If you live in a Sydney apartment, you've probably noticed an uncomfortable truth: those stunning floor-to-ceiling windows and sliding doors that sold you on the place are also your biggest decorating challenge. Too much sun streaming in, not enough privacy, and energy bills creeping up with every season.

Vertical blinds might be the answer you've been overlooking.

As one of the most popular window coverings in Sydney apartments, vertical blinds offer an unbeatable combination of affordable pricing, flexible light control, and straightforward installation. But with so many options available — different materials, sizes, and retailers — how do you make the right choice without wasting money on costly mistakes?

This comprehensive guide covers everything you need to know, from choosing the right material to mastering the three-point measuring technique that prevents the measurement errors affecting 35% of DIY buyers.

Why Vertical Blinds Are the Top Choice for Apartment Living

In Sydney, apartments make up over 65% of the housing market. With median unit rents hitting $721 per week as of October 2025 (source: Domain Rental Report), every dollar of your fit-out budget matters. Here's why vertical blinds consistently outperform other window covering options for apartment dwellers:

Perfect fit for large windows and sliding doors. Apartments typically feature wide sliding doors and floor-to-ceiling windows exceeding 2 metres in width. Unlike curtains that bunch up or roller blinds that struggle with extra-wide openings, vertical blinds are specifically engineered for horizontal movement across large spans.

Precision light control. Simply rotate the vane angle to transition seamlessly from full blackout to soft, filtered daylight — far more nuanced than the all-or-nothing approach of roller blinds. For apartments facing west or north where Sydney's afternoon sun hits hardest, this level of control is essential.

Budget-friendly pricing. Individual windows start from just $59, meaning you can outfit an entire two-bedroom apartment with 4-5 windows for $236-$1,000 depending on material choice — substantially less than custom curtains or plantation shutters.

Straightforward DIY installation. Most vertical blind systems use standardised mounting brackets and can be installed with basic tools in 2-3 hours per window. For step-by-step instructions, see our DIY vertical blinds installation guide.

Material Comparison: PVC, Fabric, or Aluminium?

Choosing the wrong material is one of the most common — and most expensive — mistakes new buyers make. Each material serves different needs, and the right choice depends on your space, budget, and lifestyle.

| Feature | PVC Vertical Blinds | Fabric Vertical Blinds | Aluminium Vertical Blinds |

|---------|---------------------|----------------------|--------------------------|

| Price per window | $59 – $200 | $200 – $350 | $250 – $400 |

| Durability | ★★★★★ Excellent | ★★★ Good | ★★★★ Very Good |

| Light blocking | ★★★★ Strong | ★★★ Moderate | ★★★★★ Complete |

| Cleaning | Wipe clean | Detach & wash/dry clean | Wipe clean |

| Aesthetic | Functional basics | Soft, premium look | Sleek, modern |

| Moisture resistance | ★★★★★ | ★★ | ★★★★★ |

| Best for | Kitchen, bathroom, bedroom | Living room, bedroom | Living area, home office |

How to choose:

• Budget-conscious or renting? PVC is your best bet. CAS Blinds' blockout vertical blinds in 89mm slats start from just $59, offering excellent value with full light-blocking capability. Available in colours including Cloud, Driftwood, Ash, and Sage.

• Want a premium look for your owner-occupied apartment? Fabric vanes deliver a softer, more sophisticated appearance that elevates living rooms and master bedrooms.

• Prefer contemporary minimalism? Aluminium vanes provide clean lines and a modern aesthetic that complements architecturally designed apartments.

The Three-Point Measuring Method: Avoiding the 35% Error Rate

Here's a statistic that might surprise you: approximately 35% of DIY blind buyers end up with products that don't fit properly due to measurement errors. That means wasted money, return shipping costs, and weeks of delay. The three-point measuring method eliminates this risk entirely.

