What Is A Gantt Chart?

A Gantt chart contains information about completed and remaining work in a project in the form of a bar chart. 

It’s a pretty comprehensive chart where you plot every single event, outcome, delivery, and stakeholder in a project.

Project managers use Gantt charts to:

  • Map overall project timeline
  • Estimate the project completion date
  • Assign project tasks to relevant people
  • Track project progress
  • Share project progress with stakeholders
  • And more

While Gantt charts started off as sophisticated tools for highly trained project managers, any project team member can look at a modern Gantt chart and understand where the project is headed.

How To Make A Gantt Chart In Google Sheets

Here’s a step-by-step guide on how to create a basic Gantt chart in Google Sheets. 

1. Insert basic data

Create a new Google Sheet  document. 

Then, add basic project data over the:

  • Task name
  • Tasks’ start date
  • End date

The table should look like this: 

gantt charts in google sheets

Now, this is only a reference table. 

Creating the Gantt chart involves calculating task durations, which we’ll do in the next step. 

2. Calculate task durations

Copy-paste the same table a few rows below the original table. 

Now, rename the ‘End date’ column as ‘Task duration’ and delete the data in that column. The rest remains the same. 

Calculate task durations in google sheets

In the first cell of the ‘Start date’ column, copy-paste this formula: =INT(B2)-INT($B$2)

Note: Here, B2 stands for the cell number of the first date in the original ‘Start date’ column. Feel free to change these values if your table positioning is different. 

Once you copy-paste this formula, the sheet converts the date to an integer for the number of days in the date range. In our example, it becomes day 0

Pro Tip: If you get 12/30 rather than 0, ensure that you are in Automatic format, not Date format. Change this by selecting ‘Format’ > ‘Number’ > ‘Automatic’ for all cells in the task duration table.

Now copy-paste the same formula into each cell, all the way down to the last task in the same column. This will give an absolute integer value to the start date of each task in the project cycle. 

Next, we’ll calculate the task duration. 

To do that, copy-paste this formula in the first cell of the ‘Task duration’ column: =(INT(C2)-INT($B$2))-(INT(B2)-INT($B$2))

Similar to what you did in the earlier step, copy-paste it down to the last task in the same column. The resulting table will show you how long each task takes in a number of days

Note: This does not account for any non working day

3. Generate a stacked bar chart

Select all the cells in the second table, go to Insert in the top drop down menu, and select Chart

Google Sheets automatically generates a stacked bar graph. But you can change the chart type whenever you want. 

Reposition it and edit the chart name.

4. Format the chart

Select the ‘Start date’ portion of the chart. It’s usually the light-themed bars on the chart. 

In our example chart, the blue portions represent the start date. 

Once you select a bar, go to the color menu in the chart editor window and select ‘None.’

Pro Tip: An updated version of Google Sheets no longer has ‘None‘ as an option, so if this is the case for you, select ‘White’ with ‘Opacity’ set at 0% to essentially remove any fill.

This completes the classic Gantt chart look!

You can now edit the original data table and see the changes reflect in your Gantt chart. 

The best part about a Gantt chart? 

You just need a single glance to identify any overlapping tasks.

5. Customize the Google Sheet Gantt chart

In the chart editor pane, there are additional customizations that you can feel free to explore. We’ve highlighted the top 3 most practical ones:

Update the chart area

You can customize the following:

  1. Background color
  2. Border color
  3. Font – this will change the font for the entire chart
  4. Change the bars to 3D
customize tab

Update axis titles

You can add a chart subtitle and edit the names of the Horizontal and Vertical axis.

Hide the legend

You are also able to move and format the legend. Since a Gantt chart doesn’t typically require a legend, you can also hide it.

6. Adding dependencies to your Gantt chart

Complex projects will require dependencies, meaning tasks are dependent on one another’s initiation or completion.

First, read about the 4 types of logical dependencies in our blog to brush up on your understanding of these logical types. We can use Google sheet formulas to ensure that key tasks are linked to dependent tasks when remapping due dates or start dates.

Finish to start

To create a finish-to-start dependency, determine which task must complete before another can start. In our example, under the Task Name column, we’ve determined that Prototyping phase 1 must complete before Design phase 2 can start.

  • Prototyping phase 1’sEnd Date‘ is scheduled in C5
  • Design phase 2’sStart Date‘ is scheduled in B7

In B7 (the ‘Start Date’ of Design phase 2), type this formula: =max(C5)+1

task's start date is linked to first task

Now Design phase 2 will depend on Prototyping phase 1’s completion!

Start to finish

When a task requires another one’s initiation in order to end, we need a start-to-finish dependency. For example, we might need Design phase 1 to start before finishing Submitting the project charter as it may be good to include design mockups in the project charter.

  • Design phase 1’sStart Date‘ is scheduled in B4
  • Submitting the project charter’sEnd Date‘ is scheduled in C2

Let’s say that it takes 4 days for the design team to have some design drafts ready, so in C2, input this formula: =min(B4)+4

Finish to finish

Sometimes a task has to finish in order for another to finish. For example, in our example, Testing phase 1 must finish before Prototyping phase 1 can finish the next day afterwards. This is because prototyping is a key task that encompasses testing.

  • Testing phase 1’sEnd Date‘ is scheduled in C6
  • Prototyping phase 1’sEnd Date‘ is scheduled in C5

In C5 (the ‘End Date’ of Prototyping phase 1), type this formula: =min(C6)+1

Note: Since Prototyping phase 1 needs one extra day to complete after Testing phase 1 finishes, we need +1 in the formula.

mapping end dates

Start to start

Lastly, a task that requires the initiation of another before it can start should use the start-to-start dependency. For example, we can’t start Submitting the project plan unless Submitting the project charter has started, since the charter is the underlying document for the whole project. However, we will probably need a bit of time (7 days) before we can start scoping the project plan.

  • Submitting the project charter’sStart Date‘ is scheduled in B2
  • Submitting the project plan’sStart Date‘ is scheduled in B3

In B3 (the ‘Start Date’ of Submitting the project plan), type this formula: =max(B2)+7

With these dependencies created, you now have a dynamic Gantt chart in Google Sheets to easily remap dates based on real-time data.

3 Drawbacks Of a Google Sheet Gantt Chart

Google Sheets is free, flexible, and very difficult to hate!

It’s certainly better than using Excel to make Gantt Charts, any day. 

See, we’re part of the Google Sheets fan club too! 

However, it isn’t a Gantt chart tool.

Read on to see why Google Sheets is not the right tool for creating Gantt charts and why you’ll need Gantt chart software

1. No project task management

You may have a comprehensive Gantt graph in Google Sheets, complete with deadlines and deliverables. However, does it even matter if you can’t use it to navigate your project on the ground?

To do that, you’ll need basic task management functionalities like:

  • Assigning tasks to individuals
  • Scheduling on calendars
  • Managing dependent tasks
  • Estimating the completion date with real-time data, etc.

Google Sheets is no help in this department. Well, you could technically make a calendar in Google Sheets.

But effectively, it gives you a dead Gantt chart. 

Great for slideshows. Not much else, though. 

2. Limited integrations

Good project management software can integrate with other tools to ensure you have everything you need.

Unfortunately, Google Sheets doesn’t. 

It tries its best to compensate with Chrome extensions and add-ons. 

But that’s hardly enough, is it?

3. Limited mobile functionality

Scrolling through a Google spreadsheet on your phone will feel like playing a ‘90s video game, just less fun. 

So unless your idea of project management involves being chained to a desk, we don’t recommend Google Sheets. 

Instead, why not pick the world’s highest-rated productivity tool as your go-to Gantt chart maker?
