Gmail free storage: how to stay under 15 GB for good
15 GB sounds like a lot for email — until the "almost out of storage" banner shows up. The good news: most free Gmail accounts aren't full of mail people want to keep. They're full of things nobody would miss. Here's what really eats the free quota, and a short routine that keeps you off a paid plan.
How much free storage does Gmail give you?
Every free Google Account gets 15 GB. That space isn't Gmail's alone: it is one pool shared by Gmail, Google Drive and Google Photos. A phone that backs up photos in original quality can fill your inbox's space without you ever opening Gmail. (How the shared quota works →)
Inside Gmail, everything counts: the text of every message, every attachment, what you've sent, what you've archived, and what's sitting in Spam and Trash.
Four myths that waste your cleanup time
| Myth | Reality |
|---|---|
| "Archiving frees space." | Archived mail moves to All Mail and still counts, byte for byte. |
| "Getting to Inbox Zero will fix it." | A tidy inbox can sit on 14 GB of archived mail. Storage is about size, not message count. |
| "I deleted it, so the space is back." | Deleted mail sits in Trash for 30 days and keeps counting. Empty Trash to reclaim it now. |
| "My Sent folder is small." | Every photo, scan and PDF you ever sent is stored again in Sent — often the biggest surprise in the account. |
What actually fills a free Gmail account
- Attachments, sent and received. Phone photos, scanned documents, slide decks. A handful of 20 MB threads outweighs years of plain text.
- The newsletter long tail. Each one is small, but a daily newsletter with images is thousands of messages over a few years. 10,000 messages at 80 KB is already 800 MB.
- Notifications you never read. Order confirmations, social alerts, app receipts — individually tiny, collectively heavy.
- Old years. Mail from a job or a project that ended a decade ago, still stored in full.
Gmail has no "sort by size" and no per-sender totals, so you can't see which of these is your problem. That's the gap MailBalance fills: it ranks your mail by size — per message, per sender, per mailing list and per year — for free, inside your browser.
A 15-minute routine to stay on the free plan
- Check where you stand. Open one.google.com/storage to see how the 15 GB splits between Gmail, Drive and Photos.
- Take the big wins. Search
larger:10M, thenlarger:5M, and delete what you don't need. - Clear your own attachments. Search
in:sent has:attachment larger:5M— the originals are usually still on your computer or in Drive. - Drop old promotions. Search
category:promotions older_than:1y, select all matching conversations, delete. - Empty Spam and Trash. Until you do, nothing you deleted is actually freed.
Repeat every few months. Storage refills slowly, so a quarterly pass is usually enough to never hit the wall. For the complete list of searches, see how to free up Gmail storage fast.
Can you get more Gmail storage for free?
Not from Google: extra space is sold through Google One. So the free options are about reclaiming, not adding:
- Reclaim Gmail space — usually the fastest, because bulk mail is pure dead weight.
- Reclaim Drive and Photos space — it's the same pool. Our sibling tool DriveBalance does for Drive what MailBalance does for Gmail.
- Keep newsletters out — unsubscribe or filter them before they pile up (how to delete everything from one sender →).
Weighing a paid plan instead? Read should you pay for Google One, or clean up first.

Questions
How much free storage does Gmail have?
15 GB per Google Account, shared between Gmail, Drive and Photos. There is no separate allowance just for email.
Does archiving emails free up storage?
No. Archiving only hides a message from the inbox. Only deleting it — and emptying Trash — frees the space.
Do Trash and Spam count against my storage?
Yes, until messages are permanently deleted. Gmail does that automatically after 30 days; emptying both does it now.
Can I get more Gmail storage for free?
Not from Google. The free way is to reclaim space — in Gmail, and in Drive and Photos, which share the same 15 GB.
