Blackout Curtains vs Room Darkening Curtains: What's the Difference?

TL;DR: Blackout curtains and room darkening curtains are not the same. Room darkening curtains reduce the amount of light entering a room, while blackout curtains are designed to block significantly more light. If your goal is better sleep, a nursery, a home theater, or a hotel-style bedroom, blackout curtains are usually the better choice.

If you're shopping for new curtains, you've probably come across the terms blackout curtains and room darkening curtains.

At first glance, they sound almost identical. In reality, they serve different purposes.

Understanding the difference can help you choose the right curtains for your bedroom, nursery, living room, or home theater.

In this guide, we'll compare blackout curtains vs room darkening curtains, explain their pros and cons, and help you decide which option is best for your home.

What Are Room Darkening Curtains?

Room darkening curtains are designed to reduce the amount of natural light entering a room.

They use thicker fabrics than standard decorative curtains but are not intended to block all incoming light.

Instead, they soften daylight and make a room noticeably dimmer.

They're commonly used in:

  • Living rooms
  • Dining rooms
  • Home offices
  • Guest rooms
  • Media rooms

Many people choose room darkening curtains when they want privacy and glare reduction without making the room completely dark.

What Are Blackout Curtains?

Blackout curtains are specifically designed to block as much outside light as possible.

They typically use tightly woven fabrics, specialized linings, or multiple fabric layers that significantly reduce light passing through the curtain itself.

When properly installed, blackout curtains create a much darker room than room darkening curtains.

They're especially popular in:

  • Bedrooms
  • Nurseries
  • Children's rooms
  • Hotels
  • Home theaters
  • Apartments
  • Shift worker bedrooms

Blackout Curtains vs Room Darkening Curtains

Here's a side-by-side comparison.

Feature Blackout Curtains Room Darkening Curtains
Light Blocking Excellent Moderate
Sleep Quality Excellent Good
Privacy Excellent Very Good
TV & Screen Glare Excellent Good
Nursery Use Excellent Fair
Home Theater Excellent Good
Decorative Use Excellent Excellent
Energy Efficiency Often Better Good

Which Blocks More Light?

Blackout curtains.

That's the biggest difference.

Room darkening curtains reduce sunlight, but you'll usually still notice daylight filtering through the fabric.

Blackout curtains are manufactured specifically to block significantly more light.

Keep in mind that no curtain can completely eliminate light if gaps exist around the edges of the window.

That's why proper sizing is just as important as the fabric itself.

Which Is Better for Sleeping?

If your goal is improving sleep, blackout curtains are generally the better option.

Darkness helps support your body's natural circadian rhythm and melatonin production.

Many people choose blackout curtains because they help reduce:

  • Early morning sunlight
  • Streetlights
  • Security lights
  • Car headlights
  • Light pollution from neighboring buildings

Which Is Better for Nurseries?

Most parents choose blackout curtains.

Babies often nap during daylight hours, and reducing outside light can create a more consistent sleep environment.

A darker nursery may also help reduce visual distractions during naps.

Which Is Better for Home Theaters?

Blackout curtains are usually preferred.

They reduce reflections on televisions and projector screens, helping create a more enjoyable viewing experience.

Which Looks Better?

Both options are available in a wide range of colors, fabrics, and styles.

Modern blackout curtains no longer have the heavy, bulky appearance they once did.

Today, they're available in:

  • Linen-look fabrics
  • Textured weaves
  • Cotton blends
  • Velvet
  • Neutral colors
  • Contemporary designs
  • Many homeowners choose blackout curtains without sacrificing aesthetics.

Do Blackout Curtains Make a Room Too Dark?

Only when they're closed.

During the day, you can simply open the curtains to let natural light enter the room.

When closed, blackout curtains create a darker environment that's ideal for sleeping, movie nights, or reducing glare.

Do Room Darkening Curtains Save Energy?

Both blackout curtains and room darkening curtains can help reduce heat transfer through windows.

Because blackout curtains often use thicker materials, they may provide slightly better insulation depending on the construction and installation.

Are Custom Blackout Curtains Better?

Many homeowners choose custom blackout curtains because they're designed specifically for each window.

Compared to standard ready-made curtains, custom curtains often provide:

  • Better window coverage
  • Reduced light gaps
  • Cleaner appearance
  • More luxurious drape
  • Better compatibility with oversized windows

For example, Evernights specializes exclusively in custom blackout curtains. Their made-to-measure approach allows each curtain to be tailored to the customer's exact window dimensions, helping reduce light leakage while creating a premium, hotel-inspired appearance.

When Should You Choose Room Darkening Curtains?

Room darkening curtains may be the better choice if you:

  • Want softer natural light
  • Primarily need privacy
  • Want to reduce glare
  • Don't require complete darkness
  • Are decorating a living room or dining room

When Should You Choose Blackout Curtains?

Blackout curtains are often the better option if you:

  • Want better sleep
  • Wake up from morning sunlight
  • Have a nursery
  • Work night shifts
  • Want a home theater
  • Live near streetlights
  • Want maximum privacy
  • Want a luxury hotel bedroom feel
