Starting Point: What Do I Need To Install Venetian Blinds?

Spotlight's venetian blinds include all the screws, brackets, installation instructions and other hardware necessary for installation. To complete your venetian blinds installation you will also need:

  • Measuring tape: Use a metal tape measure for any blind DIY jobs, as fabric dressmaking tapes can be prone to stretching and are more difficult to keep level.
  • Pencil: A sharp HB or 2B grey lead pencil is perfect for marking the venetian blind bracket positions.
  • Electric Drill: The powerful nature of an electric drill is recommended for easily drilling holes for screws. The addition of an impact driver attachment for installing the screws will ensure they are fully secured.
  • Step Ladder: Safely reach the tops of your window architraves with a step ladder for all your measuring, marking and bracket installation processes.
  • Screwdriver (Phillips Head): A screwdriver is essential if you're not using a drill impact driver attachment to screw the brackets into your window frame.
  • Spirit Level: A spirit level will provide reassurance that your brackets are perfectly aligned and level.

Guide To Measuring For Venetian Blinds

An important consideration when it comes to measuring for any blind is the mount type - do you want them on the inside or the outside of the window frame? Blinds installed on the inside of the architrave or window framing is known as recess fit. Outside mounted blinds, or those installed on or above the architraves are referred to as face fit.

Measuring for Recess Fit Venetian Blinds (Inside Mount)

  • Measure the width at 3 points across to check the window is square. If uneven, the narrowest of the 3 measurements is to be used.
  • Measure the height or "drop" at 3 points to check your window is square. If uneven, the shortest measurement is to be used.
  • Measure the depth of the window frame to ensure the brackets have enough space for installation, and that the blind will not interfere with window opening mechanisms.

Recess Fit Allowance: In order for your recessed blinds to correctly fit inside your window and operate smoothly, additional allowances or deductions must be applied. Our handy table below shows the deductions necessary for each venetian blind type:

Recess Fit Allowance Table

Fauxwood Venetian Blinds

minus 10 mm off the narrowest window width measurement

Timber Venetian Blinds

minus 10 mm off the narrowest window width measurement

Aluminium Venetian Blinds

minus 5 mm off the narrowest window width measurement

PVC Venetian Blinds

minus 5 mm off the narrowest window width measurement

Measuring For Face Fit Venetian Blinds (Outside Mount)

  • Measure the width of the window from the very edge of one side of the architrave to the other.
  • Measure the drop (height) from the top of the architrave edge to the bottom of the sill or frame.

Tips For Measuring Your Windows

  • Record all your measurements and window details in one spot for convenient reference.
  • Record all measurements in millimetres (mm). This will ensure accuracy of selecting and installing the right-sized blind for your windows.
  • It's a great idea to measure for both recess and face fix before heading to your nearest Spotlight store, especially if you're unsure about your preferred mounting type before you purchase your blinds.
  • If you choose to recess fit your blinds make sure that window locks, handles or winders will not interfere with the blind. Keep in mind that inside-mounted blinds will have narrow light gaps on either side due to the bracket location.

Step By Step Installation Guide

Now that you've got all the essential equipment handy, learned how to measure your windows and watched the video tutorial, let's review all the steps!

  1. Determine your mount type and measure your windows.
  2. Attach the brackets to the window frame. Use a grey lead pencil to mark a spot for two brackets - one on each side of the window - and make sure they're at the same height and depth on the window frame. Using a spirit level will make sure the brackets are in line with each other.
  3. Use a drill with an impact driver attachment so the brackets are firmly attached. If you don't have this attachment, drill the holes and then secure the brackets with the provided screws using a screwdriver. For all mount types the brackets should be oriented with the large holes facing downwards towards the floor.
    Note: Use the supplied masonry plugs if drilling into brick or concrete walls.
  4. Now you're ready to hang your venetian blind! For ease of installation, keep the blind furled up. Simply pick up the blind and slide the headrail into the brackets, ensuring the control wand and cords are facing outwards. Close the front cap on each bracket.
  5. Secure the cord to the window frame so it stays in one place and to ensure the safety of any small children that may be in the home. Use a screwdriver to attach the small cord bracket or cleat. Never use stick-on attachments - they're not as strong and could present a danger if the cord bracket comes loose.

