Measuring for Blockout Roller Blinds: A DIY Guide from inDesign Blinds

Getting It Right from the Start

Planning to installblockout roller blinds in your home? Ace! But before you even think about browsing through fabrics and colours, you’ve gotta nail themeasurement process. Nothing’s more frustrating than ordering blinds only to find they’re the wrong size. This guide, brought to you by inDesign Blinds, will walk you through exactly how tomeasure your windows like a pro, ensuring a perfect fit and hassle-free installation.

We’ll cover everything from understanding the difference between inside recess and face fit measurements to providing helpful tips and tricks along the way. So, grab your measuring tape, notepad and pen, and let’s get started!

Understanding Inside Recess vs. Face Fit

Before diving into the nitty-gritty of measuring, it’s crucial to understand the two primary waysroller blinds are installed: inside recess and face fit.

Inside Recess

Aninside recess fit means the blind sits *within* the window frame. This creates a clean, streamlined look and often maximises blockout capabilities. It’s a popular choice for many Australian homes.

Pros:

  • Cleaner appearance
  • Potentially better light blockout
  • Blends seamlessly with the window frame

Cons:

  • Requires very accurate measurements
  • May leave small gaps on either side (unless you order specific side channels)
  • Can be tricky to install in windows that aren’t perfectly square

Face Fit

Aface fit, on the other hand, means the blind is mounted *outside* the window frame, on the wall or architrave. This is a good option if your window frame is shallow, uneven, or you want to completely block out all light.

Pros:

  • Easier to install, especially on tricky windows
  • Greater flexibility in terms of size and placement
  • Excellent for complete light blockout (when overlapping the window frame significantly)

Cons:

  • Less streamlined appearance
  • Blinds are more exposed
  • May require more wall space around the window

Tools You’ll Need

Before you startmeasuring for your blockout roller blinds, make sure you have the following tools handy:

  • Metal measuring tape: A steel measuring tape is more accurate than a cloth one.
  • Pen and notepad: To record your measurements.
  • Spirit level: To ensure your window frame is level (important for inside recess fits).
  • A friend: Especially helpful for measuring larger windows.

How to Measure for Inside Recess Blockout Roller Blinds

Alright, let’s get down to business! This section focuses onmeasuring for inside recess blinds.

Width Measurement

Follow these steps foraccurate width measurements:

  1. Measure the width at thetop,middle, andbottom of the window recess.
  2. Record all three measurements. It’s not uncommon for windows to be slightly different widths at different points.
  3. Use the *smallest* measurement. This is crucial! Yourblind manufacturer will usually make a small deduction from this measurement (usually around 10mm-15mm) to ensure the blind operates smoothly within the recess. Don’t make this deduction yourself – let the professionals handle it.
  4. Clearly label the measurement as “Recess Width”.

Drop (Height) Measurement

Now, let’s measure the drop (or height):

  1. Measure the height at theleft,center, andright of the window recess.
  2. Record all three measurements. Again, windows aren’t always perfectly square!
  3. Use the *smallest* measurement. This ensures the blind will fully retract into the recess without hitting the sill.
  4. Clearly label the measurement as “Recess Drop”.

Important Considerations for Inside Recess Measurements

  • Check for obstructions: Are there any tiles, handles, or other obstructions that might prevent the blind from sitting flush within the recess? If so, you’ll need to account for these in your measurements or consider a face fit instead.
  • Window frame depth: Ensure your window frame is deep enough to accommodate the blind’s brackets and operating mechanism. A deeper frame is generally better for inside recess fits, allowing for a more streamlined look.
  • Squareness: Use a spirit level to check if your window frame is square. If it’s significantly out of square, an inside recess fit may not be the best option, or you may need to consult with a professional installer.

How to Measure for Face Fit (Outside Recess) Blockout Roller Blinds

If you’ve decided on aface fit installation, the measuring process is a little different.

Width Measurement

Follow these steps foraccurate width measurements for face fit blinds:

  1. Decide how much you want the blind to overlap the window frame on each side. A good rule of thumb is to add at least 50mm to 100mm on each side for optimal light blockout.
  2. Measure the width of the window frame, including the desired overlap.
  3. Record this measurement. This is the *finished width* you’ll need to provide to your blind manufacturer.
  4. Clearly label the measurement as “Face Fit Width”.

Drop (Height) Measurement

To measure the drop for a face fit:

  1. Decide how high above the window frame you want to mount the blind. This will depend on your desired level of light blockout and the aesthetics you’re aiming for.
  2. Measure from the desired mounting point to the bottom of the window frame, including any desired overlap below.
  3. Record this measurement. This is the *finished drop* you’ll need to provide to your blind manufacturer.
  4. Clearly label the measurement as “Face Fit Drop”.

