7 Types of Org Charts and When to Use Each (With Decision Guide)
TL;DR: The seven types of org charts are hierarchical, flat, matrix, divisional, functional, network, and team-based. Hierarchical suits most traditional companies; flat works best under 20 people; matrix fits cross-functional project work; divisional and functional scale to larger organizations with distinct products or disciplines; network handles external contributor models; and team-based (pod) structures support agile, product-led teams. The decision guide at the bottom of this post narrows it down to three questions.
Most organizations end up with a hierarchical chart not because they chose it — but because it was the default. A new company copies what its founders experienced before. A growing team promotes someone and draws the lines around them. Before long, the chart exists, but no one can quite explain why it looks the way it does.
Different structures serve different realities. A manufacturing company with 2,000 employees needs clear vertical authority. A 10-person creative agency needs something closer to no structure at all. If you need a refresher on what an org chart is, start there before reading on.
This post goes beyond definitions. Each of the seven types below includes a plain "Use this if…" verdict, followed by a three-question decision guide at the end. The goal is that you finish with a recommendation, not just a taxonomy.
1. Hierarchical Org Chart
Description: The classic top-down pyramid. Each person reports to one manager, who reports to another, forming a chain of command from the executive level down to individual contributors. Authority flows vertically and is unambiguous — you always know who owns a decision. Span of control (the number of direct reports per manager) is typically narrow at senior levels and wider toward the bottom.
Best for: Manufacturing firms, government agencies, large financial institutions, healthcare systems, and any organization where consistent process execution, regulatory compliance, or safety protocols make clear chains of authority non-negotiable.
Limitations: Cross-team collaboration is not naturally built into this structure. When two departments need to work together, decisions often have to travel up one side of the pyramid and down the other. Information pools at bottlenecks, and innovation tends to migrate upward rather than emerge laterally.
Use this if: Your organization has three or more management layers and depends on clear vertical authority lines that match how your organization actually makes decisions.
2. Flat (Horizontal) Org Chart
Description: Few or no middle management layers. Most people report directly to a founder, CEO, or owner. The chart is wide rather than tall — often just two levels, sometimes three. "Flat" describes the authority axis (few layers), not the functional grouping; a flat org can still have departments, it simply has fewer managerial hops between a contributor and the top.
Best for: Early-stage startups, creative agencies, freelance collectives, and small teams under roughly 20 people. Flat structures work well when trust is high, roles are flexible, and speed matters more than process.
Limitations: Flat structures do not scale gracefully. As headcount crosses 15–20 people, informal hierarchies tend to emerge anyway — often without the accountability that formal structure provides. Without defined middle management, career progression also becomes unclear, which affects retention as teams grow.
Use this if: You have fewer than 20 people and you prioritize autonomy and direct communication over formal structure. When a flat structure starts feeling chaotic, it is usually time to introduce a layer.
3. Matrix Org Chart
Description: Employees report to two managers simultaneously — a functional manager (their department head, responsible for discipline and career direction) and a project or product manager (responsible for a specific deliverable). The two reporting lines are deliberately co-equal, or nearly so. This distinguishes a true matrix from a hierarchical-with-dotted-lines arrangement: in a real matrix, neither reporting relationship is subordinate to the other.
Best for: Consulting firms, software agencies, advertising agencies, technology companies running multiple products in parallel, and engineering organizations with embedded specialists. The matrix exists precisely because some work does not fit neatly into a single reporting line.
Limitations: Dual accountability creates role conflict when the functional manager and project manager disagree on priorities. Without clear protocols for resolving competing demands, the structure produces friction rather than flexibility. It requires higher organizational maturity to run well — ambiguity tolerance is a prerequisite.
Use this if: People regularly work across teams and carry real accountability to more than one leader at the same time, and the organization has the management discipline to maintain two accountability axes without constant escalation.
4. Divisional Org Chart
Description: The organization is divided by product line, geography, or customer segment. Each division operates semi-independently with its own functional resources — its own marketing, finance, and operations. Think of it as multiple smaller organizations nested inside a parent structure, with a corporate layer above that sets strategy and allocates capital.
Best for: Large enterprises with distinct business units — regional operations, multi-brand consumer portfolios, or conglomerates with businesses that serve different markets under different conditions. A company selling consumer software in North America and enterprise hardware in Southeast Asia may need two genuinely different organizations inside one corporate entity.
