Figma for prototyping

Figma’s prototype mode lets you connect frames through interactions like click, hover, drag and scroll. Each connection defines a trigger (which user action activates it), an action (navigate, open overlay, swap) and a transition animation.

The power of this system is that you do not need to duplicate screens for every state. With components and variants, you can simulate state changes within the same screen, reducing file complexity and making maintenance easier.

Auto Layout is Figma’s flexible layout system that lets you build components that adapt to their content, much like CSS Flexbox. Elements inside an auto layout frame redistribute automatically when size or content changes.

For prototyping, auto layout is essential because it simulates real responsive behaviour. A menu that grows as items are added, a form that dynamically shows error fields, or a list that expands with scroll — all become possible through auto layout combined with variants.

Figma’s component system lets you create reusable elements with multiple variants. For prototyping, this means defining every state of a button (default, hover, pressed, disabled), a form field (empty, filled, error) or a card (collapsed, expanded) within a single component.

The "Change to" interaction in prototype mode allows switching between variants without changing frames. This is what makes it possible to simulate complex interactions like toggles, accordions, tabs and dropdowns within a single screen.

Figma variables let you store and manipulate values during prototype interaction. You can create variables of type string, number, boolean or colour and modify them through conditional actions.

This unlocks possibilities that previously required code: a cart counter that updates when products are added, a form that shows or hides sections based on previous selections, or an onboarding flow that adapts to user responses. Variables transform a prototype from a linear sequence of screens into an interactive experience with real logic.

Smart Animate is Figma’s intelligent animation feature. It detects elements with the same name across two frames and automatically animates differences in position, size, rotation, opacity and colour.

It is especially useful for transitions that communicate the relationship between states: a card expanding into a detail view, a menu sliding in from the side, or a progress indicator advancing smoothly. The key is keeping layer names consistent across frames so Smart Animate recognises them as the same element.

Figma’s plugin ecosystem extends its prototyping capabilities with features the tool does not offer out of the box. From realistic data to interactive maps, the right plugins dramatically speed up your workflow.

A mature Figma prototyping workflow follows a clear progression: wireframes with auto layout → components with state variants → prototype connections with interactions → variables for conditional logic → Smart Animate for transitions.

Organise your file with separate pages for wireframes, visual design and prototype. Use a local component page or, better yet, a shared design system as a library. This ensures consistency and facilitates collaboration between designers, handoff to development and future iterations.
