Computer Monitor Size Comparison Chart: A Detailed Guide

A computer monitor is an essential piece of equipment for anyone using a computer. It allows you to see what is on the screen and interact with it.

Although most people are content with the size of their current monitor, others may be curious about the different sizes available and want to know which is best for them.

In this blog post, we will compare three different monitor sizes and help you decide which one is right for you.

When it comes to choosing a computer monitor, size matters. But just how big do you need your monitor to be?

What are the Different Types of Monitors on the Market?

Computer Monitor Size Comparison Chart

Here We will compare different sizes of computer monitors so that you can make an informed decision about which one is best for you.

We’ll look at a small monitor, a medium-sized monitor, and a large monitor and compare their dimensions, resolutions, prices, and other features.

By the end of this post, you should have a good idea about which size of a computer monitor is right for your needs.

Small monitors are typically between 17 and 20 inches in size.

They are ideal for people who don’t need a lot of screen space, such as those working on small projects or using the computer for basic tasks.

Small monitors tend to have lower resolutions than their larger counterparts, but they are still perfectly suitable for everyday use.

Additionally, small monitors are often the most affordable option and can be found for a fraction of the cost of larger monitors.

Medium-sized monitors are what most people opt for. These range in size from 21 to 24 inches, and they offer a good balance of screen space and portability.

The resolutions of medium-sized monitors are typically higher than small monitors, but not as high as large ones.

Medium-sized monitors are a good option for those who need more screen space than what a small monitor offers but don’t need all the bells and whistles of a large monitor.

Lastly, there are large monitors. These range from 25 to 30 inches in size and are the best option for those who need the most screen real estate.

These monitors have the highest resolutions and are generally the most expensive, but they are also the best choice for gamers, video editors, or anyone who needs a lot of space for their work.

No matter which size you choose, make sure to consider your budget, needs, and preferences when selecting a computer monitor.

Each size offers its own set of benefits, so make sure to choose the one that fits your needs.

How Is Monitor Size Measured?

Computer monitor size is usually measured in two ways: diagonal measurement and aspect ratio.

Diagonal measurement is the distance across a monitor’s display, from the top left corner to the bottom right corner.

This measurement is used when comparing different-sized monitors, as it gives an idea of how big a monitor is relative to other monitors.

For accurate diagonal measurements of a monitor, generally, a formula like p= (l2 + w2) is applied. In this formula, l is the length and w is the width of the monitor.

The aspect ratio is the width-height ratio of a monitor’s display.

This measurement is important for determining how large a monitor’s display is, as well as how much of a picture or video fits on the screen.

The most common aspect ratio for monitors today is 16:9, which is the same as an HDTV.

Aspect ratio is the ratio of a monitor’s width to its height and is usually expressed as x:y.

This measurement is used when comparing monitors of different shapes, as it gives an indication of how a monitor will look.

Aspect ratio, on the other hand, refers to the ratio of a monitor’s width to its height.

This is usually expressed in a fraction, such as 4:3 or 16:9. Generally speaking, wider aspect ratios (such as 16:9) are better for watching movies or playing games, while a more traditional 4:3 ratio is better for office work.

Computer Monitor Size Comparison (24 vs 27 vs 32)

However, they also require the most graphics processing power to run.

Text Scaling and OSD (On-Screen Display)

When looking at computer monitor size comparison, one of the biggest factors to consider is scaling and OSD (On-Screen Display) size.

Generally, the larger the monitor size, the bigger the scaling and OSD window can be. 24″, 27″ and 32″ monitors are the most popular sizes on the market.

A 24″ monitor offers great scaling performance with an OSD size that is comfortable to use and read.

The 27″ monitor offers a larger viewable area and more scaling performance than the 24″ model but requires a larger typeface in its OSD.

The 32″ monitor has the largest viewable area and most scaling performance but requires the largest typeface in its OSD.

When it comes to gaming, the larger size of 32″ monitors offers a more immersive experience. The scaling performance also helps with games that have lots of on-screen elements.

In terms of general productivity and multitasking, the larger size of 32″ monitors is helpful for keeping multiple windows open at once and improves the overall user experience.

The scaling performance of a 27″ monitor is still good for productivity but provides more space to work with than a 24″ monitor.

Overall, the decision of which size monitor to choose depends on what you plan to use it for. If gaming and productivity are your main focus, then a 32″ monitor is the way to go.

If you’re mainly using it for web browsing and light gaming, then a 24″ or 27″ monitor may be better suited to your needs.

