How to Measure a Television Screen

By Megan Smith

If you're looking to sell your old television, you'll need to determine what size it is before placing it up for sale. Wide-screen and standard televisions can have the same measurements without being the same size. For example, a 32-inch standard television has an aspect ratio of 4:3, while a 32-inch wide-screen television has an aspect ratio of 16:9. Therefore, it 's important to measure your TV with the correct measuring process before selling it, regardless of whether you have a wide-screen or a standard model.

Step 1

Place the metal part of a measuring tape in the lower left corner of your television screen. Hold it in place with your finger.

Step 2

Stretch the measuring tape across to the upper right corner of the television screen. The measuring tape should stretch diagonally across the television.

Step 3

Write down the measurement.

Step 4

Take note of whether the television is wide-screen or standard. If the television is wide-screen, it will be wider and not as tall as a standard TV. Therefore, a 32-inch wide-screen TV will seem much larger (because it's wider) than a 32-inch standard television.

Step 5

Measure the width and height of your screen. If you're selling your TV, your buyer may not know the size discrepancy between 32-inch wide-screen televisions and 32-inch standard televisions. Have this information readily available and explain that television sizes are always measured diagonally.
