Find Large Emails in Gmail: Step-by-Step Guide

If your Gmail is running out of space, large emails with attachments are likely the main culprit. Gmail’s 15 GB free storage is shared with Google Drive and Photos, and once it’s full, you can’t send or receive emails. Instead of paying for extra storage, you can quickly free up space by finding and deleting large emails. Here’s how:

• Use Gmail’s search operators like larger:10M to locate emails over 10 MB.
• Combine operators for precise searches, e.g., has:attachment larger:5M older_than:1y to find old, attachment-heavy emails.
• Review flagged emails carefully, save important attachments elsewhere, and delete unnecessary ones.
• Empty your Trash folder to permanently free up space.

For a hands-off solution, tools like MailSweeper automate email cleanup, saving time and effort while helping you avoid storage fees. Whether you prefer manual methods or automation, these tips help keep your Gmail clutter-free.

Gmail Storage and Search Operators Explained

How Gmail Storage Works

Your Gmail account shares a 15 GB free storage quota with Google Drive and Google Photos across your entire Google account. Every email you receive or send, including those with attachments like photos or documents, counts toward this limit. Over time, these files can quietly pile up, taking up more space than you might realize.

Once you hit the 15 GB limit, Gmail stops accepting new emails, and uploads and backups across Google services are blocked. At that point, you have two options: clean up your storage or upgrade to a Google One plan, which starts at $1.99 per month for 100 GB. If you’re looking to avoid those monthly fees, deleting large emails can quickly free up space across all Google services.

One challenge here is that Gmail doesn’t show the exact size of each email in your inbox view. That’s where Gmail’s search operators come in handy - they help you track down and manage the emails that take up the most space.

Gmail Search Operators Overview

Gmail’s search operators are text commands that let you filter emails by size, attachments, and other criteria. Two of the most effective operators for identifying large emails are larger: and size:. For example, typing larger:10M in the search bar will display all emails larger than 10 MB, while size:5MB will locate emails equal to or larger than 5 MB.

You can make your searches even more precise by combining multiple operators. For instance:

• has:attachment larger:5M older_than:6m will find emails with attachments over 5 MB that are older than six months.
• filename:pdf will locate emails with PDF attachments.
• older_than:1y will pull up emails that are more than a year old.

Here’s a quick reference table for commonly used Gmail search operators:

Operator	Function	Example Usage	Best For
larger:	Finds emails larger than a specified size	larger:10M	Quickly filtering by size
size:	Finds emails equal to or larger than a size	size:5MB	Targeting specific sizes
has:attachment	Filters for emails with attachments	has:attachment	Locating attachment-heavy emails
filename:ext	Finds emails with specific attachment types	filename:pdf	Searching by file type
older_than:	Finds emails older than a specified time	older_than:1y	Cleaning up old emails

These operators are case-insensitive and can be combined for highly detailed searches. While they work on both the Gmail desktop interface and mobile app, performing bulk actions - like deleting multiple emails at once - is generally easier on a desktop.

How to find large emails and attachments in Gmail

Step-by-Step Guide to Find Large Emails in Gmail

Now that you're familiar with Gmail's search operators, let’s dive into how to locate those massive emails that are eating up your storage. Follow these steps to quickly identify and manage large emails using Gmail's built-in tools.

Using the 'larger:' and 'size:' Operators

One of the easiest ways to track down large emails is by using Gmail's size-based search operators. Here's how:

• Open Gmail and type larger:10M in the search bar. This will display all emails larger than 10 MB.
• The larger: operator works with both MB and KB (e.g., larger:20M for emails over 20 MB). If you're looking for emails within a specific size range, combine operators like larger:5M smaller:8M to narrow it down to emails between 5 MB and 8 MB.
• Alternatively, use the size: operator, which accepts sizes in bytes or MB (e.g., size:5MB) to find emails equal to or larger than the specified size.

While Gmail doesn’t let you sort results by size, these operators can quickly filter out emails that are taking up the most space.

Once you've identified large emails, you can refine your search further to focus on messages with hefty attachments.

Finding Emails with Attachments

Attachments are often the biggest culprits when it comes to storage issues. Use the has:attachment operator to zero in on these emails.

