How to create a Gantt chart: step-by-step process
Let’s take a look at the key steps involved in creating a Gantt chart from scratch.
Step 1: Gather project information
Before you build a Gantt chart, you need a clear picture of the work ahead. This includes knowing what the project aims to achieve, listing all required tasks, estimating how long each one will take, and identifying important milestones.
- Define scope: Clearly establish the project’s goals and what needs to be achieved.
- List tasks: Create a comprehensive list of all tasks required for the project.
- Estimate durations: Determine how long each task will take.
- Identify milestones: Pinpoint key project milestones, which are significant points or deadlines.
- Assign resources: Determine who is responsible for each task.
- Note dependencies: Identify any tasks that must be completed before others can start.
Step 2: Choose a tool and create the chart
There are two most popular ways to make a Gantt chart: create a spreadsheet (like Excel) or to use project management software.
- If you use a spreadsheet: Create a simple table with task details, then turn it into a stacked bar chart and format it to resemble a Gantt chart.
- If you use project management software: Input your project data into a dedicated tool, which can automatically generate the chart and handle dependencies.
Step 3: Refine and share the chart
Once the basic chart is ready, add milestones, dependencies, and resource assignments, and adjust the colors or layout so the timeline is easy to read.
- Add details: Add milestones, dependencies, and resource assignments to your chart.
- Customize appearance: Use color-coding to distinguish different phases or task types and add a project title.
- Review and collaborate: Share the chart with your team to gather feedback, identify potential issues, and ensure alignment.
- Present: Share the final version with stakeholders via email, a link, or a presentation.
How to make a Gantt chart in Excel
Excel is a good option when you need a simple Gantt chart without using dedicated project management software. The process takes a few minutes and gives you a visual timeline you can share with your team.
Create a table with task details
Start by entering your tasks into a table with columns for task name, start date, and duration. You can also add an end date column if you want Excel to calculate it automatically. Keeping this table clean and structured will make the chart easier to build.
Use a formula to calculate end dates
If you include an “End Date” column, use a simple formula such as Start Date + Duration to calculate when each task finishes. This helps ensure your timeline is accurate and saves you from updating dates manually later.
Select your data
Highlight the start date and duration columns along with the corresponding task names. This selection tells Excel which information to use when generating the chart.
Insert a stacked bar chart
Go to the chart options and choose a stacked bar chart. Excel will create a basic layout where the first segment represents the start date and the second segment shows the task duration.
Format the chart to look like a Gantt chart
Make the start date segments invisible by setting their fill color to “no fill.” This shifts the visible duration bars into position along the timeline. Remove the legend, adjust colors and labels as needed, and your Excel-based Gantt chart is ready.

FAQs
What is a Gantt chart and how to create it?
A gantt chart is a visual timeline that shows how work is organized across a project schedule using horizontal time blocks. It typically includes start and end dates so you can see when each activity begins and finishes. Teams often begin with a gantt chart template to outline steps quickly, but GoodDay makes it even easier by automatically building the structure for you. To create a gantt chart, you simply add your tasks and dates, and GoodDay generates a clear layout instantly.
How do Gantt charts work?
They visualize tasks as horizontal bars arranged on a grid where time flows from left to right along the vertical axis. Each bar reflects timing, connections, and dependent tasks, giving teams a clear picture of the workflow. Relationships such as task dependencies help identify the critical path, which determines the minimum completion time. GoodDay automates these calculations so teams stay accurate when schedules shift.
How to use a Gantt chart?
A chart like this organizes all the tasks into a timeline so teams can review responsibilities and sequencing. You can assign tasks to team members and see how they relate to the project scope. As the work evolves, the gantt chart helps you spot task progress and how changes may affect the overall plan. GoodDay simplifies this by offering real-time updates and clear visibility for every team involved.
How to make a Gantt chart?
You begin by writing out major activities and arranging them into a simple gantt chart so the plan becomes easy to understand.

GoodDay supports this end-to-end setup and gives teams the most reliable charting experience.
How to create a Gantt chart in Word?
In Word, you can use tables or online templates to build a basic timeline with columns for dates and tasks. To improve clarity, adjust bar color manually so tasks are easy to distinguish. Word does not calculate logic or relationships, so it’s limited for planning. This is why GoodDay is a better choice because it provides automation instead of static formatting.
How to create a Gantt chart in PowerPoint?
PowerPoint requires inserting rectangles or a bar chart and shaping them to represent task bars. While visually flexible, it lacks features for tracking percent complete or linking data. Teams must press delete and redo elements whenever dates shift, which is time-consuming. GoodDay eliminates manual work by generating dynamic charts that update with every change.
How to create a Gantt chart in Google Sheets?
You start by listing tasks and dates, then using conditional rules such as conditional formatting to highlight sequences.
