All TVs come in different sizes and dimensions. If you’re looking to buy a TV, this is one of the most important factors to consider.
People who don’t pay attention to this crucial aspect often have buyer’s remorse because the TV they buy is either too small or too big in relation to the room size.
To avoid this, it’s essential to know how sizes and dimensions work in the smart TV world. Knowing the available sizes and corresponding TV dimensions, the size of your room, viewing distance, stand requirements, and more will help you make the best choice.
This post will explore the various TV sizes and dimensions for some of the famous brands you know. We also discuss how to measure TVs and what size would fit your room size.
How Are TVs Measured?
TVs are measured by the diagonal size of their screen, from corner to corner. This measurement is done from the visible parts of the screen only.
Which TV Size Should I Get?
The optimal screen size depends on the size of your room. As you read further, you will find recommendations you could use. Ideally, for a small size room, you should go for something around 32 inches.
TV Dimensions by Size and Brand – Manufacturers’ Measurements
IMPORTANT: These are the manufacturers’ dimensions and they have different arrangements.
TVs are typically measured by Height, Width and Depth. The width is typically the largest number, followed by the height and the depth is the smallest number.
Width: Use a tape to measure horizontally from side to side to find the width
Height: Measure the tv from top to bottom to get the height
Depth: Measure the TV from the front to back to find the depth. You can do this with or without the tv stand.
TV Screen: This is the advertised size and is measured diagonally from one end of the screen to the other NOT including the tv bezel or plastic casing.

Where Should I Place My TV?
If you have bought any of these TVs already, the following guide will help you choose a suitable position for it.
Take the diagonal measurement of your TV to figure out where you should put it. Multiply by 1.5 to get the total. This is the least distance you should sit from your television.
That’s 112.56 inches or 9.38 feet for a 75-inch TV. You should, however, consider this distance a range.
If you have a 1080p TV, you should sit between 9.38 and 15.63 feet away from it. If you have a 4K television, you can get closer to the screen without the image becoming blurry. You can view a 4K TV from a distance of 6.25 to 9.38 ft.
