Character mistake: Near the end of the movie, Charlotte says she doesn't have the strength to climb down into the crate. Two seconds later, she climbs down to comfort Wilbur, then climbs back up. Even if she couldn't go all the way to the crate, she was low enough that Wilbur could have carried her there himself.
