Standard Curtain Rod Lengths [Chart Included]

You want to know, do curtain rods come in standard lengths, and what are those? Let’s take a look at the typical sizes of curtain rods in this post. We’ve checked with experts and have the answers for you below.

The standard size lengths of curtain rods relate to the standard sizes of windows. Rods are usually extendible, so each rod has a minimum and maximum length. You can adjust the rod to fit any window that falls within that range. Typically curtain rod lengths are as follows:

  • 28″-48″
  • 48″-84″
  • 66″-120″
  • 120″-170″

We’ll explore this a bit more in-depth. We’ll also talk about the right diameter for curtain rods, how to hang extra long curtain rods (and what those are), and if you need to install your curtain rod into a stud or not. So please, keep reading.

66-120″ Curtain Rods

Any rod longer than 60″ is considered an extra long rod, which means further consideration should occur for security when installing. These longer rods are needed when you’re covering a bank of windows, french doors, or patio doors, which are typically in the 80″ range. Depending upon the type of curtain you’re hanging, you may want a heavier diameter rod.

This heavy-duty 1″ drapery rod extends from 66″-120″. For rods like this, make sure you use an additional support bracket in the center so you don’t end up with sagging or buckling from the curtains’ weight.

What Diameter Should A Curtain Rod Be?

There are two things to think about when choosing the diameter of your curtain rod. First, is it sturdy enough for your curtains so that it doesn’t bow. And second, will it fit inside of the curtain hem or tabs of the curtains you chose. Anything much smaller than 5/8″ might tend to bow if you’re hanging curtains heavier than sheers. A good 1″ curtain rod in a metal can hold heavier curtains.

This 1″ diameter metal rod curtain can hold up to 22 lbs. of fabric. That’s a nice heavy-duty rod. It comes in two telescoping lengths, either 36-72″ or 72-144″.

How Do You Install Extra Long Curtain Rods?

When you have a large window, you will need extra support. Curtain rods that go beyond 60″ or 5 feet will need a third bracket in the center of the window. This will keep your curtain rod from sagging. You want it placed in the center so that when you close your curtains, they still close properly. We found a short video to help you with this installation.

  • You’ll need to measure the entire length of your window, then add about 6″ to either side for your end bracket places. Then divide the window width plus those additional 12″ and divide to find the spot for your center bracket.
  • Decide how far above your window you want the brackets to go and mark the spots for your brackets.
  • Make sure your marks are level
  • Drill holes for your wall anchors
  • Put them into place with a mallet
  • Screw brackets into wall anchors
  • Place your curtain rod and curtains in place

What Is The Proper Placement Of Curtain Rods?

The placement of your curtain rods should be centered on your windows. You want space on the sides of the windows for the curtains to rest against the wall when opened (not blocking the window). Typically this adds anywhere from 3″ on each side to 6″ on each side. This measurement can be based on personal taste, the mass of curtains, or the room available to you on your window wall.

As for the height above the window, that is a bit more personal. Curtains hung from near the ceiling can create a sense of height and spaciousness in a low ceiling room. If this is the choice, then hang the rod near the ceiling, leaving room for the rod finials and curtains to close without snagging on the ceiling. 

The other option is a more standard installation. Your curtain rod should be installed anywhere from 3-6″ above the window frame as a general rule.

Do Curtain Rods Need To Be Hung On Studs?

While it is optimal to hang a curtain rod on a stud, that may not be an option to get the curtain rod hung correctly in relation to the window. That’s why the use of wall anchors is recommended. Wall anchors grip into drywall, providing a very sturdy method for hanging heavier objects. Even if your wall could hold a curtain rod and curtains, the constant opening and closing could eventually pull the rods loose without the use of wall anchors.

White plastic wall anchors screw into sheetrock, giving a solid spot for screws to be screwed in. Kits like this are a handy thing to have in your homeowners DIY kit.
