How do I add more space to Gmail?

Last reviewed: September 27, 2026 · Markdown version

You cannot add space to Gmail on its own. Gmail uses your Google account's storage, which it shares with Drive and Photos, so the choice is to make the whole account bigger or to free part of what it already has. Google's storage page puts both in two sentences: each account "includes up to 15 GB of storage, which is shared across Gmail, Google Drive, and Google Photos", and "To add to your storage quota, you can purchase a Google One membership, where available" (How your Google storage works, read 27 September 2026).

Adding space: what Google offers, by account type

Google's buying page lists three routes, each adding to the account as a whole (Buy more Google storage, read 27 September 2026):

Personal account: Google One. The steps: one.google.com → Upgrade → choose the storage limit → Subscribe.
Workspace Individual: the page says it "comes with 1 TB of storage".
Work or school account: you cannot buy it yourself. "If you have a work or school account, you can't buy more storage for yourself"; the person who gave you the account can.

Three practical notes from that page. A new plan "may take up to 24 hours" to appear. A plan bought through another company has to be changed through that company. And "Buying Google storage is only available in some countries." Whether paying is worth it at all is its own question; prices vary by country, so we leave them to Google's pages.

Freeing space instead

Before you pay, check which product is filling the account. Google's cleanup page for Drive, Gmail and Photos starts with the folders people forget: Trash and Spam, because "Until you permanently clear items in these folders, they count against your storage limit". For Gmail its next tip is size, not age: "Find and delete one or two emails with very large attachments you no longer need" (Manage your storage in Drive, Gmail & Photos, read 27 September 2026). The search has:attachment larger:10M is Google's own example on that page. What usually takes the space.

Expect a delay. The same page asks you to "Allow time (up to 48–72 hours) for your storage to update after deleting multiple files at once".

One cleanup tool that does not use Trash

Google's storage manager has a cleanup mode on iPhone that appears only when you are over quota, reached through Clean up space or Manage storage in the Gmail, Drive or Photos app. Read its fine print before you swipe: "For Google Drive and Gmail: Items deleted are permanently deleted and can't be recovered." Photos items go to Trash; Gmail and Drive items do not (the How your Google storage works page). That is the opposite of deleting inside Gmail itself, where "When you delete a message in Gmail, it's moved to Trash" and stays findable there for up to 30 days (Delete messages in Gmail, read 27 September 2026).

Where we fit

If the space is in Gmail, Adinand Email Cleaner lists your mail by sender with the size of each group, measured from Gmail's own per-message sizes, so the heavy senders are obvious. Its limits, plainly: it only works on the Gmail part of the 15 GB, so a quota filled by photos is out of its reach; and it moves mail to Gmail's Trash rather than deleting it, so the space will free up after Trash clears, or sooner if you empty Gmail's Trash yourself.
