Common Mistakes To Avoid When Hanging Blackout Curtains

By admin – Dec 30,2022 | Blog, Curtains Installation Guide | Share:

Blackout curtains are a great way to reduce light and noise, maintain privacy, and even help regulate temperature in your home. But if you don’t hang your blackout curtains correctly, they won’t do their job as effectively. To help you get the most out of your blackout curtains, it’s important to be aware of the common mistakes people make when hanging them. In this blog post, we’ll be discussing the common mistakes to avoid when hanging blackout curtains so that you can ensure they are hung correctly and enjoy their benefits.

Not Measuring The Windows First

Before you start hanging your blackout curtains, make sure that you measure the windows accurately. Without knowing the exact dimensions of your windows, you won’t be able to get the right size of blackout curtains or know where to hang the rods and brackets. Measure the width and height of your window frames and use this information when purchasing your blackout curtains. Also, make sure that you double check the measurements before you buy. It’s better to be safe than sorry!

Mounting The Curtain Rod Too High

One of the most common mistakes people make when hanging blackout curtains is mounting the curtain rod too high. Blackout curtains are designed to block out light and keep the room dark, but if you hang the curtain rod too high, it won’t be able to do its job effectively. When measuring the height of the window, make sure to measure from the top of the window frame to the floor. 

Then, subtract two or three inches from that measurement to determine where the top of the curtains should hang. If you’re using a rod, make sure it’s mounted at least two or three inches below your measurement. This will ensure that your blackout curtains are hanging at the right height.

Making Your Blackout Curtains Too Long

It’s easy to make the mistake of getting blackout curtains that are too long for your windows. Blackout curtains come in various lengths, and it’s important to measure your windows before you buy curtains so that you don’t end up with ones that are too long. When your curtains are too long, they can bunch up at the bottom or pool on the floor, which will not only look unsightly but will also prevent them from doing their job effectively.

If you find yourself with blackout curtains that are too long for your windows, there are ways to fix them. You can hem the curtains to the correct length or tie them back. Another option is to use a decorative rod at the top of your window to pull the curtain away from the wall and create a swag effect. However, it’s best to avoid this situation altogether by measuring your windows before buying your curtains.

Not Hanging The Curtains High Enough

The general rule of thumb is to hang them as high as possible above the window, while making sure they extend beyond the window on both sides. And it’s not about hanging too high. This helps to block out any light that may be coming in around the edges of the curtains. Not only will this provide more light blocking capabilities, but it can also make the window look larger and more dramatic. Additionally, it will help create an air of luxury and grandeur in the room. Make sure to measure your window before you purchase your curtains and hang them at least 6-8 inches higher than the top of the window frame. Doing so will ensure that you get the most out of your blackout curtains.

Not Using Command Hooks

When it comes to hanging blackout curtains, command hooks can be a lifesaver. They help keep your curtains in place and make them easier to adjust. However, many people forget to use them or don’t even know what they are. Command hooks are small plastic hooks that adhere to surfaces and can hold up to 3 pounds of weight. They are perfect for mounting your curtain rod and make it easy to adjust the height of your curtains without having to drill holes in your wall. If you’re not using command hooks when you hang your blackout curtains, you’re missing out on an easy way to make sure your curtains stay in place and look their best.

Not Matching Your Curtains To Your Decor

When your curtains don’t match your existing furnishings, they can stick out like a sore thumb and detract from the overall look of the room. There are several ways you can match your curtains to your existing decor. First, consider the color scheme of the room. If your room has a neutral color scheme, for example, look for blackout curtains in a neutral color that will blend in with the rest of the room. You can also choose curtains in a bolder color that will provide a nice contrast to the existing decor. Additionally, you can opt for patterned curtains if you want to add some visual interest.

Finally, make sure the fabric you choose for your blackout curtains works with the style of your room. For example, if you have an eclectic-style room, consider using lightweight linen or sheer fabrics. On the other hand, if you have a more traditional style room, heavier velvet or damask fabrics may work better. No matter what kind of blackout curtains you choose, make sure they match your existing decor to ensure they look cohesive and stylish.

Using The Wrong Rods And Brackets

The wrong rods and brackets can affect the way your curtains hang and can prevent them from properly blocking out the light. It’s important to choose a rod and bracket that is strong enough to hold the weight of your curtains. If you’re using a curtain rod, you’ll want one that is at least 1⁄2” thick or more. You also need to make sure that your brackets are securely installed and properly spaced for the width of your curtains. 

If you’re using a tension rod, you need to ensure that it’s installed securely so that it doesn’t slip when you hang the curtains. Finally, make sure that the screws used to attach your brackets and rod to the wall are appropriate for the type of wall material you have (drywall, plaster, etc.). Taking these steps will help ensure that your blackout curtains hang properly and remain secure.

Not reading the instructions

When it comes to hanging blackout curtains, it’s important to read the instructions that come with them. The instructions will help you determine how to properly hang the curtains and what kind of curtain rod or brackets you need. 

Many people try to guess how the curtains should be hung and end up making mistakes that could easily be avoided. Reading the instructions can also help you determine the best type of hooks or nails to use for the installation. 

If you’re unsure about something, make sure to double-check the instructions before proceeding. For example, if the instructions indicate that the curtains should be hung from a certain height, measure that height and make sure that your measurements are accurate before installing them. By taking the time to read the instructions, you can ensure that your blackout curtains are installed correctly and look their best.

Putting Only One Panel On Each Window

If you are hanging blackout curtains, it is important to ensure that each window has two panels. This is because the two panels will overlap in the middle and help to block out light more effectively than if you were to just hang one panel per window. Not only does this make for better insulation, but it also looks better aesthetically. To avoid this mistake, measure your window and purchase curtains that are the right size for your window, then hang two panels. This will help you get the best possible look and function from your blackout curtains.


Hanging blackout curtains is a great way to increase the comfort of your home. By avoiding common mistakes when installing your curtains, you can ensure that you get the most out of your blackout curtains. Start by properly measuring your windows, making sure you purchase the correct length for your window size. Use the appropriate rods and brackets, and don’t forget to use command hooks for a secure fit. 

When it comes to decorating, pick blackout curtains that match the color scheme of your room. Be sure to read the instructions before hanging the curtains, and never hang only one panel on each window. Following these tips will help you make the most of your blackout curtains and enjoy the extra comfort they provide.
