When designing for desktop or web, you can either size your screens for a specific target resolution or use InVision to make your screens suitable for a variety of resolutions. To learn more, check out this article: How does the zoom/scroll feature behave?
If designing for a target resolution, there are two resources that can be helpful:
Adjust your screen dimensions to account for the status bar if necessary. For more information, read the section "Including the status bar in iOS" below.
Remember, mobile prototypes can scroll, so the screen heights listed on these sites are usually minimum heights for your designs.
When deciding what size screen to use, you should note that particularly large screens may appear blurry when viewed in Safari on iOS. For more information, read this article: Why are my images in iOS blurry?

InVision will overlay a status bar on your designs for you, so including it in your design is up to you.
If you don't want to include space for the status bar in your designs:
Navigate to your prototype and click to view a specific screen.
At the bottom of the page, click the configuration icon ().
Check the box My design starts below the status bar.
