About this calculator
This calculator helps you determine the ideal height for mounting your TV on the wall. The center of the screen is set at 1.10 meters from the floor, the average eye level of a seated person. You enter the TV height in centimeters, and the tool calculates the distance from the floor to the top of the TV. This value serves as a reference for attaching the bracket, ensuring a comfortable viewing experience without straining your neck.
The calculation is simple: the TV center is fixed at 1.10 m. The distance from the floor to the top of the TV equals the center plus half the TV height. For example, if the TV is 80 cm tall, the top is at 1.10 m + 0.40 m = 1.50 m from the floor. This method considers only the center height, ignoring the base or bracket. Adjustments may be needed depending on sofa height, posture, or personal preference.
Use this calculator when planning to install a TV in a living room, bedroom, or home theater. It is useful for those who want to avoid neck pain or eye strain caused by a screen that is too high or too low. It also serves as a starting point for professional installers or for those renovating a room. Remember to measure the actual TV height, including the frame if any.
Important considerations: the 1.10 m height is an average and may vary with user height and furniture type. Lower or higher sofas require adjustments. Also, consider the bracket tilt: if it is articulated, the height may differ. Always check the distance from the eyes to the center of the screen, which should be 2 to 3 times the TV diagonal for visual comfort.
Frequently asked questions
Why should the center of the TV be at 1.10 m from the floor?
This is the average eye level of a person sitting on a standard sofa. Placing the screen center at this height prevents you from tilting your head up or down, reducing the risk of neck pain.
My TV is 65 inches. What is the top height?
First, convert inches to centimeters (1 inch = 2.54 cm) and measure the actual height of the TV. Then use the formula: top = 110 cm + (TV height in cm / 2). For example, a 65-inch TV is about 81 cm tall, so the top is at 110 + 40.5 = 150.5 cm from the floor.
What if I watch TV lying down on the sofa?
If you are reclined, your eye level changes. In that case, it may be better to position the center a little lower, between 100 and 105 cm, to maintain visual comfort.
Do I need to consider the bracket size?
Yes, the calculator gives the height of the TV top, not the bracket. The bracket is usually a few centimeters above the top. Measure the distance between the bracket holes and the top of the TV to adjust the wall fixing position.
What is the ideal distance between the TV and the sofa?
A distance of 2 to 3 times the screen diagonal is recommended. For example, for a 55-inch TV (140 cm), sit between 2.8 and 4.2 meters away. This avoids eye strain and allows you to see the entire screen without moving your head.