Step 1: Choose Your Mount Type

| Mount Type | Inside Mount (Recess Fit) | Outside Mount (Face Fit) |

|-----------|--------------------------|-------------------------|

| Position | Inside the window frame | On the wall above/around the frame |

| Appearance | Clean, flush finish | More complete coverage |

| Requires | Frame depth ≥ 70mm | Any frame depth |

| Measurement | Internal frame dimensions | External frame + overlap allowance |

Step 2: Measure Three Points

For width: Measure across the top, middle, and bottom of the window frame. Record the smallest measurement.

For height: Measure down the left side, centre, and right side of the frame. Record the smallest measurement.

> 🔑 The golden rule: Always use the smallest measurement. Blinds slightly too narrow will still function; blinds too wide simply won't fit.

Step 3: Check the Diagonals

Measure both diagonal distances across the window frame. If the difference exceeds 10mm, your frame isn't perfectly square. In this case, opt for an outside mount with 50-75mm overlap on each side.

Common Measurement Mistakes to Avoid:

| Mistake | Consequence | Prevention |

|---------|-------------|------------|

| Measuring at one point only | Blinds too large or too small | Always measure three points, use smallest |

| Confusing inside/outside mount dimensions | Completely wrong fit | Confirm mount type before ordering |

| Forgetting to check for obstructions | Blinds blocked by handles or locks | Inspect entire frame perimeter |

| Using a fabric tape measure | Inaccurate readings | Use a steel tape measure, measure to the millimetre |

Budget Planning: From Single Window to Whole Apartment

Smart budget planning is the difference between a successful apartment fit-out and a financial headache. Here's what to expect based on apartment size:

| Apartment Type | Windows | PVC Budget | Fabric Budget | Mixed Approach |

|---------------|---------|------------|--------------|----------------|

| Studio / 1-bed | 2-3 | $118 – $600 | $400 – $1,050 | $250 – $750 |

| 2-bedroom | 4-5 | $236 – $1,000 | $800 – $1,750 | $500 – $1,200 |

| 3-bedroom | 5-7 | $295 – $1,400 | $1,000 – $2,450 | $650 – $1,800 |

Prices based on standard apartment window sizes. Custom or oversized windows may cost more.

The Smart Staging Strategy

Don't try to outfit every window at once. Instead, prioritise in phases:

1. Phase 1: Master bedroom and living room (highest privacy need and daily use)

2. Phase 2: Spare bedrooms and study

3. Phase 3: Kitchen and bathroom (consider roller blinds as a cost-effective alternative)

This approach spreads out your spending and allows you to adjust your choices based on your experience with the first batch.

Online Shopping vs In-Store: Which Is Right for You?

| Factor | Online Purchase | Showroom Visit |

|--------|----------------|----------------|

| Pricing | Generally lower (no shopfront costs) | Slightly higher, includes consultation |

| Decision time | 1-3 days to research and compare | Same-day decisions possible |

| Material experience | Can't feel the fabric | Touch and compare materials in person |

| Custom flexibility | Wide range of standard configurations | More flexible for non-standard sizes |

| Return risk | Higher if measurements are wrong | Lower with professional measuring |

| Best for | Experienced buyers with standard windows | First-time buyers or unusual window shapes |

The best of both worlds: Visit the showroom first to see and feel materials, then measure at home and order online for factory-direct pricing. CAS Blinds operates both a physical showroom in Homebush West and a comprehensive online store with full DIY custom options, giving you seamless flexibility between the two channels.

You can also order free samples online to compare colours and materials at home before committing to a full order.

DIY Installation vs Professional Fitting: Save Money or Save Time?

