The thickness of drywall typically used for forming curved walls is 1/4 inch. This thinner drywall is specifically designed to be flexible enough to bend around curves without cracking. It is commonly used in scenarios where walls are not completely straight, such as in archways or decorative elements. The flexibility of this thinner drywall allows for smoother and more attractive curves, making it the ideal choice for creating those rounded edges in construction or remodeling projects.

Other thicknesses like 1/2 inch and 3/8 inch are generally used for flat surfaces where sturdiness is more important than flexibility. While 3/4 inch drywall is very sturdy, it is too rigid to accommodate bending without breaking, making it unsuitable for curved applications. This is why 1/4 inch drywall is specifically utilized in situations requiring curvature.