Important Considerations for Face Fit Measurements

  • Mounting Surface: Ensure the wall or architrave you’ll be mounting the blind to is solid and capable of supporting its weight.
  • Obstructions: Double-check for any obstructions, such as light switches or power outlets, that might interfere with the blind’s operation.
  • Balance: Consider the overall balance and proportions of the blind in relation to the window and surrounding wall space.

Understanding Manufacturer Deductions

As mentioned earlier, mostblind manufacturers, including inDesign Blinds, will make a small deduction from your recess width measurement to ensure the blind fits and operates smoothly. This deduction typically ranges from 10mm to 15mm, but it’s always best to confirm the exact amount with your chosen supplier.

Don’t make this deduction yourself! It’s far better to provide the raw measurements and let the professionals take care of the rest. Trying to second-guess the deduction can often lead to mistakes.

Common Measurement Mistakes to Avoid

Here are a few common pitfalls to watch out for whenmeasuring for roller blinds:

  • Using a cloth measuring tape: Stick to a steel measuring tape for accurate results.
  • Rounding measurements: Always measure to the nearest millimetre.
  • Measuring only at one point: Remember to measure the width and drop at multiple points and use the smallest measurement for recess fits.
  • Assuming windows are perfectly square: They rarely are!
  • Forgetting about obstructions: Account for any tiles, handles, or other obstructions.
  • Making deductions yourself: Let the blind manufacturer handle any necessary deductions.
  • Rushing the process: Take your time and double-check your measurements before placing your order.

Choosing the Right Fabric for Blockout Roller Blinds

Once you’ve got your measurements sorted, it’s time to think aboutchoosing the right fabric for yourblockout roller blinds. There are a few key factors to consider:

Light Blockout Performance

Obviously, the primary purpose ofblockout blinds is to block out light. Look for fabrics that are specifically labelled as “blockout” and have a high opacity rating. Some fabrics are better at blocking out light than others, so it’s worth doing some research.

Colour and Style

Blockout roller blinds come in a wide range of colours and styles. Choose a fabric that complements your existing décor and personal taste. Darker colours generally provide better light blockout than lighter colours.

Durability and Maintenance

Consider the durability and ease of maintenance of the fabric. Look for fabrics that are resistant to fading, staining, and tearing. Easy-to-clean fabrics are also a plus, especially in high-traffic areas.

Thermal Properties

Someblockout fabrics also offer thermal insulation properties, which can help keep your home cooler in summer and warmer in winter. This can save you money on energy bills and make your home more comfortable year-round. Check out the *Energy saving properties* of the Blockout fabric carefully before buying.

FAQs: Measuring for Blockout Roller Blinds in Australia

  • What's the difference between inside recess and face fit blinds?

    Inside recess blinds fit *within* your window frame, giving a neat, streamlined look. Face fit blinds are mounted *outside* the frame, on the wall or architrave. Face fit is better if your window isn't square, or you want maximum blockout.
  • What tools do I need to measure for blockout roller blinds?

    You'll need a metal measuring tape, pen and paper for notes, a spirit level (especially for inside recess fits), and it can be handy to have a mate to help, particularly for larger windows.
  • How do I measure the width for inside recess blockout blinds?

    Measure the width at the top, middle, and bottom of the recess. Use the *smallest* of these measurements. The blind mob will make a small deduction (usually 10-15mm) to ensure a smooth fit. Don't deduct it yourself!
  • How do I measure the drop (height) for inside recess blinds?

    Measure the height at the left, centre, and right of the recess. Use the *smallest* measurement. Again, this ensures the blind retracts fully without hitting the sill. Mark it clearly as "Recess Drop".
  • How do I measure the width for face fit (outside recess) blinds?

    Decide how much you want the blind to overlap the window frame on each side (50-100mm is a good starting point for better light blockout). Measure the window frame width plus the desired overlap. That's your finished width.
  • How do I measure the drop (height) for face fit blinds?

    Decide how high above the window frame you want to mount the blind. Measure from the mounting point to the bottom of where you want the blind to finish, including any desired overlap below the window. That's your finished drop.
  • Should I make deductions when measuring for inside recess blinds?

    Nah, mate, don't do it! Provide the raw measurements to the blind manufacturer, and they'll take care of any necessary deductions to ensure a perfect fit.
  • What are some common measuring mistakes to avoid?

    Using a cloth tape, only measuring at one point, assuming windows are perfectly square, forgetting about obstructions, making deductions yourself, and rushing the job! Take your time, double-check, and use a metal tape.
  • What type of fabric should I look for in blockout roller blinds?

    Look for fabrics specifically labelled as "blockout" with a high opacity. Darker colours generally block more light. Also, consider durability, ease of cleaning, and any insulating properties the fabric might have.
  • Is it worth getting a professional to measure and install my blinds?

    If you're unsure about any part of the measuring or installation process, it's definitely worth considering. A professional can ensure accurate measurements and a hassle-free installation, saving you time and potential headaches down the track and ensure correct professional blind installation.
