How to make a hierarchy chart
- Line 1 is the top of the hierarchy. A CEO, a department head, a board — whatever the highest authority in the scope you are drawing is. If there are genuinely two people at the top, put them on one line:
CEO & COO. - Indent one level per level of authority. Everyone at the same indentation under the same parent reports to that parent. Two spaces or one Tab makes a level.
- Name roles, not just people. "VP Engineering — Dana Ruiz" survives a reorg better than a bare name, and it is what makes the chart useful to someone who has just joined.
- Use Tab and Shift+Tab to restructure. They move the selected line and everything nested beneath it, so promoting a team under a different VP is two keystrokes rather than a redraw.
- Switch to left-to-right for deep charts. Top-down suits wide, shallow organisations; sideways suits tall ones and fits a portrait page.
- Export. PNG and PDF for slides and handbooks, or copy the plain-text tree for a wiki or a README.
Hierarchy chart, org chart, or hierarchy diagram?
These are three names for the same picture, used by different audiences. Organizational chart is the HR term and usually implies people and reporting lines. Hierarchy diagram is the generic one and shows up in documentation, taxonomies, and systems design. Hierarchy chart sits between them and is the term most people search for when they want the shape without the corporate framing — a church hierarchy, a police rank structure, a classification of food groups. This tool draws all of them, because the underlying structure is identical: a root, nested children, one indent per level.
Structures a hierarchy chart handles well
- Functional organisations. Departments under executives, teams under departments. The default shape, and the one indentation models exactly.
- Rank structures. Military, police, clergy, civil service — where the levels are formally defined and every position has exactly one level above it.
- Taxonomies and classifications. Categories inside categories, with the leaves being the actual items being classified.
- Product and system breakdowns. A system into subsystems into components, which is the same chart engineers call a work breakdown structure.
The one structure it does not model is a matrix organisation, where a person reports to two managers. A tree gives every node exactly one parent, so a dotted second reporting line has nowhere to live. The usual workaround is to draw the solid line in the chart and note the dotted one in the role label — which is honest about the fact that a matrix is not really a hierarchy.
Keeping a hierarchy chart readable
The failure mode of hierarchy charts is showing everyone. A chart with two hundred names is a seating list, not a diagram, and nobody reads it twice. Draw one chart per division and link them, stop at the level where the reader's question is answered, and let the depth of the chart make its own argument: if you need seven levels to get from the top to the person doing the work, the chart has told you something more useful than the names on it.
Because the whole chart is plain text, it also diffs. Keep the outline in version control alongside your handbook and a reorg becomes a reviewable change rather than a new file called org-chart-v4-FINAL.pptx.
Frequently asked questions
What is a hierarchy chart?
A hierarchy chart is a diagram showing which positions sit above which, with one item at the top and lines running down to everything that reports into it. In a company it is usually called an org chart; the same shape is used for government structures, church hierarchies, military ranks, taxonomies, and file systems.
Is a hierarchy chart the same as an organizational chart?
An organizational chart is a hierarchy chart applied to an organisation. The word hierarchy is the broader one — any strict top-down ranking is a hierarchy chart, whether or not people are involved. Every org chart is a hierarchy chart; a taxonomy of animals is a hierarchy chart but not an org chart.
How many levels should a hierarchy chart have?
As many as the structure genuinely has, but readability drops fast past five or six. If your chart is running deeper than that, either the diagram is trying to show the whole organisation at once — split it into one chart per division — or the structure itself has more layers than it needs.
Can I export the hierarchy chart?
Yes. PNG and PDF exports are free and carry a small footer watermark. You can also copy the hierarchy as a plain-text tree using box-drawing characters, which never carries a watermark and pastes into documentation, a README, or a wiki page.
For hierarchies that branch on a choice rather than on authority, the decision tree maker and its decision tree templates add edge labels and outcome styling. Family hierarchies belong in the family tree diagram maker or the cousin chart, biological ones in the cladogram maker. The tree diagram maker is the general engine, text to tree turns the same outline into copyable ASCII, and the examples gallery opens every preset in the editor.
