How To Measure Laptop Screen Size? [Tips & Tricks]

The laptop screen size is one of the essential considerations in choosing a new laptop. Larger screens are typically better for viewing photos, videos, and other content. But more oversized also means heavier, so be sure to consider your needs before deciding on size. The following information will help you understand how to measure laptop screen sizes.

How to measure laptop screen size: Step By Step Guide

There are a few simple steps to measure laptop screen size.

1. Find the Diagonal Measurement

The first step in measuring a laptop screen is finding the display’s diagonal measurement. There are several ways of doing this. The most accurate measurement of a laptop screen size can be made using a ruler or cloth tape measure, but it’s more common to use an online guide such as this one. Most web-based guides include pixel and inch measurements for each screen size listed.

2. Find the Resolution or Pixel Size

Pixel size is another essential factor in determining how big your new laptop will be. Pixel size decides by multiplying the number of pixels on each horizontal and vertical axis (for example, 1920 x 1050) by two (1920 + 1050). If you find that your desired laptop screen size has insufficient pixel numbers, you may need to opt for a higher resolution.

3. Optionally, look up the Screen Density (Pixels Per Inch)

Most modern laptops will have anywhere between 96 and 220 pixels per inch (PPI), although some popular models only feature around 100 PPI. If you want to be able to cram more content on your new laptop’s screen without scrolling or zooming out, it’s best to go with a model with a slightly lower than average density (under 100 PPI). But if you want sharp images and text that are easy to read at small font sizes, choose a high-density option in the upper 90s or over 200 PPI.

4. Compare diagonal measurements to find the best size

Now that you have the diagonal measurement and the resolution or pixel size, it’s time to compare different laptop screen sizes to see which one is right for you. Be sure to consider your personal preferences when making your decision; a 14-inch laptop may be too small for some, while others might find a 17-inch model too large.

As you can see, measuring laptop screen sizes is not difficult but is essential to select the best option for your needs. By finding the diagonal measurement, resolution, and pixel density of your desired screen size, you can easily compare models and make an informed purchase.

What’s the best laptop screen size for me?

This is a question that only you can answer. Consider what you will use your laptop for, as well as how much you’re willing to carry around. If you need a large screen for watching movies and TV shows, go for a 17-inch or larger model. But if you often plan to bring your laptop with you, a smaller size like 14 inches may be more appropriate. Just be sure to measure the screen dimensions before making your final decision!

When measuring the diagonal size of a laptop screen, it’s essential to use an online guide rather than just relying on measurements in inches. This is because laptop screens can come in various aspect ratios (ratios of width to height), which can affect the inch measurements. But online guides, such as the one linked above, will list pixel and inch measurements for each screen size.

Laptop screen sizes explained. 

Below is a list of the most common laptop screen sizes and their corresponding diagonal measurements.

  • 11 inches –
  • 12.5 inches –
  • 13.3 inches –
  • 14 inches –
  • 15.6 inches –
  • 17.3 inches –

The above are just some of the most common laptop screen sizes on the market. If you don’t see your desired size, be sure to measure it yourself or use an online guide like the one linked above to get an accurate measurement. And don’t forget to take into account resolution and pixel density when making your decision!

Now that you know how to measure laptop screen sizes, you can confidently shop for your new device, knowing that you’re getting the best possible size for your needs.

The importance of a good viewing angle on your laptop screen

If you’re shopping for a laptop screen, you might be surprised to find that some models have an IPS display, while others only offer TN. To make things more complicated, not all IPS displays are created equal! There’s a stark difference in the viewing angles of different screens. For this reason, it’s essential to know what makes a sound or lousy viewing angle on a laptop screen.

IPS vs. TN: What is the best option?

IPS stands for In-plane Switching and is a feature that allows your laptop screen to show consistent colors no matter where you’re looking from. This means that whether you’re looking at your laptop from above or below or from the side, colors will remain the same. This is in contrast to TN (Twisted Nematic), a less expensive display type that often has worse viewing angles.

Screen viewing angles – What to look for

When looking at a laptop screen in a store, it’s crucial to consider the viewing angles. Some screens will have very narrow angles, while others will be more forgiving. If you plan on using your laptop in a variety of different positions, it’s best to go for a model with wide viewing angles. Otherwise, you may find yourself struggling to see what’s on the screen if you’re not sitting in the optimal position.

The bottom line

A good viewing angle is essential for anyone who wants a versatile laptop screen. TN displays often offer a lower price, but if you plan on using your laptop in a variety of different positions, it’s best to go for an IPS screen. This is because the viewing angles of TN displays are often more limited, and colors can appear inconsistent when looking from certain positions.

Understanding resolutions and pixels per inch (PPI)

When it comes to laptop screens, the resolution is king. This is because a higher resolution will mean that you can see more on the screen without scrolling. For this reason, it’s essential to be aware of the different solutions available before making your purchase.

What is a good laptop resolution?

A good laptop resolution will depend on your needs and plan to use your device. If you’re primarily using your laptop for browsing the web and checking emails, then a resolution of 1366×768 should suffice. But if you’re looking for something that offers more screen real estate, then a 1920×1080 or higher resolution may be a better option.

How do I know how many pixels per inch my laptop

You may see pixel and resolution measurements when looking at a laptop screen. But what do these terms mean? A higher number for both of these measurements indicates a better image quality. For example, a 1366 x 768 resolution is more desirable than 800 x 600 because it has more pixels spread out over the same area. And a 1366 x 768-pixel display will provide a much crisper image than an 800 x 600-pixel display!

The importance of PPI – What does this mean?

But why is it that two displays with different resolutions can have the same or similar pixel density? This is because while some screens use square pixels, others use non-square pixels. In other words, while some displays pack in more information in each square inch, others use a higher resolution but with fewer total pixels. For this reason, it’s essential to pay attention to the PPI (pixels per inch) rating when looking at different laptop screens.

PPI is often an excellent way to compare two similar screens and see which one has the better image quality. This number can help you determine whether or not you need a higher resolution for your needs.

So, now that you understand viewing angles, resolutions, and PPI, you’re ready to go out and find the best laptop screen for your needs! Just keep these things in mind, and you’ll make an informed decision.


A good laptop screen will allow you to view from various angles and positions. It’s also important to pay attention to resolutions and PPI when comparing two similar screens – this model will usually have the better image quality. You may find more than a few different screen measurements and terms, which can make it difficult for first-time buyers to pick out the best device, but as long as you know what to look for, you’ll be able to choose an excellent laptop screen!