No matter which size of monitor you choose, it is important to make sure that the display quality and resolution are up to par.

Look for monitors with a high refresh rate, wide viewing angles, and good color accuracy. With the right monitor, you will be sure to have an enjoyable viewing.

The Cost Comparison

When shopping for a computer monitor, another important factor to consider is cost.

While larger monitors may have more features and higher resolution capabilities, they also come with a higher price tag.

Smaller monitors may be more affordable, but lack the same level of functionality and image quality as their larger counterparts.

It is important to consider the total cost of a monitor before making a purchase.

Additionally, it may be worthwhile to invest in features such as anti-glare, adjustable stands, and upgraded ports to get the most out of your monitor.

Ultimately, it is important to decide what size and features best fit your needs and budget.

As an example, a 24-inch monitor could cost around $150 while a larger 32-inch may cost around $350.

This is a considerable price difference and should be taken into account when choosing the ideal computer monitor for you.

Furthermore, it is important to research the specs on monitors that fit into your budget to make sure you get the best quality for your money.

Things to Consider Before Buying a Monitor

When it comes to buying a computer monitor, size is certainly something you’ll want to consider. But there are other important factors as well.

Before you take the plunge and purchase a new monitor, here are some of the things to think about:

Screen Type and Resolution

Different screen types and resolutions affect the clarity and sharpness of your image, as well as its color accuracy.

When choosing a monitor, make sure to consider the type of display – such as LCD, LED, or OLED – and its resolution (1080p, 4K, 8K).

Refresh Rate and Response Time

Refresh rate and response time refer to how quickly the monitor can update its image and respond to commands.

A higher refresh rate and lower response time are ideal for gamers, while a low refresh rate is sufficient for general web browsing.

Ports and Connectivity

Make sure to check the ports and connectivity of your monitor. USB-C and HDMI connections are essential for newer computers, while a VGA connection may be necessary for older systems.

Display Panel Type

The panel type of the monitor affects its color accuracy, viewing angles, and response time.

IPS and VA panels are typically considered to be the best for color accuracy and viewing angles, while TN panels are best for response times.

The IPS vs. TN vs. VA Debate

When it comes to computer monitors, there are generally three types of display panel technologies used: IPS (In-Plane Switching), VA (Vertical Alignment), and TN (Twisted Nematic).

Each type of panel has its own strengths, weaknesses, and uses.

IPS panels offer the best color accuracy, viewing angles, and response times. However, they tend to be more expensive and have higher input lag.

VA panels offer good viewing angles and image quality but tend to lack response time and color accuracy compared to IPS panels.

TN panels have the fastest response times but the worst color accuracy and viewing angles. They are typically used for gaming due to their fast response time but are not ideal for color-critical work.

When it comes to choosing the best panel type for you, it is important to consider your needs and what you intend to do with the monitor.

If you’re primarily using it for gaming, then a TN panel may be the best choice. If you need accurate colors and good viewing angles, an IPS panel may be better.

And if you’re not sure or just want something in-between, then a VA panel will do the job.

Straight vs Curved Displays

Another important consideration when buying a monitor is whether to get a straight or curved display.

Curved displays provide an immersive viewing experience, while straight displays offer more accurate colors and viewing angles.

Which one you choose ultimately comes down to personal preference, so make sure to try out both before making a decision.

The Curved Monitors offer a more immersive viewing experience while Straight displays offer more accurate colors and better viewing angles.

Curved monitors are excellent for gaming, watching movies, or any type of media that requires more immersion.

Straight monitors are better for types of tasks where colors and accuracy of the content matter more, such as photo editing or graphic design.

Webcam and Speakers

Many monitors today come with integrated webcams and speakers, which can be convenient if you don’t want to purchase separate peripherals.

However, the quality of these features may vary depending on the model. Be sure to check reviews before purchasing a monitor with a built-in webcam and speakers.

Design and Mounting Options

The design and mounting options of a monitor are also important factors to consider.

Some monitors have adjustable stands that allow for different viewing angles, while others may come with wall-mount options.

You should also check if the monitor has any special ergonomic features, such as a height-adjustable stand, to help make it more comfortable to use.


Choosing the right computer monitor for your needs can be a daunting task.

With so many different models, specs, and features to choose from, it’s important to consider how you will be using the monitor.

Factors such as panel type, display size, design and mounting options, webcams, and speakers all need to be taken into account.

Make sure to read reviews before purchasing, and take your time to decide which monitor is right for you.

With the right knowledge, you can make an informed decision that will provide you with the monitor you need.

Happy shopping!
