Measuring Square & Rectangular Windows for Shutters

Common square windows look like they’d be the easiest kind of windows to measure – and they are, at least compared to other specialty windows. But there’s still an entire process to go through to get measurements. Here’s the plan.

Tools Needed:

  • Tape measure

  • Pencil and paper

First, measure the width (the horizontal distance). Measure across in three different places: in the middle, close to the top, and near the bottom of the window. Mark down each one, rounding to the nearest ⅛ of an inch. Next, measure the height (vertical) – measure three times, one in the middle, and one near the left and right edges of the window like shown below.

The reason you need to measure in three spots each direction is because no window is a perfect square. And because you might need a specific mount for your window, you might either need to record the shortest measurement (for an inside mount), or the longest measurement (outside mount). Getting measurements in multiple places helps make sure your bases are covered.

How to Measure Specialty Shaped Windows for Shutters

Windows that aren’t rectangular are the tricky ones to measure. Just as there’s no such thing as a perfectly square window, there’s no such thing as a perfect octagon, circle, or arched window – which means that taking the right measurements can be problematic. If you want the best results, get a professional measurement (which Sunburst Shutters San Antonio is happy to provide for no cost). Otherwise, these are the steps to measure the most common non-rectangular windows for shutters.

Measuring Arched and Semicircle Windows for Shutters

Measure the width on the window’s flat bottom. Measuring only the window opening, mark down to the nearest ⅛ of an inch the width of the arch. For the height, look for the window’s halfway point by dividing the width distance in half, then measure to the top of the window from that spot. Again, record to the closest ⅛ of an inch.

Measuring Elongated Arch Windows for Shutters

Elongated arch windows are almost like a cross between a circular or rectangular, with a flat, wide bottom and vertical “legs,” but with rounded top edges and a higher arch. So attack it like that: a rectangle and an arch put together. Measure the width like you would a normal arch, then measure the height of the legs (the straight vertical parts before the window curves). After that, measure the window’s maximum height from the center, subtracting the height of the legs. Again, record every measurement to the nearest ⅛ of an inch.

How to Measure Circular & Octagonal Windows

Octagonal and circular windows are some of the most difficult to get measurements for, because there are a ton of tiny features that can change the dimensions of the shutters you might need. It’s usually best to leave these more difficult ones to a professional.
