How to Create an Information Architecture Diagram in Figma

Information architecture defines how your product organizes, labels, and navigates information. Before designing screens, a clear IA diagram answers the fundamental structural questions: what are the top-level categories, how do they relate, and where does each piece of content live?

This guide covers creating IA diagrams in Figma that serve as the structural backbone for your product design, linked directly to the screens they define.

Step-by-step guide

01

Create an IA page in your Figma design file

Add a new page called Information Architecture to your product design file. Creating the IA in the same file as your screens allows Figma prototype linking to connect IA nodes to actual screen designs. Set up an 8pt grid and create a large frame (3000x2000) to give the diagram room.

02

Start with the top-level navigation nodes

Place the product name at the top-center. Below it, create one rectangle for each top-level navigation item: Dashboard, Projects, Settings, Help, Profile. Use a consistent rectangle size (200x48px at 1x scale). Apply a distinct fill color per hierarchy level: dark for level 1, medium for level 2, light for level 3.

03

Expand each node into its sub-categories

For each level-1 node, draw its children below it: Dashboard breaks into Overview, My Projects, Team Activity. Use vertical lines and horizontal brackets to show parent-child relationships. Apply Auto Layout (Shift+A on Mac) on each parent container to keep children evenly spaced as you add or remove nodes.

04

Add content types and page templates as labels

For leaf nodes (pages with no children), add a small label below the node indicating the content type: List, Detail, Form, Modal, Dashboard. This tells designers which screen template applies. Use consistent Figma text styles to distinguish content type labels from node labels.

05

Mark shared components and cross-links

Some elements appear in multiple places: global search, notification center, user profile. Mark these with a dashed border and a note Global Component. Use Figma connector arrows with dashed stroke to show cross-links between sections, such as a Project Detail page linking to Ticket Detail in another section.

06

Annotate navigation patterns

Add Figma text annotations explaining the navigation mechanism per level: Top-level is persistent sidebar, Level 2 is tab navigation within page, Level 3 is inline expansion. These annotations translate directly into frontend navigation component requirements for engineering.

07

Link IA nodes to screen designs using components

Convert each IA node to a Figma Component (Cmd+Alt+K). In the component master, add a Link property pointing to the corresponding screen frame. When you share the IA, each node is clickable and jumps to the screen design. This creates a live, navigable site map from the IA diagram.

Common mistakes

Confusing IA with a sitemap

A sitemap lists all pages. An IA diagram shows structural relationships, hierarchy, and navigation patterns between content areas. IA answers how does this relate to that rather than just what pages exist.

Creating IA after the screens are designed

IA should be the first design artifact. If you design screens before defining the IA, you get disconnected screens that each make local sense but create a confusing overall structure.

No hierarchy distinction

Using the same shape and color for all hierarchy levels makes the diagram unreadable. Use size, color, and indentation to visually communicate hierarchy. Level 1 items should look visually heavier than level 3 items.

Tips

Use FigJam for the initial IA brainstorm, then migrate the finalized structure to Figma for the precise diagram

Run a card sorting exercise with users before finalizing the IA to validate your category labels

Version the IA diagram by duplicating the page each time you make major structural changes

Conduct a tree testing session using Optimal Workshop Treejack to validate navigation findability before building

How Vantage helps

Vantage connects product requirements to technical structure. When you import a Figma IA diagram as context in Vantage, the AI references the navigation structure when generating PRDs and tickets. Navigation architecture decisions translate directly into frontend component requirements in the generated ticket set.
