Curtains are the default solution for blocking light — but they’re not always the best one.
Maybe you:
- Don’t like the bulky look
- Rent and can’t install curtain rods
- Still get light leaking around the edges
- Want a cleaner, more modern solution
The good news? You don’t need curtains to create a dark room.
Here’s how to block light from windows effectively — and why most DIY fixes don’t work long-term.
Why Light Control Matters More Than You Think
Light entering your home affects more than just brightness.
Too much light can:
- Disrupt sleep
- Overheat rooms
- Cause screen glare
- Reduce privacy
- Trigger early wakeups in kids
Windows are the biggest source of unwanted light in a home. Even “dim” light can signal to your brain that it’s time to be awake.
That’s why controlling window light makes such a noticeable difference to comfort and sleep quality.
Why Curtains Often Don’t Solve the Problem
Many people assume thick curtains will make a room dark. But even “blackout curtains” have a big flaw:
Light leaks around the edges.
Curtains hang away from the wall, which creates gaps:
- Above the curtain rail
- Along the sides
- Underneath the curtain
Sunlight pours through these gaps, especially early in the morning.
That’s why rooms with curtains often still feel bright at sunrise.
The Biggest Sources of Light Leaks
If your room never gets truly dark, these are the usual culprits:
1️⃣ Side gaps
Sunlight sneaks in between curtains and walls.
2️⃣ Top gaps
Light shines above curtain rods.
3️⃣ Thin fabric
Many “blackout” curtains are not fully light-blocking.
4️⃣ Window shape
Large or wide windows are hard to cover fully with fabric.
To block light properly, the solution needs to sit close to the window and cover the entire frame.
DIY Ways to Block Light (And Their Downsides)
People try all sorts of temporary fixes:
Tinfoil or cardboard
✔ Blocks light
✖ Looks messy
✖ Hard to remove
✖ Not practical long-term
Towels or blankets taped to windows
✔ Cheap
✖ Falls down
✖ Leaves residue
✖ Doesn’t seal edges well
Window film
✔ Reduces glare
✖ Doesn’t create darkness
✖ Still lets light through
These hacks work short-term but quickly become frustrating.
The Modern Alternative to Curtains
More homeowners and renters are switching to blackout blinds instead of curtains.
Why?
Because they’re designed specifically to:
- Sit close to the glass
- Cover the entire window area
- Minimise light gaps
- Look clean and minimal
This creates a darker room with less bulk and clutter.
How Blackout Blinds Block Light More Effectively
Blackout blinds work differently from curtains.
They use dense, layered fabric that stops light passing through the material. When fitted properly, they can create near-total darkness.
Key advantages:
- Reduced edge gaps
- Full window coverage
- Better light control
- Cleaner aesthetic
They’re especially popular for bedrooms, nurseries and media rooms where darkness matters most.
Perfect for Renters and Minimalist Homes
Curtains often require:
- Drilling
- Curtain rails
- Wall anchors
This isn’t ideal if you rent or want a damage-free setup.
Blackout blinds offer a simpler solution that works in:
- Rentals
- Apartments
- Modern homes
- Minimalist interiors
You get the function of curtains without the installation hassle.
Extra Benefit: Blocking Heat and Glare
Blocking light has another major benefit — temperature control.
Sunlight entering through windows turns into trapped heat. This is why rooms with big windows get so hot during the day.
By blocking sunlight before it enters the room, blackout blinds help:
- Keep rooms cooler in summer
- Reduce glare on screens
- Improve comfort during the day
It’s a simple upgrade that improves both sleep and energy efficiency.

Modern blackout solutions provide:
- Better darkness
