Help please with title. Is this a Bradbury short story?

Friendly alien visitors from space establish contact with earth people. Want to land. Earth people set up big welcome for their arrival at a designated landing field. Lovely weather, green field, sun sparkling on morning dew.

Alien ship comes into land in field, find themselves sinking into swamp and drowning, think they've been tricked by earth people.

Earth people can't see them, turns out they've got each other's size wrong. Alien ship is mere inch or so long and is landing in minute puddle caused by overnight dew.

Reminiscent of the Twilight Zone episode, "The Invaders," but not it, and doesn't sound like any of Bradbury's. See instructions posted on your other story query.
