Expert Guide
Everything You Need to Know About Vertical Blinds
-
✦
What are vertical blinds?
Vertical blinds consist of long fabric slats (louvres) that hang from a top track. They rotate to control light and privacy, and draw to one side or split centrally — making them ideal for wide windows and sliding doors.
-
✦
Are they suitable for sliding doors?
Absolutely — vertical blinds are the most popular choice for sliding doors in Australian homes. The slats draw smoothly to the side, allowing easy access without obstruction.
-
✦
What's the difference between blockout and standard?
CAS Blinds offers full blockout vertical blinds — the fabric is opaque and blocks virtually all incoming light, offering both privacy and heat control. Perfect for bedrooms and media rooms.
-
✦
How do I clean vertical blinds?
Regular dusting with a dry cloth or duster keeps them clean. For stains, gently wipe individual slats with a damp cloth. The slats can be detached from the track for more thorough cleaning if needed.
-
✦
Can I get motorised vertical blinds?
Yes. CAS Blinds offers motorised blind options for added convenience. Visit our Motorisation page for more details.
Measuring Guide
How to Measure for Vertical Blinds
Accurate measurements are the key to a perfect fit. Follow these steps before you order.
-
1
Choose Recess or Face Fit
Recess fit = blind sits inside the window frame. Face fit = blind covers the frame edge-to-edge (add 50–100mm to each side).
-
2
Measure Width
Take 3 width measurements — top, middle, and bottom. Use the smallest for a recess fit. We recommend adding 100–150mm each side for a face fit.
-
3
Measure Drop
Measure from the top of the track down to the floor (or desired length). Measure in millimetres for accuracy.
-
4
Enter Measurements Online
Enter your exact measurements when ordering. We do NOT make deductions — enter the size you want the finished blind to be.
Pro Tips Before You Order
- Always measure in millimetres — not centimetres
- Use a metal tape measure for accuracy
- Measure each window individually — they may differ
- Double-check measurements before submitting

FAQs
Frequently Asked Questions
Everything you need to know about buying vertical blinds online.
What are vertical blinds and how do they differ from roller blinds?
Vertical blinds feature individual slats that hang vertically and rotate to control light, while roller blinds use a single fabric panel that rolls up or down. Vertical blinds are especially well-suited to wide windows and sliding doors, where a roller blind would require multiple brackets and may sag over a wide span. Browse our full range of vertical blinds or roller blinds.
Are vertical blinds a good choice for large windows or sliding doors?
Yes, they're perfect for wide windows and sliding doors as they glide smoothly and provide excellent light and privacy control. The slats can draw to one side or split in the centre, so you can open the door without disturbing the rest of the blind — something a roller blind can't do.
Can vertical blinds be customised to match home interiors?
Absolutely — they're available in various colours, materials, and finishes to complement any interior style. At CAS Blinds you can choose from blockout fabrics in a range of neutral and on-trend tones to suit both contemporary and classic Australian homes.
What are the maintenance tips for keeping vertical blinds clean?
Regular dusting and occasional spot cleaning with a damp cloth keep them looking fresh and extend their lifespan. For heavier cleaning, individual slats can be unclipped from the track and wiped down. Avoid soaking the fabric as this may cause warping of the slat hooks.
How do blockout vertical blinds help reduce glare and heat?
Their thick, light-blocking material prevents harsh sunlight from entering, reducing glare and keeping rooms cooler. This also helps lower energy costs in summer by reducing the solar heat gain through large glass windows and sliding doors.
How do blackout vertical blinds help in controlling light and privacy?
Blackout vertical blinds use opaque fabric that blocks sunlight and offers complete privacy, ideal for bedrooms and living areas. Unlike standard fabric blinds, the blockout slats prevent any light from passing through the material — though small gaps at the edges and between slats are normal.
What's the difference between 89mm and 127mm slats?
89mm slats are the traditional width — they create a denser appearance with more slats visible, and work well in most standard rooms. 127mm slats are wider, giving a more modern, open look. They're especially popular for large sliding doors and contemporary homes. Shop our 89mm blockout blinds or 127mm blockout blinds.
How long does it take to receive my vertical blinds?
Production and dispatch times vary — please refer to the product page for current lead times. We ship Australia-wide. For more details, see our shipping policy.
Can I get a professional measure and quote instead of DIY?
Yes. If you'd prefer a professional to measure and quote your windows, we offer this service. Simply book a professional measure & quote and our team will visit your Sydney home or office at a time that suits you.
Do you offer wholesale or trade accounts?
Yes — CAS Blinds offers trade accounts for builders, interior designers, and property managers. Visit our wholesale & trade accounts page to apply online.
