Measure Screen Diagonally
Measure your laptop screen from one corner to the opposite corner diagonally. This diagonal length gives you the screen size in inches. Use a ruler or tape measure for an accurate result.
Prepare Measuring Tools
Use a ruler or a tape measure for accuracy. Make sure the tool is straight and not bent. Clear the screen from dust or dirt. This helps in measuring the visible area correctly.
Measure From Corner To Corner
Place the ruler or tape at one corner of the screen. Stretch it diagonally to the opposite corner. Measure only the visible screen area, not the frame.
Avoid Including Bezels
Bezels are the black or colored borders around the screen. Do not include them in your measurement. Measure only the display part that shows images or videos.
Use System Settings
Open the system settings on your laptop. Find the Display Settingsoption. This section shows details about your screen.
Look for the Screen Resolution. It is usually shown as width x height in pixels, like 1920 x 1080. This tells you how many pixels your screen has.
You can estimate the screen sizeusing the resolution. Higher resolution often means a larger or sharper screen. But pixels do not always equal size.
Use this simple table to estimate size from resolution:
| Screen Resolution | Approximate Screen Size |
|---|---|
| 1366 x 768 | 11 to 14 inches |
| 1920 x 1080 | 13 to 17 inches |
| 2560 x 1440 | 15 to 17 inches |
| 3840 x 2160 | 15 to 17 inches or more |
For exact size, measure the screen diagonally with a ruler or tape. The number you get in inches is the screen size.
