“iCloud Storage Almost Full”
What to Do About It

Nothing Is Broken. A Shelf Is Full.

iCloud is Apple's storage locker in the sky. Everyone with an Apple Account gets 5 GB of it free — that number hasn't changed in a very long time — and your iPhone backup, your photo library, your iCloud Drive files and your @icloud.com email all share it. Five gigabytes was generous when phone cameras made small pictures. Today a single minute of iPhone video can run hundreds of megabytes, and one full iPhone backup can eat the whole 5 GB by itself. You didn't do anything wrong. The free shelf was sized for a different decade.

The most important thing on this page is a distinction almost everybody gets tangled in: iCloud storage and your Mac's storage are two different closets. Filling one has nothing to do with filling the other, and buying more of one does not give you more of the other. If the message on your screen says “startup disk,” that's the Mac and you want a different guide. If it says “iCloud,” you're in the right place. Below is the order I work in on a house call — look first, clear the free wins, then price the fix only if you still need to.

Start Here: The One Screen That Answers Everything

1. Click the Apple menu in the top-left corner of the screen.
2. Choose System Settings.
3. Click your name (your Apple Account) at the very top of the sidebar on the left.
4. Click iCloud. The bar at the top shows how much of your storage you're using.
5. Click Manage for the itemized list — biggest space-eaters first. Click any item for detail.
6. On an iPhone or iPad it's the same numbers: Settings → your name → iCloud → Storage (older versions say Manage Account Storage). You can also sign in at iCloud.com from any computer.
7. Write down your top three before you delete anything or spend a dollar. Ten minutes of looking beats an hour of guessing.

iCloud Storage vs. Mac Storage — the Confusion Behind Most Calls

• Your Mac's storage is the drive inside the machine. The warning reads “Your startup disk is almost full.” You check it at System Settings → General → Storage. On modern Macs you can't buy more — it's soldered in.
• iCloud storage is space on Apple's servers, shared by every device signed into your Apple Account. The warning reads “iCloud Storage Almost Full.” You check it at System Settings → your name → iCloud. You can buy more, from about $1 to about $60 a month.
• Buying iCloud+ does not give your Mac more room. The one place they touch is “Store in iCloud,” which moves files off the drive and into iCloud — emptying one closet by filling the other.
• If it's the Mac that's full, read my “Startup Disk Almost Full” guide instead. If you want the full map of what lives where, that's my “iCloud vs. On-Mac Files” guide.

What Actually Counts Toward Your iCloud Storage

• Photos — your iCloud Photos library, full-size originals of every picture and video. Almost always the biggest slice, and video is the heavyweight.
• Backups — iCloud backups of your iPhone and iPad, including devices you no longer own. Usually second biggest.
• Documents — iCloud Drive files, plus Notes, Reminders, Health and third-party app data.
• Mail — only your @icloud.com (and @me.com, @mac.com) email. Gmail, Yahoo and AOL live on those companies' servers, not in your 5 GB.
• Messages — if Messages in iCloud is on, every conversation and every photo anyone ever texted you.
• Family — what your family members are using, if you share an iCloud+ plan.
• Newer wrinkle: starting with macOS Tahoe 26 and iOS 26, contact photos and posters count too. Small for most people, not nothing if you've given a picture to two hundred contacts.

What Doesn't Count — Stop Hunting in the Wrong Place

• Apps, music, movies, TV shows and books bought from Apple. They live in Apple's stores and download again free — none of them appear in Apple's list of storage categories.
• Apple Music you stream. Your subscription library isn't sitting in your 5 GB.
• Files that live only on your Mac. If you never put it in iCloud Drive, it's using the Mac's drive instead.
• Someone else's shared folder. Apple says if you're a participant in a folder shared with you in iCloud Drive, it doesn't count against your storage.
• Photos in a Shared Library you didn't create — those count toward whoever set it up.
• But these do count and surprise people: anything in Recently Deleted (30 days), backups of devices you sold years ago, texted photos and videos, voice memos, and Apple Watch health data.

The Free Cleanup, Biggest Wins First

1. Delete backups of devices you no longer own. System Settings → your name → iCloud → Manage → Backups. Select an old device, click remove, confirm. This is the single most common free win in the whole guide — and it's free, instant, and costs you nothing you'll ever want back. Read the device name twice: never delete the backup of the phone in your pocket, because that also switches its nightly backup off.
2. Empty Recently Deleted in Photos. Those pictures are still using your space for 30 days.
3. Hunt videos, not pictures. Screen recordings, long clips, the accidental four-minute video of somebody's pocket. Ten of those beat a thousand photos. Then check Duplicates in the Photos sidebar, and search “screenshots.”
4. Mail: delete, then Mailbox → Erase Deleted Items and choose your iCloud account. Do the same for junk. Recent iPhones and iCloud.com also offer iCloud Mail Cleanup for promotions and receipts in bulk.
5. Messages: open a big old conversation, click the info button, and delete the attachments.
6. iCloud Drive: in the Finder, sort by size, remove what you don't need, then empty Recently Deleted.
7. Wait ten minutes and look again — iCloud takes a while to recalculate. That pause is normal, not a freeze.