This is the question every apartment owner wrestles with. Let's look at the numbers:

| Factor | DIY Installation | Professional Installation |

|--------|-----------------|--------------------------|

| Cost per window | $0 (your labour) | $100 – $300 |

| Savings on 5 windows | $500 – $1,500 | — |

| Time required | 2-4 hours per window | 30 minutes per window |

| Tools needed | Drill, spirit level, tape measure | None — installer brings everything |

| Failure rate (standard blinds) | ~10% | <1% |

| Failure rate (motorised) | ~40% | <2% |

| Warranty | Product only | Product + installation guarantee |

DIY makes sense when:

• You have basic experience with a power drill

• Your windows are standard sizes and shapes

• You're installing manual (non-motorised) vertical blinds

• You're comfortable following video installation guides

Professional installation is worth it when:

• You're in a high-rise apartment with limited external access

• You're fitting motorised blinds (the 40% DIY failure rate speaks for itself)

• Your windows are unusually shaped or positioned

• You need multiple windows done quickly and correctly

Renter-Friendly Solutions: Take Your Blinds When You Move

With Sydney's vacancy rate at just 1.3% as of October 2025, renters need solutions that work without damaging walls or violating lease agreements. Here are three proven approaches:

Tension rod mounting:

• Spring-loaded rods press against the inside of the window frame

• Zero drilling required

• Completely removable when you move

• Works for window widths between 60-150cm

Ready-made standard sizes:

• No custom ordering needed — buy off the shelf and install immediately

• Standard sizes fit approximately 90% of apartment windows

• Lowest price point, ideal for short-term leases

Removable adhesive mounting:

• Uses specialised mounting brackets with 3M Command strips or similar

• Weight limitations apply — best for lightweight blinds

• Leaves no marks when removed properly

> 💡 Renter's tip: Photograph wall conditions before installation and keep all original packaging and hardware. If you choose screw-mounted installation, fill holes with white wall filler before moving out — most landlords won't even notice.

Frequently Asked Questions

Q: Are vertical blinds or roller blinds better for apartments?

A: Vertical blinds are superior for windows wider than 1.5 metres, particularly sliding doors and floor-to-ceiling windows, and they're typically more affordable per square metre of coverage. Roller blinds work better for standard-sized bedroom and bathroom windows. Many apartment owners use a "mixed approach" — vertical blinds in the living area, roller blinds in bedrooms and bathrooms — to optimise both functionality and budget.

Q: What's the difference between 89mm and 127mm vane widths?

A: The 89mm vanes are more compact and refined, ideal for windows up to 1.5 metres wide where they create a neater visual effect. The 127mm vanes cover more area per vane, making them better suited for windows over 2 metres wide where they're easier to operate and require less track hardware. CAS Blinds offers blockout vertical blinds in both sizes from $59, so you can choose based on your window dimensions rather than budget constraints.

Q: Do vertical blinds block UV rays?

A: Blockout vertical blinds block up to 99% of UV radiation and virtually all external light. For west-facing or north-facing apartments that cop Sydney's strongest afternoon sun, blockout vanes not only protect furniture from fading but also reduce summer cooling costs significantly. According to industry data, effective window coverings can reduce cooling expenses by up to 30%.

Q: How long does delivery take for online orders?

A: Ready-made standard sizes typically arrive within 3-5 business days to Sydney metro addresses. Made-to-measure blinds require 7-14 business days including production time. CAS Blinds offers local Sydney delivery, with some products available for pickup from their Homebush West showroom.

Q: What if I'm not sure which material to choose?

A: Order free samples first. CAS Blinds provides complimentary material samples shipped to your door, so you can compare textures, colours, and light-filtering properties at home before placing your full order. It's the smartest way to avoid buyer's remorse.

Making Your Decision

Choosing vertical blinds isn't just about picking a window covering — it's about investing in comfort, privacy, and style for your apartment living. Whether you're a first-time renter setting up your new place or a long-term owner looking to upgrade, the formula for success is straightforward:

4. Define your priorities: Is it blackout capability, privacy, aesthetics, or all three?

5. Measure precisely: Use the three-point method to eliminate fitting errors

6. Budget strategically: Phase your purchases, starting with the rooms you use most

7. Buy smart: Factory-direct pricing eliminates the middleman markup without compromising quality

CAS Blinds, Sydney's factory-direct window covering specialist, offers blockout vertical blinds from just $59 in both 89mm and 127mm configurations, with free professional measuring across Greater Sydney and the option to DIY or have experts handle the installation.
