How to figure out the shape of the monitor you need

Once you’ve decided on the size of your monitor, the next thing to consider is shape. Do you want a wide screen or a square monitor? Again, this decision comes down to personal preference and what fits best in the space where you’ll be placing the monitor. That said, some people find that wide screens are better for multitasking because they allow you to have multiple windows open side by side without overlap.

Common computer monitor sizes

When it comes to choosing a computer monitor, size does matter. A bigger screen can make a big difference in productivity, whether you’re working on graphics-heavy projects or simply want more room to spread out your work. But with so many size options available, how do you know which one is right for you?

Here’s a look at some of the most common screen sizes for computer monitors, from small to large:

17 inches

This is the smallest standard screen size for a desktop monitor ( and usually best for a second screen or backup). If you’re looking for portability or want to save desk space, a 17-inch monitor may be a good option. But keep in mind that with how things are trending this screen size as your main monitor might get tiring real fast.

19-21 inches

This is a good size for general use and web browsing. If you’re not doing anything too intensive, this size will suffice. However, if you’re looking to do any sort of graphic design or video editing, you’ll want to go with a larger size.

22-24 inches

This is a good middle-of-the-road option. It’s large enough for most tasks but not so large that it becomes unwieldy. This is a good option to consider if you’re looking for a versatile all-purpose monitor.

25 inches and up

Once you reach the 25-inch range and beyond, you’re in what’s known as “super widescreen” territory. These monitors are great for gaming, watching movies, and working with multiple programs side-by-side. However, they can be cumbersome to use if you’re not used to working with such a large display.

Do you need a secondary monitor?

Finally, if you’re looking for a second monitor, then it’s important to consider both size and shape. A good rule of thumb is to get a second monitor that’s about half the size of your primary one. For example, if your primary monitor is 24 inches, a good choice for a second monitor would be 22 inches. As far as shape goes, it’s generally best to match the shape of your primary monitor so that everything looks cohesive.

What’s the Best Resolution?

We’ve already done a full article on what screen resolution is and what it means for your computer monitor, but we thought we’d throw this section in just in case you didn’t get a chance to read that article.

Once you’ve figured out the size you’re looking for you’ll need to decide on a resolution. Resolution is measured in pixels and refers to how many pixels are displayed on your screen. The higher the resolution, the sharper and clearer your image will be. Most monitors have a resolution of at least 1280×720 (720p), but if you want HD-quality images, look for a resolution of 1920×1080 (1080p). 4K monitors are also becoming increasingly popular—they have a resolution of 3840×2160 (4K UHD)—but they can be expensive. For most people, 1080p is more than sufficient.


Choosing the right computer monitor size is important if you want to be productive, efficient, and comfortable while working at your desk. 19-21 inches is good for general use, 22-24 inches is versatile, and 25 inches and up is best for gaming and working with multiple programs side-by-side. If you frequently have to reference other programs or documents while working, consider getting a second monitor—ideally one that’s 22-24 inches in size.
