Know about Laptop Screen Dimensions?
Before we measure laptop screen, first take a look at screen dimensions. Laptop screens come in a variety of sizes, with the most common ones being 13.3 inches, 14 inches, 15.6 inches, and 17.3 inches.
These sizes refer to the diagonal measurement of the screen, which is the distance from the top left corner of the screen to the bottom right corner.
The screen dimensions in terms of width and height will depend on the aspect ratio of the display. The most common aspect ratio for laptop screens is 16:9, which means that the width of the screen is approximately 1.78 times its height.
For example, a 15.6-inch laptop with a 16:9 aspect ratio will have a screen width of about 13.7 inches and a height of about 7.7 inches.
Some laptop screens have an aspect ratio of 3:2, which is more square-shaped. These screens are typically found on laptops with high-resolution displays and are more suited for tasks such as photo and video editing.

13.3 inches | 33.8 cm |
14 inches | 35.6 cm |
15.6 inches | 39.6 cm |
17.3 inches | 43.9 cm |
Keep in mind that these sizes refer to the diagonal measurement of the screen, which is the distance from the top left corner of the screen to the bottom right corner. The actual width and height of the screen will depend on the aspect ratio of the display.
Laptop screen size with Recommended resolution
Here is a table that shows the size of common laptop screen sizes along with recommended resolutions for each size:
Laptop screen size (inches) | Recommended resolution |
13.3 inches | 1366×768 (HD) |

15.6 inches | 1920×1080 (Full HD) |
17.3 inches | 1920×1080 (Full HD) |
Keep in mind that these recommendations are based on the assumption that you want a high-resolution display that is suitable for tasks such as watching movies and TV shows, playing games, and editing photos and videos.
If you are using your laptop mainly for web browsing, word processing, and other basic tasks, you may not need a display with such a high resolution. In that case, you could consider a lower resolution, such as 1366×768, which is more budget-friendly and may result in longer battery life.
