Customize Curtain Rod Length Affordably with Galvanized Pipe
Finding ready-made extra long curtain rods can be a frustrating endeavor. Standard sizes just don't work for floor-to-ceiling or two-story windows. And rods longer than 144 inches are often special order at extreme costs. But with a trip to the hardware store and some simple DIY, you can create custom curtain rods in any length you need affordably.
By using basic galvanized steel pipes and connectors, you can build your own rods that are cut precisely to size. It's an easy weekend project that will save you time and money searching for the perfect oversized curtain rod.

Finding the Right Length Pre-Made Rods is Hard
Trying to find pre-made extra long curtain rods often ends in disappointment. Big box stores rarely carry lengths over 120 inches due to limited demand. Even if you find a specialty shop with larger sizes, the costs are astronomical.
For example, a 144-inch rod can run $200 to $300. And good luck finding off-the-shelf rods longer than that without going full custom order. Measure across your wide window or sliding door. Now add extra length on both sides for the end mounts. You'll quickly see why DIY is the way to go.
Measure Your Opening and Account for Extra Length
First, measure the full width across the top of your window or door opening. For height, measure from the top of the frame to where you want the rod mounted below the crown molding or ceiling.
Add at least 3 inches on both sides of the window opening measurement. This allows space for the end brackets that mount your rod. If your brackets are larger, allow extra room. You can always trim later for a perfect custom fit.
Galvanized Pipe Offers Versatile Low-Cost Alternative
For an affordable solution, use galvanized steel pipes for your DIY curtain rods. Galvanized pipe is coated in zinc to resist rust and corrosion. This makes it perfect for both indoor and outdoor use. It comes in various diameters and wall thicknesses to support heavy curtains.
You can find galvanized pipe at any hardware store or plumbing supply company, often for less than $10 for a 10-foot length. Since it's sold by the foot, you only buy as much as you need without waste. For custom curtain rods, 1/2-inch or 3/4-inch diameter pipes work well. Go with a thicker sch40 rating for heavyweight fabrics.
Things You'll Need
To make your own custom length galvanized pipe curtain rods, you'll need:
- Galvanized steel pipes (1/2" or 3/4" diameter)
- End cap fittings
- Pipe flanges or L-brackets for mounting
- Hacksaw and/or pipe cutters
- Metal file, sandpaper
- Spray paint or clear coat (optional)
Pipe flanges allow you to mount the rods flat against the wall. L-brackets provide a little separation. Pick whichever matches your decor. The total cost for materials will run you less than $20 in most cases.
Measure Window and Cut Pipe to Length
Use your window measurements to mark where you'll make the cuts on each pipe. Allow for the extra length on each side you calculated earlier. You can run a single pipe for smaller windows. For larger widths, use pipe connectors to join multiple pieces.
A hacksaw with a metal blade makes quick work of slicing galvanized pipe to size. Use a vice or clamps to secure the pipe while cutting. A pipe cutter is another option that creates very straight edges. Take your time to measure twice and cut once.
Allow Length for Mounting Brackets on Each End
Don't forget to include the extra length on both ends of your pipe to accommodate the brackets. Wall-mounted brackets add a couple inches. Ceiling mounts require allowing for the drop distance. Measure first before cutting to your window's exact size.
You can always trim later if needed, but you can't add length back on. Leaving a little extra ensures your brackets will fit flush.
Smooth and Finish Cut Edges
For safety and appearance, take a few minutes to smooth any sharp burrs or edges on your cut pipe. Use a metal file, sandpaper, or edge deburring tool. Wipe away any metal debris when done. Dull edges won't snag curtains or hands.
Spray painting the pipe with a metallic finish like oil-rubbed bronze or brushed nickel gives a more polished look. For rust prevention, apply a clear topcoat. Plastic end caps provide a nice finished touch on each end.
Remove Sharp Edges and Add Finishing Touches
Take the extra time to clean up cut edges so curtains glide smoothly and fingers stay snag-free. Spray paint, clear coat, and end caps finish off the DIY pipe curtain rods with style.
Sand down any burrs or sharp edges from cutting with medium grit sandpaper. Wipe away metal dust before continuing. Plastic end caps provide a clean, finished look and eliminate sharp ends.
Mounting Your Custom Curtain Rod
Installing your custom DIY curtain rods is much like traditional rods. Determine desired height and mark bracket locations evenly spaced. Use wall anchors in drywall or studs for a secure mount. Slide rod through brackets and tighten all fasteners.
Check that your custom rod length still fits properly in the space before finalizing. Make any adjustments needed to end length. Install any finials or decorative hardware on the ends. Hang your curtains and enjoy perfectly sized rods on a budget!
Test Fit Before Permanently Mounting
Before committing with permanent fasteners, temporarily set the brackets and test fit your rod. Make sure it aligns properly and adjust length or bracket positions as needed. This allows you to fine tune the perfect custom fit.
Enjoy Your Custom Curtains!
Once your new galvanized pipe rods are mounted, it's time to enjoy your oversized curtains without the giant price tag. Change them out seasonally or when it's time to redecorate easily. And you'll always have the right length rods on hand for your space.
With basic DIY skills and minimal cost, you can tackle any custom window size. Ditch the tiny off-the-rack rods. And avoid the outrageous quotes from special order shops. Craft your own curtain rods to the perfect length affordably.
Your custom curtain rods allow you to easily change your look. Swap out bold patterns for breezy sheers in summer months. Go back to rich solids or thermal blackouts in winter. Update colors and styles for pennies without special ordering rods each time.
