Measuring Your Laptop Screen Manually
To accurately determine the screen size of your laptop, you can measure it manually using a ruler or a tape measure. The screen size is measured diagonally from one corner of the display to the opposite corner, excluding the bezel (the frame surrounding the screen). This measurement is typically expressed in inches.
Follow these steps for a precise measurement:
- Ensure your laptop is powered off and on a flat surface.
- Use a ruler or tape measure that can measure inches or centimeters.
- Place the ruler at the top left corner of the visible screen (not the frame).
- Extend the ruler diagonally to the bottom right corner of the visible screen.
- Note the measurement and convert centimeters to inches if necessary (1 inch = 2.54 cm).
This method is effective when you do not have access to system information or specifications.
Using System Information to Identify Screen Size
Many laptops provide built-in software tools that display hardware specifications, including the screen size. This method is quick and requires no physical measurement.
- On Windows laptops, open the “Settings” app, go to “System,” then “Display.” Here, you might find screen resolution, which indirectly helps infer screen size.
- For more direct information, use the “System Information” tool (type “msinfo32” in the Run dialog). However, screen size may not be explicitly listed.
- MacBooks display screen size in the “About This Mac” section under the Apple menu, showing the display name and size.
- On Linux, commands like `xrandr` can provide screen resolution details, which can be correlated with known laptop models.
While resolution is not the same as physical size, knowing the model number combined with resolution can help you look up the exact screen size online.
Finding Screen Size Through Laptop Model Number
If you know your laptop’s model number, you can easily find its screen size by searching the specifications online. Manufacturers list detailed specs, including screen size, on their official websites.
To find your model number:
- Look for a sticker on the bottom of the laptop or beneath the battery compartment.
- Alternatively, check system information on Windows by typing “System Information” and locating “System Model.”
- On MacBooks, click the Apple menu and select “About This Mac” to see the model identifier.
Once you have the model number, visit the manufacturer’s website or trusted review sites, then:

Understanding Screen Size vs. Screen Resolution
It is important to distinguish between screen size and screen resolution, as they are related but different aspects of a laptop display.
- Screen Size refers to the physical dimension of the display, measured diagonally in inches.
- Screen Resolution refers to the number of pixels displayed on the screen, usually expressed as width × height (e.g., 1920×1080).
A larger screen size does not always mean higher resolution; some large screens may have low resolution, and smaller screens can have high resolution. This affects image clarity and workspace area.
| Aspect | Definition | Typical Measurement | Impact on User Experience |
|---|---|---|---|
| Screen Size | Physical diagonal measurement of the display | 11″ to 17″ inches (common laptop sizes) | Determines portability and workspace |
| Screen Resolution | Number of pixels horizontally × vertically | 1366×768 to 3840×2160 pixels | Determines image sharpness and detail |
Understanding both metrics helps in selecting a laptop that fits your needs, whether for portability, media consumption, or professional work.
Using Third-Party Software Tools
Several third-party applications can assist in identifying your laptop’s screen size and related display characteristics. These tools often provide detailed hardware diagnostics beyond basic system information.
Popular tools include:
- Speccy: Provides comprehensive details about your system, including display size and resolution.
- HWMonitor: Focuses on hardware monitoring but may include display information.
- AIDA64: Offers in-depth hardware and software analysis, including screen specifications.
Using these tools:
- Download and install from the official websites.
- Run the software and navigate to the display or monitor section.
- Look for physical screen size or model number, which can help confirm screen dimensions.
These tools are especially helpful if manual measurement or model lookup is inconvenient or unavailable.
Measuring Your Laptop Screen Size Manually
To determine the screen size of a laptop manually, you need to measure the diagonal length of the visible display area. This measurement is expressed in inches and represents the distance from one corner of the screen to the opposite corner.
Follow these steps to measure accurately:
- Turn off the laptop: This prevents reflections and makes the screen edges clearer.
- Use a ruler or tape measure: Preferably a flexible tape measure for better handling.
- Measure from corner to corner diagonally: Start from the inside edge of the bottom-left corner of the screen (not the bezel), and measure to the inside edge of the top-right corner.
- Avoid including the bezel: The screen size only includes the viewable display area, not the surrounding frame or casing.
| Measurement Location | Purpose | Notes |
|---|---|---|
| Inside bottom-left screen corner | Start point for diagonal measurement | Do not include bezel or frame |
| Inside top-right screen corner | End point for diagonal measurement | Ensures measurement covers visible display only |
If the measurement falls between standard sizes, round to the nearest common laptop screen size (e.g., 13.3″, 14″, 15.6″). This manual method provides a reliable estimate when device specifications are unavailable.
