To measure a TV screen, the most common and accurate method is to measure the diagonal length of the screen. This is done using a tape measure or ruler and involves measuring from one corner of the visible screen to the opposite corner diagonally. This diagonal measurement is expressed in inches and represents the screen size advertised for TVs.
Steps to Measure a TV Screen:
- Use a tape measure or ruler.
- Measure diagonally from one upper corner of the visible screen (not including the bezel or frame) to the opposite lower corner.
- Record the measurement in inches; this is the size of the TV screen.
- Optionally, measure the width (left edge to right edge) and height (top edge to bottom edge) of the visible screen for additional dimensions.
Additional Tips:
- The diagonal measurement usually does not include the outer frame or bezel of the TV.
- Measuring the full unit including the bezel can be useful for space planning or considering wall mounts.
- Most modern TVs have a standard 16:9 aspect ratio, so the width and height relate proportionally to the diagonal size.
This method ensures that the screen size is correct for purchase decisions, fitting spaces, and understanding viewing distance requirements.
