Window dressings affect light, warmth, privacy and style. The right choice depends on the room as much as on your taste.

Questions to ask

How much light do you want to let in and keep out?
How much privacy do you need?
Is the window an unusual shape or size?
Does the room get damp or steamy?

When curtains work best

Curtains add softness and warmth, and they can make windows look taller if you hang them high and wide. Lined or thermal ones help keep a room warmer and darker.

When blinds work best

Blinds suit small windows, kitchens and bathrooms and areas where curtains might get in the way. Roller, Roman, venetian and day-and-night styles do different jobs.

Room by room

Living room: curtains for softness, or blinds for a cleaner look.
Bedroom: blackout lining or blinds for dark mornings.
Kitchen: blinds that are easy to wipe and away from the hob.
Bathroom: moisture-resistant blinds, and privacy glass where needed.

Hang them well

Mount rails or poles above and wider than the window so the curtains clear the glass when open. This lets in more light and makes the window look bigger.

Safety with children

Blind cords can be a strangulation hazard to young children. Use cordless blinds or safety devices, and keep cords out of reach.

Mistakes to avoid

Measuring the window only and not the space around it.
Hanging curtains too low.
Using fabric blinds in damp rooms.
