How are laptop screens measured?

How are laptop screens measured? This is easy. There are several easy ways to find your laptop’s screen size. These are discussed in more detail in this article.
Laptop screens vary in size and proportion. The laptop screen was marked as the essential feature as it was the first feature that attracted all customers to buy it. So screen size is also important. In addition, the larger the screen, the higher the cost of the brand’s model.

The general concept for measuring laptop screen size:

A common concept for measuring laptop screens is to measure diagonally. The most accurate method is to measure diagonally from the upper left corner of the laptop screen to the lower right corner. This includes only the measurements of the screen.
Some people mistakenly measure the outline of the frame, but the size of laptop screen size is where Windows is displayed. Laptop screen sizes are typically measured in inches.

Measuring tape usage:

The size of the laptop screen can be easily found by measuring the screen with a tape measure. When measuring the screen, make sure the tape measure calibration surface is on the opposite corner of your laptop. Also, as a precaution, the screen can get dirty, so make sure the tape is clean.

Reviewing the laptop manual:

Open the laptop manual and search for display properties to see the dimensions measured using the tape measure. The guide contains the correct dimensions for your laptop screen.

Viewing the back of the laptop:

Turn your laptop over and look for a label with the laptop model and some key laptop specifications. The size of the screen is also included.
Other than that, on some laptops, the screen size is numbered in the upper right corner. For example, H243HX means the screen size is 24 inches.

Visiting laptop website:

You can easily find your laptop screen size by browsing the web and visiting the official website of your laptop brand with the exact model number. By doing this, you will have an idea of what size your laptop screen is.

If your laptop has a raised slope surrounding the screen, don’t include it in your measurements. Diagonal measurements on laptop screens typically range from 11 to 17 inches. When you have a diagonal measurement, convert it to tenth inches (for example, convert 15 inches and 1/2 inch to 15.5). 17 inch laptops delivers most amazing experience.

Online Screen Measurement:

Google search can display websites that say the screen size is determined remotely. Some of these can provide the full diagonal length of the screen, mainly if a calibration method is provided. However, you can get more accurate results with a physical ruler.

Model Specifications for Laptops:

Another way to find the answer to “ How are laptop screens measured” your laptop size online is to search for model specifications. Many manufacturers post screen sizes for their laptop models on their websites. The manufacturer’s website also explains how to identify the model depending on the manufacturer, so if you don’t know the name and model of your laptop, you can find it.

Display Size vs. Resolution:

Laptop resolution differs from screen size. Resolution refers to the number of pixels, the small squares that make up a screen. Laptop screens can be set to different resolutions regardless of the physical size of the screen. The most common resolutions are 1366 x 768 and 1920 x 1080. The first number is the number of pixels on the entire screen, and the second number is the number of pixels decreasing.

How to measure a laptop Dimensions Correctly?

There are many reasons why you should know the exact dimensions of your laptop. Measuring screen size alone is not enough. Here’s how to measure a laptop screen correctly:

Depth measurement:

Then measure the laptop across a short surface area. To measure, hold the tape measure under the hinged cover and slide the tape measure upwards. If your laptop base is more profound than the display hinges, be sure to include this area in your measurements. It has depth.

Width measurement:

The second step in measuring laptop dimensions is measuring the width. It is easier than measuring screen size as it doesn’t need to be measured horizontally, and there is no frame to exclude. With the laptop closed, run the measuring tape from left to right along the longest edge to read the reading or width.

Height measurement:

Measuring the height and thickness of a laptop can be the easiest part. This is mainly because it’s the smallest part of a laptop we’ve measured. Place the laptop on a flat, level surface. Start the measuring tape from the laptop’s bottom, the flat surface on which the laptop sits, run the measuring tape vertically on top of the laptop, lift it vertically, and then read. Now you know the dimensions of your laptop.

Additional Aspects to Consider on determining “How are laptop screens measured.”

You should also consider some other factors besides the screen’s size.

Contrast Ratio:

Another thing to look at is the contrast ratio of the screen. The contrast ratio is the difference in brightness between the brightest and darkest colors. A display with a high contrast ratio is often converted to a display with a more accurate color rendition.

Dimensions of the screen:

Screen resolution is a term used to describe the number of pixels packed in an area of the screen. Most laptops have 1920 x 1080 resolution, but a cheaper option would decide 1024 x 720. To understand the terms more naturally, most manufacturers use them as FHD (Full High Definition), 1440, 4k, etc.,, the abbreviated as.
The general idea of screen resolution is that the higher the value, the more precise the screen. This requires getting a laptop with a higher screen resolution to immerse yourself in a more detailed, vibrant, and bright display. Some laptops have 4k resolution. However, these laptops come at a high price. Still, the 1080p screen resolution is sufficient for most laptop tasks, even for graphics-intensive tasks


Brightness is probably one of the most important considerations for consumers around the world. Like smartphones and mobile devices, our laptops need to provide a bright screen that accurately displays the screen despite harsh lighting.
Mesh is a unit used to measure the degree of brightness from the screen. In general, a laptop with a high nits rating means a bright screen. Most laptops these days range from 200 to 300 mesh. If the computer exceeds 300 nits, this is very good compared to the average rating. Macs are generally better at providing bright screens. Recent versions have screens that can reach up to 540 mesh.

