Is 4K necessarily better?
When it comes to computer monitors, this may not always be the case. Several factors must be taken into account when selecting your monitor’s size, such as the required screen space and your comfort during usage. An excessively large or small screen can lead to issues like eye strain and other forms of discomfort.
What’s the Ideal Size for a 4K Monitor?
When determining the best size for a 4K monitor, factors like its resolution, pixel density (PPI), and viewing comfort must be taken into account.
1. Resolution
For monitors with resolutions of 1920×1080 pixels or 1920×1200 pixels, the ideal screen size is between 23 to 24 inches. Larger monitors with these resolutions tend to display images with poor quality, often appearing pixelated or lacking smoothness.
Ultrawide monitors with a resolution of 2560 x 1080 pixels are best suited for sizes ranging from 25 to 29 inches. This provides users with a wider horizontal workspace while maintaining clean and clear image quality.
4K monitors are available in various sizes, from 22 to 43 inches. It is generally recommended to opt for a 4K monitor that is 27 inches or larger to fully appreciate the higher resolution.
2. Pixel Density
Pixel density, or the number of pixels per square inch (PPI), significantly impacts the viewing experience. Higher PPI results in better image quality, while larger screens with fewer pixels may display pixelated images when zoomed in or out. Here are the recommended pixel densities based on your 4K monitor size:
- 183 PPI for a 24-inch monitor
- 163 PPI for a 27-inch monitor
- 138 PPI for a 32-inch monitor
- 110 PPI for a 40-inch monitor
3. Viewing Comfort
User comfort is a crucial factor in determining the ideal 4K monitor size. Some individuals find 24 inches sufficient for their needs without straining their necks or eyes. On the other hand, gamers often prefer larger screens to expand their field of view and enhance immersion.
However, using a large screen at a short viewing distance can strain the eyes and lead to headaches. The recommended guideline is to maintain a distance of one arm’s length between your eyes and the monitor. For screens up to 27 inches, this distance is suitable. If you’ll be positioned more than five feet away from the screen, consider choosing a monitor larger than 27 inches.
Ultimately, monitor size preferences vary from person to person. Visiting a computer store and testing different sizes based on your intended viewing distance is the best way to determine which size suits your needs best.
The ideal size of 4K monitor for offices
In an office environment, the ideal 4K monitor size typically falls within the range of 24 to 27 inches. These monitors provide good screen space for tasks like document viewing, graphic design, and multitasking.
For instance, the LG 24-inch UltraFine monitor offers a 4K UHD IPS display with a 178º viewing angle both horizontally and vertically. It boasts a 60Hz refresh rate and a 14ms response time, making it suitable for various office tasks.

The ideal size of a 4K gaming monitor
When it comes to gaming, the best 4K monitor size can vary based on individual preferences. While some gamers may find 24-inch 4K monitors sufficient, others prefer larger screens to fully immerse themselves in games and appreciate finer details.
Some gamers recommend opting for a 27 or 28-inch 4K monitor for the best gaming experience. This size offers a generous play area while still being manageable, especially if you’re considering a dual or multiple monitor setup for a comprehensive gaming experience.
An example of a popular 4K gaming monitor is the BenQ EL2870U, which features a 28-inch 4K display, catering to gamers who value both visual quality and immersive gameplay.
