The Trello board limit on the Free plan is 10 boards per Workspace, as of Nov 2026, while Standard is listed with unlimited boards. Separately, every board has its own caps on objects such as open cards, lists and labels, which Trello's developer docs show with a warning point and a disable point.
There are two different questions hiding in this search. One is how many boards you can have. The other is how much a single board can hold. Trello answers them in different places, and mixing them up is how people end up surprised.
How many boards you get
Trello's plans page lists up to 10 boards per Workspace on the Free plan, as of Nov 2026, alongside unlimited cards and use by up to 10 collaborators per Workspace. The Standard plan is listed with unlimited boards, and the page says teams can create as many as they need.
The cap is per Workspace and it counts boards. So the way to stay under it on Free is to close or delete boards you've finished with. A freelancer with one board per client will feel it quickly, while a small team with a handful of long-running boards may never notice.
Attachments differ by plan too: Free allows 10MB per file and Standard lists 250MB per file.
How much one board can hold
| Item | Limit | Applies to |
|---|---|---|
| Boards per Workspace | Up to 10 | Free plan (as of Nov 2026) |
| Boards per Workspace | Unlimited | Standard plan and above as listed |
| Open cards per board | 5000 (warns at 4500), example values | Any board, may vary |
| Open lists per board | 475 (warns at 450), example values | Any board, may vary |
| Labels per board | 950 (warns at 900), example values | Any board, may vary |
| Total members per board | 1520 (warns at 1440), example values | Any board, may vary |
Trello limits the number of objects, such as cards, checklists and stickers, that can exist on a board or a card. The developer docs show an example board with 5000 open cards, 2000000 total cards counting open and closed, 475 open lists, 950 labels, 15200 checklists and 1520 total members.
Those per-board numbers are examples, not promises
This is the part that gets misquoted. Trello Developer Docs say the example limits shown aren't the documented limits, and that limits may vary by board and by account. So treat 5000 open cards as a sense of scale, not a guarantee for your board. If you're building something that depends on the exact number, read your own board's limits rather than trusting a blog post, this one included.
What happens when a board fills up
Each limit has two thresholds. warnAt is the count where Trello's apps start warning users. disableAt is the count where the apps stop letting anyone add more objects of that kind. So you'll get a warning before you hit the wall, and the fix at that point is to archive old cards, split the board or tidy up labels.
To see a specific board's real numbers, request the board through the API with fields=limits. A developer can do it in a minute, and it's the only way to know your board's actual ceiling.
How other tools set their ceilings
Linear's docs describe initiatives that group several projects at the workspace level, for tracking goals over long timelines, which is a different way of organising work than many boards. ClickUp applies API rate limits per token by Workspace plan, 100 a minute on Free Forever up to 10,000 on Enterprise, a reminder that plan tiers set ceilings elsewhere too.

My advice if you're bumping into 10 boards
Before you upgrade, look at what your boards are for. Many people use a new board for every small project when a single board with one list per project, or labels per client, would do the same job. Close the boards you've finished, merge the tiny ones, and you'll often find 10 is plenty. If it still isn't, that's a sign your team has outgrown Free.
