Charlie Delray Hi there Charlie and thanks. I can see the discrepancy. The difference between 72/96 is minimal, but I will change for consistency sake in the article. For retina displays 96 or even 150 ppi can often look a little crisper than 72, but the higher the resolution the bigger the file size, so it’s usually just a matter of balancing the highest possible quality with a manageable file size.

Appreciate it and if you need any help with anything, just let me know.

Best,
Mike
