Sheer vs Blockout Curtains: How to Choose

It's one of the most common questions we get — and the answer is almost always: both. But if you're deciding between sheer and blockout curtains for a specific room, or trying to understand what each one actually does, this guide will help you choose with confidence.

What Sheer Curtains Do

Sheer curtains are made from a loosely woven, lightweight fabric that allows light to pass through while softening it. They don't block your view or darken a room — they transform the quality of the light that enters it.

In practice, this means:

• Rooms feel brighter and airier
• Harsh afternoon sun becomes warm, diffused light
• You maintain a sense of connection to the outside
• During the day, they provide privacy without darkness

Sheer curtains work in almost any room, but they're especially effective in living rooms, dining spaces, and home offices — anywhere you want natural light but not the full glare of it.

What Blockout Curtains Do

Blockout curtains use a tightly woven or coated fabric that prevents light from passing through. When they're closed, the room is dark. Full stop.

In practice, this means:

• Bedrooms stay dark in the early morning
• Nurseries and children's rooms support sleep at any time of day
• Media rooms maintain picture quality without light washing out the screen
• You have complete control over when light enters and when it doesn't

The Case for Both: Double Track Curtains

The most considered solution for most rooms — especially bedrooms — is a double track system that pairs sheer and blockout curtains on the same window.

During the day, draw the sheers. The room is bright, light is softened, and you have daytime privacy without the curtains being closed. In the evening or when you want to sleep, close the blockout. The room is dark, the sheers sit behind them, and both look intentional when open.

It's the approach most interior designers would recommend for primary bedrooms, and it's one of the options we offer across our full range.

Quick Reference Guide

Choose sheer curtains if: You want to filter and soften natural light, maintain a connection to the outside, and create an airy, considered feel in a living or dining space.

Choose blockout curtains if: You need complete light control for sleep, media viewing, or privacy at any hour.

Choose both (double track) if: You want complete flexibility — light and openness during the day, full darkness when you need it. The best investment for bedrooms.
