If you're trying to attract swallows, they like living in a house on a wire hanger, that sways in the wind. I think the swaying part would discourage sparrows, too. Same size hole, 1 9/16". No bigger, or blue jays and other predators can get in and kill the babies.
Oh, and never put a perch on, either. That just gives predators something to stand on while they try and peck through the hole.
