How to Choose

• Light blocking level: Check if curtains are labelled 'blackout' (100% block) or 'room darkening' (partial block). For total darkness, go for blackout.
• Size and fit: Measure your window width and drop carefully. Curtains should be wider than the window to prevent light leakage at the sides.
• Fabric and care: Consider whether you need machine washable options (Dunelm, Silentnight) or can manage dry-clean only (John Lewis).
• Installation type: Eyelet curtains are easiest for DIY; pole or track systems may need extra brackets. Bespoke options include professional fitting.
• Budget: Prices range from £18 to £200+. Decide how much you're willing to spend for quality and longevity.
• Additional features: Thermal insulation helps with energy bills, and noise reduction is a bonus for street-facing rooms.
