Interior Design Fundamentals Practice Test

A curved transition between wall and ceiling is achieved with a coved ceiling. The defining feature is a concave curve where the wall meets the ceiling, which softens the corner so the ceiling blends into the wall rather than ending in a sharp 90-degree angle. This creates a smooth, seamless edge and can also help hide joints or gaps.

This differs from a vaulted ceiling, which changes the height and plane of the ceiling rather than focusing on the edge at the wall. The other two options describe lighting fixtures, not ceiling edge design, so they don’t address how the ceiling meets the wall.
