How to measure monitor size
When buying or using a monitor, it's important to know exactly its dimensions. Monitor dimensions are usually expressed as diagonal length, but actual measurement methods may vary depending on your needs. This article will introduce in detail how to measure the monitor size and provide relevant data for reference.
1. Basic concepts of monitor size

The size of a monitor usually refers to the diagonal length of the screen in inches (1 inch = 2.54 centimeters). The following is a comparison table of common monitor sizes:
| Dimensions (inches) | Diagonal length (cm) | Common uses |
|---|---|---|
| 19 | 48.26 | Office and home use |
| 24 | 60.96 | entertainment, design |
| 27 | 68.58 | Games, professional design |
| 32 | 81.28 | Multimedia, eSports |
2. How to measure monitor size
1.diagonal measurement: This is the most commonly used method. Use a measuring tape or tape measure to measure the diagonal length in inches or centimeters from the lower left corner to the upper right corner (or upper left corner to lower right corner) of the screen.
2.width and height measurements: If you need to know how much space your monitor actually takes up, you can measure the width and height of the screen. The following are common monitor aspect ratios:
| aspect ratio | Common sizes | Features |
|---|---|---|
| 16:9 | Most modern monitors | Standard widescreen |
| 16:10 | Some professional monitors | More suitable for office |
| 21:9 | ultrawidescreen monitor | Cinematic experience |
3.Frame measurement: If you need to consider the overall size of the monitor (including the frame), you also need to measure the frame width. The following are common monitor bezel types:
| Border type | width range | Features |
|---|---|---|
| Ultra narrow bezel | 1-3mm | Ideal for multi-screen splicing |
| Standard border | 5-10mm | most monitors |
| wide border | 10mm or more | vintage monitor |
3. Measurement precautions
1. Make sure the display is turned off when measuring to avoid accidentally touching it.
2. If the measurement unit is centimeters, divide by 2.54 to convert to inches.
3. The measurement method for curved monitors is the same as that for flat monitors, but the actual viewable area will vary slightly due to curvature.
4. For monitors with stands, also measure the overall height and depth.
4. Monitor size selection suggestions
Choose the appropriate monitor size according to the usage scenario:
| Usage scenarios | Recommended size | Sight distance recommendations |
|---|---|---|
| Daily office | 22-27 inches | 50-70cm |
| Professional design | 27-32 inches | 60-80cm |
| Games and entertainment | 24-34 inches | 50-100cm |
| multimedia center | 32 inches or more | More than 1m |
5. Popular monitor size trends
According to recent market data, the following is the distribution of popular monitor sizes in 2023:
| size range | market share | year-on-year growth |
|---|---|---|
| 24 inches and below | 25% | -3% |
| 27 inches | 35% | +5% |
| 32 inches | 20% | +8% |
| 34 inches and above | 20% | +12% |
It can be seen from the data that 27-inch monitors are still the mainstream choice, but large-size monitors are growing rapidly, especially ultra-widescreen monitors above 34 inches.
Summary
Accurately measuring your monitor size requires taking into account factors such as diagonal length, aspect ratio, and bezels. Choosing the right monitor size should take into account factors such as usage scenario, desktop space, and viewing distance. With the development of technology, larger size and higher resolution displays are becoming a new trend. I hope this article helps you better understand and choose monitors.
