How to measure the inside area of a skylight for a panel

General Information

  • Use a steel measuring tape and measure down to the nearest 1/8″.
  • Don’t be surprised if your windows aren’t perfectly square.
  • Measure all windows, even if they appear to be the same size.
  • Decide if you want your blinds installed within the window opening (Inside Mount) or on your wall/trim (Outside Mount). Most people use an Inside Mount for a neater look, but make sure you have enough depth to allow the product to fit. Use an Outside Mount when your opening is too shallow or when your window is significantly out of square.
  • Remember that inside mounts have deductions taken by the factory
  • Measure the Width in three places using the smallest width
  • Measure the Height in three places using the longest height

Measuring for INSIDE MOUNT:

Provide the EXACT window opening size. DO NOT TAKE ANY DEDUCTIONS. The factory will deduct up to a 1/2″ from the width you designate so your product will fit inside of your window.

Measure in 3 places (top, middle, and bottom) and use the NARROWEST measurement.

Measure in 3 places and use the TALLEST measurement plus 4″ for roller shades and the SHORTEST measurement for panels. Do not add 4″ for panels.

Measuring for OUTSIDE MOUNT:

Specify the EXACT WIDTH and the EXACT HEIGHT you want your product; the factory will make your product the exact size you specify. Consider adding a few inches on the sides, top, and bottom for additional coverage. Be alert of any obstructions like a deadbolt or door knob.

How to measure the inside area of a skylight for a panel

** note: for skylights that open, you must remove the screen to get at the glass area

Step 1 –

step1_skylight Measure the width of the skylight by placing the measuring tape INSIDE the opening of the glass framing as seen in the photo.  Be sure to add the length of the tape shell.  Give exact measurements and be sure to place the tape so it is flush with the outer edge of the glass framing.  Take at least three measurements of the skylight’s width.  Measure the width at the top, middle and bottom of the skylight’s glass framing and write down the SMALLEST measurement.

Step 2 –

step2_skylight Measure the length of the skylight by placing the measuring tape inside the opening of the glass framing as seen in the photo but measure to the outer edge of the as seen in the first photo.  Take at least three measurements of the length.  Measure the openings length on the left side, the middle and right side of the glass opening and write down the SMALLEST measurement.

Most windows are not square so do not be alarmed if you are getting different measurements for each of the lengths and widths. That is why we have you measure at least three time for both the length and the width. We want the smallest measurement for both so when you reverse the panel it will fit in the opening. There are often gaps between the panel and the skylight trim because the windows are not square and to ensure it fitting in both the summer and winter mode. You have reduced the exposure of the glass by about 99% which is your objective for installing the panels.

The panels are held in by U & J Channels that we cut to size for you. We make the deductions for the channels when making your panels. You can see photos of the U & J Channel installed. Once the channels are screwed into place the panel will be inserted into the U channel, then grasp the clip on the end of the panel that is not yet in the J channel and apply enough pressure to lift it up and over the lip of the J channel and the panel will then be secured in place.
