Blinds can be both functional and aesthetic additions to any home. They protect your privacy while also providing a decorative flourish. Covering windows with carefully selected blinds is certainly a move worth considering.

The blinds will look even better over your windows if they fit perfectly. Unfortunately, finding the right set can be difficult if you have small or irregularly sized windows. You may have to shorten the blinds manually in order to get the right fit.

Begin the process of shortening the cordless mini blinds by seeing how the set fits over your window. From there, you can select a new bottom slat and move the bottom rail up to match with it. Removing the excess slats and ladder cord will also be necessary if you want to ensure that the blinds work properly.

New blinds can be terrific household accessories, but that can only happen if they fit the right way. Work on adjusting the fit yourself by shortening the blinds manually. Find out all you need to know about shortening cordless mini blinds by reading on.

Why Do You Need to Shorten Your Cordless Mini Blinds?

There are two main reasons why you should shorten cordless mini blinds that hang well past your window. Let’s discuss them in greater detail below.


Blinds that are excessively big for windows are not great to look at. They look like an oversized dress that’s dragging along the surface of the ground.

Furthermore, long blinds may actively take away from your home décor. Instead of highlighting the ornate decorative elements along your windows, the long blinds will just obscure them. You’re doing your home décor a disservice by using excessively long blinds.


If you have toddlers at home, you are probably all too familiar with their ability to create a mess. It’s hard to blame them though because they don’t really know what they’re doing.

Toddlers are very curious and they will check out anything within reach. Upon getting their hands on the excess blinds, they may start playing around with them. That’s scary because they could get all tied up in the cords. If they pull forcefully on the blinds, the set may also fall down on them.

To put it simply, excessively long blinds pose a threat to curious children. You need to keep those blinds at the right length and keep them away from kids.

Shortening Cordless Mini Blinds

The process of shortening cordless mini blinds isn’t that difficult, but it can be tricky. One mistake could ruin the blinds for good and force you to purchase a replacement set. Follow the steps detailed below carefully to ensure no problems arise.

Step 1: Prepare Your Tools

The essential tools for this job are scissors and pliers. Depending on what kind of blinds you, you may also require a putty knife.

Step 2: Fully Extend the Blinds

For the purposes of this project, we’re assuming that the blinds are already installed over your window. If they aren’t, pull out the instruction manual and install the blinds first. You cannot proceed without knowing how the blinds extend over your window.

With the blinds in position, you should now let them hang down completely. Get rid of any tangles along the lift cords so you get the full picture.

Step 3: Identify the New Bottom Slat

Now that the blinds are fully extended, you’ll be able to see how they fit over your window. Take a closer look now and see which slat is positioned just beneath the windowsill.

The slat you find positioned closest to the windowsill from underneath will be your new bottom slat. Note its location with an erasable marker or just remember it.

Step 4: Remove the Plugs

Grab the bottom rail of your blinds and look underneath it. There, you’ll find the parts known as the plugs or end caps. The plugs help keep the lift cord and the slats in position. If you want to shorten your blinds, you will have to remove the plugs first.

See if you can remove the plugs by twisting or pulling them out. Don’t try to force them out though because you might damage the bottom rail.

Grab your putty knife instead and use that to get under one side of the plug. Try to pop the plug up carefully. You can also use a small knife if the putty knife cannot fit between the plug and the rail.

Step 5: Remove the Bottom Slat

The next thing you have to do is to remove the bottom slat. In most sets, the bottom slat can be detached from the rail by just sliding it out of position.

Step 6: Take Out the Excess Slats

Next up, you have to remove the excess slats under the new bottom slat you chose earlier. To do that, you will first have to cut some of the lift cords. More specifically, you must cut the horizontal lift cords.

Grab your scissors and start snipping all the horizontal cords beneath the new bottom slat. Remember to cut only the horizontal cords. If you cut the vertical lift cords, you will ruin the blinds.

With the horizontal lift cords beneath the new bottom slat now cut, you should be able to remove the excess slats. Discard the removed slats whichever way you see fit.

Step 7: Get the Bottom Rail into Position

Use whichever mechanism your blinds have to raise the bottom rail. Continue raising the bottom rail until it makes contact with the bottom slat. Take your time raising the bottom rail. You could end up getting the lift cords tangled by trying to raise the rail too quickly.

Step 8: Connect the Lift Cords to the Bottom Rail

Get a hold of the lift cords and start working to connect them to the bottom rail. There should be an opening there that the lift cords can go into. Once inside the opening, pull on the lift cords. Pull them as far as you possibly can to secure them.

Step 9: Cut the Lift Cords to Size

Take a step back now and look at how the blinds look on your window. If you’re happy with how it looks, you can go ahead and trim the lift cords. Trim them until only about four inches of the cord hangs below the bottom rail.

Step 10: Secure the Lift Cords Using the Eyelets

You should find spare eyelets included with your blinds. Get them now and then start threading one length of the lift cord through one eyelet. Continue doing that until all the lift cords have been passed through eyelets.

After threading, you can now push the eyelets into the bottom rail. Use your pliers to properly connect the eyelets. Look at the new setup and see where the lift cords are. If there’s still a good amount of excess cord, you can snip that away as well.

Just remember to leave behind enough of the cord to create a knot. You will need that knot to keep the lift cords in the right positions.

Step 11: Fix the Alignment of the Lift Cords

Now that they are at the right length, you can fix the alignment of the lift cords better. They should be tucked into the bottom rail to do their job correctly. Take this opportunity to straighten them out as well.

Step 12: Put the Bottom Slat inside the Bottom Rail

You can now slide the bottom slat you chose earlier into the bottom rail. Go ahead and reinstall the plugs after sliding the bottom slat into position to finish up.

How Do You Get the Right Measurements for Mini Blinds?

To get the right measurements for your blinds, you first need to determine what kind of set you’re using. Mini blinds are often inside-mounted so you have to take measurements in specific ways.Start by measuring the height of the window. Position your tape measure along the bottom edge of the window’s upper casing and pull it down. Take measurements going from the left, center, and right portions of the window.If the measurements aren’t similar, use the longest one you get. Blinds that are slightly longer than the window are better than ones that are too short. You also need to get the width measurements. Place your tape measure along one inner edge of the window and then extend it to the other side. Do that along the top, center, and bottom portions of the window.Once again, there’s a chance the measurements won’t be the same. In that case, you must stick with the narrowest measurement to ensure the blinds will work properly.You should also check if inside-mounted blinds can be installed on your window by inspecting its depth. Look at the upper edge of the window and see if there’s a flat surface there. Measure how big that flat surface is. You must refer to that measurement later to see if your window can accommodate the headrail that will be installed.

Can Shortened Blinds Be Replaced?

The manufacturer may note that any blinds altered will have their warranty voided. Check on that before proceeding with any shortening and decide if you’re okay with that.
