How to Measure For Exterior PVC Shutters
Solid PVC exterior shutters are extremely versatile and can be installed in either a stationary position next to the window or with hinges to swing open and closed. The intended function of the shutters is used to determine the best approach for measuring. The following guide and video will help establish the best style, size, and configuration. Once ordered, PVC shutters are built to the specifications provided and shipped direct. Install PVC shutters using the assistance of our written instruction and how-to video.
Tools required include a steel tape measure, ladder, pencil and paper to record the measurements. Expect to spend about 5-10 minutes to measure each window.
Functional Exterior Shutters
Solid PVC exterior shutters, in conjunction with quality outdoor hardware, install to either side of a window opening to swing open and closed. Recessed window openings can accommodate shutters that nest inside, while shallow windows need shutters that close in front of the casing. When open, PVC shutters accent the appearance of the window and gives full access to the window. Closed, these exceptional exterior shutters can shade the window, provide privacy and protect from rain, wind or heavy storms. The fit in both the open and closed positions needs to be taken into account when measuring.
Stationary Outdoor Shutters
PVC shutters installed in a permanent position are purely for decoration. They mount with brackets at the top and bottom of each shutter. The necessary v-shaped Polycarbonate brackets and screws are included with the shutters for easy installation. Measurements for stationary shutters are more forgiving than for functional shutters, yet the goal is to always make them symmetrical to the size of the window. They should simulate the appearance the look of functional shutters, and can even be enhanced with the addition of dummy shutter hardware.
Measure PVC Shutters to Function with Hinges
Time needed: 10 minutes
Step to measure for functional PVC shutters that install with hinges
- Measure the window opening depth
If the dimension is greater than 1.25″ and you wish for the closed shutters to nest inside of the opening.
- Measure width:
For deep windows: measure from inside edge to inside edge. Subtract the amount needed for clearance. We suggest a 0.25″ on each side and a 0.25″ in between the shutters. Divide that measurement by 2 for the individual shutter width.
For shallow openings: Measure the width of the window exceeding the opening on either side by at least 0.5″. Subtract a small deduction for clearance (no more than 0.25″) and divide that measurement in half to calculate the individual shutter width. - Measure height:
For deep windows: Measure from the top of the window opening to the bottom of the opening. Deduct a slight amount for clearance (about 0.25″ at the top and 0.25″ at the bottom) to achieve the shutter height.
For shallow openings: Measure for the shutter height to overlap the window opening by at least 0.5″ on both top and bottom. Often, the height of the shutter will align with the outside of the casing. - Measure for an optional divider rail
Shutters can be made with a divider rail that creates top and bottom sections. Specify the division point for the divider rail by providing the measurement from the bottom of the shutter to the desired center of the divider.
If a custom location is desired, provide the measurement from the bottom of the shutter to the identified center of the divider rail.
For two divider rails, note the location of each from the bottom of the shutter to the center of each. - Select shutter hinges

Measure for PVC Shutters in a Fixed Location
- Measure width
Measure the window width from the far left of the trim to the same point on the opposite side. Divide that measurement by 2 for the approximate shutter width. Ideally, the width of fixed exterior shutter should equal half of the window to replicate the appearance operable shutters. - Measure height
Historically, shutter heights have aligned with the window opening, which can cause the shutters to appear short in comparison. Fixed shutters installed purely for aesthetics are more frequently made to the same height as the window casing. - Measure for an optional divider rail
Shutters can be made with a divider rail that creates top and bottom sections. Specify the division point for the divider rail by providing the measurement from the bottom of the shutter to the desired center of the divider.
If a custom location is desired, provide the measurement from the bottom of the shutter to the identified center of the divider rail.
For two divider rails, note the location of each from the bottom of the shutter to the center of each.
Outdoor Shutter Hardware
Operable exterior hinges are necessary to give PVC shutters the ability to swing open and closed. It is best to evaluate the various hinge options for installation at the same time window measurements are taken. Survey the available mounting surface and establish the necessary offset.
| Shutter Height | “Strap” or “Acme” hinges |
|---|---|
| If < 84” | 3+ hinges: top, bottom & center 1 lower support (shutter dog or wall bracket) |
| If > 84” | 4+ hinges: top, bottom & center 1 lower support (shutter dog or wall bracket) |
Shutter dogs restrain outdoor window shutters in an open position to either side of the opening. Tiebacks work in a variety of ways to lock and release the panels, with many in ornate designs to give the house added interest. Shutter dogs can also be used in conjunction with stationary shutters to add visual interest.
How to Measure for Arch Top Shutters
PVC shutters can be made with a curved top designed to match the contour of a round top window. Arch top exterior shutters require a springline measurement to define the slope of the curve.
Bahama Shutters
Tropical PVC Bahama shutters are designed to cover an entire window opening with a single panel. Record measurements of the entire window width and height as specified above. Exceptionally wide windows can be covered in multiple Bahama shutter panels.
Shutter Measuring Tips:
- Use a steel tape measure. Don’t attempt to measure with a yard stick or ruler.
- Employ an assistant to help with larger windows.
- Don’t assume similar windows are the exact same size. Check all windows to assure accuracy.
- A sturdy ladder is essential for safety when measuring tall or elevated windows.
More About Solid PVC
Exterior PVC shutters are milled to look and work like natural wood shutters, but with the resiliency of a synthetic material. The material is exceptional in both beauty and durability.
