The laptop screen size will be measured in inches diagonally from corner to corner.  It’s okay if you want to know how big my laptop screen size is. Measuring your laptop’s or desktop’s size is easy with tape or another method. With this helpful guide, BeingDot will show you how to do it in a way that you can understand easily. 

Here we are described simply to understand everyone, even a non-technical person who wants to know how laptop screens are measured using an inch of tape or a simple mathematical equation.

What Is The Best Way To Measure Your Laptop Screen?

What Is The Best Way To Measure Your Laptop Screen? Determining the screen size of your laptop without a measuring tape is possible by using a simple comparison method. One approach is to compare the screen size to a standardized A4 paper, which measures 13 inches diagonally. 

Determining the screen size of your laptop without a measuring tape is possible by using a simple comparison method. One approach is to compare the screen size to a standardized A4 paper, which measures 13 inches diagonally. 

By aligning the laptop screen with the paper, you can assess whether it is smaller or larger. Based on this comparison, you can estimate the screen size to be either 11.6 inches, 13.3 inches, 14.1 inches, 15.4 inches, or 17.3 inches.

This method offers a practical solution when you don’t have a measuring tape on hand and need to determine your laptop’s screen size.

How Big Is A Standard Laptop? Laptop size comparison.

Laptop screens are available in various sizes, with 13 and 15 inches being the most popular choices. 

Other standard sizes include 11.6, 14.1, 12, and 17 inches. These different sizes cater to different user preferences and needs, offering options for both portability and larger-screen real estate.

Step 1: The tape measure should be standard.

The most accurate way to measure a laptop screen is by using a standard tape measure. Typically, tape measures have inch units on one side, which is ideal for measuring screen size. However, if you only have a tape measure with a different unit, you can easily convert it to inches using online conversion tools. 

Ensuring precise measurements is important when it comes to purchasing accessories or replacing a laptop screen, so using a tape measure is the recommended method for obtaining accurate results.

Step 2: You need to find your starting point.

Before you embark on measuring your laptop screen size, there are two crucial aspects to understand. Firstly, laptop screens are always measured diagonally, from one corner to the opposite corner. 

Secondly, it’s essential to identify the correct measuring point. Contrary to what many assume, the starting point is not the top corner of the screen, but rather the point where the actual screen begins. 

To determine this, you’ll need to power on your laptop and observe where the screen starts and ends. As a recommended method, use the top left corner as the starting point and the bottom right corner as the ending point, following the diagonal line.

Step 3: Write Down Your Measurement.

After successfully measuring your computer screen size, it’s important to make a note of it to ensure you don’t forget the measurement. 

If you measured in inches, there is no need for any conversion. However, if you used a different unit of measurement, it’s advisable to convert it to inches. 

This is necessary because the screen industry follows the standard of labeling screen sizes in inches, whether it’s a laptop screen, desktop computer screen, or even a television. 

By converting the measurement to inches, you can easily compare and understand the screen size to industry standards and specifications.

Step 4: Converting Centimeters To Inc.

Converting your laptop screen size from centimetres too inches is a simple process. Since 1 inch is equivalent to 2.54 CM, you can divide the measured size by 2.54 to obtain the corresponding size in inches. 

For example, if you measured your screen to be 34 CM, it would convert to approximately 13.3 inches.

How to Find Laptop Screen Size in Windows 10?

Finding the laptop screen size in Windows 10 is a simple process that can be done through the Display settings. Here’s how you can do it.

  1. Right-click on the desktop and select “Display settings” from the context menu.
  2. In the Display settings window, scroll down to the “Scale and Layout” section.
  3. Under the “Display resolution” subsection, you will find the screen resolution mentioned in pixels (e.g., 1920 x 1080).
  4. Below the resolution, you will see the “Display size” option with a slider. Adjust the slider to your desired size, and the screen size in inches will be displayed next to it.

Remove the screen and check the user guide

An alternative method to determine the size of your laptop screen accurately is by removing it and locating the model number sticker on the back. Most laptop model numbers include the screen’s physical size in inches. 

For example, in a model number like “LMM1568891,” the first three digits after the letters indicate the screen size, which is 15.6 inches diagonally in this case. 

Sometimes, the laptop or product box may have a sticker with the screen size, or you can find it in the user manual. 

Note, however, that there may be instances where the screen size is incorrect, causing inconvenience. Therefore, physically measuring the laptop screen whenever possible is the most reliable approach.

Perfect for informed buyers.

When purchasing a new laptop, one of the crucial factors to consider is the screen size. However, understanding how laptop screens are measured can be a bit confusing.

Understanding Screen Size:

Laptop screens are measured diagonally from corner to corner, usually in inches. This measurement provides you with an indication of the screen’s physical size. It’s important to note that the screen size does not include the bezels surrounding the display.

Aspect Ratio:

Aspect ratio refers to the proportional relationship between the width and height of the screen. It determines the shape and dimensions of the display.

The two most common aspect ratios for laptops are 16:9 and 16:10. A 16:9 aspect ratio is wider, providing a better viewing experience for multimedia content, while a 16:10 aspect ratio offers more vertical space, ideal for productivity tasks.


Resolution determines the number of pixels on the screen, which directly affects the clarity and sharpness of the displayed content. Common laptop screen resolutions include Full HD (1920 x 1080 pixels), QHD (2560 x 1440 pixels), and UHD or 4K (3840 x 2160 pixels).

Higher resolutions generally offer crisper visuals, but they may also impact battery life and require more powerful hardware.

Display Technology:

Laptop screens utilize various display technologies, each with its characteristics. The most prevalent technologies are.

LCD (Liquid Crystal Display): This is the most common display technology, known for its balance between cost, image quality, and power consumption.

IPS (In-Plane Switching): IPS panels provide wider viewing angles and better colour accuracy compared to standard LCD screens. They are suitable for tasks that require colour precision, such as graphic design or photo editing.

OLED (Organic Light-Emitting Diode): OLED displays offer deep blacks, vibrant colours, and excellent contrast. They are typically found in premium laptops and provide an immersive visual experience.

TN (Twisted Nematic): TN panels are affordable and offer fast response times, making them suitable for gaming. However, they generally have narrower viewing angles and less accurate colour reproduction.


Understanding how laptop screens are measured is crucial for choosing the right size. Diagonal measurement using a tape measure accurately determines the screen size. If a tape measure is unavailable, comparing it to a standard A4 paper provides an estimation. 

Online searches, user manuals, and manufacturer websites offer detailed specifications. Knowing how screens are measured empowers informed decision-making, enabling you to find the perfect laptop screen size.
