Figma library or PDF file: choose by team size.

PDF or Figma library: this question often arises when you have just completed the identity system and are thinking about implementation. The answer is not "which one is better" but "which one fits the way your team works." The two formats serve different purposes, and using the wrong one wastes both.

PDF and Figma library what's the difference

A standard PDF is a document for reading: designers read the guidelines, understand the principles, and then apply them using their tools. It is suitable when the team is small, when the designer has enough experience to build correctly, and when the product is primarily print or office documents.

The Figma library with components (reusable elements like buttons, info cards, navigation bars) is a document for direct use: designers pull existing components into their designs instead of building from a blank page. Its strength lies in the entire team using the same source, so when Sinh Vũ updates the primary color, all screens change simultaneously.

Factors that determine the selection

• Number of designers working together: This is the most important factor. When there are only one or two people, each can maintain consistency. When three or more people are involved in creating the interface, the likelihood of each person producing different styles increases significantly without a shared component source.
• Digital products or printed publications: The strongest Figma library is used for application and website interfaces. If most outputs are flyers, reports, packaging, PDFs with source files are usually sufficient.
• Does the team have someone to maintain it? The Figma library is a living asset. When the brand updates colors or adds new components, someone on the team needs to update the library accordingly. Without a responsible person, the library will diverge from the actual version running on the product after a few months.
• Long-term maintenance budget: Building a complete library requires effort to create and maintain. For a small team, this cost may not correspond to the benefits.

When to choose which direction

• Only need a PDF along with source files: a team of one to two designers, primarily producing print, without a dedicated person to maintain the design system, with budget priorities for other areas.
• Add a basic Figma library: there are three to four designers, needing to unify colors and typography, starting to create digital products but not frequently releasing features.
• Complete component Figma library: a large design team, collaboratively building a digital product, regularly releasing features, needing a common source of components for everyone to synchronize and reduce the time to recreate existing elements.

Documents for reading are not enough when multiple people are creating the interface. A reusable, synchronized library is needed so that the entire team can maintain consistency instead of each person having their own style.

Common errors

• Buy a premium library and then let it gather dust: If no one on the team updates it, after a few months the library will diverge from the actual product. At this point, designers start to ignore the library and create from scratch, completely losing the original purpose.
• Only deliver PDFs to a large team: each designer reads the PDF and interprets it in their own way, resulting in gradual deviation from the standard after a few months, especially in small elements like spacing, font size, button states.
• Confusing having components with completion: A component library addresses technical issues, but without accompanying rules and processes, designers may use the correct components in the wrong context. Both parts need to go together.

The viewpoint of Sinh Vũ

Sinh Vũ clearly divides deliverables: the basic version includes a PDF and a few editable source files, while the full version adds a Figma library with components, and the corporate level goes further into a digital asset management system. Sinh Vũ emphasizes finalizing levels based on how the client team actually operates, not defaulting to selling the thickest version just because it seems more professional.

If your team is small and the products are primarily printed, Sinh Vũ recommends that a PDF along with the source files is sufficient, saving the rest for other purposes. As the team grows and real needs arise, upgrading to a component library will still be timely and will provide a solid foundation.
