Buying blinds seems simple—but many people make small mistakes that cost time, money, and comfort later on. Whether you’re a first-time buyer or updating a few rooms, here are the top 5 blind-buying mistakes to avoid (and what to do instead).
Guessing the Measurements
Eyeballing your window size or measuring once “just to get an idea”? That’s the fastest way to end up with blinds that don’t fit—or worse, don’t work at all.
What to do instead:
- Use Apollo’s easy online measuring guides
- Measure twice: width and drop, inside or outside mount
- Double-check each window individually—no two are the same
Tip: Always round to the nearest mm and keep notes for every room.
Picking the Wrong Mount Type
Choosing inside mount vs outside mount can affect light control, privacy, and how the blind looks in your space.
• Inside mount = a sleek look, fitted within the window frame
• Outside mount = better for blocking light, hiding old frames
Tip: For full blockout, go outside mount with blockout fabric.

Forgetting About Sun Direction
Not all rooms get the same sunlight. Choosing the wrong fabric for a hot, west-facing room or a dark corner space can ruin your comfort.
• Go blockout for hot, sunny windows
• Use screen or light-filtering fabric for rooms with softer light
• Try dual blinds for flexibility across day and night
Tip: Consider the room’s use (e.g., bedroom vs kitchen) when selecting fabric.
Choosing Colour Online Without Testing
Photos on a screen can look very different in person. Lighting, wall colour, and time of day all affect how blind fabrics appear.
What to do instead:
- Always order free fabric swatches from Apollo
- Test them in each room’s natural light
- Compare to walls, floors, and furniture for the best match
Tip: Stick to neutrals for flexibility or use contrast to highlight windows.
Overlooking Installation or DIY Readiness
Not all blinds are suited for all homes—or for all DIY levels. Make sure your choice suits your space, tools, and install comfort level.
• Roller and blockout blinds = perfect for DIY
• Larger windows/sliding doors = may need an extra hand
• Renters? Look for no-drill options or ask about damage-free fittings
Tip: Apollo provides detailed install instructions and support if you need help.
