What's the proper way to export an InDesign CC v15.1.2 file so that it accommodates iOS devices? Although I have my file size set to 250 x 300 pixels, when I export the file using 144 PPI (Retina Resolution) the file dimensions double to 500 x 600 pixels. What am I doing wrong?

Thanks!

If you want the exported JPEG to have a matching 250px x 300px dimensions set the export Resolution to 72ppi.

Yeah, but aren't Retina displays 144 PPI?

The display resolution depends on the device and its physical dimensions. Here’s an iPhone resolution chart:

Most HTML pages are responsive to the device, so in general you want a large enough pixel dimension so that when the image is fit into the available space it is sampled down.
