- First, you need to prepare a tape measure.
- Write down the width and height of the TV you measured.
- Multiply each number by 2 to get the total length of the four sides of the TV.
- Next, add up all the side lengths and divide by 12. This will give you the total length of the strip you need in feet.
32-inch TVs
For 32-inch TVs, you will typically need a 6-7-foot LED strip.
43-inch TVs
If your TV is 43 inches, you will need a strip of about 9 feet. Please note that the LED strip may not completely cover the outside edges of the TV, so you can subtract a few inches to decide how long to purchase.

A 55-inch TV will typically need an LED strip of about 12 feet.
65-inch TVs:
A 65-inch TV will typically need a 13-14-foot LED strip to cover the back of the TV.

For an 85-inch TV, you will need a strip of about 17-18 feet to ensure the best backlighting for your TV.
How to Add LED Light Strips Behind Your TV?
Before installing the LED light strips on the TV, we need to prepare all the necessary materials to ensure a smooth and successful installation. You need to prepare the following items:
- LED light strip (RGB, white light or smart, according to your choice)
- Adhesive backing (most LED light strips come with their own, but double-sided tape may be required)
- A tape measure, for measuring the area behind the TV
- Scissors, for cutting the LED light strip to the appropriate length
- Power supply (USB, battery pack or wall socket)
- Remote control or smart device, for adjusting color and brightness (if applicable)
1. Prepare the TV and clean the installation area
First, make sure the TV and installation area are safe and quiet. Before installation, you need to turn off the TV and unplug the power supply to avoid the risk of accidental electric shock during operation.
Next, clean the back of the TV thoroughly with a clean dry cloth or microfiber cloth. Dust, dirt or oil stains will affect the adhesion of the LED light strip, so it is important to ensure that the surface is smooth and clean.
2. Measure the size of the TV
Next, you need to accurately measure the size of the back of the TV to ensure that the LED light strip can cover the entire area.
In addition, you can choose the installation location of the light strip according to your personal preferences and room design. You can choose all-round lighting or only install the upper half, which is mainly based on personal preference.
3. Cut the LED light strip
Most LED light strips can be cut, and you need to cut them according to the length of the TV installation. Usually, LED light strips have circuits between each predetermined cutting point, and you can only cut the light strip at these specific points. If you cut the light strip at will, it may cause the light strip part to not work properly.
4. Install the LED light strips to the back of the TV
LED strips usually come with a strong self-adhesive backing, so make sure the surface is clean and flat before installing. Remove the sticky protective film on the back of the strip, and gently press the strip with your hands to ensure it is firmly attached to the back of the TV.
If you find that the LED strip is not sticky enough during installation, you can consider using additional double-sided tape or special adhesive clips to strengthen the fixation.
5. Connect the power supply
Depending on the voltage and wattage of the LED strip you selected, choose the right power supply. The next step is to connect it to the power supply. Many modern LED strips can be powered directly from the TV’s USB port, which is a very convenient option.
6. Test the strip effect
Once the installation is complete, plug in the power supply and turn on the TV to start testing the LED strip effect. Observe the brightness and color of the light to ensure that it can evenly illuminate the wall around the TV without too bright or too dark areas.
If your light strip comes with a remote control or supports smart control, you can adjust the color, brightness, and mode to experience different lighting effects.
Summary
Installing LED light strips behind the TV can not only effectively relieve eye fatigue but also enhance your viewing experience, while adding a sense of modern technology. With reasonable measurement and installation, you can easily create a lighting atmosphere that perfectly matches your interior decoration and personal needs.
