How to crop 4:5 using the Photos app

After the latest updates (iOS 13), I can't find a native to crop a vertical image to 4:5 — I need that to upload photos on Instagram.

What's the alternative?


If you choose the crop tool in the Photos app, and then tap the crop presets button at the top right (looks like solid rectangle in another rectangle), you get some presets: Original, Freeform, Square, 9:16, 8:10, 5:7, etc.

But you want 4:5?

Just use 8:10. 4:5 = 8:10, right?
