What is a Gantt Chart?
A Gantt chart is a horizontal bar chart that maps tasks across a timeline, showing when each task starts, how long it runs, and how tasks relate to one another. It is the go-to format for project planning because it makes schedules, phases, and dependencies visible at a glance. Use one whenever you need to coordinate multiple people or workstreams toward a shared deadline.
Key Features
Task Dependencies
Link tasks together so reviewers can instantly see which work must finish before the next can begin.
Sections and Phases
Group related tasks under named sections — such as Design, Development, or QA — to mirror your project structure.
Status Indicators
Mark tasks as Active, Done, Critical, or Milestone to communicate real-time progress without a separate status report.
Zoom and Pan
Navigate long timelines with smooth zoom and pan controls so no tasks are hidden off-screen.
Custom Date Formats
Choose from multiple date and axis formats to match your region or reporting standard.
Best For
Software development sprints
Product launch planning
Construction and renovation projects
Marketing campaign schedules
Event planning timelines
Research and thesis project milestones
When to Use
- You have multiple tasks that must be completed in a specific sequence
- You need to show start and end dates alongside task duration
- Your project has distinct phases or workstreams that overlap
- Stakeholders need to see the full schedule at a glance
- You want to highlight critical-path tasks that could delay the project
- You are coordinating work across two or more people or teams
Common Mistakes
- Cramming too many tasks into one chart — break large projects into phases and use separate charts per phase
- Skipping dependencies — tasks shown without links make it impossible to assess knock-on delays
- Using vague task names like 'Work on feature' instead of specific, measurable deliverables
- Forgetting to mark milestones — key approval or release dates should stand out, not blend in as regular tasks
- Setting every task duration to one day, which flattens the timeline and hides real complexity
- Not updating status as work progresses, turning the chart into a static document rather than a live planning tool
