Standard window sizes - how to specify

[MattCarp]

I am working to "finalize" a design in HD Pro '23.   At the moment, I'd like to make sure I'm using standard sizes in my windows.

 

I'm referencing the standard size charts here:  https://modernize.com/windows/standard-sizes

 

This chart specifies the rough openings for standard window sizes.

 

In HD, when I look at a window's properties, is the width and height the rough opening?   Or, do I add the rough opening values listed in the rough opening panel to the width and height?

 

For example, in my attachments, the window I have designed is 28"w x 48"h.   Using the chart, the closest size is a 2840 window, which specifies a rough opening of 32" x 48".  The rough opening parameters are 1/2", each side, top, and bottom.

 

I know that I generally don't need to be this precise, but, if I want to make sure my framing lines up with the required rough openings for standard windows, I think I need to just change the window width and height.   

 

(I was attempting to verify this by looking at a framing elevation, but I have not perfected the technique to view only the framing of the wall elevation.   In some tutorials I see a toolbar drop down for the visible layer set.  I don't see this in my version, and, the reference manual doesn't seem to indicate this.   I do a wall elevation camera, but when I deselect all the layers except for framing, my updated view is blank...)

Most standard/production type vinyl windows are actually slightly smaller than their stated size, so the rough opening is the window size. A 5/0 x 4/0 window (5'w x 4'h); would have a 5' x 4' RO. However, not all windows fit this. Some RO's are 1" over stated window size. As solver stated, check with your window manufacturer.
