Longer curtain rods make the window look larger than it is. As a rule of thumb: choose a curtain rod 8–12 inches (20–30 cm) wider than your window.
Avoid letting more than 1–2 inches (2. 5–5. 1 cm) of curtain pool on the floor.
In most cases, the right brackets and screws will come with your curtain rod.
If the bubble floats in between the two marked lines on your level, your area is straight. Straight edges combine levels with measuring tape and can make a useful alternative.
Base the hole size on the size of your screws. Each hole should be identical in size to the screw’s body.
To use a stud finder, run the device along the wall and watch the screen to see if a stud has been detected.
The holes drilled for the wall anchors should be separate from the holes drilled for the screws earlier. Avoid making the hole wider than the anchor. The hole should be about the same length as the anchor’s attachment areas to avoid loose wall anchors.
If the brackets seem loose or if they seem to move slightly under the rod’s weight, they are probably not strong enough to support the curtain rod.
If your curtains are too heavy for the brackets, you may need heavy-duty brackets or a rod with added support. [9] X Research source
