Should I sand my frame or buy a custom storm door for an opening that's 1/8" too short?
You can spend an hour or two with a sharp utility knife, a saw, some sandpaper and a can of paint, or you can triple (or more) the cost of your storm door by getting a custom built one that's 1/8&quot; smaller than standard.
To be honest, though, an 80x32&quot; storm door is the nominal listing size - the actual door will probably be 79-3x4&quot; x 31-3/4&quot; and will fit quite nicely. Stop by your local storm door retailer with a tape measure in hand and measure the physical size. Or, ask the sales guy for the actual dimensions. Odds are good an off-the-shelf door will fit without any tailoring at all.
