To measure a laptop computer screen, you determine its size by measuring the diagonal distance across the screen.
The Standard Method
The standard way to measure a laptop screen size is by taking a tape measure or ruler and measuring the distance from one corner of the display area diagonally to the opposite corner.
It is crucial to ensure that you are measuring the actual screen area itself. This means you should not include the surrounding bezel or frame that borders the screen. The measurement obtained, typically given in inches, represents the advertised screen size of your laptop.
Step-by-Step Measurement
Here is a simple guide to measuring your laptop screen:
- Gather your tool: Get a flexible tape measure or a stiff ruler.
- Position the tool: Place the beginning of your tape measure or ruler precisely at one corner of the illuminated screen area.
- Measure diagonally: Extend the tool across the screen to the opposite corner.
- Focus on the screen: Ensure your measurement spans only the visible, active part of the screen, excluding the plastic or metal border (bezel) around it.
- Note the size: Read the measurement where the tool meets the opposite corner of the screen. This measurement, taken in inches, is your laptop's screen size.
For example, if the diagonal measurement from the bottom-left corner of the actual display area to the top-right corner is 15.6 inches, your laptop has a 15.6-inch screen.
Using this diagonal measurement is the industry-standard method for specifying screen dimensions, making it easy to compare different devices.
