Family iCloud Storage Full? See Who's Using It

You pay for one iCloud plan for the whole family, and now every phone in the house says iCloud storage is full. Your teenager says it isn't them. Your partner says it isn't them. A shared plan is one pool, so one person can fill it for everyone. To see who: on the phone of the person who shares the plan, go to Settings > [your name] > iCloud > Storage > Family Usage. Then that person clears space on their own iPhone, usually an old backup, videos, or big Messages attachments, because nobody else can do it for them. If everyone is already lean, upgrade the plan.

Apple's family iCloud+ page explains the alert: "If your Family Sharing group is low on iCloud storage, all members get a notification." So getting the message doesn't mean you caused it.

Step 1: find out who is using the space

1. On the iPhone of the person who shares the iCloud+ plan (usually the family organizer), open Settings and tap your name at the top.
2. Tap iCloud, then Storage. On some iOS versions it's called Manage Account Storage.
3. Tap Family Usage. You'll see how much of the plan each family member is using.

You see amounts, not content. Apple says each member keeps their own Apple Account, so "your photos, documents, and other information stay private, even though you're sharing access." That's good for privacy. It also means the organizer can't open a kid's library and delete the 40 GB of slime videos. The cleanup has to happen on that person's account.

Step 2: clear the space on that person's iPhone

Sit down with the phone of whoever is using the most. Start with the things that free the most for the least effort. Apple's Manage your iCloud storage page covers each one.

1. Let iCloud suggest things first

On iOS 17 or later, go to Settings > [their name] > iCloud > Recommended for You. It points to old backups, large files and photos they might not need. If it shows nothing useful, carry on below.

2. Delete backups of phones nobody uses

This is the usual surprise. Last year's iPhone was traded in or handed down, but its iCloud backup is still sitting there. Go to Settings > [their name] > iCloud > Storage > Backups, tap the old device, then Turn Off and Delete from iCloud. Apple keeps backups for 180 days after a device stops backing up, so an old one can stick around for months. Make sure it really is an old device, not the iPhone in their hand. While you're there, look at the current phone's backup and turn off apps that don't need backing up.

3. Look at their photos and videos

With iCloud Photos on, the library is usually the biggest thing on the account, and videos make up most of it. Deleting a photo on the iPhone deletes it from iCloud and from their other devices, so back up anything that matters first. Good places to start: large videos, duplicates, screen recordings and bursts.

One thing that surprises people: Apple says items in Recently Deleted don't count toward iCloud storage, so deleted photos stop using iCloud space straight away. (Emptying Recently Deleted still matters for space on the phone itself.)

If the space is in their photo library, Phone Diet finds duplicates, similar shots and the largest videos, including photos that are only in iCloud. The scan is free.

4. Check Messages

If Messages in iCloud is on, every video sent to the family group chat is stored there too. In Settings > General > iPhone Storage > Messages, the Review Large Attachments list shows the biggest ones. With Messages in iCloud on, deleting them on one device removes them everywhere. Our guide to deleting old text messages covers the Keep Messages setting too.

5. On iOS 27: shared albums and the Shared Library

This one is new. In iOS 27, Apple says photos added to a shared album count toward the storage of the person who created the album (older-style albums made on iOS 26 or earlier and not upgraded don't count), and a Shared Library counts toward the storage of whoever created the library. If one parent made the "Kids 2026" shared album and everyone keeps adding to it, it all lands on that parent's account. For holiday albums, a temporary album that expires is the way around this, as we explain in getting everyone's Thanksgiving photos in one album. Be careful deleting from a Shared Library: it's removed for everyone who shares it.

6. iCloud Drive and Mail

In Settings > [their name] > iCloud > Storage, look at the list of apps by size. A forgotten iCloud Drive folder full of school project videos, or years of iCloud Mail attachments, can be large too.

The kids' phones

Children's phones are often the biggest users and the hardest to fix, because the content is theirs. There isn't a setting that lets a parent delete a child's photos from another phone. Sit down with them, have them pick what goes, and show them where Family Usage is so they can see their own number. Turning off the backup of a game that keeps its progress online is an easy win.

Step 3: if it's still full, upgrade (or split the plan)

Sometimes nobody is wasteful and five people's photos just don't fit. Only the organizer or the family member who bought the plan can buy more storage, up to 12 TB. Apple's current iCloud+ plans page lists sharing with up to five other family members on every tier, including 50 GB. US prices per month:

• 50 GB: $0.99
• 200 GB: $2.99
• 2 TB: $9.99
• 6 TB: $29.99
• 12 TB: $59.99

A member who wants more room for themselves can keep their own iCloud+ plan instead of the shared one. Apple says they can't use both at the same time. Before you pick a size, do Step 2 first. Otherwise you size the plan to fit the junk and pay for it every month. Our iCloud storage full guide walks through choosing the tier.

What happens if you leave it full

Apple lists what stops working: devices stop backing up to iCloud, new photos and videos stop uploading to iCloud Photos, iCloud Drive stops staying up to date, and nobody can send or receive email at an iCloud address. The backup is the dangerous one. A phone that hasn't backed up in two months is a phone whose last two months of photos exist in one place.

What Phone Diet can and can't do here

Full disclosure: we make Phone Diet. It works on the photo library of the iPhone it's installed on, under that person's Apple Account. It can't see your family's storage, can't touch anyone else's account, and can't delete iCloud backups, Messages or iCloud Drive files. If Family Usage shows the space is an old backup, you don't need any app: Step 2 in Settings is the whole fix.

Where it helps is the photo library. It scans for duplicates, near-identical shots, screenshots and the largest videos, including photos stored only in iCloud. With iCloud Photos on, deleting them frees iCloud space too. Items you delete are kept in the app's Recover area for a while so you can undo. One caution: if the phone uses an iCloud Shared Library, a duplicate you delete there is removed for everyone who shares it.

Questions people ask

How do I see who is using our family iCloud storage?

On the phone of the person who shares the plan: Settings > [your name] > iCloud > Storage > Family Usage. It shows each member's usage, not their content.

Why did everyone get the storage full message?

The shared plan is one pool. Apple sends the low-storage notification to all members, whoever filled it.

Can the organizer delete someone else's photos or backups?

No. Each person's content is private to their Apple Account, so they clear it on their own device. The organizer can upgrade the plan instead.

Can you share the 50 GB plan?

Yes. Apple's current plans page lists family sharing on every tier, 50 GB included.

What if we leave it full?

iCloud backups stop, new photos stop uploading, iCloud Drive stops syncing and iCloud email stops working until there's space again.
