Hi, casperbiemans Great question! Before I get into it, here's a really quick guide on exporting: Learn how to export production-ready assets from Adobe Experience Design as PNG, SVG, and PDF files. To answer your question, however: iOS has a concept of a virtual point. I found this great explanation of the difference between pixels and points here: http://blog.fluidui.com/designing-for-mobile-101-pixels-points-and-resolutions/ It's a great read, and I think really valuable for understanding what I'm going to say next. When XD outputs for iOS, it's going to output at 1x, 2x, and 3x resolutions. The 1x will be for your older screen sizes, 2x will be for up to iPhone 5s, and 3x will be for your newer, higher resolution screens. The actual size it outputs, though, is dependent on how you designed. If you design with the default artboards we have (which are, if you notice, half the size of what you're used to), you can leave your export settings to "designed at 1x," and it will export at 1 virtual point = 1px (aka 1x), 1 virtual point = 2px (aka 2x), and 1 virtual point = 3px (aka 3x). However, if you duplicate the artboard size you're used to in Photoshop, you should select "designed at 2x" in the export panel in XD. This will output 1 virtual point = 1/2 px (aka 1x), 1 virtual point = 1px (aka 2x), and 1 virtual point = 1.5x (aka 3x). You'll get the same exact pixel size in your output in both cases, but in the latter, your artboards in XD are much larger. Hopefully it all makes more sense to you now! Let me know if you have additional questions and I can try to answer. Thanks, -Elaine
