This will typically yield a detailed specification sheet that includes the screen size.
Measuring Your Laptop Screen Manually
If system information is unavailable or unclear, manually measuring the screen is a straightforward alternative. Laptop screens are measured diagonally from one corner of the display to the opposite corner, excluding the bezel (the plastic or metal frame around the screen).
To measure your laptop screen accurately, follow these steps:
- Use a flexible measuring tape or a ruler.
- Start from the inside edge of the bottom left corner of the visible screen.
- Extend the measuring tape diagonally to the inside edge of the top right corner.
- Record the measurement in inches or centimeters.
- Convert measurements if necessary (1 inch = 2.54 cm).
Avoid including the bezel in your measurement, as this will result in an inaccurate size. The screen size refers only to the display area where images and text appear.
Understanding Screen Size vs. Resolution
It’s important to differentiate between screen size and resolution, as they are often confused. Screen size is a physical measurement of the display area, while resolution indicates the number of pixels on the screen.
- Screen Size: Measured diagonally in inches; determines the actual physical dimensions of your laptop’s display.
- Resolution: Expressed as width x height (e.g., 1920 x 1080 pixels); affects the sharpness and clarity of images but not the physical size.
A larger screen size with a low resolution can appear less sharp, while a smaller screen with a high resolution can display more detail. Knowing your screen size helps in selecting appropriate accessories like screen protectors or laptop bags, while resolution is key for content creation or gaming performance.
Common Laptop Screen Sizes and Their Dimensions
Laptop screens come in a variety of sizes to suit different needs, ranging from ultra-portable notebooks to powerful gaming rigs. Below is a table listing common screen sizes along with their approximate width and height dimensions based on a 16:9 aspect ratio, which is the most prevalent in laptops today.
| Screen Size (Diagonal) | Width (inches) | Height (inches) | Width (cm) | Height (cm) |
|---|---|---|---|---|
| 11.6″ | 10.1″ | 5.7″ | 25.7 cm | 14.5 cm |
| 13.3″ | 11.6″ | 6.5″ | 29.5 cm | 16.5 cm |
| 14.0″ | 12.2″ | 6.9″ | 31.0 cm | 17.5 cm |
| 15.6″ | 13.6″ | 7.6″ | 34.5 cm | 19.3 cm |
| 17.3″ | 15.1″ | 8.5″ | 38.3 cm | 21.6 cm |
Knowing these dimensions can help in identifying your laptop screen size if you can only measure one dimension or want to compare sizes visually.
Additional Tools and Apps for Screen Measurement
If physical measurement is inconvenient, several software tools and mobile apps can assist in estimating your laptop screen size. These applications use various methods such as screen calibration, pixel density, and comparing known dimensions to provide an approximate size.
Some popular tools include:

Factors Affecting Screen Size Perception
The perceived size of your laptop screen can be influenced by several factors beyond the actual diagonal measurement. Understanding these can help you better assess
Measuring Your Laptop Screen Size Manually
To determine the size of your laptop screen accurately, you will need a measuring tool such as a ruler or a tape measure. The size of a laptop screen is typically measured diagonally from one corner of the display area to the opposite corner, excluding the bezel (the plastic or metal frame surrounding the screen).
Follow these steps to measure your laptop screen manually:
- Power off the laptop: This ensures you are measuring the screen frame without glare or reflections.
- Locate the screen edges: Identify the actual display area, which is the visible part of the screen excluding the bezel.
- Place the measuring tool diagonally: Start from the bottom-left corner of the visible screen and extend the ruler or tape measure to the top-right corner.
