# How to measure a monitor screen?

Measuring a monitor screen is an essential step in various scenarios, whether you are looking to buy a new monitor, replace an existing one, or simply want to know its dimensions for a specific purpose. While it may seem like a straightforward task, there are a few key points to consider to ensure accurate measurements. In this article, we will guide you through the process of measuring a monitor screen effectively.

## How to Measure a Monitor Screen?

To measure a monitor screen, follow these simple steps:

1. **Determine the Type of Measurement**: There are two common methods to measure a monitor screen, either diagonally or horizontally. The diagonal measurement is the most widely used and provides the overall screen size, while the horizontal measurement focuses on the width.

2. **Prepare a Measuring Tape**: You will need a flexible measuring tape, preferably one that is at least as long as the diagonal length of your monitor. Make sure the tape is flat, without any kinks or bends, to ensure accuracy.

3. **Turn off the Monitor**: Before taking any measurements, it is crucial to turn off the monitor. This eliminates any distortion caused by a powered display.

4. **Locate the Starting Point**: Identify the starting point of your measurement. For diagonal measurement, this is typically the top-left corner of the screen. For horizontal measurement, start from either the left or right edge of the screen.

5. **Measure Diagonally**: Gently extend the measuring tape from the starting point to the bottom-right corner of the screen, following the diagonal pattern. Keep the tape straight and aligned with the edges of the screen, without bending or angling it.

6. **Take Note of the Measurement**: Once the measuring tape is stretched along the diagonal length, read the measurement indicated by the tape’s endpoint. This measurement represents the screen size in inches or centimeters, depending on the unit used by the tape.

7. **Measure Horizontally**: If you also want to measure the width of the monitor, place the measuring tape horizontally from the starting point to the opposite edge of the screen, either left or right. Ensure the tape is parallel to the edge and remains straight throughout the measurement.

8. **Record the Horizontal Measurement**: As before, carefully read the measurement displayed where the tape endpoints align with the screen’s edge. Note down this measurement, which represents the screen width.

Now that you know how to measure a monitor screen, you may have additional questions regarding the process. Here are some frequently asked questions and their brief answers:

### 1. Can I use a ruler instead of a measuring tape?

Yes, you can use a ruler if it is long enough to measure the diagonal or horizontal length of your monitor screen accurately.

### 2. Should I include the monitor’s bezel in the measurement?

No, when measuring a monitor screen, you should only measure the visible part of the screen and exclude the bezel.

### 3. What if my measuring tape is not long enough?

If your measuring tape is not long enough to measure the diagonal length of the screen in one go, you can measure it in separate sections and then add up the measurements.

### 4. Is there a difference between the screen size and viewable area?

Yes, manufacturers often list the size of the entire monitor, including the bezel. The viewable area refers to the actual screen size, excluding the bezel.

### 5. How accurate should my measurements be?

For most purposes, a rounded measurement to the nearest inch or centimeter should be sufficient. However, if precise dimensions are required, consider using a more accurate measuring tool.

### 6. Is there a standard measurement unit for monitor screens?

The standard measurement unit for monitors is inches; however, some manufacturers also provide measurements in centimeters.

### 7. Can I measure a curved monitor the same way?

While the process is similar, measuring a curved monitor screen requires positioning the measuring tape along the curvature of the screen instead of a straight line.

### 8. Can I measure a monitor screen while it’s on?

It is recommended to turn off the monitor before measuring it to ensure accurate results. The on-screen display may introduce distortions that affect the measurements.

### 9. Can I use a digital laser distance meter to measure a monitor screen?

Yes, a digital laser distance meter can be used effectively to measure a monitor screen, providing accurate results without physical contact.

### 10. Are there any alternative methods to measure a monitor screen?

If a measuring tape or laser distance meter is not available, you can estimate the screen size by comparing it to a standard object of known dimensions, such as a ruler or a credit card.

### 11. Should I measure the height of the monitor too?

The height of the monitor is usually proportional to its width, considering common aspect ratios. Therefore, measuring the width should be sufficient to determine the overall size.

### 12. Is there a difference between measuring a desktop monitor and a laptop screen?

The process of measuring both desktop monitors and laptop screens is the same. However, laptop screens tend to have different aspect ratios and smaller sizes compared to desktop monitors.
