When it comes to purchasing a laptop, one of the most critical factors to consider is the screen size. A laptop’s screen size can significantly affect how well it meets your needs in terms of performance, usability, and portability. This article will provide you with the essential information you need to understand laptop screen sizes and factors to consider in choosing the right one for your needs.

Understanding laptop screen size terminology

A. Diagonal screen measurement
B. Resolution
C. Aspect ratio

Before diving into the details of measuring and choosing the right laptop screen size, it is essential to understand the terminology associated with screen sizes.

Diagonal screen measurement

Laptop screen sizes are generally measured diagonally, from one corner of the screen to the opposite corner. This measurement is expressed in inches and serves as the primary means of comparing screen sizes across different models.


Screen resolution refers to the number of pixels displayed on the screen. The higher the resolution, the more details and sharper the image will be. However, high-resolution screens can make text and icons appear smaller, so you should consider this when choosing a laptop screen size.

Aspect ratio

The aspect ratio is the relationship between the width and height of the screen. The most common aspect ratio for laptops is 16:9, which provides a widescreen format suitable for watching movies and playing games. Other aspect ratios, such as 16:10 or 3:2, may offer more vertical screen space for tasks like document editing or web browsing.

How to measure screen size

A. Using a measuring tape
1. Measuring the screen diagonally
2. Avoiding confusion with measurement units
B. Using built-in system information
1. Finding screen size on Windows
2. Finding screen size on macOS
C. Checking laptop manufacturer’s specifications

Using a measuring tape

To measure your laptop’s screen size using a measuring tape, follow these steps:

  1. Ensure the laptop is turned off and the screen is clean.
  2. Place the end of the measuring tape at one corner of the screen (inside the bezel) and measure diagonally to the opposite corner, excluding any part of the bezel or case.
  3. Take note of the measurement in inches, rounding up to the nearest inch if necessary. This is your laptop’s screen size.

Avoiding confusion with measurement units: Remember that laptop screen sizes are measured in inches, not centimeters.

Using built-in system information

You can check the screen size of your laptop using built-in system information on your device.

For Windows:

  1. Right-click on the desktop and choose Display settings.
  2. Scroll down to the Scale and layout section.
  3. Under Resolution, find the screen resolution in pixels (e.g., 1920×1080).
  4. Search online for the screen size in inches associated with that resolution for a general estimation.

For macOS:

  1. Click on the Apple logo in the top left corner and choose About This Mac.
  2. Click on the Displays tab.
  3. Look for the screen’s resolution in pixels (e.g., 2560×1600) and search online for the screen size in inches associated with that resolution for a general estimation.

Checking laptop manufacturer’s specifications

To find your laptop screen size without measuring it, you can check the manufacturer’s specifications and documentation, usually available online or in the user manual. Look for the model number or serial number on the laptop’s bottom to find the exact model you have.

Factors to consider when choosing a laptop screen size

A. Intended usage (e.g. gaming, video editing, browsing)
B. Portability and weight
C. Screen resolution and quality
D. Budget

The selection of your laptop screen size should be based on your specific needs and preferences. The following factors should be considered:

Intended usage

Consider the tasks you’ll be using your laptop for the most. If you require a larger screen for tasks like gaming, video editing, or graphic design, consider medium to large screens. On the other hand, if you mainly use your laptop for web browsing, document editing, or light workloads, a small to medium screen size may suffice.

Portability and weight

The larger the screen, the bulkier and heavier the laptop generally is. If you need a laptop that is easy to carry around, especially for travel or daily commutes, a smaller screen size would be a better choice.

Screen resolution and quality

Higher resolution screens provide more details and sharper images, but they can also make text and icons appear smaller. If you need high-resolution screens for tasks like photo editing, consider larger screen sizes to accommodate the higher resolution without compromising usability.


Laptop screen sizes can significantly affect the price of a laptop. Generally, larger screens are more expensive, so it’s crucial to consider your budget and the balance of the features you need when selecting a screen size.
