Free Up Storage Space in Gmail: Full Guide
To free up storage space in Gmail, you need to delete or archive large emails and attachments, then empty the Trash and Spam folders. This guide walks you through the exact steps, explains how Gmail storage works, and shows you how to avoid hitting the limit again.
How Gmail Storage Works
Gmail storage is shared across three Google products: Gmail, Google Drive, and Google Photos. Every email you keep, every file in Drive, and every photo or video backed up in original quality counts against the same 15 GB free quota. This means a 500 MB video in Drive reduces the space available for your emails just as much as a 500 MB attachment in your inbox.
When your storage is full, you cannot send or receive new emails. Incoming messages bounce back to the sender with a notice that your mailbox is full, and you cannot attach files to outgoing mail. Google also stops processing new photos in Google Photos until you free up space.
Find What Is Taking Up Space
Before deleting anything, identify the largest culprits. Gmail has a built-in search operator that sorts emails by size. In the search bar, type:
- size:5MB – shows emails larger than 5 MB
- size:10MB – shows emails larger than 10 MB
- has:attachment – shows all emails with any attachment
- larger:20M – same as size:20M, shows emails over 20 MB
You can combine these with other operators, such as from:newsletter or before:2020/01/01, to narrow down results. For a visual breakdown, open Google One storage manager – it shows a pie chart of what is using space across Gmail, Drive, and Photos.
Delete Large Emails and Attachments
Once you have a list of large emails, you can delete them in bulk. Here is the step-by-step process:
- In Gmail, type size:10MB in the search bar and press Enter.
- Click the checkbox at the top-left to select all emails on the current page. If there are more than one page, Gmail shows a banner: “Select all conversations that match this search.� Click that to select every matching email.
- Click the trash can icon to delete them. This moves them to Trash.
- Go to the Trash folder (left sidebar, under “More�). Click Empty Trash now at the top. This permanently deletes them and immediately frees space.
Repeat this with size:5MB and size:1MB to catch smaller attachments. Also check the Spam folder – spam emails with attachments still count against your quota. Empty Spam the same way.
Use Google Drive to Store Attachments
If you want to keep emails but remove the attachment from your quota, you can save the attachment to Google Drive and then remove it from the email. However, this only works if you are willing to delete the original email. The attachment in Drive still counts against your storage, but you can organize it separately. A better approach is to download the attachment to your computer or an external drive, then delete the email. This moves the data off Google’s servers entirely.
Alternative: Archive Instead of Delete
Archiving removes emails from your inbox but keeps them in “All Mail.� It does not free up any storage space. Archiving is useful for decluttering your inbox view, but if your goal is to free space, you must delete and then empty Trash. Many users archive emails thinking they are saving space – they are not.
Prevent Future Storage Problems
Once you have freed up space, adopt habits to avoid hitting the limit again:
- Unsubscribe from newsletters that send large images or PDF attachments.
- Set up a filter to automatically delete or label emails from certain senders after a period.
- Use Google Photos “Storage saver� quality instead of original quality – this stops counting photos toward your quota.
- Regularly check your storage usage at one.google.com/storage.
- Consider buying more storage if you genuinely need more space – Google One plans start at 100 GB.
Common Mistakes and Misconceptions
One common mistake is deleting emails but not emptying Trash. Deleted emails stay in Trash for 30 days and still count toward your quota during that time. You must empty Trash manually to free space immediately.
Another misconception is that “All Mail� is a separate folder that uses extra space. It is actually the same emails as your inbox, just without the “Inbox� label. Deleting from All Mail is the same as deleting from anywhere else.
Also, be careful with the “Select all� feature – if you have hundreds of large emails, deleting them all at once is fine, but you might accidentally delete important ones. Use the search operators to filter by date or sender first.
Frequently Asked Questions
How do I check how much storage I have left in Gmail?
Scroll to the bottom of your Gmail inbox. You will see a bar that says “X GB of 15 GB used.� Click it to open the full storage manager. You can also go to one.google.com/storage for a detailed breakdown.
Does deleting an email free up space immediately?
No. Deleting moves the email to Trash, where it still counts against your quota. You must open Trash and click “Empty Trash now� to permanently remove it and free space instantly. Otherwise, it will be automatically purged after 30 days.
What is the fastest way to free up 1 GB in Gmail?
Search for size:10MB, select all, delete, then empty Trash. Repeat with size:5MB. Large video or PDF attachments are usually the biggest space hogs. This method typically frees the most space in the least time.
Will archiving emails help free up storage?
No. Archiving only removes the email from your inbox view. The email and its attachments still exist in “All Mail� and count toward your storage quota. Only deletion (and emptying Trash) frees space.
Do emails in Spam count toward my storage?
Yes. Spam emails, including any attachments, count against your quota until they are automatically deleted after 30 days. You can manually empty Spam by clicking “Delete all spam messages� at the top of the Spam folder.
Can I buy more storage instead of deleting?
Yes. Google One offers paid plans that increase your total storage across Gmail, Drive, and Photos. The free tier is 15 GB; paid plans start at 100 GB. Buying more does not clean up your inbox, but it gives you room to keep everything.
