How Google storage is shared between Drive, Photos and Gmail
There is no separate "Drive space" and "Gmail space". Your Google Account has one storage quota, and Drive, Photos and Gmail all draw from it. That's why deleting old emails can free up room to back up more photos.
What counts against your storage
| Product | Counts against your quota | Usually free (doesn't count) |
|---|---|---|
| Drive | Uploaded files, PDFs, videos, ZIPs; anything in the trash for up to 30 days | Google Docs / Sheets / Slides created before 1 Jun 2021; files shared with you (owned by others) |
| Photos | Photos & videos backed up at "Original" or "Storage saver" quality | Photos backed up in the old "High quality" mode before 1 Jun 2021 |
| Gmail | All messages and their attachments, including Spam and Trash | — |
Emails in Spam and Trash still count against your storage until they're permanently deleted, and Gmail only auto-purges them after 30 days. A single old newsletter with a big attachment, multiplied over years, is a very common reason accounts fill up.
What happens when you run out
- You can no longer receive new email in Gmail (senders get a bounce).
- You can't back up new photos or videos to Google Photos.
- You can't create or save files in Drive, Docs, Sheets or Slides.
- Existing content stays safe and readable — nothing is deleted automatically.
Frequently asked questions
Is Google storage really shared across all three?
Yes. Drive, Photos and Gmail share one quota — 15 GB on a free account. Clearing space in one frees it for all.
How much free storage do I get?
15 GB free. Google One raises it to 100 GB, 200 GB, 2 TB and up.
Do shared files count against my storage?
No — files owned by someone else and shared with you count against their quota, not yours.
