Measuring Your Windows For Shutters in Philadelphia

Holly Perron

Indoor shutters in Philadelphia are typically sold on a square foot basis, so to get an approximate measurement for a price estimate, just measure your window width and length, to the nearest eighth of an inch.

For Philadelphia homeowners who are DIYers, Sunburst Shutters Philadelphia will show you the easiest way to measure your windows for indoor shutters.

How to Measure Rectangular and Square Windows for Shutters

Common square windows seem like the easiest kind of windows to measure – and that’s because they are, at least compared to other specialty windows. But there’s still an entire process that goes into getting accurate measurements. Here’s the plan.

The Tools That You Need:

  • Tape measure

  • Paper and pencil

Starting off, measure the width (the horizontal distance). Measure across in three separate places: close to the center, near the top, and near the bottom of the window. Record all three, to the closest eighth of an inch. Then, do the same for the length (the bottom-to-top) – measure three times, one in the middle, and one near either edge of your window as seen in the diagram below.

Why do you need to measure three times each? Simply because no window is a perfect square. And because you might need a specific mount for your window, you may need to get either the absolute smallest measurement (inside mount), or the absolute largest measurement (for an outside mount). Taking measurements in three places ensures that your bases are covered.

How to Measure Non-rectangular Windows for Shutters

Windows that aren’t rectangular are where measuring can become extremely tricky. Just like there’s no perfect square window, there’s no such thing as a perfect semicircle or arch window – and that means that taking the right measurements can be problematic. To really get the best results, get a professional measurement (which Sunburst Shutters Philadelphia can do for free). Otherwise, here’s how to measure most types of unique-shaped windows for shutters.

Measuring Arched Windows and Round Windows for Shutters

Measure the width on the window’s flat bottom. Only measuring around the window opening, record to the closest eighth of an inch the width of the arch. For the length, find the window’s halfway point by dividing the width measurement in two, then measure to the top of the window from that point. Again, write it down to the closest eighth of an inch.

Measuring Elongated Arch Windows

Elongated arch windows look like a cross between a square window and a circular window, with a flat, wide bottom and straight “legs,” but with rounded top edges and a taller arch. So think of it exactly as that: an arch and a square combined. Get the width measurement just like you would a normal arch, then measure the height of the legs (the straight vertical parts before the window curves into an arch). Last, measure the window’s max height from the center, subtracting the leg height. Again, record every measurement to the nearest eighth of an inch.

Measuring Octagon and Circular Windows

Circular and octagonal windows are some of the most difficult to get accurate measurements, as there can be so many small imperfections that can alter the shutter dimensions your window might need. It’s usually best to leave these windows to a professional.
