How Do You Measure a Flat Screen TV?

Measuring a TV screen isn’t as hard a task as it may seem. Whether you want to know if you’ll be able to enjoy your favorite movie or action games on your new TV, or you want to know if the TV you want to get will fit in your designated TV space, we can help you figure how exactly you’re going to measure it.

Moreover, knowing the size of your current TV can also help you compare it to the TV that caught your eye in the advertisement. Especially because sometimes the advertised size of a screen can differ from the actual size.

Thus, we’ve decided to take your TV viewing experience up a notch by ensuring you get the perfect one that is neither too big nor too small. So, before you head out with some big bucks to get your dream TV, we’ll help you measure your current one to know what exactly is the size you should get. Before we go on, here are a few important measurements you need to know:

Measurements You Need to Know

Diagonal Screen Size

First, you need to know the diagonal size as the size of a TV screen is usually measured diagonally. It is the distance between two opposite corners. We recommend measuring it in inches.

Bezel Dimensions

Next up, you’ll also want to know the dimensions of the bezel of your TV. To put it in simple words, the bezel includes all the parts at the front of your TV, excluding the screen.


After you know the bezel dimensions, you’ll also need to measure the space where you usually keep your current TV or where you’ll be keeping your new one.

How Do You Measure a Flat Screen TV?

Now that you know all the basic measurements that you’ll need to have an idea about, it’s time to get into detail so that you can measure your flat-screen TV.

Step 1: Measuring the Diagonal Screen Size

It is the simplest way to measure the screen size of a flat-screen TV. Mostly in advertisements, this is measured in inches. So, we suggest you do the same. As we mentioned above, the diagonal measurement of a TV screen is the measurement you’ll take from the bottom left of the screen to the top right or from the top left to the bottom right using the end of your tape. This measurement from one opposite corner of the screen to the other opposite corner will give you the standard screen size that companies and manufacturers use on advertisements.

However, keep in mind that it’s a well-known fact that the diagonal screen size claimed in advertisements sometimes differs from the actual size. For example, often, the advertised diagonal screen size could be 65. But the actual viewable size would be 64.5. It may not seem like a significant difference, but it does make a slight one.


When you measure the screen diagonally, make sure you only measure the screen and not the bezel or the frame on the edges.

Step 2: Measure the TV frame and Bezel

Knowing these details will go a long way, especially if you’re looking to get a new TV. It will help you know if the TV you wish to get will fit into a designated space. For this, you’ll have to measure the frames on the outer edges of the TV, the bezel, and the stand. These parts don’t change the overall size of the TV by a huge difference. Usually, just an inch or two is added; however, depending on the stand type, it can add some depth. This is why it can be important for you to know the whole TV’s size and not merely the screen.

These are important measurements to know. So, make sure you check out the TV frame size and bezel on the TV box or take a measuring tape with you whenever you head out to get a new TV and take these measurements on the spot.

Step 3: Measuring the Space Where You’ll be Keeping Your TV

For this, you’ll need to measure the area you’ll be keeping your TV, whether it’s a TV stand or a cabinet. You need to know the width, height, and depth. You could also note down these measurements and take them with you when you go shopping for a new TV.

To be on the safe side, it’s recommended to leave some room in the display safe. So, try that the stand or the cabinet you’ll be keeping your new TV in is half your hand’s width larger than the new TV is going to be. Doing that will also ease up the process of setting up a TV. Moreover, it’s also important to make sure that the new TV will offer a clear view at the place you’ll be sitting to watch your TV. To make sure you’ll be getting a good view while playing your favorite games or watching your favorite movies, you could multiply by the distance the sitting area (from where you watch TV) to the TV stand by 84%. That will give you a reliable estimate and help you get a better idea.

The ideal distance to keep between the sitting area and your TV depends on your TV’s size. The ideal distances you should keep in mind are the following:

  • For a 60″ TV – you should sit between 7.5 and 12.5 ft. away from the screen.
  • For a 65″ TV – you should sit between 8 and 13.5 ft. away from the screen.
  • For a 70″ TV – you should sit between 9 and 14.5 ft. away from the screen.
  • For a 75″ TV – you should choose between 9.5 and 15.5 ft. away from the screen.


It’s highly important to know the TV’s size and space where you keep your TV before purchasing a new one. It’s extremely simple and can be done quickly if you follow all the steps we’ve mentioned carefully. Happy shopping!
