How to Make a Timeline in Google Slides

Google Slides has timeline layouts under Insert, then Diagram. They are quick and evenly spaced — which is fine for a narrative timeline and wrong for a project schedule, because equal spacing implies equal duration.

Last reviewed: August 2026

Two ways to build one

  1. Use Insert, then Diagram, then Timeline

    Pick the number of steps and a colour, and Slides inserts an editable grouped diagram. Fastest route for a simple narrative.

  2. Edit the inserted labels

    Click into each node. The shapes are ordinary Slides objects, so you can restyle them individually.

  3. Or draw it by hand for accuracy

    A line plus positioned markers lets you space events by real elapsed time rather than evenly.

  4. Space by duration if it is a schedule

    Put a January and a December milestone eleven months apart on the axis, not next to each other.

  5. Label the axis

    An undated timeline is a sequence, not a schedule. Say which it is.

  6. Mark today

    A vertical marker for the current date is what makes a project timeline readable at a glance.

Menu labels move. The sequence above is stable, but Google and Microsoft relabel and reposition menu items regularly. If an item is not where this says, search the app's own help rather than trusting any third-party guide's screenshots — including ours.

The mistake that makes timelines misleading

  • Even spacing implies even duration. The built-in diagram spaces steps equally regardless of dates, which flatters a plan with a long gap in it.
  • No axis means no accountability. A timeline without dates cannot be checked against reality later.
  • Milestones without owners. A date with nobody's name against it slips silently.
  • Too many events. Beyond about seven the timeline stops being readable; group the minor ones.
  • Use a Gantt when there are dependencies. A timeline shows sequence; a Gantt shows overlap, float and what blocks what.

Frequently asked questions

How do I make a timeline in Google Slides?

Use Insert, then Diagram, then choose a timeline layout and the number of steps. The result is an editable group of ordinary shapes you can restyle and relabel.

Can I space a Google Slides timeline by real dates?

Not with the built-in diagram, which spaces steps evenly. For a schedule, draw a line and position markers by elapsed time, or use a Gantt tool that computes positions from dates.

What is the difference between a timeline and a Gantt chart?

A timeline shows sequence — what happened or will happen, in order. A Gantt shows duration, overlap and dependencies, which is what you need once tasks block each other.

How many events should a timeline have?

Around seven or fewer. Past that it stops being readable at a glance, and the minor events are better grouped into phases.

Should a project timeline show today's date?

Yes. A marker for the current date is what lets an audience see at a glance whether the plan is ahead or behind, and it is the most commonly omitted element.

Build the deck, not just the slide

Gixo Lumen turns your material into a sequenced deck across 26 slide layouts and 34 themes. Building manually from a blank deck is unlimited and uses no generation capacity with an active Lumen trial or plan, and PPTX export carries no paywall.
