How To Measure Your Window For Shutters in Honolulu

Darren Wong

Indoor shutters in Honolulu are almost always sold on a square foot basis, so if you’re looking for a rough measurement for a price estimate, simply measure your window length and width, to the nearest ⅛ of an inch.

For Honolulu homeowners who are a little handier around the house, Sunburst Shutters Honolulu will teach you the right way to measure your windows for indoor shutters.

Measuring Square & Rectangular Windows for Shutters

Common square windows sound like the easiest ones to measure – and they are, compared to other specialty windows. But there’s still an entire process to go through to get measurements. Here’s what to do.

The Tools That You Need:

  • Metal tape measure

  • Pencil and paper

To start, measure the width (the left-to-right distance). Take a measurement across in three separate spots: as close as you can to the center, near the top, and close to the bottom of the frame. Mark down all of them, to the nearest ⅛ of an inch. After that, measure the length (vertical) – measure three times, one in the center, and one near either edge of the window as shown below.

We recommend taking three measurements in each direction because no window is a perfect rectangle. And because of the different types of shutter mounts different windows need, you might either need to record the absolute smallest measurement (for an inside mount), or the largest measurement (outside mount). Taking measurements in multiple spots makes sure you’re covered for every options.

Measuring Unique Shape Windows for Shutters

Windows that aren’t rectangular are the tricky ones to measure. Just as there’s no perfect square window, there’s also never a perfect octagon, circle, or arched window – which means that taking the right measurements can be problematic. For the best results, get a professional measurement (which our team is happy to provide for no cost). Other than that, these are the steps to measure most types of unique-shaped windows for shutters.

Measuring Rounded and Arched Windows for Shutters

Measure the width of the window at the flat bottom. Only measuring around the window opening, record to the closest ⅛ of an inch the width of the arch. To find the height, look for the halfway point of the window by dividing the width distance in two, then measure to the end of the rounded part of the window from that spot. Again, write it down to the nearest ⅛ of an inch.

Measuring Elongated Arch Windows

Elongated arch windows are almost like a cross between a circular or rectangular, with a flat, wide bottom and vertical “legs,” but with rounded corners at the top and a higher arch. So attack it exactly as that: an arch and a rectangle on top of each other. Measure the width like you would any other arched window, then take a measurement of the height of the legs (the straight vertical parts before the window curves into an arch). Last, measure the maximum height of the window from the middle of the width, subtracting the height of the legs. Like always, write down every measurement to the closest ⅛ of an inch.

Measuring Circular & Octagonal Windows

Full circle and octagon windows are some of the trickiest to get measurements for, as there can be a ton of tiny imperfections that can alter the shutter dimensions you may need. You might want to leave these windows to a professional.
