Compared with 14 inch and 15 inch, it will be slightly smaller, but it also means that it is more portable and the overall weight of the fuselage will be lighter. Bare metal is only 1.38kg, while 15 inch is 17. 1kg, which is less than the weight of a bottle of mineral water. 14 inch is a better choice if you often need to take out your notebook.
But 15 inch has a large screen and a small keyboard. For digital input, the horizontal numeric keys on the keyboard are obviously not as efficient as the small numeric keyboard. Configuration and price will also be higher. I usually use PS, AI and PR. There are many softwares, so it is really convenient to use a big screen. If you want to play games every day, the big screen will be better.
In short, the size of 14 inch and 15.6 inch are different, that is, the price and weight are different. If the budget is enough, regardless of the weight difference, it is best to choose 15.6.
15-inch notebook screen, high-resolution screen, with the resolution of 1920* 1080, so that when watching some high-definition movies, it will really be uncompressed and the game can be adjusted to a higher resolution. Of course, the higher the resolution, the better the graphics card, otherwise it will get stuck. 15 inch notebook screen is larger, so the keyboard area will be larger, and generally a small keyboard area will be increased.