Limitations: Resource duplication is the main cost. If three divisions each maintain their own legal, HR, and finance teams, the organization carries overhead that a centralized structure would not. Coordination across divisions — for shared infrastructure, licensing, or procurement — adds friction that requires explicit management.
Use this if: Your business has multiple products or markets with their own leadership, customer base, and operating logic that genuinely differ from one another.
5. Functional Org Chart
Description: People are grouped by discipline: Marketing, Engineering, Finance, Legal, Operations. Each group is led by a functional head who owns strategy and performance for that domain. Specialists sit together and develop depth in their field.
Note on confusion with hierarchical: These two are often conflated, and the distinction matters. Hierarchical describes the direction of authority (top-down, vertical). Functional describes the grouping logic (by discipline). The two properties are independent. A functional org can be hierarchical (most are), flat, or somewhere between. Most large companies are both — organized functionally and managed hierarchically. The distinction matters when you are designing which dimension to optimize: vertical accountability or horizontal specialization.
Best for: Mid-size organizations (roughly 20–200 people) with a stable business model, where building deep expertise within each discipline creates competitive advantage. Finance, legal, healthcare administration, and engineering-heavy companies often default here because specialist career ladders map cleanly onto function-based structures.
Limitations: Functions can become silos. When teams are grouped by discipline rather than by outcome, cross-functional collaboration — shipping a product, launching a campaign, onboarding a customer — requires coordination across group boundaries. That coordination cost rises as the company grows.
Use this if: You want each function to run independently at a high level of specialization, and cross-functional coordination is manageable through defined handoffs rather than embedded collaboration.
6. Network Org Chart
Description: Maps the organization beyond the payroll. Internal employees are shown alongside external contributors — contractors, agency partners, vendors, advisors — who meaningfully shape how work gets done. The chart reflects decision influence and working relationships, not just employment status. The structure is decentralized by design: no single node is the exclusive hub of all decisions.
Best for: Distributed organizations, project-based businesses, production studios, consulting practices with large associate networks, and gig-model companies — any operation where a significant portion of execution capacity sits outside direct employment relationships.
Limitations: Network charts can become visually complex quickly. They reveal fewer formal authority relationships and more dependency relationships, which makes them less useful for compliance, escalation, or performance management — and more useful for mapping who is actually doing the work and how information flows among them. As external relationships shift, the chart requires active maintenance.
Use this if: Your team relies heavily on external contributors who genuinely shape decisions, and accurately representing that reality matters for coordination and planning.
7. Team-Based (Pod) Org Chart
Description: The primary unit is a cross-functional team — often called a squad or pod — rather than a department. Each pod contains the mix of roles it needs to execute autonomously: product, engineering, design, sometimes analytics or marketing. Each pod has a charter — an explicit definition of its scope, success metrics, and decision-making authority. This distinguishes a pod from an informal small team: the autonomy is structured, not incidental.
The contrast with flat structures is important: a flat org reduces management layers but may still be functionally grouped. A team-based org is explicitly cross-functional at the squad level. The contrast with matrix is also meaningful: in a matrix, individuals maintain a functional home and are loaned to projects; in a team-based org, the pod itself is the primary organizational unit.
Best for: Product-led technology companies, agile engineering organizations, and structures modeled on patterns observed in companies that have explicitly moved away from siloed departments toward mission-aligned teams.
Limitations: Pods require well-maintained charters. Without them, the structure looks flat but feels chaotic. Shared services (security, legal, infrastructure) that cut across all pods must be handled separately — either as internal service teams or as shared functions sitting outside the pod structure.
Use this if: You operate in squads or pods where the team — not the department — is the primary unit of accountability and delivery, and leadership is committed to maintaining team charters.
Quick comparison table
| Type | Best Company Size | Key Benefit | Main Risk | Suited For |
|---|---|---|---|---|
| Hierarchical | Any (50+) | Clear authority and accountability | Slow cross-team decisions | Corporate, government, manufacturing |
| Flat | Under 20 | Speed and autonomy | Doesn't scale | Startups, creative agencies |
| Matrix | 30–500 | Flexible resource allocation | Role conflict and dual-reporting tension | Consulting, software, product companies |
| Divisional | 200+ | Division autonomy, market focus | Resource duplication | Multi-product or multi-region enterprises |
| Functional | 20–500 | Deep specialization by domain | Siloed thinking across functions | Mid-size with distinct departments |
| Network | Any | Reflects real decision influence | Hard to maintain as relationships shift | Distributed, project-based, gig-model |
| Team-Based | 20–300 | Autonomous execution, agile-friendly | Ambiguous reporting and governance | Product-led, agile, squad-model |
Which type should you start with?