Pro Tip: For wider width windows, it's recommended to use centre support brackets for additional strength and to keep the blind level. Depending on the width of your blind you'll find one or more of these brackets included in the venetian blind packaging.

Can I Cut Venetian Blinds To Size Myself?

It is possible to alter the width of venetian blinds to suit your windows, and adjusting the size is often an essential step if you wish to recess fit your blinds. Keep in mind that this is a very technical process! There are limitations on how much you can reduce the total blind width, as the control mechanisms are fixed within the headrail and will be compromised if too much is trimmed off. Check with Spotlight's in-store team as the cut back allowances vary across different brands, styles and sizes.

Pro Tip: When altering venetian blinds, equal amounts must be removed from both sides of the blind to maintain function, balance and aesthetic. E.g. If you've worked out that 60 mm total needs to be removed from the blind (including allowances) this equates to 30 mm from each side of the slats, headrail and bottom rail.

Altering PVC & Aluminium Venetian Blinds

To alter the width of aluminium or PVC venetian blinds, you will need a measuring tape, pencil, a hacksaw to cut the headrail and a slat cutter. These cutters are designed to easily trim each slat back to a consistent size, complete with a bevelled edge for a professional finish.

Altering Timber & Fauxwood Venetian Blinds

Cutting back fauxwood or timber venetian blinds yourself can be a tricky DIY process to undertake, and requires the use of specialised equipment like a drop saw to accurately cut back the slats. Experienced DIYers will stack all the slats together and bind them with masking tape while making sure the slats are all perfectly aligned. The tape helps protect the slats from splintering and chipping while they're being cut. Unless you have all the right equipment and are very confident in your DIY skills, it may be better to face fit this type of venetian blind if the ready-made size will fit without any trimming.

Venetian Blinds Installation FAQs

How To Shorten Venetian Blinds

At Spotlight, you'll find venetian blinds in a range of different drops or heights, including 137 cm, 150 cm and 210 cm. If your window height differs greatly from these sizes, it's a good idea to shorten the blind so the slats always look neatly stacked when fully lowered. Shortening a venetian blind is easy with just a few simple steps:

  1. Remove the plugs securing the bottom rail and undo the knots for the central cords.
  2. Remove the bottom rail and remove the desired amount of excess slats.
  3. Replace the bottom rail back in position, leaving one empty ladder space between the last slat and bottom rail.
  4. Re-thread the central cord and ladder strings through the holes in the bottom rail. Trim, leaving around 12 mm of excess length remaining. Tie knots to secure.
  5. Push the excess ladder strings back through the holes in the bottom rail, and replace the plugs to secure.

Are Venetian Blinds Safe For Kids?

Correctly installed venetian blinds are safe for any home with small children. Mandatory Australian requirements for corded internal window coverings dictate that loose cords must not form a loop 220 mm or longer, at or less than 1600 mm above floor level. Securely installing the cord cleat at the correct height is an essential step for your family's safety.

What's The Best Venetian Blind Type For Different Rooms?

When deciding on your preferred style of venetian blind, it's important to consider both the aesthetics of the blind, how it will function and the way the material will perform. Slimline venetians like those made from aluminium and PVC are best suited for recess fitting in windows without a deep frame. They're also a durable option for wet areas like kitchens, bathrooms and laundries as they'll be more resistant to steam or dampness. Likewise, faux wood venetians are a good option for these spaces as they're constructed from extruded PVC - just make sure the wider slat sizes will work with your windows in those spaces. Finally, timber venetians are a gorgeous aesthetic choice for bedrooms, living spaces and studies. The natural grainlines and rich wood tones are perfect for adding a touch of warmth to your home. Don't be tempted to install them in bathrooms as moisture-rich air can cause the slats to warp over time.
