In my experience using height for radius works, for example if you have a 20 ft high ceiling then the coverage for one speaker would be 40 ft diameter circle (around 1200 sq ft). Of course overlapping 5 ft has never killed anyone, but this really depends on the power of the speaker, I usually deal with 70v speakers tapped at 16 or 8 watts depending on how many speakers I put on one amplifier and the output wattage of that amplifier.
