How To Find Out Your Laptop Screen Size Without Measuring [4 Methods]

If you want to buy a new laptop, replace your old screen, or get a screen protector, you might need to know the size of your laptop screen. However, measuring it with a ruler or a tape can be tricky and inaccurate. Fortunately, there are other ways of How To Find Out Your Laptop Screen Size Without Measuring physically. In this article, we will show you four simple methods to do that.

Key Takeaways

• You can find out your laptop screen size by checking the model specifications, the user manual, the system information, or the display settings.
• The screen size is usually measured diagonally in inches, excluding the bezel or the frame around the screen.
• The screen resolution is the number of pixels that make up the screen, and it can affect the quality and clarity of the display.
• The screen aspect ratio is the ratio of the width to the height of the screen, and it can affect the shape and layout of the display.

Method 1: Check the Model Specifications

The easiest way to find out your laptop screen size is to check the model specifications of your laptop. You can find them on the packaging box, the user manual, or a sticker on the bottom of your laptop. The model specifications should include the screen size in inches, along with other information such as the processor, memory, storage, and battery.

If you don’t have access to these sources, you can also search for your laptop model online and look for the official website or a reliable review site that provides the screen size. To find your laptop model, you can use one of these methods:

• Open Run by pressing Win + R. Type msinfo32 and press Enter to open System Information. Check the Value of the System Model¹.
• Open Start and type dxdiag in the search box. Press Enter to open DirectX Diagnostic Tool. Check the System Model under System Information².
• Open Start and type cmd in the search box. Press Enter to open Command Prompt. Type wmic csproduct get name and press Enter. Check the Name value³.

Method 2: Check the Display Settings

Another way to find out your laptop screen size is to check the display settings on your laptop. You can access them by following these steps:

• Open Start and select Settings > System > Display.
• Look at the Rearrange your displays section and select the display you want to check.
• Scroll down to Scale and layout and find Display resolution. This is the number of pixels that make up your screen horizontally and vertically⁴.
• Use an online calculator⁵ or a formula⁶ to convert the display resolution into screen size.

The formula is:

Screen size (inches) = √ (Horizontal pixels^2 + Vertical pixels^2) / DPI

where DPI is dots per inch, which is usually 96 for Windows laptops.

For example, if your display resolution is 1920 x 1080 pixels, then your screen size is:

Screen size (inches) = √ (1920^2 + 1080^2) / 96 = √ (3686400 + 1166400) / 96 = √ (4852800) / 96 = 2200 / 96 = 22.9 inches

Note that this method may not be very accurate, as it depends on the DPI value of your laptop, which may vary depending on the manufacturer and model.

Method 3: Use a Measuring App

If you have a smartphone or a tablet, you can also use a measuring app to find out your laptop screen size without measuring it physically. There are many apps available for both iOS and Android devices that use augmented reality (AR) technology to measure objects using your camera. Some examples are:

• Measure (iOS)
• AR Ruler (Android)
• AirMeasure (iOS and Android)

To use these apps, you need to follow these steps:

• Download and install the app on your device.
• Launch the app and grant permission to access your camera.
• Point your camera at your laptop screen and align it with the edges of the screen.
• Tap on the screen to mark the corners of the screen.
• Read the measurement result on your device.

Note that this method may not be very precise, as it depends on the quality of your camera and the accuracy of the app.

Method 4: Measure Physically

If none of the above methods work for you, you can always resort to measuring your laptop screen physically with a ruler or a tape. However, you need to be careful and follow these tips:

• Measure only the visible area of the screen, not including the bezel or the frame around it.
• Measure diagonally from one corner to another, either from top-left to bottom-right or from top-right to bottom-left.
• Measure in inches, as most laptop screens are measured in this unit.
• Round up to the nearest standard size, such as 11.6, 12, 13.3, 14, 15.6, or 17 inches.

How can you determine the screen height and width of a device using Flutter?

According to a Stack Overflow post, you can determine the screen height and width of a device using Flutter by using the following code:

double width = MediaQuery.of(context).size.width;

double height = MediaQuery.of(context).size.height;

This will give you the height and width of the device’s screen in logical pixels
