Drywall can generally support tile weight up to 4 pounds per square foot on walls. For anything heavier, such as large format tiles or stone, you'll need to reinforce the wall or use a backing material designed to support more weight. For shower areas or places with significant moisture, consider installing a waterproof backer board beneath the tile, as regular drywall may not offer sufficient support or moisture resistance for heavy or wet applications.
