This work breakdown structure template maker turns an indented outline into a numbered WBS chart, with days added up from each work package to the top. It is free, runs entirely in your browser, and needs no account. Nothing you type or open is uploaded to a server. You can start from a built-in example template or write your own outline from scratch. The chart numbers each item for you, so labels such as 1, 1.1 and 1.2 always match the outline. Use it to map a project’s deliverables, see total effort at a glance, and export the chart as an image, SVG or PDF.

How to use the Work Breakdown Structure Maker

  1. Open the tool and either load a built-in example template or clear the editor and type your own outline.
  2. Write one work item per line. Indent child items by two spaces for each level. The tool supports up to 8 levels below the top and 200 items.
  3. Add days after a | mark, for example Plan | 5d | Ann. Put the owner after a second | mark.
  4. Add parallel after a | mark on a parent whose items run side by side. It only affects the Pro Gantt chart.
  5. If you paste text from a document, leave bullets and numbering such as 1. or 1.2 in place. The tool ignores them.
  6. Read the chart. It numbers items automatically (1, 1.1, 1.2) and adds days up from the work packages to the top.
  7. Choose a top-to-bottom or left-to-right layout.
  8. Check the list under the chart, which shows number, item, owner and days.
  9. Export the chart as PNG at 1x, 2x or 4x, as SVG, or as a picture PDF. Download the list as CSV if you need the figures in a spreadsheet.

Your work autosaves in this browser, and the Saved menu keeps named copies. To share a plan, create a share link. The document is held inside the link itself, so the person you send it to does not need an account.

How to write a work breakdown structure?

To write a work breakdown structure, start with the final deliverable at the top, split it into its major parts, and keep splitting until each lowest item is a work package that one person or team can estimate and finish. Then confirm that the children of every item add up to all of that item’s work. The steps below follow that order.

  1. Name the final deliverable as the top item.
  2. Split it into the major deliverables or phases that make it up.
  3. Split each of those again. Stop when an item is a work package, the lowest item in the WBS.
  4. Apply the 100% rule at every parent. Its children must cover all of its work, with nothing missing and nothing counted twice. The PMI Practice Standard for Work Breakdown Structures sets out this rule.
  5. Number the items and total the days. In this tool, the outline you type becomes the numbered chart with the roll-up applied.

Name items as deliverables, such as “Wireframes”, rather than actions such as “Draw wireframes”. That keeps the structure focused on what the project produces.

How are work breakdown structure templates formatted?

A WBS template is usually laid out as an indented outline, a numbered tree chart, or a list of items with owners and durations. This tool produces all three from one outline: you type the outline, the chart shows the numbers and roll-up, and the list under it gives the details.

FormatWhat it showsWhere it appears in this tool
Indented outlineItems nested two spaces deeper per levelThe input you type
Numbered chartNumbers such as 1, 1.1, 1.2 and days rolled up to the topThe chart, top to bottom or left to right
Item listNumber, item, owner and daysThe list under the chart, downloadable as CSV

Here is a small website example. The outline is Website with Plan 5, Design (Wireframes 8, Visuals 7) and Build 20.

ItemNumberDays
Website (top)040
Plan15
Design215
Wireframes2.18
Visuals2.27
Build320

Design shows 15 days because it rolls up its two children. The project totals 40 days across 4 work packages. Days go on work packages, and days typed on a parent are not used. Weeks and hours also work: 2w counts as 10 days and 16h as 2. A plain number such as 2024 Budget stays in the name, and a note tells you when an outline goes past the limits.

Frequently asked questions

Why use a work breakdown structure template?

A template gives you a working outline to start from, so you are not building the layout from nothing. Changing the days or items updates the roll-up, which keeps the project total current as the plan changes.

Who uses a WBS template?

Project managers, team leads and planners use it most often, usually at the planning stage. Anyone who needs to see a project split into parts, with an owner and days for each part, can use it.

What’s inside the WBS template?

The built-in examples give you a complete outline to edit, such as Website project, Product launch or Mobile app development. The chart, the list under it and the exports all update as you change the outline. Each line can carry days and an owner.

What are the 5 steps of WBS?

There is no single fixed count of steps. Follow the order in the guide above: name the final deliverable, split it, stop at work packages, check the 100% rule, then number the items and total the days.

Can I use a WBS in Excel?

Yes. Build the outline here, then download the list under the chart as CSV, which opens in Excel and other spreadsheet programs.

Is the WBS template free to use?

Yes. The outline, numbering, roll-up, PNG, SVG and picture PDF exports are free, with no watermark and no account. You may use the results commercially without attribution. Pro adds a Gantt chart with one task per work package, a vector PDF and an editable .drawio file.
