How To Measure Your Window For Shutters in New York City

Dennis Rooney

Indoor shutters in New York City are almost always priced by the square foot, so if you need a measurement for a price estimate, just measure your window length and width, to the closest ⅛ of an inch.

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

How to Measure Square & Rectangular Windows for Shutters

Typical square windows seem like they’d be the easiest ones to measure – and that’s because they are, relative to other uniquely shaped windows. But there’s still an entire process to follow to find your measurements. Here’s the process.

The Tools That You Need:

  • Tape measure

  • Pen and paper

First, measure the width (the left-to-right distance). Get a measurement across in three different places: near the exact center, near the top, and near the bottom of the window. Mark down all three, to the nearest ⅛ of an inch. After that, do the same for the length (vertical) – get three measurements, one in the middle, and one near either edge of the window like seen below.

You want to measure in three places both ways because no window is a geometrically perfect square. And depending on what kind of mount your shutters will need, you may either need to record the absolute smallest measurement (inside mount), or the largest measurement (outside mount). Recording measurements in multiple places helps make sure you’re covered for every options.

Measuring Specialty Shaped 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 perfect semicircle or arch window – which means it’s not as simple as getting a width and height. If you want the best results, get a professional measurement (which our team can provide absolutely free). Otherwise, these are the steps to measure the most common non-rectangular windows for shutters.

Measuring Arched Windows and Round Windows

Measure the width on the window’s flat side. Only measuring around the window opening, mark down to the nearest ⅛ of an inch the width of the arch. For the height, find the halfway point of the window by dividing the width distance in half, then measure to the end of the rounded part of the window from the point you found. Again, write it down to the closest ⅛ of an inch.

How to Measure Elongated Arch Windows for Shutters

Elongated arch windows look like a combination of a square window and a circular window, with a wide, flat bottom and vertical “legs,” but with rounded top edges and a higher arch. So imagine it like that: an arch and a rectangle mashed together. Measure the width like you would any other arch, then measure the height of the legs (the straight vertical parts before the window curves). Next, measure the max height of the window from the middle of the width, subtracting the leg height. Like always, record all of these to the closest ⅛ of an inch.

How to Measure Octagon and Circular Windows

Full circle and octagon windows are some of the most difficult to find measurements, because there can be a ton of tiny details that can change the shutter dimensions your window may need. We strongly recommend leaving these more difficult ones to a professional.
