How wide should a curtain box be? There is no standard answer to this question – it mainly depends on your home’s specific situation, and the right size largely depends on the number of curtain tracks you need to install.
Our aluminum alloy curved curtain box features a fixed-width design – 11 cm for single track and 16 cm for double track – making installation simple while delivering a sleek, streamlined appearance.
Starting with the 11 cm single-track curtain box
The 11 cm width is designed for a single curtain track, making it suitable for projects with one layer of curtains, such as a single fabric curtain or sheer curtain. Single tracks on the market generally range from 6–8 cm in width, so the 11 cm size is more than adequate for this application.
Moving on to the 16 cm double-track curtain box
The 16 cm width is designed for two curtain tracks, making it ideal for the common combination of sheer curtains + blackout/fabric curtains. Both tracks are housed inside the curtain box, and with a built-in quiet-glide design, the curtains operate smoothly and silently.
The curtain box also features a unified height of 11 cm, which provides effective coverage of the curtain header area in most homes, helping to block light from passing through the top of the curtains.
For curtain retailers, interior designers, contractors, and project buyers, you simply need to ensure that your window area has sufficient space for installation:
- 11 cm – Single Track
- 16 cm – Double Track
This fixed-width design makes it easier to specify the right curtain box for different curtain installation projects.
