This is late as fuck, but wouldn’t it make more sense to draw a line through Twilight to the inside top edge of the door frame and calculate her height that way?

Ponies mouth has the right height to suck you  
Alicorn plot has the right height to not need a bucket.
 
Point.

After measuring many screenshots from ponies like Pinkie Pie and Rarity (who’s manestyles let you see the base of their heads), I’ve concluded that a normal mares head height is 0.95 times their ear height. Try it. That should make adjusting future measurements easy.

Last post, I promise. There’s just one last problem with all of your measurements as a whole… and it makes Starlight Glimmer sad when you do it.
 

 
Yeah, here’s the thing: all of your measurements are up to the tips of the ponies’ ears. Not often, but seldom do the ponies let their ears droop down the backs of their heads… kind of like cats when they’re upset. It artificially adds a few inches to each of their heights. The only way to accurately measure them is to do so to the tops of their heads—can’t measure to their hairstyles because what if a pony is bald? What if they have a wild, out-of-control mohawk that sticks up an extra foot? Horns are out; can’t use something that pegasi and earth ponies don’t have. The only way to measure is by the tops of their heads…
 
…luckily, in most cases, it’s made simple by the fact that most average-sized ponies in the show have heads that are perfectly circular in shape with the muzzle protruding from the front. For the various princesses… harder, but still doable by the same guideline.

Continuing from above, if you want to use the “Fluttershy-to-Angel” scale, you can do that, but the problem I have with this is that you assume for a fact that A) that’s Angel Bunny in the picture with human Fluttershy, and B) that Angel in that dimension would have the exact same height, weight, proportions and diet as the one in the ponies’ dimension. I’m not saying it’s not possible, I’m saying we shouldn’t base anything off of uncertainties. This is why I prefer to use the ‘candy cane’ scale. With this, we know one measurement for certain: the candy cane is “eight feet tall” (96 inches).  
How do you measure this candy cane? Straight to the top? At a slant? Up and around the crook?
Well, first of all, she says “an eight-foot-tall candy cane”. The bend at the top of the candy cane is not part of its height but its length, so that’s out. As for the other two, I’ve saved you the effort.

(Ripped from a 720p video from “Hearth’s Warming Eve”, upscaled to 1080p)
 
I’ve done most of the important math for you—the candy cane is sitting at about a 13.75° lean. If you measure along that angle from where it sticks out of the ground to the “top” of the candy cane, it comes out to 817.35 pixels high. On the other side, I measured the candy cane straight from the top of the candy cane to the two “corners” at the bottom of the pole; one measures 841 pixels high, the other measures 816… which is eerily close to the 817.35 we got measuring it along the slant, isn’t it? (In the measurements given in the link above, I use a median measurement between those two values from a 720p screenshot; upscaled to 1080p, it would come out to the same median value if you measured it here: 828 pixels.) Even still, the maximum difference between 841 and 816 in pixels per inch is…?  
Highest: 841 pixels ÷ 96 inches = 8.76 px/in
Lowest: 816 pixels ÷ 96 inches = 8.5 px/in
…look at that. A quarter of a pixel per inch, only a 3% difference. Certainly not negligible, but a far cry from the almost 10% deviation with the “human/door” scale.

…no. Just no. You immediately make your math worthless in three easy steps right out of the first panel.
 
  1. You measure the edge of the door frame to try and calculate the height of a human in the center of the doorway.  
  2. If you’re going to do the math, take pride in showing the actual numbers as well as your work instead of rounding to the nearest multiple of ten.  
  3. Your lines are thicker than your comprehension of the subject.
     
    Okay, let’s start from the top—average door frame height is 6’8” (80 inches) or 203cm. From the edge you measured, the door is 853 pixels high (though the protruding edge at the bottom is obscured by Spike’s tail) and Twilight is 696 pixels from the top of her head to her heels… but wait! If someone measures the door from the other edge, the door becomes 936 pixels tall—a discrepancy of over 80 pixels, almost 10%! If we measure by your standard:  
(Measured from far side of door frame)
853 pixels ÷ 80 inches ≈ 10.66 px/in
696 pixels ÷ 10.66 ≈ 65.28 inches (Twi’s height)
…by your measure, Twilight is 5’5¼” tall. Decently tall, matches up with your findings roughly. But if we measure using the other edge of the door frame which, while obscured by the lockers, can be extrapolated by the angle of the wall behind Spike:
 
full  
(Image above taken from a 1080p version of Equestria Girls, width cropped, height unscaled)  
(Measured from nearer side of door frame)
936 px ÷ 80 in = 11.7 px/in
696 px ÷ 11.7 ≈ 59.48 in (Twi’s height)
Suddenly, Twilight has shrunk down to below the five-foot mark by a half-inch!
 
And yes, before anyone comments and complains, I measure the “bottom” of Twilight along the heel of her inner foot, which roughly corresponds to the center of her shadow, which in turn would indicate the center of her mass. So since neither of these values are correct in themselves, we’re gonna take the two height values we have and average them out. 65.28 - 59.48 = 5.8… so let’s halve that, add it to the lower value. Voila! Human Twilight is now 62.38 inches, though to keep it concise, let’s put her height as 5’2½” (158cm)… with heels, of course. Without, she still seems to fall close to the earlier five-foot estimate.

So then. how tall s “Sunset Shimmer?”. in equestria girls. can anybody answer my question?.

3’2” vs. 3’4” vs. 3’6” is pretty inconsequential in the end. Margin of error just about covers it.
 
.97 to 1.07 meters for you heathens.
Trahzo

Alright, is taller than Diancie the Jewel Pokemon, underline Jewel! Unless Diancie goes mega than she’s a foot taller than Spike.

This one is my favorite one.  
Odd that it measures to the tops of the ears, though, but it works. I love how these actually-serious size chart analyses tend to turn up the same small range numbers.

The author didn’t take into account that Twilight got a little taller when she became an alicorn. The measurements for the princesses should all be a little bigger.

At least one other measurement doesn’t fit: if the fire ruby from “Secret of My Excess” is about 25 carats (5g), its size relative to Rarity makes her about 28cm tall.
 
If Rarity is actually 97cm the gem is somewhere near 1000 carats (200g). While “at least twenty carats” would remain technically true, it would be strange for someone who works with gems regularly to give such a bad estimate.
 
Of course this is a writing error. The point is that the scaling in the show is not rigorous. 100cm (as above) seems like a good typical pony height but I think 85-130 would be defensible.
 
If a normal pony were over 130cm, then Celestia would be larger than the largest earthly horses, which seems implausible.
 
If a normal pony were under 85cm, her toast would tend to land butter side up when knocked off the table, making her too difficult for humans to relate to.
