Is the iphone 6 real size, 375×667px or 750×1334px(screen)?

Question

iPhone

In all mockups in all portfolios, it is 750 × 1334px, but this is a 2x retina i.e. its actual view is 375×667px? Why does everyone throw away shovels and how to show the customer in real size or in full pixels. so that there are no unnecessary questions about the scale of Ui-elements?

Answer 1

The iPhone 6 screen size is 750×1334 px.
For advertising teasers, it really should be reduced, for example, by half.
And when we show screenshots, mockups, etc. to the customer/programmer/coder, it’s only hardcore, only pixel for pixel.
