I have a ceiling that is 16’x20′. How many 4’x12′ sheets 5/8 thick of drywall are needed to cover my ceiling?
Thanks for your question. If you have a 16×20 room that gives you 320 sq feet. You will then divide that by 48 sq ft which is what a 4×12 sheet will cover. This will result in you needing 7 sheets to finish your ceiling. For more information you can always visit our drywall estimator page.
