Where should you measure for the rough opening of a window or door?

Measuring for the rough opening of a window or door typically involves taking measurements at the center point to ensure accuracy and consistency. By measuring from the middle, you account for any potential variations or irregularities at the edges of the framing that could affect the overall dimensions. This centralized approach helps in accurately determining the required size of the rough opening, ensuring that there is even clearance and space for adjustments during installation.

While measuring from either side is possible, it may not provide the most accurate representation of the required opening if the frame is not perfectly square or if there are any discrepancies. The center measurement serves as a reference point, making it easier to adjust for those variations and ensuring that the window or door is properly aligned and functional once installed. This correct approach minimizes the chances of errors in the framing process and contributes to the overall quality of the installation.
