How to Choose

• Light blockage rating: Look for '100% blackout' or 'total blackout' labels. Some blinds claim blackout but let light through edges.
• Window type and size: Standard windows suit off-the-shelf blinds; bay or arched windows need made-to-measure options like Hillarys.
• Installation method: Renting? Choose no-drill blinds (Next) or tension rods. Homeowners can use screws for a permanent fix.
• Material and insulation: Thermal or honeycomb blinds (Tredwells) help with temperature and noise, important for UK bedrooms.
• Budget versus longevity: Cheap blinds (IKEA) work but may wear faster. Invest in John Lewis or Hillarys for durability.
• Aesthetic preference: Roman blinds add style, rollers are minimalist, venetians offer light control. Pick what fits your room's vibe.
