How Wide Should Curtains Be?
For most windows, curtains should be 1.5 to 2 times the width of the window. This extra width creates natural folds and gives the curtains a fuller, more elegant appearance.
- Use 1.5 times width for a cleaner, lighter look
- Use 2 times width for a fuller and more luxurious look
- Wider curtains can also improve privacy and light control
Example: If your window is 150 cm wide, choose a total curtain width of around 225–300 cm.
How Long Should Curtains Be?
Curtain length changes the overall feeling of a room. The right length can make your space look taller, softer, and more refined.
| Curtain Length Style | Description | Best For |
|---|---|---|
| Sill Length | Ends at the window sill | Kitchens, small windows, practical spaces |
| Floor Length | Touches or almost touches the floor | Bedrooms, living rooms, modern interiors |
| Puddle Length | Extends slightly onto the floor | Luxury styling, formal rooms |
For most homes, floor-length curtains are the best choice because they create a clean, balanced, and elegant finish.
