When it’s time to buy a new laptop bag, a screen protector, or even list your old device for sale, knowing the exact screen size is crucial. Many people make the simple mistake of measuring the wrong part of the laptop, which can lead to ordering the wrong accessories. It’s a quick and easy process once you know the correct method.
The Right Way to Measure Your Screen
To measure your laptop screen correctly, you only need a standard measuring tape. The measurement is always taken diagonally, from one corner of the screen to the opposite corner. The key is to measure only the viewable area of the screen itself. Do not include the plastic bezel (the black or colored frame) around the screen in your measurement. Place your tape measure at the bottom left corner of the screen and stretch it to the top right corner, keeping it tight against the glass for an accurate reading in inches.
Avoiding Common Measuring Mistakes
A frequent error is measuring the entire laptop lid from edge to edge, including the bezel. This will give you a number that is larger than the actual screen size and won’t match the manufacturer’s specification. Another point of confusion can be the screen’s aspect ratio, like 16:9 or 16:10. While this affects the screen’s shape and height, it does not change how you measure the diagonal size. The diagonal measurement is the universal standard for screen size.
Finding the Size Without a Tape Measure
If you don’t have a tape measure handy, there are other reliable ways to find your screen size. The quickest method is to check your laptop’s model number, which is usually on a sticker on the bottom of the device. A quick online search of that model number will bring up the detailed specifications, including the screen size. You can also check your computer’s system information settings, though this sometimes requires a bit more technical navigation to find the exact display details.
Knowing how to accurately measure your laptop screen saves time and prevents the hassle of returning ill-fitting accessories. By focusing on the diagonal screen area alone, you can confidently find the perfect match for your needs.
