A Guide to Understanding How Screen Sizes Are Measured for Laptops


Buying a laptop can be an intimidating process due to the wide array of choices available. One of the most important features to consider when shopping for a laptop is the size of the display. Laptop screens are measured diagonally to determine their size, in contrast to television screens which are measured horizontally and vertically. This guide will explain how laptops screens are measured, examine the common laptop screen sizes, and discuss the pros and cons of larger displays.

When choosing the screen size for a laptop computer, there is a guideline to follow. Screens are measured diagonally from one corner of the display to the opposite corner. This measurement gives a good indication of the size of the entire display and its overall viewing area. Common laptop display sizes range from 10.1-inches to 17.3-inches, with 15.6-inches being the most common.

Inches Versus Pixels

Are you having trouble understanding the difference between inches and pixels when it comes to measuring laptop screens? You’re not alone – a lot of people struggle to make sense of how laptop screens are measured.

First, it’s important to understand the basics. A laptop screen’s size is typically measured diagonally from corner to corner, in terms of inches. So, for example, a 17-inch laptop screen has a diagonal of about 17 inches.

However, measuring laptop screens in inches alone doesn’t tell us the full picture. Instead, when it comes to screen resolution, pixels become the key measurement. For example, a laptop screen with 1920 x 1080 pixels will have a higher resolution than one with 1366 x 768.

The main differences between pixels and inches is that pixels are a measure of energy, while inches are a measure of physical size. Pixels are simply the individual dots of light that make up an image on your laptop screen, while inches refer to how physically big, or small, the measurements of the laptop screen are.

So, when it comes to buying a laptop, the inches refer to your laptop’s overall physical size, while the pixels refer to the resolution and amount of detail you can expect. Armed with this knowledge, you should now be a bit more informed when making your decision.

Aspect Ratio: Length to Width

Do you want to purchase or upgrade your laptop but don’t know which size is right for you? Knowing the aspect ratio of a laptop is key to finding one that fits your needs. It’s a simple yet important factor that affects your laptop performance in a big way.

What Is the Aspect Ratio?

Aspect ratio is the ratio between the length and width of a laptop’s display. Generally speaking, a laptop’s aspect ratio will be a number that is either close to 16:9 (13.3″, 14″, 15.6″ displays), 3:2 (12″ displays), or 5:4 (17″ displays).

How Do You Measure the Aspect Ratio?

To measure the aspect ratio of a laptop, simply measure the width and the length of the screen. Divide the width by the length and that will give you the aspect ratio of the laptop you are considering.

How Can the Aspect Ratio Affect Your Laptop Experience?

The laptop’s aspect ratio determines what resolution it can run, which in turn affects your gaming, streaming, and movie-watching experience. A higher aspect ratio (closer to 16:9) results in larger resolutions and pixel densities. This means more efficient multitasking and clearer image quality.


By understanding the aspect ratio of a laptop, you can determine the resolution and size you need. Aspect ratio is an important factor to consider when looking for a laptop and definitely something to keep in mind when shopping around.

Understanding how laptop screen sizes are measured is important if you want to buy the best possible model. Here’s a guide to help you find the perfect laptop screen size for you!

Measuring the Screen of Your Laptop

When purchasing a laptop, one of the features you’ll want to consider is the screen size. Screen size affects portability, battery life, and cost, so it’s important to find the laptop with the perfect size for you.

The size of a laptop screen is measured diagonally from corner to corner. That means, for example, a 15-inch laptop has a 15-inch screen although its width and height can be different. The actual display width and height is sometimes measured in centimeters rather than inches.

When comparing laptop screens, the resolution is another important factor to consider. The higher the resolution, the more detailed the display will be. If you plan to watch videos or work on graphics-intensive tasks, a higher resolution will be beneficial.

Finally, don’t forget to look at the aspect ratio. The aspect ratio defines the ratio between the width and height of a display. Older laptop displays usually have a resolution of 4:3, which means the width and height are equal, while modern displays are usually 16:9, which is great for watching films.

With this guide, you’re well-prepared to understand how screen sizes are measured when buying a laptop. Choose the right screen size and resolution to make sure you find the right laptop for your needs.


In conclusion, understanding how laptop screen sizes are measured is an important factor when choosing the right laptop for your needs. Knowing the measurements will help ensure that you get the size of the laptop that provides the optimal viewing experience. Additionally, the type of resolution plays a significant role in providing a quality viewing experience. Being aware of the size, type and resolution options, as well as the different types of laptops available will help you find the perfect laptop for your needs.
