When you sign up for iCloud, you automatically get 5GB of free storage for your iOS backups, photos, videos, documents, and apps. When you turn on iCloud Photo Library, the Photos app lets you know if you need more space to upload your library.
You can increase your iCloud storage by choosing a new monthly plan or by trying one of the options below. iCloud storage plans start at 50GB for $0.99 a month and go up to 2TB for $19.99 a month.
