Installing a curtain rod is a quick, beginner DIY job of about 30 minutes per window with a drill, a level and the right anchors, costing only the price of the rod and hardware. No permit or pro is involved and the load is light. The skill is in two things: getting the brackets level with each other so the rod hangs straight, and choosing anchors that actually hold, plus a center support on any long rod. Get those right and the rod stays put and looks intentional.

How to Hang Curtain Rods — The Home Depot

Step-by-step: a level, secure rod

  1. Choose height and width. Mark the rod height 4 to 6 inches above the trim, or higher, and plan to extend 8 to 12 inches past each side.
  2. Mark the first bracket. Position one end bracket about 3 to 4 inches in from where the rod end will be, and mark its screw holes.
  3. Level across to the second. Use a level or laser to carry that exact height to the other end and mark the second bracket on the same line.
  4. Check for studs. Where a bracket lands on a stud, plan a direct screw. Elsewhere, plan a threaded drywall anchor.
  5. Drill and set anchors. Drill the marked holes, tap or drive in the anchors, keeping the drill level so holes are clean.
  6. Mount the end brackets. Screw both end brackets firmly and confirm they are level with each other.
  7. Add a center support. For any rod over 48 inches, mount a center bracket midway. Add a second past 90 inches.
  8. Hang the rod. Slide panels on, set the rod in the brackets, and confirm it sits level and does not bow.

Tools and materials

You need a drill/driver, level, tape measure, pencil and drywall anchors sized to the rod. A curtain rod is one layer of a finished room, so plan its height and projection alongside the furniture at the window, such as a reading chair from our accent chair picks, or a desk placed to catch the light from our standing desk roundup. Setting the rod high and wide makes the whole wall and its furniture read as taller and more deliberate.

Notes

This is fully DIY and low-risk. The only cautions are avoiding hidden wiring or pipes when drilling near a window jamb, using rated anchors and a center support for heavy drapery so nothing pulls loose, and choosing cordless or corded-cleat window coverings where young children are present, since looped cords are a recognized CPSC hazard. No codes govern a curtain rod, so the risk is limited to a crooked rod or a patch-and-repaint if a hole goes wrong.

Straight Answers

Frequently Asked

What anchors do you need for a curtain rod?

Where a bracket lands on a stud, a wood screw straight into the stud is strongest and needs no anchor. Where it lands on hollow drywall, use a self-drilling threaded drywall anchor for light-to-medium curtains, or a heavier metal toggle bolt for heavy drapery. Skip the flimsy plastic conical anchors that come in some kits, since they strip out of drywall under the outward pull of a loaded rod. The bracket carries the weight of the rod plus fabric, and heavy blackout or velvet panels put real load on the ends.

How far apart should curtain rod brackets be?

Set the end brackets about 3 to 4 inches in from the ends of the rod so the finials have clearance. The critical rule is the center support: on any rod longer than about 48 inches, add a center bracket to stop the rod bowing under fabric weight, and use two center supports past 90 inches. The most common curtain-rod failure is a long rod with no middle support that sags in the center and eventually tears its end brackets out of the drywall as the fabric pulls down.

How high above the window should you install a curtain rod?

Mount the rod 4 to 6 inches above the window trim, or higher toward the ceiling if you want to make the window and room look taller. Extend it 8 to 12 inches past each side of the frame so panels clear the glass when open. These placement choices matter more to how the room looks than the drilling does, so measure and mark before you commit. A rod installed right at the trim and cut flush to the frame makes a window look short and blocks light when the curtains are drawn back.

How do you install a curtain rod straight?

Mark one bracket height, then use a level to carry that exact height across to the other bracket, drawing a light horizontal reference line or using a laser level. Mark both bracket hole positions on that line before drilling anything. A rod that is even slightly off level is glaringly obvious once panels hang and gravity makes the tilt visible. Do not measure up from the window trim on each side independently, because trim is often not perfectly level itself, which is how crooked rods happen.

Can you install a curtain rod without drilling into studs?

Yes, and most curtain rods are installed into drywall anchors rather than studs, because the load is modest and studs rarely line up with where the brackets need to go. Use quality self-drilling threaded anchors rated for the rod-plus-fabric weight, and the install will be solid for standard curtains. For heavy drapery on a long span, add a center support and use metal toggle bolts, or catch a stud where one happens to fall. Tension rods need no drilling at all but only suit light curtains inside a window recess.
