Make The Dick Bigger – A furry guide to penises

It’s a running gag amongst the furry world that we’re all size queens, and I’m no exception. At least when it comes to art, the sizes of real penises are really not an issue as any sane person will tell you, with a lot of the big dick pics you’ve seen on the internet being badly photoshopped to the point of being comical. It makes you wonder how they could get erect without fainting.

In the furry world though, we’re really trying to deal with fantasy, and not reality. In fantasy, everything appears smaller than it really is, volumes aren’t considered quite so clearly and we have to do a bit of addition to make things look right. When drawn, a 5 inch penis can start to look comically small on anything that isn’t a small character, and starts to stand out immediately. Why is this the case?

It can get a bit more complex with individual animal attributes, but for now, we’re going to focus on the body type of the character in question, with some examples. The body types that we use in furry artwork are exaggerated and flawless, and a large amount of the male characters come under two categories:

  • Athletic, perfectly toned males that fill the dominant or top role in images
  • Curvy, sleek femboys that fill the submissive or bottom role in images.

It gets more complex with dad bods and bara, but these two tropes are the main furry ones and likely influence the majority of it. So let’s take a look over these in detail

The athletic tops

I’m going to provide a popular image drawn by wolfy-nail here as I think it’s a perfect example for this trope, along with pretty much all the males that wolfy-nail draws.

You can clearly see the widened bone structures, muscle placement, and of course the dick and ball size that we’re talking about in the article. These males are usually drawn to be very large in size too, such as being anywhere from 6’5” to 8’5” tall, which also effects how big body parts such as penises are going to have to be in dimensions. As you can see quite clearly, the ballsack typically makes up the side of a large closed fist, with the knot typically maintaining similar or the same girth. It makes sense, you want them to match the size of the shaft, and there’s always a fetish involved for letting the balls touch when the dominant male has a pair that is far larger. At least that’s how it is for me, there’s something really pleasing about the idea of getting wrecking balled from behind while getting fucked.

If you lay the shaft down against the character’s body you would be able to notice that it would reach up to the diaphragm area on this male, if not beyond, making it about forearm sized (if not 1.25x a forearm) in length. As a knotted shaft the girth is thinner away from the knot, but typically on large males this often gets drawn as wrist or forearm width. A large penis is commonly shown in humans as reaching up to belly button height, this extends twice beyond that. So just how big is this wolf dick in the image? Well seeing as we assume it to be forearm length we can use some mathematics and proportions based on the height of the character to figure out how long it is.

At the forearm size assumption we can presume it’s 1/7th the height of the character in furry art, which makes proportions exaggerated. At the 1.25x we could say 1.25/7. So let’s map that out into heights and sizes:

  • 6′ Tall character: 1x forearm = ~10.3 inches, 1.25x forearm = ~12.9 inches
  • 7′ Tall character: 1x forearm = 12 inches, 1.25x forearm = 15 inches
  • 8′ Tall character: 1x forearm = ~13.7 inches, 1.25x forearm = ~17.1 inches
  • 9′ Tall character: 1x forearm = ~15.4 inches, 1.25x forearm = ~19.3 inches

Now that’s one big boy, as you can see the size increase is relatively linear with height, but you may wish to take care to make sure your character’s dick is going to fit realistically (with some flex) into another character. As a rule I’d recommend not breaking the 20 inch dick length barrier, but I’ll go into this more in detail in a bit.

How wide’s that dick? Well, you can eyeball it and see that it’s about three times as long as it is wide on the thin shaft segment, so that’s going to be a heck of a girthy shaft to take, you’re looking at anywhere from 3 inches on the 6′ 1x to 8 inches on the 9′ tall 1.25x badass example. You may want to scale the numbers down to fit the idea in people’s heads, I’d recommend going no higher than 5” in girth (diameter, not circumference). In terms of volume, remember that 3D shapes obey the square-cube law, so increasing any single dimension makes it larger not linearly, but extremely exponentially. Remember, your victim’s organs need room too in there. Here are some suggestions for dick sizes for your next daddy wolf (The lengths are also applicable to human penises! But I’ll have to go over equines separately):

