toys.)

  1. Sources of error:

    • Finding Cheese's withers in the first image is difficult, since he's facing the camera.
    • The withers are actually slightly higher than the rest of a horse's back, but MLP ponies don't have one.
    • Comparing the scale on the wall behind Cheese to Cheese's height pixel-by-pixel is inaccurate, since he is not flush against the wall. (This is also a problem when extending this pattern to others, as they need to be the same distance from the camera for it to work correctly.)
    • The Mane Six may-or-may-not be fully grown. There are certainly adult characters taller than them.
    • The pony-vs-miniature-horse distinction is based on what's normal for the breed, not an individual specimen. Pinkie's measurement above may be under the minimum for "pony," but she might also just be short.
  • Is there any indication that the height scale shown on that screencap is measured in feet? – b_jonas Apr 20 '14 at 9:58
  • 4
    @b_jonas, there is a section in my answer devoted to exactly that. If the scale is in any other commonly used real-world unit, then the entire world is at a ridiculous scale (in one direction or another), and if it's in an uncommon or made-up unit, then its presence is less than useless. – Brian S Apr 21 '14 at 3:46

    While you've accurately determined scale between an apple and the height of the Mane 6, it doesn't necessarily translate against anything "real world" as the question asked. You assume that a MLP apple is roughly 4". Why? For all anyone knows, it's actually 20" in Earth-measurements. – phantom42 Nov 25 '13 at 14:01

Most objects seen in Equestria could be arbitrarily big or small, and the show staff often play fast and loose with measurements. But one thing you can't change the size of is a musical instrument. If Octavia's cello was smaller than a standard cello, it would produce a different sound.

Her un-pony-like stance makes this a bit harder to measure, and Octavia may be smaller than the average earth pony mare, but it appears to suggest a height of about 60cm at the withers, or about 6 hands. This is only a little smaller than the 7 or 8 hands suggested by other methods.

    It depends on the atmosphere's composition. If Equestria's air contains a lot of heavy stuff like xenon or sulfur hexafluoride, a small cello will sound pretty deep. It'd make small-winged flight easier, too. – Gaultheria Jul 30 '17 at 4:20

In equestria girls human fluttershy is shown with a rabbit and if you compare witha scene of fluttershy with angel you can see that ponies are about half the hight of an average teenager.

It occurs to me that another possible source is the opening animation to the Equestria Girls movie, where the ponies are briefly seen morphing into their human counterparts (only one of whom is actually the same character...)

Equestria Girls side-by-side

The perspective and movement in this shot make a direct comparison harder, but let's estimate anyway.

Twilight Sparkle has the most normal stance of the six in both frames. Her height as a pony is about 110px to the withers and 225px full height, while her human form is about 350px. If we assuming her human height is 1.62 metres, the average for an American teenage girl, that makes her pony form about 50cm to the withers, or 5 hands; and her full height as a pony 1.04 metres, or 3 feet 5 inches.

This is smaller than the other estimates. There are several unproven assumptions in this method though. I still favour the cello method.

In the official blooper reel for My Little Pony: Equestria Girls – Friendship Games, the following scene appears which provides a pretty clear size comparison between ponies and humans:

Rainbow Dash riding Rainbow Dash

It is worth noting that the bloopers are non-canon, but they're from about as official of a source as you can get (officially released, fully-animated content from DHX), and I don't see any reason why the animators would alter the relative size of the characters just for this scene. Additionally, this size seems consistent with what has been suggested by the other answers to this question.

There is a video that finds the actual height of the ponies. They're about four feet tall.

  • 5
    Can you post a quick summary of their reasoning in case the video gets axed by Google off CopyrightViolationTube? :) – DVK-on-Ahch-To Jan 4 '14 at 21:42
  • Basically, it uses the "8 foot candy cane" theory. It uses pixel ratios and cross-multiplication to find Scootaloo's height (75.79cm), then it shows a different image with both Rarity and Scootaloo in it, and it uses the same strategy to find Rarity's height (120.24cm, or about 4 feet). – user21070 Jan 6 '14 at 2:08

So we now have 3 strong hints at the roughly 120cm (4ft) size, including the head. Assuming this is correct, Equestria has insanely high gravity - more than the gravity on Jupiter!

There's a video investigating that which I tried to debunk but ended up mostly confirming, see here for both the original video and my (hopefully more credible) calculations.

So we've calculated Equestrian gravity assuming 4ft size; but what if we try the reverse - assume Earth-like gravity (g=9.8m/s^2) and try to calculate size?

Using my previous gravity research and assuming Earth-like gravity, Spike's spectacular jump into the lava was merely 3 meters high! The highest point of the jump measures 16 Spikes, so one Spike is 300/16 = ~18cm, or 7". That puts mane 6 at just 25 cm or at about 10" tall, including the head.

Unfortunately I can't tell if it's the ponies that are really small or if it's the gravity in their world is so insanely enormous. But either way, the "human transported to Equestria" fanfics are not credible: the human would either be crushed by the enormous gravity, or turn out to be just too damn huge compared to the ponies.

