You can determine the size of your external monitor by looking at its physical dimensions or its screen diagonal measurement.
Physical Dimensions
The physical dimensions of a monitor are typically measured in inches or centimeters. They represent the width and height of the monitor's screen, excluding the bezels.
Screen Diagonal Measurement
The screen diagonal measurement is the most common way to express the size of a monitor. It refers to the distance between opposite corners of the screen, measured in inches. This measurement is usually displayed prominently on the monitor's packaging and specifications.
How to Find Your Monitor Size
- Check the monitor's specifications: Most monitor manufacturers provide detailed specifications on their websites or in the user manual.
- Look at the monitor's packaging: If you still have the original packaging, the monitor's size will be listed on the box.
- Use a ruler or tape measure: Measure the diagonal distance across the screen, from one corner to the opposite corner.
Examples:
- A 27-inch monitor has a screen diagonal measurement of 27 inches.
- A 15.6-inch laptop screen has a screen diagonal measurement of 15.6 inches.
Note: The actual viewing area of a monitor may be slightly smaller than the screen diagonal measurement due to the presence of bezels.
