What does a rough opening measurement typically specify?

A rough opening measurement specifies the dimensions from stud to stud. This measurement indicates the space that will accommodate a door, window, or other opening after the surrounding framework has been assembled. It ensures that there is enough room within the frame for the intended installation, considering both the structural components and the finish materials.

Stud to stud measurements provide the necessary allowances for the rough framing, including the thickness of the drywall or any additional materials that might be applied to finish the opening. This measurement is crucial for proper fitting and installation of the final product, ensuring the alignment and structural integrity of the wall system.

While other options may mention different types of measurements, they do not accurately represent the standard practice in construction for indicating rough openings. Therefore, the specification of stud to stud is the most appropriate and recognized standard for rough opening measurements.
