How To Measure
1. Getting precise and accurate measurements is the first step towards a perfect shutter fit.
· Always measure with a new metal tape measure
· Always measure to the closest mm
· Measure all windows, even though they appear to be identical
1.2 Determine the squareness of window
· Measure diagonally from corner to corner.
· If the difference between the two diagonals is greater than 6mm, a Face Fit L Frame or Recessed Z Frame is highly recommended.
2.1 Measuring recessed (in) L and Z Frame fit
Plantation Shutters Z Frame
· Width – take three measurements at the top, middle and bottom of the window opening.
· Drop – take three measurements at the left, center, and right of the window opening
· For recessed fit, provide the smallest width and height measurements.
BLADES – CLEARVIEW TILT ROD
Size: 89 mm
Minimum Depth: 50 mm
* For some circumstances, a window depth of less than 50mm may be possible by using a mid-rail positioned at the handrail location. If there is a window winder that obstructs the bottom frame, a 3-sided frame (without a bottom frame) may be an option.
If you are not sure, please contact us with a photo and we will advise if it is possible or not.
2.2 Measuring L frame Face Fit (out)
· Width – take three measurements from the edge of the architrave to the edge of the architrave at the top, middle and bottom on the window frame.
· Drop – take three measurements from the top of the architrave to the bottom of the architrave at the left, center, and right of the window opening
· For Face Fit L Frame, provide the largest width and height measurements.
*You need at least 25mm of flat surface to mount your shutter frame. If the architrave is over 70mm, then 65mm ML (medium L) frames are needed. otherwise SL (standard L) frames work better.

3.1 How To Measure Your Mid Rail Position
Z Frame Shutters
· Mid rails provide strength to your shutters and allow you to operate the top blades independently from the bottom blades.
· Panels over 1800mm (basswood) or 1600mm (PVC) require a mid-rail for structural support. Warranty coverage may be affected if a mid-rail is not included.
· Extra charges may apply if more than one mid rail is needed within 1800mm.
· The most common placement for a mid-rail is in the exact center of the panel.
· It is also common to place the mid rail at a natural break.
· For recessed fit L or Z Frame, measure from the bottom of the inside of your window frame to the center point of the desired location of the mid rail.
· For face fit L Frame measure from the bottom of the architrave to the center point of the desired location of the mid rail.

3.2 How to measure your T-posts position
· The maximum individual Panel Width is 950mm for basswood and 750mm for PVC. For larger windows T posts can be used with any frame type where the size of the window requires three, four or six panels etc. They are used to divide windows vertically to match window design and cover large spaces.
· When ordering your shutters, you can choose Standard Panel widths – all panels are made equal sizes or ‘Custom’.
· Below are measuring instructions if you choose custom sizes.

4. Corner Window
4.1 Before the measuring
Please check that you have a minimum recess depth of 60 mm on your windows. If you have obstructions, check the depth is 60 mm from the obstruction out to the edge of your window recess.
The following measurements are based on a Recess L Frame (inside fit), if you have any questions, please do not hesitate to contact our shutter expert. When completing your order, don’t forget to select your frame option (4 sides or 3 sides).
4.2 Check your Corner
Check that the angle in your corner window is 45 degrees or 90 degrees. When you order you’ll leave the corner degree in note. If you’re not sure, please contact us.
To check 45 degrees angle：You can grab a notebook or paper. Place the notebook or paper into the corner of your window. If both sides are flush with your window then your angle is 45 degrees.
To check 90 degrees angle: You can hold up a notebook or paper into the corner of your window and if the notebook or paper fits closely you have a 90 degree corner.
4.3 Measure the widths
Measure the inside width of your recess for your
Left Window: Start inside and on the very edge of the top left hand recess (Point A), measure to the top middle corner (Point B), then do it again. Measure the distance between the bottom left hand recess (Point A) to the bottom middle corner (Point B). Please record the smaller measurement.
Right Window: Start inside and on the very edge of the top middle corner (Point B), measure to the top right hand recess (Point C), then do it again. Measure the distance between the bottom middle corner (Point B) to the bottom right hand recess (Point C). Please record the smaller measurement.
Do not make any deductions for the corner post — we will make the necessary adjustments during production.
4.4 Measure the Heights
Please measure the inside heights of your recess left and right windows.
Take measurements from top to bottom on the left, in the middle and on the right for each window. Please record the smaller measurement.
4.5 Measure the midrail positions
4.6 Measure for your T posts (3 or more panels per window)
If your left or right window with 3 or more shutter panels, you will need to measure for your T Post(s). Start from the left inside edge or corner across to the middle point where you’d like the T Post to sit. If you have another T Post, start from the left edge or corner again. If you’re not sure, please contact us.
