If the choice is for blinds, we advise to ensure you measure the window width and drop, while adding at least 6.5cm extra on each side of the window.
The more you can have added to the sides, the less light bleed into the room. This is important during those long summer days when the sunrise can disrupt sleep as early as 4.30am.
We would also highly recommend blackout blinds for the most effective blockout method for your windows.
