How to Choose the Right Curtain Liner – A Complete Guide
Curtains do more than just complete your interior style — they also block light, insulate your space, and protect your privacy. But behind every great curtain is an unsung hero: the liner. The right liner can significantly enhance the functionality of your drapery. In this guide, we break down the different types of curtain liners and how to choose the best one for your space.
🟡 Unlined
Best for: Lightweight sheers or blackout curtains that already block 100% of light
Unlined curtains are made from a single layer of fabric with no added backing. This option works well in spaces where you want to let in natural light and maintain a soft, airy look — think living rooms, sunrooms, or when pairing with 100% blackout curtain panels (like our Gary & Todd series).
Key Features:
-
Natural, lightweight fabric feel
-
No added light-blocking or insulating effect
-
Best paired with sheers or curtains that already have high blackout capabilities
⚪ White Liner

Curtain liners are designed to be used with curtains — they are not meant to be installed on their own.
-
Light-blocking percentages are estimates. Final performance depends on the curtain’s material, color, and thickness.
