Monitor diagonal: how to choose the right size

When you want to buy a new computer display, one of the first aspects you need to take into account is the diagonal of the monitor. Many users wonder what size is ideal for their activities. Manufacturers have standardized the diagonal in inches, a unit of measurement often used in the United States, but adopted internationally for screens.

How to measure the diagonal of the monitor?

The size of a monitor is not calculated vertically or horizontally, but diagonally, from one corner of the screen to the opposite corner. Thus, each monitor has an exact size expressed in inches, and this standard is used by all manufacturers to provide clarity to buyers.

Standard Monitor Sizes

On the market, the most common monitors have diagonals ranging from 19 to 34 inches. The right choice depends on how you use your computer:

• 19 – 24 inches: ideal for office work or everyday activities.
• 24 – 27 inches: Great for watching movies and multimedia content.
• 27 inches: recommended for gaming enthusiasts, offering clear visuals and immersive experiences.
• 28 – 34 inches: suitable for graphic design, photo-video editing and multitasking.

So, whether you need a monitor for productivity, entertainment, or gaming, there’s a suitable option.

Aspect ratio – an important detail

In addition to the diagonal, it is essential to also check the aspect ratio:

• 5:4 and 4:3 – the classic formats, less common today.
• 16:10 and 16:9 – the most popular variants, offering a balance between productivity and multimedia.
• 21:9 – Ultrawide, preferred by gamers and graphics professionals, for a panoramic perspective.

The diagonal of the monitor is chosen according to the purpose for which you will use it

Choosing the ideal monitor depends on the diagonal expressed in inches, but also on the purpose for which you will use it. For the office, a 22-inch monitor is enough, for movies or gaming you can go up to 27 inches, and for professional graphics a model over 28 inches is the best choice.

Also take into account the aspect ratio, but also the additional technologies (such as eye protection or refresh rate), which influence both the price and the quality of the experience. With the right information, you’ll be able to choose the right monitor for your needs.
