iCloud & iCloud Photos · iCloud storage space and plans
Can I share my iCloud storage with my family?
Short answer: Yes, with iCloud+ plans that support Family Sharing. Family members share the storage space, not each other's files, which stay private. Set it up in System Settings → Family; remember one person can fill the shared pool for everyone.
Yes, on iCloud+ plans that support it, through Family Sharing. Each person keeps their own private iCloud — family members share the space, not each other's photos or files. Set it up in System Settings → Family, then share iCloud+ from there.
Everyone draws from the same pool, so one member's photos or backups can fill it for all. The storage list in iCloud settings shows how much each person uses.