• Combine has:attachment with size-based operators to find large emails with attachments. For example, larger:5M has:attachment will show emails with attachments over 5 MB. This is especially helpful for spotting space-hogging files like videos, presentations, or images.
• Add the filename: operator to filter by specific file types. For instance, larger:10M has:attachment filename:pdf will locate PDF attachments over 10 MB. You can replace 'pdf' with other file extensions like jpg, mp4, or docx depending on what you're looking for.

Important Tip: Gmail's conversation view may only display the first large message in a thread when searching by size. To ensure you don’t miss anything, expand the entire thread to review all messages.

For even more precise results, you can combine multiple search operators.

Combining Operators for Advanced Searches

To refine your search further, combine multiple operators. This allows you to target emails based on size, date, sender, or attachment type. Here are some examples to get you started:

• larger:10M older_than:1y from:client@example.com: Finds emails larger than 10 MB, over a year old, from a specific sender.
• larger_than:5M smaller_than:8M has:attachment filename:pdf: Locates PDF attachments between 5 MB and 8 MB.
• has:attachment larger:5M older_than:6m: Identifies emails with attachments over 5 MB that are older than six months.

Remember, Gmail’s search operators are not case-sensitive, and there should be no spaces between an operator and its value.

Once you've run these searches, take a moment to review the results. Open individual emails to verify their content and attachments before deciding what to delete. This step ensures you don’t accidentally remove anything important while clearing up space.

How to Manage and Delete Large Emails

Once you've pinpointed the emails taking up the most space, it's time to carefully review them. This ensures you don’t accidentally delete anything important, like critical messages or attachments.

Reviewing and Selecting Large Emails

Start by going through each flagged email to determine its importance. Pay extra attention to emails that are starred, marked as important, or sitting in your primary inbox. Keep anything from key contacts or emails containing receipts, contracts, or ongoing project files.

On the flip side, promotional emails with large images, old newsletters packed with graphics, or outdated project files are usually safe to delete. If you come across an attachment you still need, save it to Google Drive before removing the email.

Gmail’s conversation view can be especially helpful here. A single email thread might have multiple large messages or attachments, so reviewing the entire thread can save time and effort.

Deleting Large Emails Safely

Here’s how to delete emails without worry: Use the checkboxes next to each email to select them, then click the trash icon to move them to the Trash folder.

But keep this in mind - deleted emails don’t immediately free up space. Gmail holds onto them in the Trash for 30 days before they’re permanently erased. If you need to reclaim storage right away, manually empty the Trash folder.

Before doing so, take a final look through the Trash. Double-check for any emails from important senders, critical attachments, or anything else you might regret losing. Once you’re certain only unnecessary emails remain, go to the Trash folder, click "Empty Trash now", and confirm. Keep in mind, this step is irreversible.

If you frequently deal with a large number of emails, consider setting up a regular cleanup routine - monthly or quarterly works well. This way, you can manage your inbox before it becomes overwhelming.

Manual Gmail Cleanup vs. MailSweeper

Still wondering if MailSweeper is worth it? Here’s a side-by-side comparison of manual cleanup versus automated cleanup with MailSweeper:

Feature	Manual Gmail Cleanup	MailSweeper Automated Cleanup
Time Required	High (hours/month)	Low (minutes/month)
Accuracy	Variable (user-dependent)	High (AI-driven, consistent)
Customization	Manual filters, limited	Advanced, AI-based preferences
Cost	Free (time cost)	One-time payment, no subscription
Risk of Error	Higher (manual deletion)	Lower (AI identifies patterns)
Frequency	User-initiated	Automated, periodic

For anyone who deals with a high volume of emails - especially those receiving 100+ messages daily - the value of automation becomes clear. Roughly 50% of daily emails are often low-priority or promotional, making manual management not just tedious but nearly impossible to keep up with. MailSweeper transforms this overwhelming task into a manageable, efficient process.

Conclusion: Making Gmail Storage Management Simple

Managing large emails in Gmail doesn’t have to feel like a chore. Gmail’s built-in search operators, such as larger:10M and has:attachment, make it easy to pinpoint those bulky emails without endlessly scrolling through your inbox.

Large emails can quickly eat into your 15 GB storage limit. By regularly using search operators to find emails over 5–10 MB, many users can reclaim several gigabytes of space in no time.

Whether you prefer rolling up your sleeves with manual searches or letting automation handle the heavy lifting, these strategies make it easier to manage Gmail storage. High-volume users may lean toward automation, while occasional manual cleanups can work well for smaller inboxes.
