How to Measure Computer Screen
Measuring a computer screen is a straightforward process, and it’s essential when you need to know the screen size for various purposes, such as buying a replacement monitor or calculating the dimensions for a custom screen protector. Here are the steps to measure a computer screen:
Turn off the Computer and Monitor:
- To ensure an accurate measurement, turn off your computer and monitor. This prevents any glare or reflections that could affect your measurement. Read about Brains of the Computer
Find the Measuring Tools:
- You will need a measuring tape or a ruler to measure the screen accurately. A soft, flexible measuring tape is preferable because it can conform to the curved edges of some monitors.
Measure Diagonally:
- The standard way to measure a computer screen is diagonally from one corner to the opposite corner. Start your measurement from the bottom-left corner (or bottom-right; it doesn’t matter as long as it’s a corner) and extend the measuring tape or ruler to the top-right (or top-left) corner. Ensure you measure only the visible screen area, excluding bezels or the monitor’s frame.

Read the Measurement:
- Take note of the measurement in inches or centimeters, depending on your preference. Typically, screen sizes are measured in inches. For example, you might measure a diagonal size of 24 inches.
Optional: Measure Other Dimensions:
- If needed, you can also measure the width and height of the screen separately. These measurements can be useful for specific applications, like designing custom screen protectors.
Record the Information:
- Write down the screen size measurement for your reference.
That’s it! You now have the screen size of your computer monitor. Remember to measure diagonally for the standard screen size specification, but you can also measure width and height if you need those dimensions for specific purposes.
Tools You’ll Need
Before we dive into the measurement methods, let’s gather the tools you’ll need for this task:
- Tape measure or ruler
- Calculator
- Pen and paper (or a digital note-taking device)
- Access to the internet (for online tools)
Now that you’re prepared, let’s start measuring!
Measuring the Screen Diagonally
One of the most common ways to measure a computer screen is by its diagonal length. To do this, follow these steps:
Turn off your computer screen to ensure an accurate measurement.
Position your tape measure or ruler at the bottom-left corner of the screen.
Extend it diagonally to the top-right corner.
Note down the height in inches or centimeters.
Measuring the Screen Width and Height
In addition to the diagonal measurement, you may need the screen’s width and height. To obtain these measurements:
Begin at the top-left corner of the screen.
measure the width from left to right.
Measure the size from top to bottom.
Record both measurements in inches or centimeters.
Measuring the Screen Bezel
If you want to include the frame (bezel) in your measurements, follow these steps:
Measure the diagonal length as previously described.
Then, measure the width of the bezel itself.
Deduct the bezel width from the diagonal length to get the screen size excluding the bezel.
Measuring the Screen Aspect Ratio
The aspect ratio determines the screen’s proportion. It’s typically expressed as a ratio of width to height (e.g., 16:9 or 4:3). To calculate the aspect ratio:
Divide the screen’s width by its size.
Express the result as a ratio (e.g., 16:9).
Calculating the Screen Size in Square Inches
Calculating the screen’s size in square inches can be helpful to when comparing different screens. To do this:
Multiply the width and height measurements obtained earlier.
The result is the screen size in square inches.
Understanding Resolution
Resolution refers to the number of pixels displayed on the screen. Higher resolution generally means sharper images. Common resolutions include Full HD (1920×1080) and 4K (3840×2160). Consider the resolution when choosing a screen for specific tasks.
Measuring a Laptop Screen
Measuring a laptop screen follows a similar process to measuring a desktop monitor. However, laptops have unique features, such as the bezel size and camera position.
Measuring a Curved Screen
Curved monitors require special consideration when measuring, as the curvature affects the dimensions. Measure the curve’s radius to get accurate width and height measurements.
Measuring a Projector Screen
Measuring a projector screen is essential for those interested in home theater setups. Follow the same width and height measurements principles, but ensure your measurements consider the entire projection surface.
Measuring a TV Screen
Measuring a TV screen is similar to measuring a computer monitor. The key difference lies in the additional considerations for TV features like bezel width and screen thickness.
Using Online Tools and Apps
You can also use online tools and apps to simplify the measurement process. Many websites and smartphone apps provide easy-to-use screen measurement features, making the process quick and hassle-free.
Common Mistakes to Avoid
When measuring a computer screen, there are common mistakes to avoid. These include measurement inaccuracies, ignoring the bezel, and not considering the aspect ratio. Be vigilant to ensure your measurements are precise.
Conclusion
This comprehensive guide covers various methods for measuring computer screens, including diagonal measurement, width and height, bezel inclusion, aspect ratio calculation, and more. With this knowledge, you can confidently measure your computer screen for any purpose.
FAQs
Q: Can I measure my screen while it’s turned on?
It’s best to turn off your screen to ensure an accurate measurement, especially when measuring diagonally.
Q: What’s the most common aspect ratio for monitors?
The most common aspect ratio for monitors is 16:9, ideal for widescreen content.
Q: Are there any specific considerations for measuring ultra-wide screens?
Yes, ultra-wide screens have unique measurements due to their extended width. Be sure to measure both the diagonal and width accurately.
Q: Can I use a digital ruler app for measurements?
Digital ruler apps can be convenient for accurate measurements, especially for smartphones and tablets.
Q: Why is it important to measure a TV screen’s bezel?
Measuring the bezel is crucial if you plan to mount your TV or need precise dimensions for a TV cabinet.
