Pocket v Full Viewable Glass Size

[Windowsagogo]

I am looking for replacement windows for 40 year old windows that are under a porch so they've been protected and all wood. I can't seem to get a clear answer. I want as much viewing room as possible. Is the viewable glass area in a pocket install replacement windows a different size WxH then a Full install? if so how significant. I am trying to maintain as much glass as possible now that i have to replace and trying to maintain the beauty of the wood windows using the vinyl replacement.
Thank you

The answer, assuming you are using the same product for an insert window vs. full tear out, is pretty simple. It's basically 1.5" in total width and about the same in height (depending if you have interior stools or not). You are only removing the frame of the old wood window at that point (3/4" wood bucks) and installing stud to stud.

Keep in mind, you will need to re-trim the existing window interiors as a part of this process so figure on that additional expense and carpentry work as well.

There are things to consider when only doing a partial replacement when choosing between inserts , “full frame” and finned new construction windows. The latter 2 Are gonna give more viewable glass but they can change inward and outward appearances. Ideally you choose something that meshes with your other windows A good sales person could walk you through this , explain the pro’s and con’s of each and make a recommendation that fits your overall goals. I like continuity overall before glass space and this is something to consider when doing a partial replacement.
