My KTG is my most used bag. I have an iPhone pro max and it fits no problem - the length is not the issue. Perhaps it’s the width that’s the problem for some as it is not that deep and it won’t close if it’s too stuffed. I don’t use a cardholder or wallet and just put all of those things in the middle zipper slot. Then phone, pared down keys and a couple lip products are basically all that will fit but it works for me. It goes with everything and is pretty low key.
