General rule of thumb is number of inches away / 2 for the size of TV. If you typically will be watching from 10 feet away then 60" would be the way to go. If you'll be watching from 14 feet away, then you'll likely want at least an 83" TV. If people will be watching from 16+ feet away and you don't mind spending $5k on a TV then a 98" TV is the way to go.
