How Do I Find My Laptop’s Screen Size on Windows 11?

Method 1: Using System Settings

Open Settings: Click on the Windows icon in the taskbar or press the Windows key on your keyboard, then select the “Settings” app (it looks like a gear).
Navigate to System: In the Settings window, click on “System” in the left-hand menu.
Select Display: In the System settings, click on “Display”.
Find Display Resolution: Scroll down to the “Display resolution” section. The first number in the resolution (e.g., 1920 x 1080) relates to the width and height of your screen in pixels, but doesn’t directly tell you the physical screen size.
Check Advanced Display Settings: Click on “Advanced display” to find more detailed information.
Identify Display Information: Here, you might find the monitor model number. You can then search the model number online to find the official screen size specification.

Method 2: Using Manufacturer’s Website

Find Your Laptop’s Model Number: This is usually located on a sticker on the bottom of your laptop, under the battery, or in the original packaging.
Visit the Manufacturer’s Website: Go to the official website of your laptop’s manufacturer (e.g., Dell, HP, Lenovo, Asus).
Search for Your Model: Use the search bar on the manufacturer’s website to find your specific laptop model.
Locate Specifications: Once you find your model, look for the “Specifications” or “Tech Specs” section.
Find Display Information: In the specifications, you should find the screen size listed in inches (e.g., 15.6 inches).

Method 3: Using DirectX Diagnostic Tool

Open the DirectX Diagnostic Tool: Press the Windows key, type “dxdiag,” and press Enter.
Check System Information: The DirectX Diagnostic Tool window will open.
Examine Display Tab: Click on the “Display” tab.
Note Monitor Information: Look for the “Monitor” section. While it may not directly display the screen size, it often shows the monitor name or model. Use this information to search online for the screen size specifications.

Method 4: Measuring the Screen Manually (If All Else Fails)

Prepare Tools: Grab a measuring tape or ruler.
Measure Diagonally: Measure the screen diagonally from one corner to the opposite corner, excluding the bezel (the plastic frame around the screen).
Record Measurement: Note the measurement in inches. This is your screen size.

Tips For Accurate Screen Size Detection

Double-Check: If possible, cross-reference the information from multiple methods to ensure accuracy.
Consider Bezel Size: Remember that the screen size refers to the viewable area, not the entire laptop lid.
Use Official Sources: The manufacturer’s website is the most reliable source of information.
