Per-file and total storage limits are different
One large file can fail an otherwise small project
A project containing a 12 MB file has at least 12 MB of attachments. Trello Free’s checked 10 MB per-file limit is different from its overall storage allowance. Splitting a project across boards does not change the size of that file.
Many small files can reach a total limit
Twenty files of 4 MB total 80 MB. Each file is modest, but the total exceeds the checked 60 MB ClickUp Free Forever storage allowance. The calculator uses the total you enter; it does not scan or upload your files.
Check the missing dimensions
ClickUp’s per-file ceiling is not confirmed by this tool, so its result retains that limitation. Permissions, file retention and other feature quotas also need checking. A numerical fit should not be presented as a complete product recommendation.
A practical first test
Use non-confidential sample material in the chosen service and confirm who can open, change and export it. If another approved storage tool already holds large files, decide whether linking to it meets your team’s access requirements. This site does not provide team setup or migration services.
