For instance, accurately calibrated tension guarantees a seamless raising and lowering experience, enabling precise control over light and privacy levels within your home or office.

But why do we need to adjust tension in cordless blinds?

  • To improve or ensure smooth operation-proper or adequate tension on the cordless blinds ensures smooth operation, guaranteeing that the blinds can glide smoothly. Hence, you can effortlessly control the light and privacy of your space.
  • To inhibit snapping or sagging– You can prevent sagging or snapping of your cordless blinds through optimal tensioning. Often, sagging compromises the appearance of your window blinds, influencing their aesthetics. You do not want an untidy look in your room or office space when your window treatment snaps or sag. Adjusting the tension helps correct the problem and improve their functionality, which can be influenced over time.
  • To improve safety– well-maintained tension also translates to the general safety of your cordless blinds. If you have small children or pets in your home or around your office, one of the reasons you want to choose cordless blinds is to guarantee their safety from dangling cords. Proper tension helps prevent sudden drops or erratic movements.

As a result, tensioning ensures that your window treatments can serve you for an extended period before you replace them. In other words, you get the value of your money.

How to Adjust Tension on Cordless Blinds

The process of tension adjustment might vary based on the type and brand of your cordless blinds.

Follow the below process

Step 1: Identify the Tension Mechanism

Locate the tension adjustment mechanism on your cordless blinds. In most cordless blind types, the mechanism is situated near the top of the blinds and often positioned on the side for easy access.

Step 2: Gather Necessary Tools

Depending on the type of tension adjustment mechanism, you might require basic tools such as a flat-head screwdriver or an Allen wrench.

Step 3: Adjusting the Tension

Tightening Tension: Tighten the tension by inserting an appropriate tool, such as a screwdriver or Allen wrench into the tension adjustment point. Turn the tool clockwise to increase the tension and test the blinds after adjustment to determine whether it can raise and lower efficiently. This will confirm the smooth operation.

Loosening Tension: Like tightening, you need to insert the screwdriver into the tension adjustment point or mechanism and turn the screw counterclockwise to reduce the tension. Once you have reduced the tension to a given level, test the movement of the blinds to ensure they are not excessively loose and are moving smoothly.

The above process will either reduce or increase the tension on the cordless blinds to ensure effective and smooth operations of your window treatment.


NOTE: Adjusting tension on the cordless blinds can vary depending on the type of window treatment you have. The above process is standard for the majority of cordless blinds.

However, other types of cordless blinds like cordless Roman blinds and cordless cellular shades can be adjusted as follows:

A. Cordless Roman Blinds

Among the various types of cordless blinds, cordless Roman blinds may be the easiest to use. However, just like their counterparts, cordless Roman blinds are bound to exhibit complications at times. Adjusting the tension on cordless Roman blinds entails:

  • Rotating the blind’s tube. Cordless Roman blinds are fitted with a tube on the upper side, which goes a long way when adjusting the tension. Firmly grab the tube using your hand and rotate it halfway in an upward direction, then let it go, and voila!


  • Push the blind forward and tug it. This method should be your go-to if the blind is not too stuck. Push it a few inches forward, then yank it up into position, and you’re good to go.

The mode of operation of cordless cellular blinds is almost similar to the other types of cordless blinds. The process of adjusting the tension on cordless cellular blinds is practically identical to that of cordless Roman blinds and is as follows:

  • Pull down the blind. For this first step, ensure you gently pull down the blind to avoid tampering with its cords.
  • Pull the blind a few inches from the wall. Ensure the blind forms a forty-five-degree angle with the wall.
  • Tug the blind firmly but gently to restore its position. You may repeat the process several times for the best results.

C. Cordless Faux Wood Blinds

The popularity of cordless faux wood blinds could be attributed to their moisture-resistant nature, which enhances durability. For this reason, these are the most preferred cordless blinds for bathrooms. To adjust the tension on cordless faux wood blinds;

  • Locate the screw on the headrail. Most cordless faux wood blinds feature an adjusting screw on the headrail, which comes into play whenever you need to adjust the tension.
  • Adjust the screw using a screwdriver. To loosen the tension, rotate the screw in an anti-clockwise direction utilizing a screwdriver. If the blind sags, you may want to tighten the tension by rotating the screw in a clockwise direction until you achieve your preferred level of tension.
