Wireframe: What is a wireframe?

What is a wireframe?

A wireframe is a simplified, schematic representation of the structure of a web page or application screen. It is a greyscale visual blueprint that defines the placement of key elements: content areas, navigation menus, action buttons, forms and images. A wireframe does not concern itself with the final visual design (colours, typography, imagery); it focuses exclusively on spatial organisation and information hierarchy.

The wireframe is the first tangible step in the UX design process. It enables project teams, designers and clients to agree on the structure of a page before investing time and resources in graphic design. At Kern-IT, within the KERNWEB division, every web project begins with a wireframing phase in Figma, ensuring that the interface foundations are solid before moving to high-fidelity design.

Why wireframes matter

Wireframes play a fundamental role in the success of a digital project. They allow structural hypotheses to be validated early in the process, when changes are still inexpensive.

• Content clarity: a wireframe forces you to define precisely which content appears on each page and in what order. This upfront thinking prevents late-stage reorganisations that delay projects.
• Stakeholder alignment: sharing a wireframe with a client is far more tangible than a written specification. It enables precise, constructive feedback from the earliest phases of the project.
• Cost reduction: modifying a wireframe takes minutes; modifying a high-fidelity mockup takes hours. Iterating on wireframes saves significantly on the overall design budget.
• Usability focus: by eliminating visual distractions, the wireframe forces the team to concentrate on navigation logic, information hierarchy and user flows.
• Foundation for prototyping: wireframes serve as the basis for interactive prototypes that will be tested with real users.

How it works

The wireframe creation process follows a methodical approach that moves from strategy to a structured visual representation. At Kern-IT, we distinguish three levels of fidelity.

Low-fidelity wireframes are quick sketches, often drawn by hand or built with simple geometric shapes. They allow rapid exploration of multiple layout options without committing to details. These are ideation tools used during scoping workshops with clients.

Medium-fidelity wireframes are created in Figma and introduce more precision: real block dimensions, realistic placeholder text, typographic hierarchy (headings, subheadings, paragraphs) and indication of primary interactions. This is the level most commonly used by the KERNWEB team at Kern-IT, as it strikes a good balance between production speed and communication clarity.

High-fidelity wireframes approach the final mockup in terms of precision but remain in greyscale. They include real content, precise spacing and detailed annotations for developers. This level is reserved for complex projects that require very detailed technical specifications.

Regardless of the fidelity level, a wireframe documents the layout grid, visual hierarchy, clickable areas and interaction points.

Concrete example

The KERNWEB team at Kern-IT is tasked with designing a new website for a Brussels-based fintech company. The site must present financial products, display a credit simulator and convert visitors into leads via a contact form.

Before opening Figma, the team organises a scoping workshop with the client to define the priority content for each page. The homepage is wireframed at medium fidelity: a hero section with a value proposition and primary call-to-action button, a three-column key benefits section, a testimonials block, quick access to the simulator and a final call to action.

The wireframe is shared with the client via a Figma link. Two iterations are enough to validate the structure: the client asks to move the simulator block above the testimonials and add a trust bar with banking partner logos. These changes take 15 minutes to implement. The validated wireframe then serves as the foundation for visual design and subsequent development on Wagtail CMS with Tailwind CSS.

Implementation steps

1. Content inventory: list all content elements required for each page (headings, text, images, forms, buttons).
2. Grid definition: choose a layout grid (12 columns is the standard) to structure element placement.
3. Quick sketch: produce paper sketches or low-fidelity wireframes to explore several layout options.
4. Digital wireframe: create a medium-fidelity wireframe in Figma, placing content blocks, navigation areas and interaction points.
5. Annotation: add explanatory notes describing interactive behaviours (dropdown menus, accordions, modals) and content rules (character limits, dynamic content).
6. Review and iterate: share the wireframe with stakeholders, gather feedback and iterate until sign-off.

Related technologies and tools

• Figma: the primary tool used by Kern-IT for collaborative wireframing, prototyping and design. Wireframes can be turned into interactive prototypes directly within the tool.
• Tailwind CSS: the utility-first CSS framework that allows structures defined in wireframes to be quickly translated into front-end components, thanks to its flexible grid system.
• Wagtail CMS: the Django-based CMS whose StreamField blocks naturally correspond to the blocks identified in wireframes, easing the transition from wireframe to functioning site.

Conclusion

The wireframe is the fundamental tool of any user-centred design approach. By separating structure from visual design, it allows interface foundations to be validated quickly and affordably. At Kern-IT, the KERNWEB division systematically includes a wireframing phase in its web projects, ensuring that every Wagtail site rests on a well-considered page architecture that has been approved by the client before a single line of code is written.
