How to Measure Computer Monitor Sizes - Detailed Buying Guide

|Nov 30, 2022

You can utilize a computer for work or play games on it. You might as well use it to watch your favorite shows on your HBO account, YouTube, or even Netflix. Therefore, choosing a model that works for both you and your requirements is essential because, in the end, it will remain your computer monitor.

Purchasing a new pixel monitor is difficult with several standard computer monitor sizes, regardless of whether your old screen has gone dead or you've just decided to update the most recent applications. However, not everybody has the same aspirations. While some customers' priorities feature accessibility, others are more concerned with a stunning and appropriately sized display.

Considering that the market is full of several different computer monitor sizes. It's simple to become confused when so many excellent selections are available, so we have created a helpful shopping guide for you.

How to Properly Measure Computer Monitor Sizes

The average computer monitor size can be defined as a diagonal distance between one upper corner and its corresponding bottom edge. When calculating the size of a monitor, the display borders aren't considered. In contrast to display resolution, assessed in pixels, the display size is stated in inches. The simplest approach to determine the size of your screens would be to look that up in the handbook.

You could even put the brand of your gadget into Google and retrieve the equipment's exact specifications along with other computer monitor sizes comparisons. Another easy method of determining a display's size is also available if all other methods are unsuccessful. This technique calls for the use of a measuring tape or meter ruler. Using this technique, you measure the screen in a diagonal direction from the upper right side toward the bottom left edge or the opposite.

The dimension of your screen would depend on the diagonal distance between the top left corner, the bottom right, and perhaps the other way around. The display itself shouldn't be measured; the borders or enclosures spread across the display should be considered. There is an additional approach that uses a little bit of math. We can also apply the Pythagorean Theorem throughout this approach.

According to its principle, the diagonal dimension is determined by adding the cubes of the perpendicular angle and the base, which together make up a right-angled pyramid, to get the squared digits of the display size. Take the display's width and length measurements (while leaving the borders out, of course), then use the Pythagorean Theorem by adding all squares of the display's horizontal and vertical directions.

The result of your square root calculation would be the real measurement of your ergonomic monitor height. You can also use this method to calculate large computer monitor sizes. Furthermore, you may buy one of the best displays from the Pixio store.

Interpreting Monitor Size Specifications

Decoding monitor size descriptions (e.g., 24", 27", 32", etc.)

When shopping for monitors, you'll often come across specifications that describe the size of the display. These descriptions typically include a number followed by an inch symbol (") such as 24", 27", or 32". This number represents the diagonal size of the monitor in inches. For example, a 24" monitor has a diagonal measurement of 24 inches from one corner of the screen to the opposite corner.

Considering aspect ratio and screen resolution

It's important to note that the diagonal size alone does not provide a complete understanding of the monitor's dimensions or its visual real estate. Two monitors with the same diagonal size may have different aspect ratios and screen resolutions, resulting in variations in the physical height and width of the display.

Aspect ratio refers to the proportional relationship between the width and height of the screen. Common aspect ratios for monitors include 16:9, 16:10, and 4:3. A 16:9 aspect ratio means that for every 16 units of width, there are 9 units of height. Monitors with a 16:9 aspect ratio are widespread and suitable for most applications, including multimedia and gaming.

Screen resolution refers to the number of pixels displayed on the screen horizontally and vertically. Higher resolutions generally offer sharper and more detailed images. The resolution is usually specified in terms of the number of pixels horizontally by the number of pixels vertically, such as 1920x1080 (commonly known as 1080p) or 2560x1440 (referred to as 1440p or Quad HD).

Comparing monitor sizes for different applications (gaming, productivity, etc.)

When choosing a monitor size, it's essential to consider the intended use and the distance at which you'll be viewing the screen. Different applications have varying requirements for optimal viewing experiences.

For gaming or immersive multimedia experiences, larger monitors with wider aspect ratios, such as ultrawide displays, can enhance the field of view and provide a more immersive experience. These monitors often range from 29" to 49" or even larger.

For productivity and multitasking, larger monitors offer more screen real estate, allowing you to have multiple windows and applications open simultaneously. Monitors in the 27" to 34" range are popular choices for productivity-focused setups.

If you have limited desk space or prefer a more compact setup, smaller monitors in the 22" to 24" range may be suitable. These sizes are commonly used for basic tasks such as web browsing, document editing, or as secondary monitors in multi-monitor setups.

Remember that personal preferences and usage scenarios can vary, so it's crucial to consider factors such as viewing distance, desk space, and your specific needs when selecting a monitor size.

Understanding monitor size specifications and considering factors such as aspect ratio, screen resolution, and intended use will help you make an informed decision when choosing the right monitor size for your needs. Take the time to compare different options and consider your specific requirements to find a monitor that offers the best visual experience and meets your preferences.

Everything Else You Should Know Before Buying a Monitor

Computer displays are frequently the most overlooked. A bad choice might reduce productivity and perhaps injure your spine and vision given how long the average consumer stares at a computer screen. An excellent display frequently makes sense when most of your job depends only on the interaction between your vision and your display.

Investing in a big enough display to read comfortably is worth it. Therefore, when you are on a quest to purchase a new monitor, keep the following features in mind:

Screen Resolution

The amount of pixels a screen needs to show a picture is known as resolution. Display resolutions generally comprise two numbers. 1920 x 1080 represents the most popular resolution that is offered. This seems equivalent to 1920 x 1080 with horizontal and vertical pixels. Additionally, larger resolutions appear much clearer and let you see more data on the panel. It's important to note that every element on display grows shorter as the higher the display's resolution goes. With a few tweaks, Microsoft does a worthwhile job of resizing those components.

Video Sources or Inputs

Monitor connection types that are often used are VGA, HDMI, as well as Display-Port. Generally speaking, it's a smart option to match your desktop's connection, even if you connect the MacBook to the monitor. Display-Port is often the best option because it enables 4K at 3840 x 2160 with sixty frames per second. With readily available connections and the capacity to transport acoustic signals, HDMI is a viable alternative. DVI-D, however, may support greater resolutions, while DVI normally only supports 1920 x 1200. Given that it is an analog transmission, the outdated VGA should be utilized as a final option. VGA links' sharpness is often inferior to that of the other interfaces.

Video Sources or Inputs


When buying a monitor, like with other parts and materials for computers, you get out what you invest. Approximately $150 will get you a 24 inches basic 1920 x 1080 processor with few features. But on the other hand, a high-end 4K display that is 32 inches or bigger and has an ergonomic design can easily be worth $500 or more. The cost of a display often increases with larger panels and better resolutions.

If your desktop can accommodate vertical monitors, you can choose a dual display system if you require additional room but don't want a gigantic screen. Default by most computers often supports a multi-display arrangement (at least 2 screens). This is an excellent technique to increase your usable space by double.

Generally, two somewhat less expensive monitors are more cost-effective than one enormous, high-quality panel. The appropriate display may simplify your job by giving you more workspace and reducing eye strain.



Question: What do I need to know before purchasing a monitor?

Answer: The optimal display should have a minimum refresh rate of 75 Hz and the quickest available reaction time. For this reason, gamer screens have a dynamic refresh rate of over 120 Hz (the fastest available is 360 Hz), so you should look for a higher reaction time of 5 ms. Refresh rate is very crucial for gaming enthusiasts.

Question: Is playing games on a curved monitor vs. a flat better?

Answer: Curved gaming displays provide a more immersive and interactive experience than flat panels. They achieve this by extending the viewing area of the display's sides.
