How to Hang Eclipse Blackout Grommet Curtains for Full Coverage

Get full blackout coverage from grommet curtains by placing the rod high and wide, sizing for fullness, and closing the gaps at the floor, ceiling, and sides.

Quick answer

Mount the rod 4–6 inches above the window frame and 6–12 inches wider than the frame on each side, then choose panels wide enough to close with soft folds. Grommet curtains only block light fully when the rod extends past the glass and the panels overlap or meet without gaps.

Why grommet curtains leak light at the edges

Grommet curtains slide easily, but that same slide leaves the outer edges and the center meeting point vulnerable to light. Blackout fabric blocks light through the cloth; the leaks come from the perimeter. The rod position and panel width decide whether the room stays dark at 6 a.m.

When full coverage is not the goal

If you want a softer daytime look and only need light reduction, a rod just above the frame and panels that barely cover the glass can be enough. Full blackout coverage matters most in bedrooms, nurseries, and media rooms where light wakes sleepers or washes out a screen.

Step-by-step hanging process

Measure the window and decide the coverage zone: Measure the glass width and height, then add 6–12 inches on each side and 4–6 inches above the frame for the rod span. Check that the rod clears any valance or ceiling trim. Write the final rod length and height on the wall with painter's tape before drilling.
Choose a rod diameter that fits the grommets: Grommet openings are typically 1.5–2 inches, so a rod about 1 inch in diameter slides freely without excess wobble. Confirm the rod's diameter before buying brackets. Test one grommet on the rod end; if it drags, size down the rod.
Mount the brackets at the marked height and width: Use wall anchors rated for the rod and curtain weight, and keep brackets level. Place them at the ends of the rod span, not at the window frame, so the panels can cover the extra width. A level rod prevents the panels from drifting open on their own.
Hang panels wide enough for fullness: For a gathered look, total panel width should be about 1.5–2 times the rod span. For a flat, modern look, closer to 1.25 times is enough, but expect less light control at the edges. If the panels stretch flat when closed, they are too narrow for full coverage.
Close the center and side gaps: Overlap the two panels by 2–4 inches at the center, or use a return bracket or wrap-around rod to push the outer edges against the wall. Check the top and bottom for light stripes. Stand in the darkest corner at night with the room light on to spot leaks.
Set the bottom hem and test the slide: Hem or adjust the length so the panels just touch the floor or hover 1/2 inch above it. Open and close the curtains a few times to confirm the grommets glide and the panels still meet. If the panels catch at the brackets, add a center support or reposition the bracket.
