How to Check a Laptop Screen Size

One of the factors buyers should consider when buying a laptop is the size of the laptop's screen. Electronic stores and other stores that sell laptops list a size for the available laptops in advertisements and listings. You may want to double-check the listed laptop screen size if you believe the actual size of the screen is smaller than the listed size. Knowing the exact size of a laptop screen is also important if you plan to transport the laptop in a bag or other carrier.

  1. 1

    Place the end of the measuring tape at one corner of the laptop screen.

  2. 2

    Hold the end of the measuring tape in the corner of the screen.

  3. 3

    Stretch the other end of the measuring tape diagonally to the opposite corner of the laptop screen. For example, if you started measuring in the bottom-left corner of the screen, stretch the measuring tape to the top-right corner of the screen.

  4. 4

    Read the measurement marking on the tape that is closest to the second corner (the top-right corner in the example mentioned in Step 3) of the screen. This is the correct size of the laptop screen.

Tips and warnings

  • Remember to only measure the laptop screen and not the border or casing that surrounds the screen. The laptop border/casing does not determine the size of the actual laptop screen size.
  • Be gentle when pressing the measuring tape along the laptop screen to avoid damaging the screen.
