title: Why does iPhone 6 use @2x image assets?
body: <p><em>iPhone 6 plus</em> uses <strong>@3x</strong> image assets, but <em>iPhone 6</em> uses <strong>@2x</strong> image assets - just like <em>iPhone 4</em> and <em>iPhone 5</em> (<a href="https://stackoverflow.com/questions/25781422/image-resolution-for-new-iphone-6-and-6-3x-support-added">Image resolution for new iPhone 6 and 6+, @3x support added?</a>).</p>
  
  <p><em>iPhone 5</em>, <em>iPhone 5C</em> and <em>iPhone 5S</em> have the screen resolution <strong>640x1136</strong>. The screen resolution of <em>iPhone 6</em> is <strong>750x1334</strong>.</p>
  
  <p>So <em>iPhone 6</em> will scale up images from <strong>640x1136</strong>? Is there any way to make graphics customised for <em>iPhone 6</em>'s slightly higher screen resolution?</p>
  
  <p><strong>Edit:</strong>
  I know that the PPI is the same. But say for example I want to have an image take up all available width on both iPhone 5 and iPhone 6. I create a 640x200 px image and name it my_image@2x.png. On the iPhone 6 it's going to be upscaled to 750 pixels width, no?</p>
