If a rough opening for a window is listed as 2'-10" x 3'-4", what is the actual height of the framed opening?

To determine the actual height of the framed opening for a window with a specified rough opening size of 2'-10" x 3'-4", it is important to understand what each dimension of the rough opening represents.

The dimensions given, which are typically stated as width x height, indicate that 2'-10" is the width of the rough opening and 3'-4" is the height. In this context, rough openings are created to allow for the installation of windows, and they generally need to be slightly larger than the window frame itself to accommodate any necessary framing materials and provide room for adjustments.

The height of the framed opening is simply the second dimension provided in the rough opening description. Therefore, when we look at the size given, the height measurement is accurately reflected as 3'-4", which is the correct choice. This height allows for the proper installation of the window itself and ensures that the framing fits appropriately within the overall structure of the wall.
