Understanding How Screen Size is Measured
Laptop screen sizes are always measured diagonally, from one corner of the active display area to the opposite corner. The measurement is typically given in inches. It’s crucial to measure only the visible display area and not include the bezel (the frame around the screen).
Steps for Manual Measurement
- Gather Your Tools: You’ll need a measuring tape (preferably flexible) or a ruler.
- Power Off Your Laptop: Turn off your laptop to clearly see the edges of the active display area.
- Measure Diagonally: Place one end of the measuring tape or ruler at one corner of the active display area and extend it diagonally to the opposite corner.
- Record the Measurement: Note down the measurement in inches. This is your laptop’s screen size.
- Verify Accuracy: To ensure accuracy, repeat the measurement a couple of times.
Dealing with Millimeters and Converting to Inches
If your measuring tape or ruler uses millimeters (mm), you’ll need to convert the measurement to inches.
- Conversion Factor: 1 inch is equal to 25.4 millimeters.
- Conversion Formula: Divide the measurement in millimeters by 25.4 to get the measurement in inches.
For example, if you measure 396 mm diagonally, the screen size in inches would be 396 / 25.4 = 15.6 inches (approximately).
Using Software and Operating System Features
Your laptop’s operating system can provide information about the display, although it might not directly show the screen size in inches. However, you can use the resolution and other display properties to infer the screen size.
Finding Display Resolution in Windows
- Access Display Settings: Right-click on the desktop and select “Display Settings.”
- Locate Resolution Information: Scroll down to the “Display resolution” section. This will show the current resolution of your screen (e.g., 1920 x 1080).

On Windows, you can access display settings by right-clicking on the desktop and selecting “Display settings.” The information shown primarily pertains to resolution and scaling, but it can give clues about the screen size.
Specifically, knowing the resolution and physically measuring the screen’s width or height allows you to calculate the screen size diagonally. While not a direct measurement, understanding the resolution (e.g., 1920×1080) and combining it with a physical measurement can give you a reasonable estimate. Consider that these system settings may not always explicitly state the screen size in inches.
What if I don’t know my laptop model number?
If you don’t know your laptop’s model number, there are several ways to find it. Look for a sticker on the bottom of the laptop; this sticker often contains the model number, serial number, and other identifying information. Alternatively, check the battery compartment; sometimes, the model number is printed on a sticker located there.
You can also find the model number through your operating system. On Windows, search for “System Information” in the Start menu. The System Information window will display details about your computer, including the manufacturer, model, and system type. On macOS, go to “About This Mac” from the Apple menu. This will provide similar information including the model.
How do I measure my laptop screen size manually?
To manually measure your laptop screen size, you’ll need a measuring tape or ruler. Open the laptop and measure the screen diagonally from one corner to the opposite corner, ensuring you only measure the visible screen area, excluding the bezel (the frame surrounding the screen).
Be precise with your measurement and note it down in inches. Remember that laptop screens are typically advertised based on their diagonal measurement. This manual method offers a straightforward way to determine the screen size if other methods aren’t readily available, but ensuring the measurement is diagonal and accurate is crucial for reliable results.
Does the bezel size affect the advertised screen size?
No, the bezel size does not affect the advertised screen size. The advertised screen size refers to the diagonal measurement of the active display area, the part of the screen that actually shows images. The bezel is the border or frame surrounding the screen, and its dimensions are not included in the screen size specification.
Manufacturers focus on the visible display area when specifying screen sizes because this is what matters to the user experience. While thinner bezels can make a laptop appear more modern and compact, they do not change the advertised screen size, which is determined solely by the diagonal measurement of the active display.
Are screen sizes always the same across different manufacturers for the same advertised size?
While laptops may be advertised as having the same screen size (e.g., 15.6 inches) across different manufacturers, there can be slight variations in the actual visible display area. These minor differences are usually within acceptable tolerances and are not significantly noticeable.
The variations can arise due to differences in manufacturing processes, panel sourcing, and bezel design. Although the advertised screen size aims to be a standardized measurement, slight discrepancies may exist in the real-world dimensions of the screen. These differences, however, are generally minimal and shouldn’t drastically affect the user experience or compatibility with accessories.
