How to Measure Your Windows Before Ordering Blinds

You've decided on a style, on a colour and a display for your blinds - now it's time to measure up.

Here's a list of tips to make sure you tell NZBlinds exactly what we need to know so you get exactly the right product:

1) Use a steel measuring tape for accuracy and measure to the nearest millimetre.

2) Measure the width and write it down, then measure the drop and write it down, then double check. When measuring and ordering, width always comes first.

3) Double-check every measurement and check your windows for any obstruction (window catches, fly screens, handles, security stays for example) that may stop the blind operating properly.

4) Don't take you're own deductions. The factory will make the necessary allowances and calculations based on your measurements.

Here's your three options for measuring and hanging your blinds:

 

1) Inside Mount: The blind will hang inside the window frame. Width: Measure the exact distance across the window from the inside edge of the frame to the opposite inside edge. Measure in three places and use the smallest dimension. Drop: Measure the exact distance from the top inside edge of the frame to the bottom inside edge. Measure in three places and use the smallest dimension. Ensure that the window reveal is deep enough to accommodate the blind.

 

 

2) Outside Mount (on the frame): The blind will hang outside the window frame, flush with the edges of the window trim. Width: Measure the exact distance from the outside edge of the left side of the frame to the opposite outside edge. Drop: Measure the exact distance from the top outside edge of the frame to the bottom outside edge.

 

 

 

3) Outside Mount (with overlap):The blind will hang outside the window frame, overlapping enough to cover for maximum privacy and light blockage, and possibly room to stack the blind away from the glass. Width: Measure the exact distance from the outside edge of the left side of the frame to the opposite outside edge. Add at least 50mm for venetian blinds or 100mm for vertical blinds. Drop: Measure the exact distance from the top outside edge of the frame to the bottom outside edge. Add at least 50mm for venetian blinds or 100mm for vertical blinds (or half this amount if the bottom of the blind is at floor level).

 

Corner windows are a little more complicated:

1) You'll need to measure and note down A, the left width; B, the right width; C, the depth of the window (make sure to note if the left and right windows are different); and D, the internal drop (make sure to measure in four or five places and note down the shortest measurement).

2) Just as with regular windows, make sure you note down the placement of any obstructions and how much of the window depth they occupy.

3) Decide how you want the blinds to overlap in the corner:
