You can break down curtain sizes into width and length, also known as the drop.

Additionally, the type of window and the style of your home will help you determine the best choice.  

Ready-made curtains available will typically come in many different widths, including: 

  • 44 inches
  • 54 inches
  • 66 inches
  • 80 inches
  • 90 inches
  • 108 inches
  • 135 inches
  • 162 inches

The length of ready-made curtains will vary, depending on the window and decor. These sizes include: 

  • 54 inches
  • 63 inches
  • 72 inches
  • 84 inches
  • 90 inches
  • 108 inches
  • 120 inches

Of course, you can alter the curtain materials to custom-fit a window that does not accommodate these measurements.

Curtains are an investment in your home, so they should be attractive and functional to enjoy for years. 

Curtain Sizes in Detail

Choosing the correct curtain sizes can benefit your home in several ways. If you have inadequate curtains, they may not block out sunlight, offer privacy, or give your room the style you want. 

Insufficient curtains may also have problems when opening or closing, causing functionality issues. You will not want to spend money on window treatments that do not serve their purpose or look awkward in your home. 

Once you know how to measure the proper curtain width and length, you are sure to find the best material to suit your windows and home decorating needs.

Again, this process is easy to do once you know how to begin. 

How to Determine the Curtain Width 

You can have various widths of curtains to provide ample coverage for privacy and light protection. Finding the ideal width will be necessary before purchasing any materials. 

The style of curtains will also be a factor in how wide they should be. For example, flat-out curtains will not completely cover a window until you measure more material than the window size. 

However, other types with built-in pleats will adequately cover your window when choosing a width identical to the curtain rod. 

So how do you determine the curtain width you need? It’s easy to do, so you can have the correct curtain sizes in no time. 

Step 1: Measure the Curtain Rod Length

First, measure the entire length of the curtain rod. The style will indicate how much more material you will need to provide fullness and depth. 

Step 2: Multiply the Measurement 

Next, double or triple the rod measurement. By doing this, you will add enough curtain fabric to cover the window and have an ample stack back at the edges when they are fully open. 

How to Determine the Curtain Length 

Not all curtains will suit every room, unfortunately. However, these various lengths will work in different areas of your home perfectly. 

  • Window Sill Curtains: Suitable for small windows in bathrooms or kitchens
  • Apron Curtains: Hang approximately four inches below the window sill, ideal for breakfast nooks or rooms with a radiator under a window
  • Floor-length Curtains: Formal window coverings that will either float an inch above the floor or kiss the floor, perfect for living rooms or sitting areas 
  • Puddling Curtains: Provides a romantic feel, these curtains are incredibly long and puddle or pool on the floor, found in bedrooms or other common rooms

Follow these steps to measure the length of material you will need for new curtains in your home. 

Step 1: Position Your Curtain Rod

As a general guideline, rods should be at the very least four inches above the window frame, but you can go higher toward the ceiling.

In small spaces, you may want to hang curtain rods higher and extend them longer to give the illusion of oversized windows once your curtains are in place. 

Step 2: Start At the Curtain Rod

Begin at the curtain rod and measure down to the point where you want the curtains to fall. Remember to take multiple measurements along the entire rod in the event of any uneven areas.

Things to Consider

By keeping these points in mind, you will find the best way to determine the measurements for new window treatments. 

  • Do not measure the window or window frame for size, but rather stick to the curtain rod for an accurate measurement
  • Curtains that puddle on the floor will be more challenging to open and close and will collect dust easier than ones that hang 
  • Sheer curtains will generally need three times more fabric when hanging to add enough depth, while pleated material will not
  • Take multiple measurements along the rod since many homes are not precisely level, and this can affect how the material looks once you hang curtains
  • Avoid curtain sizes that are too short or narrow, as these will look awkward and not suit the window 
  • Take into account the extra material necessary when using a wrap-around curtain rod so they won’t fall short, leaving gaps 

It isn’t tricky to measure curtain sizes for your home, but you will want to measure more than once to ensure the final number before purchasing materials and avoid any possible regret.

Frequently Asked Questions

If you have any other questions regarding curtain sizes, take a look at these frequently asked questions for more information. 

How Do I Read Curtain Sizes?

If you are shopping for new curtains, the sizes a manufacturer lists will always be width first and length second. This format is standard in the industry.

So you are certain to find suitable curtain sizes for your windows when you have the correct measurements. Likewise, curtains will typically come in a set of two unless otherwise stated on the manufacturer’s label.

How Can I Figure Out What Curtain Sizes to Buy?

First, measure the curtain rod from left to right. Then, take the resulting measurement and multiply it by two or three, depending on how much extra material you want for a fuller look.

Next, measure from the curtain rod to the space where your curtains will hang below. These two figures will give you an indication of the size you need for your window.

Is the Width of Ready-Made Curtains for Each Panel or a Total Size?

When shopping for ready-made curtains, the manufacturer’s measurements they provide are the width of each panel of material.

Therefore, if you have two curtain panels where each measures 54 inches, the set will measure 108 inches total. Be sure to read the manufacturer’s packaging for single and double packaging specifications.

Do Eyelet Curtains Need to Be Double Width?

When fastening eyelet curtain material, you will not want them to hang flat. However, the eyelets do not stay flat against the curtain rod when completely extended.

So you want to add depth with additional material. By doubling the width of eyelet curtains, you ensure that they will sit on the rod correctly in position and provide extra volume.

So, What Are Average Curtain Sizes?

Knowing how to measure and read curtain sizes is essential when you want to add or alter your window coverings. 

Curtains come in a wide range of standard sizes, but they are simple to customize by modifying longer panels for the perfect width and length. 

Do not sacrifice style by using incorrect curtain sizes for your home. Having the correct measurements is vital when you have enough material to close your curtains and still give them a fuller look for added beauty. 

This task is easy to do on your own and can help you decide on new window treatments if you need a change.