If the latter is true, perhaps the human should try to hang out with dragons instead? They're more their size!

  • Megan, Molly, and Danny were human, but perhaps then Discord attacked, causing the inconsistent laws of nature and forcing the pony princesses to control the day/night cycle. – Cees Timmerman Oct 22 '14 at 16:18

darthbobcat attempted to answer this in a 2011 forum post, and found that they are quite small as real world ponies go. He based his measurement on the size of cows.

Applejack talking to Daisy Jo the cow, screenshot from S1 E4

Let me quote parts of that post (bolding mine).

Since the dawn of Friendship is Magic, we have known that our little ponies are, in fact, little. But how little? The problem has been what to use as a baseline. Trees don't have a set height. Items in their houses would, of course, be scaled to their size. Dog breeds, bunny breeds and cat breeds vary in size.

And then I realized my point of comparison. The cows that Applejack deflected from trampling Ponyville have the coloring of Holstein cattle. That means we know the breed!

According to Wikipedia, a Holstein cow, at maturity, is about 58 inches (147 cm) at the shoulder.

Where you measure the cow at the hip is roughly equivalent to the height of its front hoof to the top of its back. And Holsteins have a fairly flat back.

Applejack is [...] 27.6 inches (70 cm)

Now to put this in perspective. The Shetland Pony is the smallest horse breed in the world,

Rounding up, Applejack is the size of the smallest individuals OF THE SMALLEST PONY BREED IN THE WORLD.

So the answer is: they are very little ponies indeed.

Another one from the Equestria Girls movie, where Twilight puts her hand through the portal and her arm is transformed. Good luck getting an accurate scale from it, though.

I cross-referenced the data and compared 5 different sources. They all converge around 3' to 1 meter:

This is some impressive math. I have a hard time figuring out how big ponies are myself. As a cartoonist I go by how many heads tall. The mares and stallions all have started out using the same basic body shape, three heads tall. They have regular deer as seen in Filly Vanilli. The doe is four heads tall. Fluttershy's forehead brushes the doe's chin. Compare that height to the whitetail deer around hunting season that range from 62 to 87 inches.

These are the notes I scribbled here. click here for image, it was a little big

I compared it to this website. http://www.deertrail.us/minnesotawildlife/minnesotawildlife/whitetaildeer.html

I like to think this.

  • I think a regular mare is 4 feet 5 inches, more or less because not everyone is the same height.
  • I think a filly (the cmc for example) is about a foot shorter, at around 3 feet 5 inches, a little more or less possibly.
  • Fancy pants, Luna, Fleur de lis, Sassy saddles, Cadence, and other ponies like that are probably around 5 feet.
  • I think celestia would be about 7 feet including her horn.

I also made a picture and journal explaining the height of wings and horns. If you want to read the whole thing here is the link. This shows how big wings and horns are, while this one shows how big the ponies themselves are.

Just to shorten it, a filly's horn is 5-7 inches, an adult's around 9 inches, Fleur, Luna, Cadence, Fancy pants etc. have a horn of around 14-16 inches, while Celestia's is 21 inches. For the wings, a filly's is a little less than a foot at about 10 inches. For an adult pony, wings are 27 inches or 2.25 feet. Luna and Cadence's wings are around 33 inches (almost 3 feet). And Celestia's wings are a whopping 45 inches, which is almost four feet.

Hope this helped!

    You've started your calculations with "let's assume all the filly pegasi we see are 3 feet 6 inches". Why did you pick that? Why shouldn't we assume that they're all 600ft tall? – Valorum Mar 23 '16 at 19:28

The average MLP pony is about the size of a large domestic cat when aged to adulthood. Foals around the age of the CMC are about half that size. Stallions are slightly taller than mares, but no significant difference, to me at least. Now, we are going to look at Celestia's height. Celestia is two times the size of an average pony if I'm not mistaking it.

If what I'm saying is true, than even if I'm counting her horn, Princess Celestia is half the height of the average adult human being.

I know you are telling me 'ponies are bigger than that, deal with it', and stuff like 'but ponies are not cat-sized'. And yes, I know of Equestria girls bloopers and all that, and bloopers are not canon. And between us, I do not think that the 'humans' of Equestria Girls are not humans at all.

It's okay to have your own opinions, but don't pick on me because of my opinion.

Alright so here's my theory. It hinges on one assumption: That the environment is of roughly the same scale as an RL environment. From here, one can figure one of two sizes are correct:

  • Objects such as houses and trains are depicted as strictly to-scale, at which point ponies are roughly RL pony size (around human height, 6+ feet long, etc.)
  • Objects such as houses and trains are slightly chibi-fied for the cartoon format, at which point ponies are slightly smaller than people (~4ish feet tall, slightly longer, maybe 10 inches wide)
  • Any reason for downvotes? :( – RCIX May 1 '12 at 15:15

    I'd suspect it was because this answer doesn't really answer anything; it presents two equally likely theories. A good answer is conclusive. – Gabe Willard May 30 '12 at 22:11
