Box Storage Limit: Space and File Size Caps by Plan (2026)
Box sets two separate limits: total storage and maximum file size per upload. The free Individual plan gives you 10 GB of storage with a small per-file cap, Personal Pro offers 100 GB with up to a 5 GB file size limit, and paid Business plans provide large or effectively unlimited storage with per-file caps that climb by tier, up to 150 GB per file on the top plan. As of 2026 these are the published figures, but Box adjusts plans over time, so confirm on the Box pricing page before committing.
The Limits at a Glance
Individual (Free)
- Storage: 10 GB
- File size: small per-file cap (varies; historically in the hundreds of MB — check current plan details)
Personal Pro
- Storage: 100 GB
- File size: up to 5 GB per file
Business Starter
- Storage: 100 GB
- File size: up to 2 GB per file
Business / Business Plus
- Storage: large or effectively unlimited
- File size: up to 5 GB (Business) / 15 GB (Business Plus) per file
Enterprise / Enterprise Plus
- Storage: effectively unlimited
- File size: up to 50 GB (Enterprise) / 150 GB (Enterprise Plus) per file
Storage and file-size caps are separate and change periodically; treat these as the 2026 baseline and verify on Box’s pricing page.
Storage Space vs. File Size Are Two Different Caps
The number that trips people up is not total storage, it is the per-file upload limit. Even on a plan with generous or unlimited storage, a single file that exceeds your plan’s file-size cap will fail to upload. A Business account with plenty of space can still reject a 20 GB video export if its per-file cap is 5 GB.
This is exactly the reverse of the more common problem on other services, where you run out of total space long before any single file is too big. On Box, the file-size cap is the one worth checking first when an upload fails, because it climbs steeply by plan tier rather than by how much room you have left.
How the File-Size Cap Scales by Plan
The per-file limit is one of the clearest reasons to move up a Box tier. Free and lower plans are designed around everyday documents, so their caps sit low. As you climb into Business Plus, Enterprise, and Enterprise Plus, the ceiling rises sharply — toward 15 GB, 50 GB, and 150 GB per file respectively — precisely because those plans target teams handling large media, engineering builds, and design assets.
If your only reason to upgrade is one occasional oversized file, it is often cheaper to split or compress the file than to jump a tier. But teams that routinely move multi-gigabyte assets should size their plan around the largest single file they expect to upload, not around total storage.
What Happens When You Reach a Limit
Hit your storage cap and Box stops accepting new uploads until you delete files or upgrade; your existing files stay fully accessible. Note that deleted files may sit in Trash and continue to count against your quota until Trash is emptied or auto-purges.
Exceed the per-file cap and that specific upload is rejected outright, regardless of how much total space you have. The fix is a bigger plan, or splitting the file — not freeing up storage.
Troubleshooting
Why won’t my file upload to Box even though I have space left?
You are almost certainly over your plan’s per-file size cap, which is separate from total storage. A file larger than the cap fails even on an account with plenty of room.
How much free storage does Box give?
The free Individual plan includes 10 GB of storage. The per-file upload cap on the free plan is modest, so check the current figure on Box’s pricing page before uploading large files.
Is Box Business storage really unlimited?
Business-tier plans advertise large or effectively unlimited storage, but each still enforces a per-file size cap that varies by tier. “Unlimited” refers to total space, not file size.
Do deleted files still count against my Box quota?
They can. Files in Trash may continue to occupy your quota until Trash is emptied or the retention window expires. Empty Trash to reclaim space immediately.
How do I raise my Box file size limit?
Upgrade to a higher plan. The per-file cap rises with each tier, reaching up to 150 GB per file on Enterprise Plus.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
