Large Size Squeezing into Tunnel

[RaizielDragon]

Can a Large-sized creature Squeeze into a 5'x5' tunnel, without using Escape Artist checks?

I'm thinking not. The rules for Squeezing seem to indicate that you take up half your normal space. So if a large-sized creature (10'x10'x10') were to Squeeze, they would still take up a space 5'x10'x10'. So they can squeeze into a 5'-wide roofless alley (essentially turning sideways and still occupying 2 squares worth of ground space and extending a total of 2 squares into the air), or fit under a 5' ceiling (essentially laying down and still taking up 10'x10' area of ground space), but they couldn't squeeze into a 5'x5' tunnel space, even if they did have room to stretch out into 10' worth of space (2 squares).

Is that correct?

No, he can squeeze in just fine. PF spacing is essentially 2D; it's a square grid, not a cube grid. A lot of people use 5ft cubes to make sense of aerial combat but that's just extrapolation.

The thing is that while everyone takes up multiples of 5ft squares, heigh isn't defined in those increments. There are large creatures that are 5ft high (horse) and medium creatures that are >6ft high, and large creatures that are 14ft high (troll), although trolls tend to be hunched over.

The squeezing definition itself doesn't go into height anywhere, so the strictly correct answer is "rule doesn't exist". Not a very satisfying answer perhaps?

You could extrapolate and apply squeezing penalties to people taller than the ceiling height; in that case typical humans (>5ft) would be squeezing in the 5ft high tunnel just like a horse (>=5ft but 10ft wide), while typical dwarves would be fine. A troll would be both too wide and too tall and therefore would have to roll Escape Artist to squeeze in.

Hm. I did see that it only mentioned squeezing with respect to width. I just assumed this translated to height as well.
