Venetian blinds come with mounting brackets and hardware. Screws for installing the brackets are usually included in the package. There will be two end brackets – they hold the headrail of the blind in place. If the brackets are marked left and right, you should install them accordingly. There may also be support brackets. Install them along the width of the blind.
Note: Looped lift cords can be a hazard to small children and pets. Follow manufacturer’s instructions on how to childproof your blinds. As an alternative, cordless blinds are available.
Before you buy your Venetian blinds, be sure you have measured correctly.
The first thing to do is to make sure the window is deep enough to hold the brackets for the Venetian blind. If it isn’t, you’ll need to mount your blind on the outside. If it is, the next step is to determine the position of the Venetian blinds. Decide if they will be mounted on the inside or the outside of the window frame. Inside mounting will look more customised, although outside mounting will provide better control of lighting.
For inside frame mounting, measure the width between the points where the brackets will be placed; top, middle, and bottom (most windows are not perfectly square). Record the narrowest of the measurements you receive. Now, measure the length of the window (starting from inside the top of the window frame to the windowsill). Again, one side may be longer than the other. Record the longest length measurements, to the nearest 1/8 of an inch.
For outside frame mounting, you’ll need to measure the overall width of the area to be covered. To get this measurement, add at least 1-1/2 inches to the width of the window opening. Two inches (one inch one each side) is even better to block light.
Now measure the length. Start measuring from where you plan to mount the headrail down to where you want the blind to end, which is usually just below the sill. The brackets to hold the headrail will go straight into the wall. You may need to buy and install wall anchors to secure the brackets if there is no stud there.
1. Determine if you want inside or outside mounting, and measure your window accordingly.
2. After you have purchased the correct size of Venetian blinds, remove the window stop from the top of the window on the window casing.
3. Screw the brackets that came with your blinds to the side window casing at the top, using either two or three screws per bracket.
4. With the wand on the left and the lift cord on the right, slide the Venetian blinds into the brackets you just installed.
5. Once you have the Venetian blinds in place, secure the caps over the brackets.
6. If the blinds are too long, remove the slats from the bottom of them, as this should help to get them to the appropriate height.