Three questions narrow the field significantly.
1. What is your headcount?
- Fewer than 20 people: start with a flat structure. The coordination overhead of formal hierarchy is not yet justified, and direct communication is still practical.
- 20 to 100 people: functional or hierarchical is the most common fit. Enough specialization exists to benefit from grouping, and enough layers to warrant clear reporting lines.
- More than 100 people: consider divisional (if you have distinct product lines or regions) or matrix (if cross-team work is pervasive).
2. Do people routinely work on multiple teams or projects simultaneously?
If yes, matrix or network structures formalize that reality rather than leaving it to informal negotiation. Both are designed for shared-resource environments. Matrix names the dual reporting; network makes the full contributor map visible, including external players. If no — most people have a single, stable primary assignment — a tree-based structure (hierarchical, functional, divisional) is simpler and sufficient.
3. Is your structure still actively evolving?
Organizations in early growth phases — still figuring out roles, responsibilities, and team shapes — often do better with team-based or flat structures that tolerate reorganization. Divisional and matrix structures carry higher reorganization costs because they encode more formal relationships. If the structure is still being designed, choose something you can revise.
One practical note: hybrids are normal. Most real organizations do not map cleanly onto a single type. A 200-person company might be functionally grouped at the department level, hierarchical within each department, and run a few cross-functional squads for strategic initiatives. The seven types here are useful lenses, not rigid boxes. The goal is to understand what each structure optimizes for — and then design something that serves the actual work.
How to build any of these in SimplOrg
SimplOrg supports both vertical and horizontal layouts, which covers the full range of chart types described above. Color coding is available for nodes — useful for distinguishing divisions, functions, or pod ownership at a glance, which makes matrix and network structures readable even when relationships are complex. For organizations with existing headcount data, CSV import works regardless of structure type, so the underlying data model is the same whether you are charting a hierarchical 500-person enterprise or a pod-based 50-person product team.

Conclusion
Structure is not neutral. A hierarchical chart built for a startup will slow it down. A flat chart stretched over a 200-person company will produce confusion instead of speed. The point of understanding these seven types is not to memorize categories — it is to recognize that different structures make different trade-offs, and the right choice depends on size, work patterns, and how stable the organization is right now.
Pick the structure that fits the actual work. Revisit it when the work changes. The chart should serve the organization, not the other way around.

Frequently asked questions
What are the main types of org charts? The seven main types of org charts are hierarchical, flat (horizontal), matrix, divisional, functional, network, and team-based (pod). Each represents a different way of organizing authority, reporting lines, and collaboration. Most real organizations use a hybrid of two or more types.
What is the difference between flat and hierarchical org charts? A hierarchical org chart has multiple layers of management between the executive level and individual contributors, with authority flowing top-down through a chain of command. A flat org chart removes most or all of those middle layers, giving individuals more direct access to leadership and more autonomy over their work. The flat vs hierarchical org chart choice is largely a function of company size and the degree of autonomy the organization wants to extend.
What is a matrix org chart used for? A matrix org chart is used when employees have two distinct reporting relationships: one to a functional manager (their discipline home) and one to a project or product manager (their current work context). It is most useful in organizations where people regularly contribute to multiple projects simultaneously, such as agencies, consulting firms, or product companies running parallel development streams.
Which type of org chart is best for a startup? A flat org chart is generally the best starting point for early-stage startups, particularly those with fewer than 20 people. It minimizes management overhead, keeps decision-making fast, and reflects the reality that most early-stage teams operate without formal hierarchy. As the company grows past 20 to 30 people, adding functional groupings or a light hierarchical layer typically becomes necessary.
Can a company use more than one type of org chart at the same time? Yes, and most mid-to-large organizations do. A divisional company might run team-based pods within each division. A functional organization might overlay a matrix structure for cross-functional projects. The org chart at the company level and the org chart within a single team often represent different structural types. The important thing is that each level of the organization is clear about how authority and work flow within that context.
