Throughout the movies, cartoons, comics and tv series Spider-Man is shown walking on, hanging from and swinging from all sorts of structures, surfaces, ceilings and walls.

I understand how he does this but what I don't understand is how structures that where never built to take the weight of a full grown human don't ever suffer. I once watched a plaster boarded ceiling fall off from the weight of a light being hung from it (rather then being fixed to the beam like it should have been).

Has this ever been addressed in any medium, has Spider-Man ever gone to land on something, or hang from a ledge that couldn't physically take his weight and then fallen? Has he ever crawled across an office ceiling only to find that polystyrene tiles held on a thin aluminum frame really isn't designed to take a humans weight?

    You kind of answered your own question there. "movies, cartoons, comics and tv series". It's make-believe for kids and not real

    His spider-sense tells him what's safe and what isn't

  • I've encountered a couple of instances where his web wasn't sufficiently well-anchored. This is pretty answerable.

I can't speak to Spider-Man's superhuman (and otherwise baffling) lightness, but I can certainly think of some examples where his judgement about the strength of the objects he's webbing onto has been lacking.

In the latest Spider-Man outing, Peter tries to swing through the trees like a latter day Tarzan, with limited success.

enter image description here

and in Spider-Man 2 (2004) he accidentally pulls the side off of two separate buildings.

enter image description here

This frame from Essential The Amazing Spider-Man #001 would suggest that he's not always successful at landing on things either.

enter image description here

These panels from Spider-Man - Matters of Life and Death #004 would strongly suggest that his spider-sense (which he's lost following an accident) are what gives him the ability to identify strong spots to web onto.

  • Thankyou this is what I was looking for any evidence of Spidey either mis landing, or falling because things gave way, or a reason why he always landed. Looks like it is mainly his Spidey Sense
