how to measure laptop size

A laptop size that’s right for you is crucial to comfortable and efficient computing. Knowing how to measure laptop size is important when you’re buying a new laptop or finding the perfect laptop bag. This comprehensive guide will walk you through how to measure laptop size, both screen size and overall size. Here’s how to make sure your laptop fits perfectly for any purpose. Let’s get started!

Step 1: Measure the Laptop Screen Size

The screen size is one of the most critical aspects of a laptop. It determines how much screen real estate you have for your work, entertainment, or browsing needs. To measure the laptop screen size, follow these steps:

1.1 Turn off the Laptop:

Ensure your laptop is powered off to avoid any distractions while measuring.

1.2 Locate the Screen Bezel:

The screen bezel is the frame around the display. Measure the diagonal distance from one corner of the bezel to the opposite corner in inches. Use a measuring tape or a ruler for accurate measurements.

1.3 Round to the Nearest Whole Number:

Laptop screen sizes are typically rounded to the nearest whole number. For example, if your measurement is 13.5 inches, it would be considered a 14-inch laptop.

Step 2: Measure the Laptop Dimensions

Beyond the screen size, you may also want to measure the overall dimensions of your laptop to ensure it fits into specific bags, cases, or compartments. To do this, follow these steps:

2.1 Measure the Width:

Place your measuring tape or ruler horizontally across the widest part of the laptop, which is typically from one side of the laptop to the other.

2.2 Measure the Depth:

Measure the depth of the laptop from the front edge to the back edge. This measurement should be taken with the laptop closed.

2.3 Measure the Height:

Measure the height of the laptop by placing the measuring tape or ruler vertically from the bottom to the highest point, which may include any protruding parts.

Step 3: Verify the Laptop Model for Accuracy

To ensure complete accuracy, it’s a good idea to cross-check your measurements with the official specifications of your laptop model. Visit the manufacturer’s website or refer to the laptop’s user manual to find the exact screen size and dimensions provided by the manufacturer.


It’s essential to know how to measure laptop size accurately before buying a new laptop or choosing accessories. Using this comprehensive guide, you’ll be able to measure your laptop’s screen size and dimensions with confidence. It’s important to measure your laptop diagonally and round it up to the nearest whole number, as well as its width, depth, and height to understand its size. After reading this, you’ll be able to find the perfect laptop that matches your needs and preferences.
