If you want the smallest possible display, you want the 12-inch MacBook.If you want a DCI-P3 wide gamut display, you want a new MacBook Pro, from 2016 or later.If you want a Retina display, you want the MacBook or MacBook Pro.The current 2017 MacBook Pro (as well as the 2016 models) also supports DCI-P3 wide color gamut and other advanced technologies that provide brighter reds, deeper greens, and blacker blacks. They're Retina, like the MacBook, so at normal viewing distance you shouldn't see any obvious pixels. MacBook Pro comes in two sizes: The 13-inch model has a 2560x1600 16:10 display at 227 ppi, and the 15-inch model has a 2880x1800 16:10 display at 220 ppi. That means, from a normal viewing distance, you can still see the individual pixels on the screen, almost like you're looking through a screen door. That's standard definition, not a high-definition Retina display like the MacBook and MacBook Pro. MacBook Air now only comes in 13 inches (the 11-inch model was discontinued in 2016). That's what Apple terms a "Retina" display, meaning that at normal viewing distance, you can't really see the pixels anymore, and it appears like you're looking at a photo or out a window. That houses a 2304x1440 16:10 aspect ratio display at 226 pixels-per-inch (ppi). MacBook is currently offered in one size, 12 inches diagonal.

The bigger the display, the more you have to carry, but the more you can see. The display is your window into apps and the internet.
