You’re shopping for a new laptop case, trying to adjust your display settings for the perfect clarity, or maybe you’re just curious. Knowing your laptop’s screen size is one of those simple but essential pieces of information. It’s not always obvious, and that little sticker on the device can sometimes be more confusing than helpful.
Fortunately, finding your laptop’s screen size is a quick and easy process that doesn’t require any technical expertise. You can usually get the answer in less than a minute using one of a few simple methods. Let’s look at the most reliable ways to measure your screen.
The Simple Tape Measure Method
This is the most straightforward and universal approach. All you need is a standard tape measure. You’ll want to measure the screen diagonally from one corner to the opposite corner. Make sure you are only measuring the visible screen area itself, not the plastic bezel or frame surrounding it. The number you get in inches is your screen size. For example, if you measure 15.6 inches from the bottom-left to the top-right of the screen, you have a 15.6-inch display.
Checking Your Laptop’s Model Number
If you don’t have a tape measure handy, your laptop’s model number holds the key. Look for a sticker on the bottom of your laptop, inside the battery compartment, or sometimes on the palm rest near the keyboard. The model number will look something like “HP Pavilion 15-eg0023nr” or “Lenovo IdeaPad 3 15ITL6.” The number right before the dash or in the main name often indicates the screen size—in these examples, “15” signifies a 15.6-inch screen. You can then search for this full model number online to find the detailed specifications, which will always list the exact screen size.
Using Your Computer’s Settings
Your operating system can also provide this information, though it sometimes requires an extra step. On Windows, go to Settings > System > Display. Scroll down to “Display resolution.” While the resolution (e.g., 1920 x 1080) is shown, the physical size usually isn’t. However, the linked “Advanced display” settings might list your monitor’s model name, which you can search. On a Mac, click the Apple logo > “About This Mac.” The “Overview” tab will show the screen size directly, such as “13.3-Inch (2560 x 1600).”
Why Screen Size Matters
Knowing your screen size is practical for more than just curiosity. It ensures you buy a laptop bag or sleeve that fits perfectly. It also helps when you’re troubleshooting display issues or comparing your device to newer models for a potential upgrade. A larger screen can be better for multitasking and media, while a smaller one offers superior portability.
With these simple tricks, you’ll never have to guess your laptop’s screen size again. A quick diagonal measurement or a glance at your model number is all it takes to get the information you need.