  • 6′ Tall: 10-12” Length, 2.25-2.5” Girth, 2.75-3.0” Knot
  • 7′ Tall: 12-15” Length, 2.5-2.75” Girth, 3.0-3.25” Knot
  • 8′ Tall: 13.5-17” Length, 2.75-3.0” Girth, 3.25-3.5” Knot
  • 9′ Tall: 15-19” Length, 3.0-3.25” Girth, 3.5-3.75” Knot

You might notice that the girth is not represented as high here, while you might find bad dragon toys like Cole that will put a much bigger girth compared to length. However, this is for artwork and perhaps roleplay, and furries ultimately have a big depth fantasy, with less of an idea about just how wide they can stretch without bumping into the bone structure of their body. That being said, these girths are nothing to sniff at, although even the largest dimensions listed are actually possible to take by a human being, with a large amount of training and practice. It’s just a matter of extending the belief of the viewer/reader for long enough to think that with adequate training either they or someone else could handle such a thing.

A small note on equine shafts

Equine shafts are typically drawn 4-4.5x as long as they are wide, and you will want to take care to not make them excessively long. The lengths given above are actually a good guideline, although you may wish to choose the measurements on the larger limit for equines compared to the shorter ones. You can add a couple of inches to the length and then adjust girth appropriately if you want a bigger size, but you don’t want to go more than that. An example would be a 7” Tall zebra with a 15” shaft, with a 3.25-3.75” girth. Sounds good to me, I don’t know about you.

The femboys

Zeta-haru has got a good art piece to use as an example here, and you can clearly see how femboys are typically drawn with simplified, toony dicks, with fewer veins and relatively clean curves. It’s swept forward in the pose, but normally these femboy penises will reach up to belly button and a bit beyond, not so much as to draw a huge amount of attention. After all, in this case, the penis is more of a handle than a focal sex object on the submissive males of the fandom, with a lot of focus going towards the butt area on femboys. Too small though, and it starts looking shrunk as if by hormones, meaning that your average furry femboy is drawn as decently well endowed. As a rule, 6-10” dicks on your femboys should make sure that they’re going to look pretty decent while they’re getting their ass rammed by a larger male. You should also notice the coinpurse sized sack on femboys, it’s designed to contrast with the larger males in the previous category, and makes for some sweet balls-deep images.

How much dick can furries take?

Well, anally, a surprising amount! The rectum is not so large, but the sigmoid colon can be straightened out to create a hilariously long section of internal tissue to ram things up into, and unlike misconceptions it’s pretty damn durable and stretchy, which any XL Chance owner will inform you of. You start bulging out after about 10-13 inches of shaft going into your body, depending on how tall you are, this is because the sigmoid colon is a 3D shape that wraps behind the pubic bone and then moves out to near the surface of the abdomen.

Around this point the shaft has worked its way to being close to the surface, so you get the visible bulge. How prominent it is depends on the firmness of the object moving inside as well as the girth of it, which is why Bad Dragon Chance dildos are so effective at it, with the broad, blunt tip that is pretty resistant to being squeezed near the surface of the abdomen. You can actually keep going for another 10 inches or so after this point if you don’t mind traversing the sigmoid in its entirity and working up the colon, but there is a right angle that is impossible to pass with a rigid body at the transverse colon, where you can go no farther.

How deep can you get then? About a couple of feet inside you, actually! It’s not a straight tube, there are bends and curves that increase the length, and all in all you probably don’t want to exceed 20 inches at the most extreme end, which is why I mentioned 20 inches as a limit for dick sizes on furry characters, so long as you want to have them be relatively realistic to fuck.


I’m looking forward to seeing more belly bulge capable wolf doms though, that excites me.


  1. wow… That is probably the most indepth description on the subject i have ever seen. It’s kinda impressive. I applaud you. plus When you said about belly bottom height I just realised that’s me so thanks. It has made my day 😉 uwu
