How To Measure Your Window For Shutters in Boise

October 04, 2017

Plantation shutters in Boise are usually priced on a square foot basis, so if you need a measurement for a price estimate, simply measure your window width and length, to the nearest ⅛ of an inch.

For Boise homeowners who are a little handier around the house, Sunburst will teach you the easiest way to measure your windows to be fitted for plantation shutters.


Measuring Rectangular and Square Windows for Shutters

Common rectangular windows look like the easiest ones to measure – and they are, compared to other uniquely shaped windows. But you still have an entire process that goes into getting accurate measurements. Here’s what to do.

What You’ll Need:

  • Tape measure

  • Paper and pencil

First, measure the width (horizontal). Measure across in three different places: near the center, near the top, and near the bottom of the window. Mark down each one, to the closest ⅛ of an inch. After that, do the same for the length (vertical) – measure three times, one in the center, and one close to either edge of the window like shown below.

We recommend taking three measurements in each direction because no window is a truly perfect rectangle. And because you might need a specific mount for your window, you may need to get either the shortest measurement (inside mount), or the absolute largest measurement (for an outside mount). Taking measurements in multiple places helps make sure you’re covered for every options.

Measuring Unique Shape Windows for Shutters

Non-rectangular windows are the windows that can present a challenge to measure. Just as there’s no perfect square window, there’s no perfect semicircle or arch window – and that means that even if you get perfect measurements, you could still have issues. If you want the best results, get measurements taken by a professional (which our team can provide absolutely free). Otherwise, these are the steps to measure the most common unique-shaped windows for shutters.


Measuring Arch Windows and Round Windows for Shutters

Measure the width on the window’s flat bottom. Only measuring around the window opening, record to the nearest ⅛ of an inch the width of the arch. For the length, locate the window’s midpoint by dividing the width measurement 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.


Measuring Elongated Arch Windows for Shutters

Elongated arch windows look like a cross between a circular or square, with a flat, wide bottom and vertical “legs,” but with rounded corners at the top and a higher arch. So attack it like that: an arch and a rectangle put together. Measure the width as you would any other arched window, then measure the length of the legs (the straight vertical parts before the window curves into an arch). Last, find the max height of the window from the middle of the width, subtracting the height of the legs. Like always, write down every measurement to the nearest ⅛ of an inch.


How to Measure Octagon and Circular Windows

Circular and octagonal windows are some of the most difficult to measure accurately, as there are so many tiny imperfections that can change the dimensions of the shutters you may need. It’s usually best to leave these ones to professionals.
