When you are looking for a laptop sleeve or a computer bag suitable for your laptop, it is essential to understand the dimensions of your electronic device. Knowing the exact dimensions of your laptop will help you avoid making a mistake in choosing the size of your sleeve or bag.

Laptops are not measured in centimeters but in inches. Therefore, it's important to understand the difference between the two (inches vs cm). Indeed, knowing the equivalents in centimeters can be useful to facilitate your understanding. Let's explore the different parameters to understand the dimensions of a 15-inch laptop and convert them into centimeters. This will allow you to find the ideal computer bag to protect your Laptop precisely.

How many centimeters in an inch?

Before diving into the specific dimensions of a 15-inch laptop, let's quickly recall the difference between inches and centimeters. Inches, also called "inch", are a unit of measurement commonly used in Anglo-Saxon countries, especially in the field of technology, to describe the size of computer screens and electronic devices (TV, smartphone, tablet, etc.).

Centimeters, on the other hand, are a unit of measurement in the metric system more widely used in the rest of the world. We use cm in everyday life, to measure all possible and imaginable things.

For your personal knowledge, note that one inch is equivalent to about 2.54 centimeters. Here is a table of conversion measurements from inches to cm." :

How to Calculate Inch

Now that we know how to convert inches to cm, it is important to understand how they are calculated. Inches are based on the diagonal, that is, the distance between two opposite corners of the screen.

For example, when a laptop is described as being 15 inches, it means that the diagonal of the screen measures approximately 15 inches from one corner to the other, or 38.1 cm if referring to the table above.

It is necessary to note that the exact dimensions of a 15-inch screen may vary from one model and brand to another (HP, Acer, Asus, Toshiba, etc.), but the measurement of the diagonal remains the main reference for determining the screen size.
