How To Measure Laptop Size

When purchasing a new laptop, the size is the second most significant consideration after the model and make. It is also necessary while selecting a laptop bag. The nature of your requirements may affect the size of your laptop.

Students, freelance writers, and professionals, for example, prefer thin and small-sized computers. However, programmers, web developers, and professional gamers choose laptops with huge screens. The size of the computer is computed in the same manner as a TV or monitor. Its dimension is in inches. Laptops are often available in 11-inch, 13-inch, 14-inch, 15-inch, and 17-inch sizes.

Laptops may be an excellent method to do tasks when away from family, friends, or the office. And, despite the small size, you get nearly the same capabilities as a desktop computer. With their tiny form factor and extended battery life, current thin and light laptops are easy to transport anywhere. However, while traveling with anything portable, it is critical to consider its size and form.

Similarly, whether you are purchasing a new laptop or already own one, you should assess its dimensions. And, whereas the screen size may appear to be that of a laptop, there is much more to consider.

As a result, as stated below, we are here to teach you how to measure laptop size. You may also read about the significance of measuring your laptop down below. So, whether you’re buying a new laptop or checking the size of your existing one, make sure to read all the way through.

How Do You Measure a Laptop?

You may wish to get started immediately now that you understand the significance of examining the size of your laptop. But first and foremost, you’ll need a tape measure. Once you’ve done so, you can go through and verify each of your laptop’s steps one by one:

Screen Size Calculation

The screen size is among the first things to consider when purchasing a laptop. The screen size not only influences the sleek physical design of your computer, but it may also influence your whole computing experience. Move your tape measure horizontally from one border to the directly opposite one to determine the larger screen of your laptop. Depending on the make of your laptop, screen sizes range from 11 to 17 inches.

Height Measurement

If you decide on a thin, light laptop, you must examine its height and width. To do so, place the laptop on a level surface and determine the distance between the top and the ground. After taking this measurement, ensure your laptop’s lid is completely closed.

Width Measurement

Aside from your laptop’s screen size and shape, it would be best if you also considered its breadth to get a notion of its entire form factor. Unlike the screen size measurement, the width dimension comprises the display bezels and the outside frame. Insert a measurement tape vertically or left to right on top of your laptop to determine its width.

Depth Measurement

It would be best if you also looked at the depth and length of your laptop to determine its form factor. The depth measurement, like the width unit of measure, includes the screen bezels and indicates the exact sleek design of your laptop. To measure the depth, position your measurements tape horizontally or from top to bottom of your laptop.
