What To Know Already?

While measuring the laptop screen, several aspects can stop you from getting the measurements right, and these arise due to a lack of knowledge and guidance or myths.

Here is some information you need to know before measuring the laptop screen (manually via tape).

  1. Display vs. Screen Area: It is important to know the difference between display and screen area. Hence, identify the display area and the visible screen without including the bezels. On the other hand, the screen area is the total area, including the visible screen and the bezels.
  2. Identify the Corners: If you’re trying to measure the screen manually, it is important to identify the bottom-left and top-right corners of the visible screen area for accurate measurement while using accurate tools.
  3. Do not include the Bezel: As the bezel part of the display doesn’t display anything and is used to align the display with the frame properly, it shouldn’t be measured.  
  4. Place your Laptop Properly: Ensure your laptop screen is in the correct orientation and is on a flat and stable surface to get accurate measurements.
  5. Avoid Parallax Errors: Always place the ruler or measuring tape perpendicular to the screen to avoid parallax errors, as it can get the measurements wrong.

These are critical factors that must be considered while measuring a laptop screen. Additional aspects like cleaning the screen before measuring, turning off the laptop, and learning to measure unconventional screen shapes make less room for mistakes.

How To Measure a Laptop Screen Running Windows

Unfortunately, Windows doesn’t allow you to find the laptop’s screen size. We have tried several 3rd party Windows profiling software, which we had no luck with.

However, a software named “Belarc Advisor” could list almost every device specification. Here are steps to find out the laptop screen size using Belarc Advisor.

  1. Begin by running Belarc Analysis as administrator to provide the software with complete access.

  1. After the software has loaded and is running, wait for the scanning process to finish.

  1. Once the scanning process has finished, the software generates a “Computer Profile Summary,” displayed on your chosen browser.
  2. After the “Computer Profile Summary” generated by Belarc is opened on the browser, scroll down until you find the section “Display” in which the display size is mentioned.

The reason for suggesting the above methods is their accuracy and less room for error, as the computer generates the results. However, if you want to measure it manually using tape, follow the next method.

How To Measure a Laptop Screen Using a Tape

Unlike the above methods, you don’t have to worry about finding options or installing 3rd party software, but you should know how to use a tape.

Here are the steps to measure a laptop screen using tape.

  1. Before the measurement, ensure your laptop is turned off and placed on a flat surface with the screen facing you.
  2. Have a flexible tape measure ready for the measurement, and we suggest starting from the bottom-left corner of the laptop screen.
  3. Now, place the zero end of the tape measure at the bottom-left corner of the screen and gently extend the tape measure until you reach the upper-right corner.
  4. Once you have reached the upper-right corner, keep the tape measure steady and note the measurement where the upper-right corner aligns with the tape, which is your laptop screen size.

We suggest taking measurements multiple times to avoid errors and for better accuracy.

How can I measure a laptop screen accurately?

Follow the step-by-step guide using a tape measure, ensuring straight alignment from bottom-left to upper-right corners.

What’s the difference between display and screen area?

The display area excludes bezels, while the screen area includes both visible and bezels.

Bezels don’t display content; they align the screen in the frame.
