Dragons are the quintessential monster. They're massive in size, incredibly intelligent, can breath fire, and have wings. They're iconic the world over, and are in the very name of "Dungeons & Dragons". The very sight of one should send a bone-chilling panic into any would-be adventurer.
Yet I've noticed in the fifth edition of D&D, dragons have surprisingly low strength. Looking through the monster manual and I see dragons with STR of 19, 23, 26, 22, and so on. The strongest dragon I found only had a STR of 30. Now, this may seem like a high number, but when compared to the average human strength of 10, this means that the strongest dragon is only three-times better?
If we think about why dragons seem so dangerous and scary, it's easy to imagine a dragon being able to crush, chomp, or smash a human with little to no effort. In Lord of the Rings, for example, it took an entire village, equipped with a special ballista, and the fact that the dragon had a hole in his iron-hard scales, to defeat it. Yet in modern RPGs we see a watering down of dragons; an artificial nerfing to human levels to allow for PCs to triumph and defeat them with no more than four to six humanoids.
Dragon's True Strength
All of this got me thinking about what the "true" strength of a dragon should be. How much can they carry? What is their STR score? Here's what I came up with...First a disclaimer: It should be said that yes, there are many different sizes of dragons throughout mythology, and that with that there will also be a wide variation in strength. So, to keep things simple, I'm going to stick with Smaug, the dragon from LOTR; since it's so iconic and seems like a fairly "medium" dragon.
To start, since dragons aren't actually real, we need to find a real-world comparison. I've chosen to look at elephants, since they're both large and are actually a thing. The average elephant is about 20 feet long and can carry 9000 kgs. Compared to a human of 6ft tall who can carry 90 kg (200 pounds) on their back. This means elephants are over three-times longer than humans are tall (foot to head), but can carry 100 times more weight.
Now let's look at this scaled image of Smaug the dragon.
I measured the human to be 66 pixels tall, and Smaug to be 620 pixels tall (from bottom of his front foot to head). One could easily argue that I should have measured the dragon length-wise (including or not including his tail), which would easily make him even larger in pixel count.
So, what do the numbers tell us? Well, for one, Smaug is over nine-times larger than the human; and if we use elephants as a guide, then he'd be able to carry up to 27,900 kg. That makes him an astounding 310 times stronger!
Conclusion
If an average human strength in D&D is 10, then in reality dragons such as Smaug should have a STR of 3,100. Incredible! In fact, it's kind of mind-boggling to think about. However, it makes a lot of sense, as well.For one, as I stated earlier, dragons should be damn-near unstoppable. They live for ages, are colossal in size, are smarter than humans, and breath fire! The idea of an entire kingdom, with torches & pitchforks in hand, marching up a mountain to a dragon's perch to take them on seems so much more epic then some rag-tag band of adventurers.
Second, based off their sheer size, they should be able to crush humanoids like humans can crush cockroaches. So, having a near god-like strength works well.