Color Accuracy:

Another measure of screen quality is how you can view the black level. This aspect is somewhat similar to the contrast ratio. However, this is more about determining how the screen can show black. This is measured numerically. The smaller the number, the better the black level representation. This means that you can display a pitch-black color on the screen.
Apart from this, the level of white is also measured. In contrast, higher values mean more efficient white representation. A value of 255 is the maximum level detected on the RGB scale. At this level, the screen can display a more accurate white color.

Refresh rate:

There are some aspects to consider, such as sRGB graphics and HDR. However, it only highlights the importance of knowing the screen refresh rate. Refresh rate is a term used to describe the frequency of a screen changing an image. When measured in Hertz, laptops have average refresh rates of 60 Hz and 144 Hz. This is very important for consumers who are interested in games.
The higher the refresh rate, the better the game and fewer crashes. That way, you don’t have to worry about constant lags or lags when your graphics card is at its best, especially for graphics-intensive games and tasks.

FAQs: How are laptop screens measured?

If you're debating which dimensions to choose for your laptop, it might just be a more complex question for your taste. The choice depends on your lifestyle and experience, as laptops are extremely useful and offer an increasingly complex set of features. HP laptops vary in size like other manufacturers, but you can easily filter your laptop search by screen size.

Larger screens are generally more productive and immersive, but smaller models are often better suited for commuters and those who work on the go. Whatever size you choose, focus on comfort and use.

A laptop's screen size or overall physical configuration does not have universal standards, but some parts are more similar than others. For example, larger screen sizes are unlikely to hurt portability, as more manufacturers prioritize thin builds less than an inch thin.

On the other hand, screen sizes are somewhat more consistent, and most laptops have 15 to 17-inch screens. Compact laptops range from 11 inches to 14 inches. However, the size of the screen still needs attention. Just because the diagonal measurements on the two screens are the same, the vertical and horizontal measurements are the same.

With all the screen size measurements, you may be wondering what the most common sizes are for laptop screens. The most common sizes include:

11.6 inches

12.1 inches

13.3 inches

14 inches

15 inches

15.6 inches

17 inches

As a general guide, laptop screens start at around 11 inches on the smallest edge and go up to about 17 inches on the widest edge. Therefore, there are quite a few options here. When buying a new laptop, first decide on the screen size you need. You will pay more for the larger screen.

Yes, you can, but the ruler is not flexible, making it a more difficult task. Also, remember that most notebooks have rounded edges, which you can quickly compensate for with a tape measure, not a straight ruler.

Of course, if you don't have access to a tape measure, the next best thing is to use a ruler. However, it should be noted that the measurements you take are less likely to be accurate than a tape measure.

I have no idea why. However, many laptop users believe that the screen size specified in the specification is wide. I don't know who started the rumors, but it's not. You can use two laptops with the same screen size but completely different widths.

Good examples are Lenovo ThinkPad and Macbook Pro. Both models have a screen size of 13.3 inches. However, the Lenovo is 12.28 inches wide, and the Macbook is 11.97 inches wide.

Screen size refers to the diagonal length from the top corner on one side of the screen to the bottom corner on the other, excluding the bezel. The bezel is the bezel surrounding the display and does not count as part of the display for obvious reasons.

Small-screen laptops are generally light and compact. You can find a model that offers excellent resolution but does not improve the viewing angle. Instead, get a device with an extensive physical profile of the trimmer. This can also reduce the weight by a few pounds.

A small screen is an excellent choice if your priority is to work comfortably in any environment, such as an airplane seat or a crowded cafe. But it's not just weight you want to remember. This is because smaller screens usually consume less power than more extensive options.

The laptop has a smaller bezel that keeps the dimensions larger while retaining the larger screen.

Frames are not counted when measuring the size of the laptop screen. That's why I think the 13-inch MacBook from five years ago was much larger than the current MacBook. That's also why Dell XPS laptops with "Infinity Edge Display" come in either 13 inches or 15 inches but are significantly smaller than their competitors.

In response to the question, yes. The laptop screen is measured diagonally. This is because the laptop is rectangular instead of square. It is very inconvenient for frames to enter and view content at the same time.

Almost any modern screen you have will be rectangular. The era of Square 4:3 screens is over. Initially, all laptops, monitors, and TVs had an aspect ratio of 4:3, which facilitated the square shape.

However, if you switch to a 16:9 display or later to a 16:10 display, all laptop screens will be rectangular. This supports both productivity and multitasking.
