Monitor Viewing Distance Calculator | Monitor PPI Calculator

Many people choose a monitor by size and resolution, but then find that a 27-inch 1440p screen can look blurry or too intense once it’s on their desk. Viewing distance is the crucial element they overlook. Pixel density by itself does not provide the whole picture; even a sharp, high-PPI screen can display visible pixels if you sit too close. However, if you sit too far away, your eyes won’t be able to see the additional resolution. It’s preferable to use a monitor viewing distance calculator that starts with the depth of your actual desk, rather than just the numbers on a spec sheet, to get the best fit for your setup.

On a shallow desk, this is more important than on a deep one. Even though the same panel would appear perfectly sharp on a 36-inch deep desk, a 32-inch 4K monitor may sit close enough on a 24-inch desk that you can see individual subpixels at the edges of text. You can avoid the typical cycle of upgrading to a larger panel, finding it’s uncomfortably close, and then downgrading again by getting this number right before you buy.

Enter your monitor’s diagonal size, its resolution, and your desk depth, and the calculator returns your display’s exact PPI along with a recommended viewing distance range. If your desk depth is not within that range, you can determine whether a particular screen size and resolution combination will work at your desk before you purchase it, rather than after it has been unboxed. Since an arm’s extension range dictates how much you can actually alter distance after the fact, a monitor arm must also consider this.
