How much storage is required for iOS 18?

My phone has a total of 64 GB of storage.

I’ve offloaded nearly all my apps and also deleted a couple. My phone originally said the upgrade was 7.08 GB, and so did the 17.7 update, so I figured just skip the 17.7 and do the iOS 18, so I freed up the necessary space for 7.08 GB. It then said I had enough space for the 17.7, but not the 18. I decided to just do the 17.7 and then see if I could try to get iOS 18 after the update, and when my phone finished updating to 17.7, I checked the “upgrade to iOS 18” and the storage it said it needed CHANGED TO 14.71 GB. UM WHY????

Also, the update for 17.7 on my mother’s (iPhone 14 with 128 GB) and sister’s (iPhone 12 with 64 GB, same as mine) phones said the update was about 716 MB while the iOS 18 was about 4 GB.

My main question is why do both of those updates on my phone require more storage than theirs if it is the SAME UPDATE ROLLED OUT TO EVERYONE?? Even if it has something to do with all the stuff I have on my phone, it is all offloaded now, so …??? And, even regardless of THAT too, I don’t understand why it says iOS 18 is literally nearly 15 GB like what….????

My storage is now 53.87 GB and I literally have no idea what else to offload/delete.

Hey, Problem solved after reading this thread. Weeks ago I updated to 17.7 and it offered me 18. I have an iPhone 11 , 64 GB. But I had 6.71GB of free space and it said I needed 13.7. For weeks I have been trying to figure out what to do and it sounded like my problem may be even worse than I tought after reading of the issues that many here were having,

But I just did the update using iTunes and my PC and I only lost 1 GB or so of space.., It was easy as pie. I never use iTunes but had it on my Windows 10 desktop, I updated the program, plugged in the USB and it offered me the update, It may have taken half an hour and all the while my phone was still showing that it would not update while on Itunes I could see that it was downloading then preparing and then installing. So thanks for the help and now I will take a quick look at iOS 18.1. My wife is bugging me to go to bed as it is 3:23 am
