How do you measure laptop screens: A guide to finding the right size

Table of Contents

I. Introduction

Measuring laptop screens is essential for a variety of reasons, whether it be to select the right accesories, to evaluate the compatibility of certain apps or games, or to simply ensure you have the ideal size for your preferred viewing experience. In this article, we dive into the specifics of how to measure laptop screens, the techniques, and tools involved, and what makes this guide unique among others.

II. Measuring laptop screens

A. Understanding the measurement terminologies

Before we dive into the actual process of measuring laptop screens, it’s important to understand the terms involved. This section covers the different measurement terminologies associated with laptops:

1. Diagonal measurement: The distance between two opposite corners of the screen, usually measured in inches. It includes only the visible area of the screen and not the bezels.

2. Aspect ratio: The proportion of the width to the height of the screen. The two most common aspect ratios for laptop screens are 16:9 and 16:10.

3. Resolution: The number of pixels that make up the screen. The higher the resolution, the better the image quality.

B. Tools for measuring laptop screens

There are various tools you can use to measure laptop screens. Here are some common ones:

1. Ruler or tape measure: A simple and accurate method to measure laptop screens manually.

2. Screen size calculator: Online calculators do the math for you, converting measurements into screen sizes once you’ve provided the necessary input.

3. Screen size finder software: Applications designed specifically for measuring laptop screens without the need for manual input.

III. How to measure laptop screens

A. Step-by-step guide for measuring screen size using a ruler or tape measure

1. Power off the laptop and lay it on a flat surface with the screen open.
2. Position the ruler or tape measure at one corner of the screen, on the inside border of the bezel.
3. Stretch the ruler or tape measure diagonally to the opposite corner, ensuring it’s also at the inside edge of the bezel.
4. Note down the size in inches for the diagonally measured distance, which is your laptop screen size.

B. Step-by-step guide for measuring screen size using screen size calculators

1. Using a ruler, measure the width and height of the visible screen while the laptop is on a flat surface.
2. Note down the measurements in inches.
3. Navigate to an online screen size calculator and input the measurements.
4. The calculator will automatically compute the screen size, which can be verified against your diagonal measurement.

C. Step-by-step guide for measuring screen size using screen size finder software

1. Install the screen size finder software on your laptop.
2. Launch the software and follow the prompts, inputting any required measurements, if necessary.
3. Allow the software to calculate and display your laptop screen size.

IV. Tips for accurate measurements

A. Positioning the laptop correctly

For most screen measuring methods, it’s crucial to have the laptop on a flat, stable surface with the screen fully opened. This ensures the measurements are taken accurately without any distortions.

B. Using the right tools

Choosing the right tools for the job ensures a more accurate measurement. A rigid ruler or tape measure is more suitable for manual measurements, while specialized software can provide even more precise readings.

C. Checking for accuracy

Double-checking your measurements can help avoid mistakes. Compare the calculated screen size from multiple methods, or re-measure the screen using the same or a different tool to verify the result.

V. Conclusion

In summary, measuring laptop screens can significantly enhance your overall experience, help you choose the right accessories, and ensure proper app compatibility. By understanding measurement terminologies, using the appropriate tools, and following our step-by-step guides, you’re well-equipped to take precise laptop screen measurements. Now that you know how to measure laptop screens, give it a try and optimize your viewing experience!


1. Why is it important to measure laptop screens?

Measuring laptop screens helps users select the right accessories, evaluate compatibility with various applications or games, and ensures an optimal viewing experience.

2. What is the most common aspect ratio for laptop screens?

The most common aspect ratios for laptop screens are 16:9 and 16:10.

3. Can I use a regular ruler to measure my laptop screen?

Yes, you can use a regular ruler or a tape measure to measure your laptop screen manually, but make sure it’s rigid and accurate.

4. Can I measure my laptop screen without any tools or software?

It’s difficult to measure your laptop screen precisely without using any tools or software, but you can attempt a rough approximation by comparing your laptop screen to known screen sizes and aspect ratios.

5. Is it easier to measure laptop screens with software or by hand?

Both methods have their advantages – measuring by hand is simple and requires no additional resources, while software can provide higher accuracy by accounting for various factors.

6. How do I find my laptop’s screen resolution?
