How to measure a TV
With a new TV it’s so easy to go for the largest one. And although bigger is better, the last thing you want is to get it home and it not look right in your space. Instead of crossing your fingers and hoping for the best, there’s a few things you can do to make sure you pick the right size for you.
Before we get into it, the basic thing you need to know is that a screen is measured diagonally from corner to corner, but this doesn’t include the size of the bezels around the edge. If you’re fitting a TV into a tight space and need to know how big these are, it’s best to look at the width too.
What Size is Right for Me?
How to measure a TV screen
Checking the size of your TV screen is really simple. All you’ve got to do is grab a tape measure and pull is across the display from the top-right to the bottom-left diagonally. That’ll give you the screen size, which is usually shown in inches.

The general rule of thumb is that if you’ve got the space, go as big as you can. Most TVs are all screen and no bezel these days, so you should at least have a few more inches to play with than your last.
You need to think about how far away the screen will be from where you’re sat. This helps you find a good size that won’t be too small, or so big that you’re constantly moving your head to keep up with the action.
Not sure what size you need? Try this general rule:
| Viewing Distance | Ideal TV Size |
| 1.2 – 1.8m | 32" – 43" |
| 1.8 – 2.4m | 43" – 55" |
| 2.4 – 3.0m | 55" – 65" |
| 3.0 – 3.6m | 65" – 75" |
| 3.6m+ | 75" and above |
For the perfect experience, you usually want the distance to be 6x the TV’s height. Higher quality screens look better the closer you are.
