# How do you measure a computer monitor size?

When it comes to buying a computer monitor, knowing its size is crucial. The size of a monitor refers to its diagonal measurement, which is the distance from one corner of the screen to the opposite corner. In this article, we will explore the various ways to measure a computer monitor size accurately.

## How to Measure a Monitor Size

1. Measure the Screen Diagonally: The most reliable method to determine the size of a computer monitor is by measuring its screen diagonally. Start from one corner of the screen and measure up to the opposite corner, ensuring to only measure the screen and not the border.

2. Convert Inches to Centimeters: If you want to know the size in centimeters, you can convert the inches measurement by multiplying it by 2.54. This conversion will give you the screen size in centimeters.

3. Consider Aspect Ratio: It’s essential to consider the aspect ratio of the monitor, as it can affect the viewing experience. Common aspect ratios include 16:9, 16:10, and 4:3. Remember that changing the aspect ratio will not affect the physical size of the monitor, but it will affect the screen’s visible area.

### 1. Can I measure the monitor size by measuring the width?

No, measuring the width alone won’t give you an accurate size since monitors come in various aspect ratios. Measuring the diagonal is more reliable.

### 2. Can I include the monitor bezel when measuring the size?

No, the bezel is not considered part of the screen size. Only the actual screen area is included in the measurement.

### 3. What if my monitor is curved?

For curved monitors, you still measure the diagonal from one corner to the opposite, following along the curve.

### 4. Is there any standard screen size for monitors?

There is no specific standard size for monitors, as they are available in a variety of sizes ranging from small screens below 20 inches to larger screens exceeding 30 inches.

### 5. Does measuring the size of a laptop screen differ from a desktop monitor?

No, the method of measuring remains the same for both laptops and desktop monitors.

### 6. Are there any measurement guidelines to consider while buying a monitor?

Yes, it is recommended to choose a monitor size based on your desk space, viewing distance, and the intended use, such as gaming or office work.

### 7. Can I measure the size of an old CRT monitor using the same method?

Yes, you can measure the size of CRT monitors using the same diagonal measurement method.

### 8. Can I rely on the screen size mentioned on the product packaging?

Product packaging often mentions the approximate size, but it is always better to measure the monitor size yourself to ensure accuracy.

### 9. Are there any online tools available to measure monitor size?

Yes, there are several online tools and websites available where you can measure your monitor size by following their instructions.

### 10. Are there any size variations between different brands of monitors?

Yes, different brands may slightly differ in their measurement conventions, but overall, the size is standardized.

### 11. Can I use a measuring tape to measure the monitor size?

While you can use a measuring tape for rough measurements, using a ruler or a measuring device with a higher precision is recommended for accurate results.

### 12. Are monitor size and screen resolution the same?

No, monitor size and screen resolution are not the same. Monitor size refers to the physical dimensions, while screen resolution refers to the number of pixels that can be displayed on the screen.

In conclusion, measuring the size of a computer monitor is essential before purchasing one. Remember to measure the screen diagonally, convert inches to centimeters if needed, and consider the aspect ratio. Additionally, keep in mind the various factors that can influence your decision, such as viewing distance and the intended use of the monitor.
