Trello Free Plan Limits: What Actually Caps You (2026)
The hard cap on Trello’s free plan is 10 boards per Workspace — not cards, not Power-Ups, both of which are now unlimited. The other limits that actually constrain you are 10 collaborators per Workspace, 250 automation runs per month, and a 10 MB per-file attachment ceiling.
What the Free Plan Includes (and Caps)
Included / unlimited
- Unlimited cards, per Trello’s pricing page.
- Unlimited Power-Ups per board — the old one-Power-Up-per-board rule was dropped in 2021 and free users now get unlimited integrations.
- Unlimited storage, with a per-file ceiling (below), plus mobile apps, two-factor authentication, and basic Kanban boards, lists, and cards, listed on the pricing page.
Capped
- 10 boards per Workspace, confirmed on the pricing page.
- 10 collaborators per Workspace, per Atlassian’s free Workspace limit doc.
- 250 Workspace command (automation) runs per month, per Trello’s automation quotas doc.
- 10 MB max per file attachment, confirmed on the pricing page.
- No Calendar, Timeline, Table, Dashboard, or Map views — those are paid only, per the pricing page.
The 10-Board-Per-Workspace Cap Is the Real Wall
Most “Trello is unlimited on free” advice is half-right. You do get unlimited cards and unlimited Power-Ups, so a single board never fills up the way it once did. But every free Workspace stops you at 10 boards, and that limit arrives fast once you split work across projects, clients, or teams.
There’s no per-card or per-list cap to worry about — the constraint is purely the number of boards. Standard ($5/user/month) is the tier that removes it, jumping you straight to unlimited boards, which is why the upgrade decision for most people comes down to “do I have more than 10 active boards?”
How to Work Around the Free Plan Limits
- Archive boards you’ve finished. Archived boards don’t count toward the 10-board cap, so close out completed projects instead of leaving them open.
- Consolidate boards into lists. Cards are unlimited — collapse several small projects into lists on one board rather than spinning up a board per project.
- Host large files elsewhere. The 10 MB per-file limit is per attachment — store big decks or videos in Google Drive or Dropbox and attach the link, which counts as one card link, not an upload.
- Batch and prune automations. With only 250 runs per month, avoid rules that fire on every card move across a busy team; reserve Butler for high-value triggers and check the usage log.
- Use guests sparingly. Free Workspaces cap at 10 collaborators; add only the people who need to edit, and share read-only board links with everyone else.
Troubleshooting
How many boards can you have on Trello free?
10 boards per Workspace. Cards within those boards are unlimited, but the Workspace itself stops at 10 boards on the free plan. Standard and above offer unlimited boards.
Does Trello free have a card limit?
No. Cards are unlimited on every plan, including free. There is no per-board or per-list card cap — the only board-related limit on free is the 10-board Workspace ceiling.
What is the attachment size limit on Trello free?
10 MB per file. Anything larger requires a paid plan, where the per-file limit rises to 250 MB on Standard. Storage overall is unlimited; the cap is per individual file.
How many automation runs do you get on Trello free?
250 Workspace command runs per month. Standard raises this to 1,000 and Premium is unlimited, so heavy Butler users are the ones most likely to hit a paid wall.

See what people say
"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."