What More Storage Costs (U.S. prices, mid-2026)

• Free — 5 GB. Fine for one device and a modest photo library.
• iCloud+ 50 GB — about $0.99 a month (roughly $12 a year). The right answer for most single users: phone backup plus a reasonable photo library.
• iCloud+ 200 GB — about $2.99 a month. A couple, or one heavy photo-taker.
• iCloud+ 2 TB — about $9.99 a month. The household plan: big video libraries, Desktop and Documents in iCloud.
• iCloud+ 6 TB — about $29.99 and 12 TB — about $59.99 a month. Rare at home.
• Every paid plan also includes iCloud Private Relay, Hide My Email, Custom Email Domain and HomeKit Secure Video support — and can be shared with up to five other family members at no extra cost.
• Prices change and some states add tax. Apple publishes the current list at support.apple.com — search “iCloud+ plans and pricing.” If a price in an email doesn't match Apple's own page, believe Apple's page.

Upgrading, Downgrading, and Sharing With Family

• To upgrade on a Mac: Apple menu → System Settings → your name → iCloud → Upgrade to iCloud+ (or Manage Plan if you already pay). Takes about a minute and starts right away.
• To downgrade or cancel: same screen → Manage Plan → See All Plans (older macOS says Downgrade Options). Choosing the free 5 GB plan is how you stop paying entirely.
• Get under the new limit first. Apple's guidance is plain: remove or download content that exceeds the smaller plan before you switch. Go over and iCloud just stops syncing and backing up until you're under again — Apple doesn't delete anything.
• The change takes effect at the end of your billing period, not the instant you click. Partial refunds are available where the law requires, and Apple says to contact them within 14 days if you recently changed plans.
• One plan covers up to six people through Family Sharing — even the 50 GB one. Everyone draws from the same pool, and nobody can see anybody else's files. Shared storage is not shared access.
• Paying for Apple One and a separate iCloud+ plan? You're probably paying twice — Apple One already includes iCloud+.

The Part That Matters Most: iCloud Is Not a Backup

iCloud syncs. A backup keeps. Those are different jobs, and confusing them is how people lose photographs they can't get back. With iCloud Photos on, deleting a photo on your Mac deletes it from your iPhone, your iPad and iCloud.com at the same moment — because that's what “the same thing everywhere” means. And here's the trap almost nobody knows: if you're already over your storage limit, deleted photos skip Recently Deleted entirely and are gone immediately. That's Apple's own warning, and it's the best argument I know for spending a dollar a month rather than freeing up space by deleting family pictures in a hurry. Buying more iCloud storage doesn't give you a backup; it gives you a bigger sync. What I'd have in place: iCloud sized right so the phone backs up nightly, Time Machine to an external drive, and a second copy of irreplaceable photos somewhere that isn't your house or your Apple Account. My 3-2-1 Backup Plan and Photo Backup guides lay that out step by step.

The “Storage Full” Scam Emails — Calm Rules That Beat All of Them

• Because this is a real alert millions of people see, it's perfect cover. “Click here to claim 50 GB free.” “Your iCloud payment failed — update your billing.” “Your photos will be permanently deleted in 24 hours.” All fake.
• Apple does not delete your photos for being over your limit. Syncing pauses. That's all that happens.
• The real message appears on your device, in System Settings — not in an email with a link. Never manage storage or billing from a link. Go to System Settings → your name → iCloud yourself, every time.
• A pop-up shouting that your Mac is full of junk, with a phone number, is lying — a website cannot see your storage, and that number is never Apple's. Don't click anything inside it, not even the X: press Command + Q, or Command + Option + Esc and force quit the browser.
• Apple doesn't take gift cards for storage plans. That one's on Apple's own page.
• If something already got clicked: change your Apple Account password from a device you trust, turn on two-factor authentication, and tell one person the same day. Saying it out loud is how it loses its grip.

Why I wrote this

“iCloud Storage Almost Full” is one of the most common messages I get called about, and it's one of the least dangerous — but it nags until people either delete something they miss later or panic-buy the biggest plan on the list. Neither is necessary. Most of the folks I sit with are one checkbox away from calm, usually an old iPhone backup nobody needs. And the plan that fixes it for most households costs about twelve dollars a year, which I'd rather you know than guess at. I write these guides as printable handouts so the checklist can live next to the computer, and if you'd rather do it with company, that's a flat $99 visit with a 30-day follow-up included. — Bill
