You need to create a simple Gantt chart, and you need it yesterday. You don’t want to bother with installing (and learning!) complex tools. All you want is to get it done fast, and get it done right so you can showcase your project.

If this is you, you’re in the right place: in this guide, we’ll show you how to quickly make a Gantt chart online for free, while also going through a few basics and best practices you might find useful.

Let’s get started.

When do you create an online Gantt chart?

You need a Gantt chart whenever your project requires more planning than a simple to-do list. Gantt charts are visually appealing and do a great job in adding clarity to complicated data, so they can be used all throughout the project’s life cycle. Once you learn how to make a Gantt chart properly, it can help with planning, task automation, and tracking as well.

Besides the above, an online Gantt chart comes with extra perks, as it’s often collaborative, shareable, more user-friendly and simpler overall than one made with the standard project management tools that you need to install on your computer. So, when:

• you’re pressed for time
• want to collaborate with others on the same visual
• or you need to showcase your project to external audiences

… that’s when you should make a Gantt chart online.

What program do you use to make a Gantt chart?

There’s a variety of Gantt tools out there that are worth looking into. Some are paid, others are free; some are online, others are on-premise (and others offer both); some are more complex and feature-rich, others are fast and simple.
