Monitor - Convert 27 inches to cm

Units of length ﹣ 27 inches in cm

Modern office or gaming monitors are getting bigger and bigger. 24", 27", or even 30" are no longer uncommon. The high resolution, especially in 16:9 format, allows the use of the large screens without unnecessary strain on the eyes. We would like to inform you about the correct dimensions of the devices and help you with your purchase decision. Let’s now take a look at all 27" devices:: What are the real dimensions of a 27" screen? First, the most important information:

27 inches in cm equals 68.58 cm

This is the diagonal screen size of the monitor. Use our online calculator to determine other screen sizes:


27-inch monitors the real dimensions

We have now learnt that the screen diagonal for 27-inch devices is approximately 68.6 centimeters. Does this device meet your expectations, or is it suitable for your workplace? To determine this, you will need the actual screen dimensions (width x height) in centimeters. Important: We assume a 16:9 screen here. The actual dimensions are:

Width: 59.5 cm
Heigth: 33.5 cm
Diagonal: 68.6 cm (27")

Monitor size overview

Monitor sizes in comparison

Our size chart gives an overview of the common monitor formats, starting with the aspect ratio 16:9. Feel free to compare this size with a 24-inch monitor or a 30-inch monitor.

In addition to the diagonals, the chart also shows the screen width and height. You can also use this information to calculate the screen area in square centimeters (cm²). Multiplying the width and height gives the area of the screen. A 27-inch monitor with the common aspect ratio of 16:9 has a screen area of 59.5 cm × 33.5 cm = 1,993.25 square centimeters (cm²). In contrast, the largest 30-inch screen shown in the chart has a screen area of 66 cm × 37 cm = 2442 cm². If your desk is large enough and you often work with many programme windows open, it may be worth choosing an even larger screen.
