Measuring your laptop screen size is an essential step when looking to purchase a laptop case or screen protector. Fortunately, it is a simple process that requires only a few measurements. In this guide, we’ll go over the steps to measure your laptop screen size accurately.
Step 1: Determine the Screen Type
Before measuring your laptop screen size, you need to know the type of screen you have. Laptop screens come in different shapes, including square, standard, and widescreen. You can find out the screen type by checking the laptop’s specifications or by measuring the screen’s aspect ratio.
Step 2: Measure the Diagonal Length of the Screen
To measure the diagonal length of your laptop screen, place the end of a tape measure at the bottom left corner of the screen and measure diagonally to the top right corner of the screen. Round up to the nearest whole number, and this will give you the screen size in inches.
Step 3: Measure the Screen Height and Width
To measure the height and width of your laptop screen, place the end of a tape measure at the bottom left corner of the screen and measure straight up to the top of the screen to find the height. Then, measure from the bottom left corner to the bottom right corner to find the width. Make sure to measure only the visible screen area and not the bezel around the screen.
Step 4: Use the Aspect Ratio to Calculate Screen Size
If you don’t have a tape measure, you can calculate your laptop screen size using the aspect ratio. The aspect ratio is the ratio of the screen width to its height. It is usually expressed as two numbers separated by a colon, such as 16:9 or 4:3. The first number represents the width, and the second number represents the height.
To calculate the screen size using the aspect ratio, multiply the width by the aspect ratio. For example, if you have a widescreen laptop with an aspect ratio of 16:9 and a width of 14 inches, the height would be 7.87 inches (14/16 x 9). Then, use the Pythagorean theorem to calculate the diagonal length, which is the hypotenuse of a right triangle. In this case, the diagonal length would be 16.1 inches (sqrt(14^2 + 7.87^2)).
Step 5: Check for Compatibility
Once you have measured your laptop screen size, make sure to check for compatibility when purchasing a laptop case or screen protector. The case or protector should be designed to fit your laptop screen size and type. If the case or protector is too small or too large, it may not provide the necessary protection or may not fit properly.
In summary, measuring your laptop screen size is a straightforward process that requires only a few measurements. Determine the screen type, measure the diagonal length, and height and width of the screen, or use the aspect ratio to calculate the screen size. Make sure to check for compatibility when purchasing a laptop case or screen protector to ensure proper fit and protection.
