Gantt charts are a must-have in every planner’s toolbox because they give you a clear visual of project tasks, dependencies, and deliverables over time.
If you’ve never made a gantt chart before, you might not know where to start. This tutorial will guide you through every step of the process and equip you with the tools you need to feel confident your gantt chart is done right.

There are lots of different ways to make a gantt chart—from traditional desktop apps to collaborative project management software. No matter which tool you use, the basic steps are the same.
In this tutorial, we’ll use TeamGantt to show you how it’s done. Sign up for a free account to follow along and create a gantt chart of your own.
You can’t build a gantt chart without a clear idea of the work that needs to get done. That’s why it’s important to gather the right details first.
These questions can help you scope out your project before you sit down to create a gantt chart:
See what goes into a good project scope document.
Lots of project managers use a work breakdown structure (WBS) to identify all the tasks you’ll need to complete to consider your project done. You can sketch your WBS out in a spreadsheet, flowchart, or outline.
Explore different formats for building a work breakdown structure.
No matter what format you choose, the basic process for creating a WBS is the same:
The more detail you can spell out when it comes to tasks, the better you’ll be able to track progress and steps leading up to a deliverable.
Tip: Save time on project setup by adding tasks and subtasks directly into TeamGantt instead of creating a separate WBS file. Or import your work breakdown structure into TeamGantt as a CSV file.
Your task list makes up the y-axis of your gantt chart. So take all the tasks and subtasks you outlined in a work breakdown structure, and add them down the left side of your chart.
Go ahead and organize your tasks into phases or subgroups at this stage. Adding structure to your task list will make your gantt chart easier to scan and understand. It’ll also allow your team and stakeholders to see what tasks are part of a deliverable or a phase.
Here’s how to add tasks to your gantt chart in TeamGantt:
Tip: Want to avoid overwhelming stakeholders with details they don’t need? Collapse task groups down during meetings to present a high-level view of your gantt chart.
Now that you’ve got a full list of work to be done, you’re ready to map out a visual timeline. Add start and end dates to each task on your list, and draw a horizontal bar on the right side of the diagram to represent the duration of work.
TeamGantt makes scheduling tasks super-simple because you can drag and drop each task on your timeline. Here’s how:
Adding milestones to your gantt chart makes it easy to track project deadlines, approvals, meetings, and other key deliverables or events. Milestones typically appear as a yellow or gold diamond on your gantt chart to set them apart from day-to-day tasks.
Here’s how to add a milestone to your gantt chart in TeamGantt:
See examples of how to use project milestones.
If you’re not going to move forward on the project without an approval—or one task must be done before another—this is your chance to note it. So take a moment to review your gantt chart and identify any dependencies.
Not every planning tool offers dependency functionality, and it can be a huge help. As your plan shifts, the flow of the work will stay intact.
Here’s how to link dependent tasks in TeamGantt:
Now you’re ready for resourcing! Invite your team to the project, then assign each task in your project to the person responsible for the work. Be sure to account for any non-human resources in your plan, such as equipment or facilities needed.
Here’s how resource assignment works in TeamGantt:
Once you’ve assigned tasks in TeamGantt, you can use filters to view only the work assigned to a particular person or label.
Tip: In TeamGantt, you can set up labels for resources that don’t require project access or email notification. This enables you to check availability right from your gantt chart and avoid overbooking an important resource.
Color is a great way to customize your gantt chart and make it easy to understand at a glance. Use different colors to categorize tasks by project phase, department, team member, or priority. It’s up to you!
Here’s how to apply colors to gantt chart tasks in TeamGantt:
Tip: In TeamGantt, you can set a default task color for each person or project label to automatically apply that color to any task you assign to them.
Lay a clear path to success with a visual plan that’s easy to understand, and keep everyone in sync with flexible workflows and team collaboration.
If you want to build a gantt chart everyone can use and navigate, there are a few simple rules you should keep in mind. Follow these simple tips and best practices to make a good gantt chart that’s easy to update and manage.
Sometimes your team and clients may forget what they committed to. Or maybe they don’t fully understand the intent of a task or group.
Use the notes section of your plan (most gantt chart software should provide this) to spell things out. While you’re at it, be sure to upload key files directly to the task so everything’s ready and waiting for work to begin.
In the project sample below, we added notes about the scope of the task and uploaded a copy of the creative brief for more detail.
This tip comes in handy for any project, but it’s especially useful for client projects. Identifying which team or company is responsible for each task makes your gantt chart super-easy to scan.
When creating a task, you can assign labels you've set up on the People tab or simply put the company name (or an acronym) in front of the task. Here’s how we tagged tasks in the example below:
Of course, you’ll also want to take that a step further and assign each task to the person responsible. This will help you with resource allocation and accountability.
Seems like a silly tip, but it’s easy to hide this info in some apps! If you’re using TeamGantt, you’ll see the dates in the gantt view.
Regardless of what tool you’re using, you want to make it clear not only when a task ends, but when it starts. Again, this will help to keep your team and clients accountable.
If your team uses multiple apps to collaborate on projects, why not integrate them with your gantt chart so everything connects back to the plan? Here are a few popular integrations you can use in TeamGantt to streamline effort and maximize productivity:
Don’t let simple mistakes undermine your plan. Watch out for these common pitfalls when building your project gantt chart:
If you’re lucky enough to use a product that shows you overall team availability, use it! Knowing how booked your team is and what projects they’re part of will play a huge role in delivering work on time and maintaining team morale.
Having an overall view of your team’s availability and conflicting work will help you adjust your plan to either meet the needs of existing project work or shift the milestones you’ve put in your plan.
Here's how to view team availability directly from your gantt chart in TeamGantt.
Now is your chance to block time off in your plan. This is important now because as soon as your timeline shifts (you know it will, don’t fight it), you’ll open yourself up to making an error and dropping a deadline on a date that should be blocked. If you note them in your plan, that won’t happen.
If you deliver a plan that has a mistake, misinterprets a task, or even misses a date, it can create confusion and delays. So grab a teammate and ask them to review your gantt chart before you post it for review.
Of course, you’ll also want to be ready to get some feedback on your plan. Formalizing a plan means you’re taking a set of ideas and expanding on them. That also means you might interpret something differently than a teammate. That’s okay!
A gantt chart is a living, breathing document that should keep up with project changes—not a fixed plan that’s set in stone. Invite your team to collaborate on work and track progress in real time so your gantt chart’s always up-to-date.
If you’d rather use a spreadsheet to build your gantt chart, we’ve got guides for that too. Just be sure to choose a gantt chart builder that gives you the features you need.
