Knowing how to check the screen size of a laptop is useful for many reasons, such as determining compatibility with various accessories, deciding on a new purchase, or even just better understanding your current device. In this article, we will cover different ways to check the screen size of a laptop and understand the relationship between screen size and screen resolution.

Ways to Check Laptop Screen Size

There are a few different ways to find out the screen size of your laptop, from physically measuring the screen to checking the specifications or using online tools. Let’s explore these options in detail.

Option 1: Measure the Screen Manually

a. Materials Needed

The simplest way to determine the screen size of a laptop is by manually measuring the display. To do this, you’ll need a measuring tape or a ruler.

b. Measuring the Screen

To measure the screen size, simply place the ruler or measuring tape diagonally across the laptop screen, starting from one corner and extending to the opposite corner. Be sure to only measure the display area, not including the bezel (the frame around the screen). The measurement is typically expressed in inches, representing the screen size.

c. Warning About Removing the Laptop Bezel

It’s important to note that you should not attempt to remove the laptop bezel to measure the screen. Doing so can potentially cause damage to the display, bezel, or other internal components.

Option 2: Check Laptop’s Specifications

a. Checking the Manufacturer’s Website

Another way to check the screen size of a laptop is by checking its specifications, which can typically be found on the manufacturer’s website. To find the specifications, you’ll need the laptop’s model number or product name, which is usually located on a sticker on the bottom of the device or within the device’s settings.

b. Checking the Product Label

In some cases, the screen size may be listed directly on the product label, which is often found on the bottom or side of the laptop. This may appear as a number followed by the abbreviation in for inches, such as 15.6 in.

c. Checking Device Settings

For some laptops, you can find the screen size within the device’s settings. On Windows devices, you can check the display settings by right-clicking on the desktop and selecting Display settings. On macOS devices, you can check the display settings by going to System Preferences and selecting Displays.

Option 3: Use Online Tools

b. Popular Online Tools

Some popular online tools for finding laptop screen sizes include,, and Simply input your laptop’s model number, and these sites will provide you with the screen size information.

Difference Between Screen Size and Screen Resolution

1. Explanation of Screen Size

Screen size refers to the physical dimensions of the display area of a laptop, measured diagonally in inches. Larger screens generally offer more screen real estate and can display more content, while smaller screens make for more portable devices.

2. Explanation of Screen Resolution

Screen resolution refers to the number of pixels that make up the display. A higher resolution means more pixels, which generally results in sharper, more detailed images. Resolution is expressed as the number of horizontal pixels by the number of vertical pixels, such as 1920×1080 or 2560×1440.

3. Why Both Are Important

Both screen size and resolution are important factors when considering a laptop, as they determine the overall visual experience you’ll get from the device. A larger screen with a higher resolution can provide a more immersive experience, especially for activities such as gaming and video editing, while a smaller screen with a lower resolution may be more suitable for basic tasks and portability.

Choosing the Right Screen Size for Your Needs

1. Benefits of Larger Screens

Larger laptop screens provide more screen real estate, allowing you to have multiple windows open at once, view detailed images and videos, and enjoy an immersive gaming experience. These screens are particularly beneficial for tasks such as video editing and graphic design or for users who prefer a more visually spacious workspace.

2. Benefits of Smaller Screens

Smaller laptop screens offer better portability, making them ideal for users who frequently travel or need a lightweight device. Smaller screens are also more power efficient, so they may provide slightly longer battery life than their larger counterparts, although this can vary depending on the specific device and its other components.

3. Laptop Screen Size Considerations for Specific Activities

When choosing the right screen size for your needs, consider the primary activities you’ll be using your laptop for. Here are some general guidelines:

– For gaming and multimedia consumption, a larger screen with higher resolution is often preferred, providing an immersive experience and detailed visuals.
– For professional tasks, such as graphic design, video editing or programming, a larger, high-resolution screen can be beneficial, as it allows for more screen real estate and better visibility.
– For basic tasks, such as browsing the internet, word processing, or watching videos, a smaller screen may suffice, offering the added benefit of better portability.


Knowing how to check the screen size of a laptop is an essential aspect of understanding your device and choosing the right model for your needs. There are several methods to determine the screen size, including measuring the display, checking the laptop’s specifications, or using online tools. It’s also important to understand the difference between screen size and screen resolution and to choose a laptop screen size that best suits your individual needs and preferences.


1. What is the most common laptop screen size?

The most common laptop screen sizes are 13 to 15 inches, offering a good balance between portability and usability for most users.

2. What is considered a large laptop screen size?

A laptop screen size of 17 inches or larger is typically considered large, often being used for gaming, multimedia, and professional tasks.

3. Can you replace a laptop screen with a different size screen?

Replacing a laptop screen with a different size screen is generally not recommended, as the laptop’s internal components and chassis are designed specifically for the original screen size.

4. How does screen size affect battery life?

Larger screens typically consume more power, which can negatively impact battery life. However, this effect can be mitigated by factors such as screen brightness, resolution, and the efficiency of other laptop components.

5. How do I find the measurement of my laptop screen without a ruler or measuring tape?

You can still estimate the screen size by measuring the distance diagonally with an object of known length, such as a credit card or sheet of paper, and then comparing it against a ruler or measuring tape.

6. How does laptop screen size impact ergonomics and user comfort?

Larger laptop screens can provide a more comfortable viewing experience, reducing eye strain and allowing for better posture. However, they can also make the laptop heavier and less portable, potentially causing discomfort when carrying the device for extended periods.

7. Are there any disadvantages to a larger laptop screen size?

The main disadvantages of larger laptop screens include increased weight, reduced portability, and potentially shorter battery life due to higher power consumption.
