Gantt Chart Examples, Templates, and Styles

A Gantt chart is a simple bar chart that shows all the tasks, events, and milestones in a project. The x-axis depicts the project timeline, and the y-axis depicts project phases. Each horizontal bar represents a project task. 

In most Gantt charts, the current date is represented by a vertical line, which looks like a progress bar. 

Other common symbols are diamonds or stars, which represent milestones. 

Many Gantt charts use color-coding to separate project phases.

“When creating a Gantt chart, each task is represented by a bar that extends over the duration of the task,” says Danny Trichter, Co-Founder of AccessibilityChecker.org. “The length of the bar indicates the duration of the task, and the placement of the bar indicates when the task will begin and end. In addition, Gantt charts often include information such as task dependencies, milestones, and resources.” 

For some projects, especially those with tight deadlines, it can be helpful to include project dependencies in your chart. These are typically represented with arrows. You can use arrows to distinguish between the four types of dependencies: finish-to-start, start-to-start, finish-to-finish, and start-to-finish.

You can also use Gantt charts to represent lead time, lag time, predecessor tasks, and successor tasks when necessary. 

“Gantt charts should be created in a way that is easy to read and understand. I believe if it's not simple, people won't use it,” says Chad Sibila, Sales Manager at VT Industries. “I really like to see a left-to-right, start-to-finish for one project, with the steps to complete along the way.”
