Should Curtains Touch the Floor? Interior Designers' Golden Rule for Window Treatments, Explained

The answer to 'should curtains touch the floor?' is something that's debated by designers to a certain degree. That's because hanging them depends on a few factors; be it the length of the window, the material of the drapes and the look you want to create. 

If using a textile that has a little structure, the curtain stack can become a little distorted from touching the floor, meaning you don't get the perfect drape from your modern window treatment. So what length is ideal?

I set out to find definitive answers, and here's what designers had to say.

Can I leave a gap between the curtains and the floor?

Looking for the best curtain ideas and styles to help you pick the best drapes for your room? You want to be careful about what type of look it'll give to the overall space. There's a fine line between curtains touching the floor and a gap that makes your floor-length curtains look like you've ordered them too short – the peddle pushers of the window treatment world. 

'Our golden rule is that we usually keep them 1/4" off the floor,' says interior designer Lisa Staton. 'This keeps them long and generous, but not collecting dust.' 

'I equate curtains not touching the floor to a bad haircut when your bangs are cut too short – it never looks right,' interior designer Becky Shea. If you're ordering (or hemming) curtains yourself, there's a small margin for error when measuring for curtains. However, if they arrive and they're a little off from what you were hoping, there's always the option to hang your curtain rod a little higher. 

If you're working with professional, interior designers Berkeley Minkhorst and Kelley Lentini, founders and principals of House of Nomad have the words to describe what you want eloquently. 'Our general rule is that curtains should 'kiss' the floor,' they explain. 'This look always feels polished, classic, and modern which complements our aesthetic.' 

Are puddling curtains out of style? 

Longer, puddling curtains are more the domain of traditional, period homes looking for a flourish. 'If clients ask, we do the 'puddle' but it's not our normal choice,' says Lisa.  

If you do decide for your living room curtains to touch the floor, they really should only just touch the floor – this makes them the perfect length for blocking out light, drafts and offering that luxurious look, without being too impractical. More significant puddles aren't particularly on trend right now but matched with a contemporary textile, a slight puddle still looks fresh. 

'In the design world, we refer to the moment the drapery touches the floor as the 'break' and the material that's beyond that sitting on the floor as the 'puddle',' says Becky. 'We never recommend going beyond 1/2" for the puddle and in some cases just skimming the floor is enough.'

Does your choice of textile make a difference?

Along with knowing how to hang curtains, when you're dealing with such fine margins of measurements, it pays to know how different fabrics react as well. 'Linen, for example will always move and shrink, growing with the seasons,' says Lisa. 

When using natural fibers like cotton, silk or wool, they're also prone to stretch once hung which may change your gap over time, especially with heavier materials. In this instance, a broken puddle on the floor will help relieve some of the weight on your curtains, too. 

Where should curtains hit the ground?

When installing the curtain, you want the fabric to just lightly touch the floor or hover 1/2 inch above. This way, they look more stylish, give the room height and make the space seem more luxurious.

Can you hang curtains too high?

Ideally, the best height to hang curtains is just below the crown (the area where the walls and ceiling meet) – while still maintaining a relationship with the window. Of course, in the case of a double or triple-height room, don't take the drapery to the crown.
