Measuring Windows for Window Boxes When measuring your windows to determine the size of your window box needs, a good rule of thumb is to get a window box that matches the size of your window or one that matches your window plus your trim. This is especially true when you have a wide trim around your window which makes the window look bigger.

You can rarely go wrong by getting a window box that matches your window. However, when you get a window box that overhangs your window by a few inches this helps create the right balance of window box and window without the window box looking undersized or swallowed up. This is even more true if you have shutters, which tend to make the window look bigger than it actually is.

We generally recommend that you go inches larger than your window sill in these instances on each side. All of our listed sizes are for the base boxes not including the cap or trim on the top or edges.

Any additional trim that overhangs one of our window box planters is not added to the size of the window box. So for example, a 36" traditional box is built as a 36" box with a cap that overhangs about 1. For an out-swinging window, measure down 6 to 8 inches. Tip: Have the window box and brackets handy, already painted or stained.
