How Do I Tell the Size of My Laptop Screen?
Laptops with smaller screens tend to be lighter and more portable, while those with larger screens can be more pleasant to use and easier to read. If you’re thinking about buying a new laptop of a different size or recommending yours to a friend, you might want to know your current laptop screen size. Unfortunately, determining screen size can be confusing, since the screen size is not measured straight across the laptop screen either vertically or horizontally.
Things You'll Need
- Measuring tape
Open your laptop.
Place the end of the measuring tape in the top left corner of your laptop screen. Do not measure all the way to the corner of the laptop, only the screen itself.
Pull your measuring tape snugly to the bottom right corner of your laptop screen.
Read the measurement on your measuring tape. This will tell you the screen size of your laptop.
Tips & Warnings
- If you aren’t sure you’re getting a precise reading by this method, use the Pythagorean Theorem to be even more exact. Measure your laptop screen from top to bottom then square that number. Then measure straight across your laptop and square that number. Add these two numbers together, then use a calculator to find the square root of that sum. This is your laptop screen size.
