Frequently Asked Questions

How wide should my curtains be?

You want to make sure that when your curtains are open they don’t block your windows so that you can maximise natural light into your room. Each curtain heading type stacks back differently, as each heading uses different amounts of fabric. To make sure your curtains don’t block your window when open, you need to add a few centimetres to the width of your window measurement -


Eyelet / Wave - Add 30cm per 1m of window frame


Pencil / Double Pleat / Triple Pleat - Add 40cm per 1m of window frame


Cartridge / Goblet - Add 60cm per 1m of window frame

Should my curtains touch the floor?

It’s up to you! Having short or long curtains is a style preference. If you opt for long curtains, we have three different types of pooling (sometimes called puddling) which determines the amount of fabric that gathers on the floor. See inspiration and more information here.

Do curtains have seams or joins?

The possible width of a fabric comes from the width of the roll. If your windows are wider than the fabric width then it is necessary to have a vertical join to cover the entire window. The way curtains have pleats and hang means seams are usually less noticeable and hidden in folds of the fabric. In most cases, curtains are a better option for wider windows.
