Share iCloud+ Storage With Your Family

Updated July 2026 · 3 min read

If two people in one household are each paying for iCloud storage, one of them is wasting money. A single iCloud+ plan — 200 GB or larger shares best — covers up to six people through Family Sharing, with everyone's data kept completely separate.

Step 1: set up Family Sharing

  1. Open System Settings and click Family in the sidebar (on Ventura it appears as Family Sharing; you can also start from your name → Family Sharing).
  2. Click Set Up Family and follow the prompts — you become the family organiser.
  3. Invite up to five others by email or Messages. Each person joins with their own Apple Account; nobody shares a login.

Kids under 13 get accounts created inside the family by the organiser; everyone else accepts an invitation. Joining a family changes nothing about anyone's existing data, devices, or sign-ins — it just creates the umbrella that subscriptions and purchases can be shared under.

Step 2: share the iCloud+ plan

  1. In System SettingsFamily, click Subscriptions (or your name → Family SharingSubscriptions).
  2. Find iCloud+ and turn on sharing. If your plan is 200 GB or 2 TB+ it's shareable; a 50 GB plan is not — upgrade first via iCloudManageChange Storage Plan.
  3. Family members get a notification. When they accept, their own paid plan (if any) is cancelled by Apple at the end of its billing cycle — no double payment, nothing to remember.

Everyone in the family now draws from the same storage pool and gets the other iCloud+ perks — Private Relay, Hide My Email, HomeKit Secure Video — on their own account.

Privacy: what family members can and can't see

This is the question that stops most people, so to be clear: sharing storage shares capacity, not content. Each member's photos, files, messages, and backups stay in their own account, invisible to everyone else — including the organiser. What the organiser can see is how many gigabytes each person is using: System Settings → your name → iCloudManage shows a Family Usage breakdown by member, numbers only. Purchases are separate machinery: the organiser pays for family App Store purchases, and purchase sharing can be toggled independently of storage.

When someone outgrows the pool

A 200 GB plan dies fast once two people turn on iCloud Photos — one heavy photographer can consume it alone. Your options, in order of sense:

If the family already pays for Apple Music or TV+, check Apple One before upgrading storage alone: the Family bundle includes 200 GB shared, and Premier includes a shared 2 TB — often cheaper than the same services bought separately. One quirk to know: a person can only be in one family at a time, and the organiser role can't be transferred without dissolving and re-creating the family, so put the plan on the account of whoever manages the household's subscriptions long-term.

One plan, six people, zero fuss
