Hang Curtains to Make Your Window Look Bigger

When it comes to hanging curtains, we always recommend going high and wide to visually enlarge the window and add height and drama to any room. Like a fresh coat of paint, floor-to-ceiling curtain panels instantly make a space feel more finished. Below is a simple, practical method for hanging curtains that works well and is easy to follow. There are many ways to do this, but this approach consistently delivers great results.

Here’s the window before curtains. The rectangular frame looks harsh and the bare wall feels unfinished — an easy fix with a few well-placed curtain panels.

before curtains

First, decide how high and wide to hang the rod. In this room with 9-foot ceilings we didn’t mount the rod right at the ceiling; instead we placed it 12 inches above the top of the window and extended the rod 12 inches past each side of the window. This extra height and width visually enlarges the window and allows the curtains to stack neatly off the glass when open.

measuring curtain rod

Before installing the brackets, make sure the rod extends far enough. Lay the rod on the floor in front of the window and measure the target width (window width plus the extra 12 inches on each side) to confirm the rod length. Once the length is confirmed, use a level to mark a point 12 inches above the top corner of the window on each side and mark those spots lightly with a pencil.

Pre-drill small holes for plastic anchors, tap the anchors into place, then drive screws into the anchors to secure the rod brackets. This method ensures a solid hold, even if you’re attaching to drywall rather than studs.

For longer rods, add a center support bracket to prevent sagging. Measure and mark the center point above the window, place the bracket there, and secure it the same way with an anchor and screw. This extra support keeps the rod straight and reduces wear on the hardware.

Here’s the finished result: billowy, floor-length curtains that can be hemmed to skim the floor or left to pool slightly if you prefer that look. While colored or patterned curtains would add visual interest, a matching white-on-white treatment offers a clean, cohesive look that subtly draws the eye through the window. Hanging curtains slightly above and beyond the window frame creates an uninterrupted visual flow and enhances perceived height. Mission accomplished.

after curtains

Many people worry about the space between the top of the rod and the window, but that gap often looks balanced and intentional. Mounting the rod directly on the window frame can make the window feel cramped. If you want to conceal a larger gap, you can layer a shade behind the curtain for extra coverage and texture.

This quick curtain-hanging project is easy to complete with a ruler, level, and drill — you can get it done in about 30 minutes and achieve a polished, elevated look.
