Free Gantt Chart Template — Excel & Google Sheets
Plan project phases, owners, and milestones on a 12-week timeline. Colour-coded bars make schedules easy to scan in Excel, Google Sheets, or Griddy.
What is a Gantt chart?
A Gantt chart is a project schedule shown as horizontal bars across time. Each row is a task, and each filled block shows when that task is planned to happen. That makes dependencies, overlaps, and launch timing much easier to understand than a plain task list. This free Griddy template turns that structure into a practical weekly roadmap you can use in Excel, Google Sheets, or directly in your browser.
What's included
The template includes phase bands for discovery, design, build, and launch; a left-hand task table with owner, start date, end date, duration, status, and percent complete; and a 12-week timeline on the right with colour-coded schedule bars. There is also a milestone row and a legend so the roadmap stays easy to scan in presentations and internal planning reviews.
Who should use this template?
Project managers who need a lightweight alternative to MS Project or Asana. Team leads presenting project plans to stakeholders. Freelancers planning multi-phase client projects. Small businesses coordinating product launches, office moves, or events.
How to use it
Replace the sample tasks with your own project phases and deliverables, then adjust owners, dates, and durations in the left table. Move or extend the coloured timeline bars to match your real schedule, and use the milestone row for launch dates or major approvals. If plans shift, ask Griddy's AI to add a new phase, push a workstream back two weeks, or rewrite the roadmap around a new deadline.
