15.6"

The 15.6-inch form factor is the most common. This category contains everything from entry-level devices to the most premium models. It’s a size that’s sufficiently large to hold high-end processors and graphics cards, as well as their corresponding cooling solutions. Many users perceive laptops in this size category as a good compromise between display size and portability.

Also, 15.6″ displays, keyboards and other parts in the appropriate sizes are available in large volumes, which helps keeps the manufacturing costs down.

In the past few years, 15.6-inch laptops have actually become physically smaller, since many manufacturers use smaller bezels around the display. However, it’s worth noting that more compact form factors will increase the need for efficient cooling.
