Is tiny Sam stronger than tiny Dean?

Only as much as full sized Sam is larger and stronger than his older brother!

On the same size scale, the brothers are as equal as they are in canon. Both receive the strength boon that borrowers get.

Compared to a human at the same size, they’re both around 12 to 13x stronger. With training and proper nutrition, they’ll be closer to 17x their regular strength. So if Dean wanted to, he could dangle Sam by the nape of his neck just as much as Sam does.

He just happens to be shorter, so it’s nowhere near as easy, ffs. Stop that, Sam!

Wait how can Jacob lift 40x his body weight when he is only around 1/20 th of his original weight/height? Please check my math but wouldn’t this mean he would be able to lift a human easily?

Actually, only his height is a 20th of his original size. Thanks to the square-cube law, his weight is much, much less. 

@torchmlp was nice enough to do the math out for us, and they were curious about cursed Jacob’s strength compared to his weight, so they did the formulas out.

We know now that Jacob weighs about as much as three crayons, and 40x his weight is equal to the vase he was lifting. Dean, of course, can lift this vase in one hand and trap Jacob in a fist without the kid’s knack doing him a bit of good. 

If we took cursed Sam, cursed Dean and cursed Jacob, the difference in their strength would be that together, Sam and Dean at a regular height would be able to pick up the Impala and walk away with it, while Jacob by himself could do the same with even less effort. Just one kid. Walking away with that car (put it back!).

How many sprites (lets say the knights) would be necessary to win against the brothers in a tug of war? With and without use of wings allowed? Or just one?? (no point in mentioning Jacob, they’d probably need the whole village just to challenge his hand)

Well, lets see.

If smol Jacob can lift about 40x his weight, I’d say a regular borrower averages 10 to 15x. The brothers, being determined to keep physically fit, are likely around the 12 to 13x range. Once they get better nutrition, they’ll easily hit around 17 or 18x their weight in strength, if not more.

Really, the questions is: how long does it take the sprites to realize they should just start flying and lift the brothers off the ground so they can’t get any traction?

With wings, they’d just go with that route. Lift up the brothers while Jacob watches, unable to hide his snickering (Dean will get revenge on him, somehow). At least they’re good at dangling from a rope.

If they weren’t allowed to use wings except maybe to balance themselves, it probably wouldn’t take much for the brothers to knock several knights over, one by one. Sprites aren’t nearly as strong as one of the brothers. Poor guys would dig their heels in the best they could though. Then maybe have a few sparring matches with pine needle swords to make up for it.

May 25th excerpt:

Dean shook his head. “Sure, we’re stronger,” he agreed. “But our adopted mom, Mallory, wasn’t close to as strong as us or Walt.” He hovered a hand close to his chest, indicating her height. “She didn’t have as much luck as us or Walt when she got out of the house to get supplies, but she did manage to throw it up.”

Jacob stared for a second longer at the height Dean had indicated. Their adoptive mother was absolutely tiny. Sam and Dean were already small, but this woman couldn’t be much more than three inches by Dean’s measure. 

He tried to think about what he knew of the family they had back at that motel. He hadn’t heard much about them at all, and with a small shred of guilt Jacob understood why. They’d be protective of them; Sam and Dean were just like that.

April 24th excerpt:

Scar let himself chuckle briefly, a short sound that carried his pride with it. He remembered discovering that Sam held strength much greater than any sprite. It was one of his fondest memories, seeing his then-youngest student besting all of his veteran knights one by one in a test of strength.
