Summary

Physical Dimension of Computer Monitor Size Chart

Related: Resolution Size Chart And Difference From Screen Size

Let’s start by taking a look at the physical dimensions of different computer monitors. For the purpose of this article, we’ll be using two measures:

  • The Width of the monitor
  • The Height of the monitor

You can find these measurements in inches and centimeters by looking at the product description or specs for your monitor. Keep in mind that width and height are not always proportional. For example, a widescreen monitor will have a different width-to-height ratio than a standard monitor.

Check the size chart below for the common width and height measurements for different monitor sizes.

Screen Resolution Dimension of Computer Monitor Size Chart

The next thing that you need to look at is the screen resolution. This is the number of pixels that make up your monitor. The higher the screen resolution, the more information that can fit on your screen.

When it comes to screen resolution, bigger is not always better. If you sit too close to a high-resolution monitor, you may experience eye strain. Conversely, if you sit too far away from a low-resolution monitor, the individual pixels will be visible, and you won’t be able to see the big picture.

The ideal screen resolution for your needs depends on the size of your monitor and how far away you sit from it. Generally speaking, the larger the monitor, the higher the screen resolution you’ll need.

The aspect ratio is the width of the screen compared to the height. The most common aspect ratio for monitors is 16:9. This means that for every 16 inches of width, there will be 9 inches of height.

Other popular aspect ratios include 21:9 (ultrawide) and 4:3. Widescreen monitors are best suited for gaming and watching movies, while ultrawide monitors are great for productivity.

The table below shows the ideal screen resolution for different monitor sizes at 96 dpi.
