Top Mistakes to Avoid When Buying Double Roller Blinds

Get the look and function right the first time

Double roller blinds are one of the smartest, most flexible window coverings you can choose — combining day and night privacy in one tidy system. But to get the most out of them, it’s important to avoid a few common slip-ups that can affect how they look, operate, and perform over time.

Here are the top mistakes we see — and how you can avoid them.

1. Not Measuring Properly

The most common mistake? Incorrect measurements. Double roller blinds need to be measured precisely to fit well, especially when dealing with two layers of fabric.

• Use a steel tape measure (not a cloth one) Or a laser metre
• Measure each window individually — even if they look the same
• Follow our Measuring Guide to get it right the first time

2. Choosing the Wrong Fit (Face vs Recess)

Some buyers mix up where they want the blinds installed: inside the window frame (recess fit) or on the wall above it (face fit).

Recess fit offers a sleek, built-in look — but comes with small light gaps. Face fit provides better blockout and full coverage.

Decide based on your priorities:look vs light block

3. Selecting Incompatible Fabrics

Your day and night blinds should work as a team. If the sunscreen fabric is too dark or the blockout fabric is too light, you may not get the look or function you want.

• ⁠Pair your fabrics thoughtfully — for contrast or cohesion
• ⁠Order ⁠free fabric samples to test them side-by-side

4. Forgetting About Chain Placement

Double rollers have two chains — one for each blind. If you don’t consider which side you want the chains on, you might block access or interfere with furniture.

• Think about what’s nearby: window handles, cabinetry, or beds
• Choose the side that feels most intuitive for everyday use

5. Overlooking Bottom Rail Style

The bottom rail isn’t just functional — it’s a key part of your blind’s visual finish. At iSeekBlinds, you can choose between flat and curved styles (with matching colours).

• Flat = minimalist and crisp, available in black, white or silver
• Curved = softer finish, available in black only
• Compare bottom rail styles

6. Not Factoring in Light Control Needs

Some rooms need full blockout at night and glare protection during the day — others don’t. Picking the wrong day blind (sunscreen vs light filtering) can affect comfort.

• Sunscreen = daytime views + privacy
• Light filtering = more privacy + soft glow

7. Missing Out on Motorisation

Many customers assume motorised blinds are too expensive or complicated — but that’s not the case anymore.

Battery-powered motors (like Automate or RollerIQ) are simple to install and offer serious day-to-day comfort.

Mix and Match: Many customers find they rarely adjust the sunscreen blind, so they keep that manual and go motorised for the blockout. It’s a clever combo that gives you the best of both worlds—functionality and cost savings.

• Motorised blinds = no chains, no tangles, no effort
• Control with remote or smart device
• ⁠⁠Explore control options

8. Choosing a Fabric without Checking It in Your Space

A fabric may look one way on screen and another in real life. Lighting, wall colour, and furnishings can all change the way it appears.

Order free samples to check colour, texture, and light effect in your own space.

9. Not Considering Safety

Corded blinds must comply with Australian safety standards, especially in homes with kids or pets. You’ll need to install chain safety clips to prevent hazards.

• For a safer option, go motorised or use child-safe chain tensioners
• Always follow ⁠our safety guide

10. Installing Without Checking Obstructions

If there are handles, trims, tiles or other hardware near your window, you’ll want to double-check how much space your blind needs to operate smoothly.

Consider bracket projection or choose face fit to clear obstacles.

11. Not Asking for Help When You Need It

• Better to ask a question now than fix a mistake later
