Make Sure the Curtains Are Long Enough

When making curtain length rules, you should pay attention, logically, to the length. The length of the curtain is a vital factor in the design of your home.

When you plan to hang a curtain, do you have an idea of the final picture? Of course, we understand that you’re not an interior designer.

But surely you want to achieve some effect. So, it’s essential to know what length of curtains is appropriate for your situation.

Fortunately, there are several standard curtain sizes available. Each of them is suitable for different decor and uses.

Want to determine which one is best for you? Read our curtain-length rules.

There are four basic types of curtain lengths:

  • Window sill curtains. It is the shortest type of curtain. You can use it for small windows, for example, in the kitchen or bathroom. 
  • Apron curtains. This type of curtain is usually slightly longer than the window sill. They are often hung on the lower half of the window. In this way, they provide more privacy. But they allow natural light into the room.
  • Floor-length curtains. You can tell from the name that these are floor-length curtains. This type of curtain length is usually used in living rooms. Some people also like them in bedrooms or dining rooms. You can use them to add elegance and sophistication to these rooms.
  • Puddling curtains. It is the longest type of curtain. They are designed to create a dramatic, elegant look. They allow the bottom of the curtain to “puddle” or gather on the floor. Puddling curtains are best used in tall rooms or with high ceilings.

If you still need to figure out the ideal curtain length for your window, there are some rules you can follow.

Consider taking the window’s height and width measurements. The curtains should be hung lower than you originally intended. It will raise the ceiling higher.

Or you could go the other way. The curtains would seem more attractive if you hung them near the ceiling.

Curtain Rod Size Matters

Another important length selection rule when installing curtains is the curtain rod. Yes, you read that right; the type and size of the curtain track are essential.

The type and size of the curtain rod depend on the material of your curtains. Let’s start with the kind of curtain track. When choosing one, take into account the following:

  • The style of your room.
  • The weight of your curtains.
  • The amount of space available. 

Select a curtain track with a thicker diameter if your curtains are heavy. Look for strong brackets as well.

Opt for a smooth, simple curtain rod for a more modern look. Choose a rod with ornamental inlays for a more conventional appearance.

To determine what size you need, you need to know the following:

  • The length of the window.
  • The width of the curtain.
  • The height of the awning. 

For most curtains, the top of the rod should be about one to two inches above the floor. This length rule of thumb allows you to clean the curtains easily.

Consider raising the curtain rod a little higher if you have a wide window. This way, the curtain will appear larger.

Another important aspect is the curtain rod’s diameter. Denser fabric curtains need a larger diameter to maintain their weight. Additionally, for the curtain rod to seem flat, it must have a lower diameter on one side.

The ledge is usually attached between the ceiling and the window frame. You need to measure the dimensions correctly.

You can use a tape measure or a ruler when measuring. Remember to mark the measurements to the nearest 1/16th of an inch. Only then will you be able to draw the correct length of curtains according to the rules.

You can find curtain rods in several different materials.

These can include:

  • Metal. They are flexible and sturdy.
  • Wooden. They are natural and durable.
  • Aluminum. They are inexpensive and easy to install.

The curtain rails are also available in large lengths. For example, extra-long ledges are designed to support a lot of weight. They are usually longer than 60 inches and come in a set of two. It is a good option for large windows.

Don’t Skimp on Fabric

Fabrics for curtains and room design


One of the easiest ways to add style and elegance to your home is with suitable fabric. It’s not uncommon to see a modern living room decorated with curtains.

But you can create a designer look using curtain length rules. Here are some tips to help you make the most of your new curtains.

Firstly, if you are buying ready-made curtains, check the dimensions. You won’t be able to achieve a perfect fit, but you can be careful when cutting.

If you decide to make the curtains, feel free to go to a fabric shop. Fabric is not cheap, but you’ll be able to find the perfect one for you. Remember that different types of fabric need to be chosen carefully.

A good rule is to buy a few more yards than you’ll need.

You will need two pieces of fabric for one curtain. So make sure of the curtain length rules. You must have enough fabric to work with.

Using two different contrasting fabrics will give you a more beautiful and cohesive finished product. You can sew two panels together with a double needle for a unique look.

To test this theory, make a small list of your favorite fabrics. Get a few samples. Try matching the fabric to your furniture. That way, you can create a seamless look. Be a wise shopper, and you may end up with a work of art.

How to Measure Curtains Properly

How to Measure Curtains Properly


There are several important rules to follow when measuring curtain lengths. They can make a big difference in the appearance of the room.

If you are ordering a bespoke curtain set or just measuring a standard size, the following tips will help you achieve the best results.

First, measure the width of the window. It should be at least 1.5 times the width of the curtain. Also, add six inches to the bottom of the curtain for overlap.

If you want to create different types of curtains, you may not need to add this extra width.

Measure the length from the top of the curtain rod pocket to the end. Then find the end of the curtain rod.

We recommend using a metal tape measure for accuracy. Also, consider the height of the ceiling to create the length of the curtains according to the rules.

When you are finished, you will have a set of measurements. You can use these to calculate the width and fullness of the curtains. Ideally, you should have two panels, each at least 30 inches wide.

Adding fullness will create an attractive finish. You can increase the fullness by adding three to five inches to the end of the rod. The finished length of the curtain should be at least 10 inches above the trim.

Several different rods will allow you to hang different types of curtains. Make sure you choose the right one for your needs.


Can I shorten the curtain panels?

Yes, you can shorten the curtain panels. However, it is vital to make sure that you cut them evenly. And, of course, remember to follow the curtain length rules.

What is the best curtain length for my living room?

The length of the curtains depends on several factors.

More specifically, consider the size of the window and the height of the ceiling. Generally, we recommend a curtain length of 60 inches or more for the living room.

It creates a luxurious long look that will make your room seem larger.

Can curtains be too long?

Yes, curtains can be too long. You can get this problem if you don't follow the curtain length rules.

If the curtain is too long, it will look unbalanced and drag on the floor. It can cause a mess and clutter the room. It is best to exercise caution when measuring curtain lengths.


Curtain rails are a vital part of any room. They help to make a room look clean and organized.

They also give it a particular style. Putting up curtains is a reasonably simple process. It takes some time, but it’s worth it.

Once you hang your curtains, they will make your home more cozy and attractive.
