What thickness drywall for ceiling?

What is the best thickness drywall for a ceiling? 5/8-inch drywall is the most common thickness used for ceilings in residential homes but there are some cases where a thicker one may be required. In kitchens and other areas where heavy appliances are present, it's probably best to use either 1/2-inch or 3/4-inch drywall rather than the lighter 5/8-inch variety. In addition to weight bearing considerations of individual rooms applying to sheetrock, thicker alternatives are recommended for ceilings used in commercial or other high-traffic locales. If in doubt about the appropriate thickness for your ceiling, always consult a professional who can make calculations taking into account all its structural requirements.
