To access it, click on the Apple menu in the top-left corner of your screen and select “About This Mac.” In the window that appears, click on “System Report…”
In the System Report window, navigate to the “Graphics/Displays” section. Here, you will find information about your display, including its resolution and the display’s manufacturer and model number.
Similar to the Windows method, use the display model number to search online for the specific screen size. A simple search like “MacBook Pro [Year] display size” can often provide the answer quickly.
Finding Your Laptop’s Model Number
The laptop’s model number is essential for pinpointing the exact specifications, including screen size. There are several ways to locate this crucial piece of information.
Checking the Laptop’s Exterior: Most laptops have a sticker on the bottom or around the screen bezel that displays the model number. Look for a label that includes text like “Model,” “Model No.,” or “Type.” The sticker may also contain the serial number and other identifying information.
Examining the Original Packaging: If you still have the original box that your laptop came in, the model number is often printed on a label on the packaging. This is a reliable source of information.
Consulting Your Purchase Receipt or Invoice: Your purchase receipt or invoice should clearly state the laptop’s model number. This is a quick and easy way to retrieve the information.
Once you have the model number, you can visit the manufacturer’s website (e.g., Dell, HP, Lenovo, Apple) and search for your laptop model. The product page will typically list all the specifications, including the screen size.

Websites like CNET, GSMArena, and Laptop Specs allow you to search for your laptop model and access its specifications. Simply enter the model number into the search bar and browse the listed details. Be sure to verify the information with the manufacturer’s website whenever possible.
These websites often provide additional information such as the screen resolution, panel type, and other relevant details.
Understanding Screen Size Measurements
Laptop screen sizes are typically measured diagonally in inches. This measurement refers to the distance from one corner of the screen to the opposite corner.
It’s important to understand that the bezel (the frame around the screen) is not included in the screen size measurement. For example, a 15.6-inch laptop screen will have a diagonal measurement of 15.6 inches for the active display area.
When comparing laptop screen sizes, it’s also important to consider the aspect ratio. The aspect ratio is the ratio of the screen’s width to its height. Common laptop aspect ratios include 16:9 and 16:10. Laptops with a 16:10 aspect ratio will have a slightly taller screen than those with a 16:9 aspect ratio, even if the diagonal screen size is the same.
When to Contact the Manufacturer
If you’ve exhausted the methods above and are still unable to determine your laptop screen size, contacting the manufacturer’s support team is a viable option.
Provide them with your laptop’s model number and any other relevant information you have. They should be able to provide you with the screen size and any other specifications you need.
Many manufacturers offer online chat support, phone support, and email support. Choose the method that is most convenient for you. Before contacting support, gather all the information you have about your laptop to expedite the process.
Verifying Screen Size When Buying Replacement Parts
If you’re buying a replacement screen, it is absolutely crucial to verify the screen size. Ordering the wrong size can lead to compatibility issues and prevent the screen from fitting properly.
Always double-check the screen size before placing your order. Pay close attention to the dimensions listed in the product description. If you are unsure, contact the seller or the manufacturer of the replacement screen for clarification.
In addition to screen size, you should also verify other specifications such as the screen resolution, connector type, and backlight type. These factors can also affect compatibility.
Conclusion
Determining your laptop screen size online is generally a straightforward process. By utilizing the methods outlined in this guide, you can quickly and accurately find the information you need. From leveraging your operating system’s built-in tools to consulting online databases and manufacturer websites, there are several reliable ways to uncover this essential specification. Remember to verify the information with multiple sources and, when in doubt, contact the manufacturer for assistance. With the right approach, you can confidently determine your laptop screen size and use this knowledge for various purposes, from purchasing accessories to ordering replacement parts.
How accurate is finding the laptop screen size using online methods compared to measuring it physically?
Finding your laptop screen size online using methods like checking your laptop’s model number on the manufacturer’s website or using online databases is generally very accurate. These sources usually provide the exact specifications as defined by the manufacturer. This precision ensures that the information you receive is reliable, especially when compared to manual measurements, which are prone to human error.
However, slight variations may occur depending on how the manufacturer defines “screen size” (e.g., including or excluding the bezel). Physically measuring your screen gives you a visual confirmation, but accuracy depends on the tool you use and your precision. The online method is typically preferred for consistency and convenience, especially when you need the exact specifications for purchasing screen protectors or replacement parts.
What if my laptop model number isn’t listed on the manufacturer’s website or online databases?
If you can’t find your laptop model number listed on the manufacturer’s website or online databases, you have a few alternative options. First, double-check the model number itself – ensure you’ve transcribed it correctly, paying attention to special characters or capitalization. Sometimes a slight mistake can lead to a failed search.

Before using a third-party website, check its reputation by reading reviews and verifying its security credentials (e.g., looking for an SSL certificate). Stick to well-known and trusted sources whenever possible, or cross-reference the information with other sources to ensure accuracy.
What if I’ve upgraded my laptop screen previously? How does this affect finding the screen size online?
If you’ve previously upgraded your laptop screen to a different size, relying on the original model number information online will likely provide inaccurate results. The online databases and manufacturer websites will only reflect the screen size that came with the laptop when it was originally manufactured. The upgraded screen’s size will differ.
In this scenario, you must physically measure the screen diagonally to determine its current size. This will provide the most accurate information for ordering screen protectors or replacement parts. Alternatively, if you know the specifications of the screen you used for the upgrade (e.g., from a purchase receipt or product documentation), you can use that information.
Why is knowing the laptop screen size important?
Knowing your laptop screen size is crucial for several reasons. Primarily, it’s essential when purchasing accessories like screen protectors, privacy filters, or replacement screens. Using the wrong size will render these accessories unusable. Furthermore, understanding your screen size helps in optimizing display settings for the best viewing experience.
Besides accessories, screen size is an important factor in determining the portability and usability of your laptop. A larger screen might be better for multitasking and media consumption, but it comes at the cost of increased size and weight. Conversely, a smaller screen offers better portability but might be less comfortable for prolonged use.
How do I find the correct laptop model number?
The laptop model number is typically located in a few different places. Commonly, you can find it printed on a sticker on the bottom of the laptop, often near the serial number. Look for labels that clearly indicate “Model Number,” “Model No.,” or “Model.” The sticker might be hidden beneath the battery compartment, so you might need to remove the battery to access it.
Alternatively, you can often find the model number within the laptop’s system information. On Windows, search for “System Information” and open the app. The model number will be listed under “System Model” or “BaseBoard Product.” On macOS, go to “About This Mac” from the Apple menu. The model information might be listed directly, or you might need to click on “System Report” for more details.
