How to Write a Web Design Brief That Doesn't Suck
Most web design briefs are either three lines in an email or a 15-page document nobody reads. Here's how to write one that actually works.
I’ve received briefs that were three lines in an email: “We need a modern website. We like Apple. Budget is flexible.” I’ve also received briefs that were 15-page PDFs with mood boards, competitor analyses, and stakeholder interview transcripts that nobody on the team had actually read.
Both are useless.
A three-line brief gives you nothing to work with. A 15-page brief gives you everything except clarity. The perfect brief sits somewhere in the middle: specific enough to build from, short enough to actually reference throughout the project.
Here’s how to write one that works.
What a brief is and what it isn’t
A brief is not a wishlist. It’s not a mood board. It’s not a project plan.
A brief is a reference document that answers one question: what are we building and why? Every decision during the project should be checkable against the brief. “Should we add a chatbot?” Check the brief. “Should the homepage have a video background?” Check the brief.
If the brief doesn’t help you make decisions, it’s not a brief. It’s decoration.
The sections that matter
A good web design brief has seven sections. Not three, not fifteen. Seven.
Project overview
Two to three sentences that describe the project at the highest level. Who is the client, what do they do, what are they hiring you to build, and what’s the budget range?
This section exists so anyone who picks up the brief can understand the project in 10 seconds. You’ll reference it when onboarding subcontractors, when context-switching between projects, and when the client calls and you need to remember which project is theirs.
Key requirements
The specific, measurable deliverables. Not “build a great website.” Instead: implement a corporate minimal design aesthetic for a designer audience. Build e-commerce functionality with online transaction capability. Establish accessibility compliance across all pages. Coordinate SEO strategy with existing agency.
Each requirement should be concrete enough that you could check a box next to it when it’s done. If a requirement is vague (“make it user-friendly”), rewrite it until it’s specific (“page load time under 3 seconds on mobile”).
Four to six key requirements is the sweet spot. More than that and you’re writing a specification document, not a brief.
Risk flags
What could go wrong? Every project has risks. The honest brief acknowledges them upfront instead of pretending everything will go smoothly.
Common risk flags: unclear content requirements (the client hasn’t written their copy yet), undefined e-commerce scope (they want a shop but haven’t decided what they’re selling), no existing brand identity (you’re designing without guardrails), multiple decision makers (feedback will be slow and contradictory), aggressive timeline (not enough buffer for revisions).
Listing risks isn’t pessimistic. It’s professional. It shows the client you’ve thought through the project and it gives both of you a chance to address potential problems before they become actual problems.
Ask in meeting
These are the questions you need answered before starting. They’re the gaps in your knowledge that the intake form didn’t fully cover.
“What specific products are being sold, and which e-commerce features are essential for launch?” “Who is the primary decision maker for design approvals?” “Is the May 31 content deadline firm, or is there flexibility?”
Write these down and bring them to the kickoff meeting. Don’t start designing until they’re answered. Every unanswered question is a future revision or a scope dispute.
Recommended tech stack
Based on the project requirements, recommend the technology. CMS platform, hosting solution, third-party integrations, analytics tools.
This section prevents the mid-project conversation where the client says “Actually, can we use Shopify instead of WooCommerce?” You recommended the stack in the brief. They approved the brief. The stack is decided.
If you’re not sure about the tech stack, list two options with trade-offs and let the client decide. “Option A: WordPress with WooCommerce, lower cost, more plugins, requires more maintenance. Option B: Headless CMS with Saleor, higher initial cost, better performance, less maintenance.”
Content gaps
What’s missing? What does the client need to provide before you can start?
Service descriptions, product photography, team bios, testimonials, case studies, legal pages (privacy policy, terms of service). If the client hasn’t provided it and you’re not writing it, it needs to be listed here with a deadline.
Content gaps have a deadline for a reason. “Please provide homepage copy” is a wish. “Homepage copy due by April 15; delays will push the design phase by the equivalent number of days” is a project management tool.
Project timeline
Map the phases: discovery, design, revisions, development, testing, launch, handover. Give each phase a duration and a deliverable.
The timeline should match the payment schedule in the quote. Phase completion triggers a milestone payment. This creates accountability on both sides: you deliver on time, the client pays on time.
The brief nobody reads
Here’s the hard truth: clients don’t read briefs. Not because they don’t care, but because most briefs are formatted like legal documents. Dense paragraphs, jargon, and walls of text.
Format your brief for scanning. Use headers. Use short paragraphs. Lead with the most important information. If a section has more than four sentences, break it up.
The key requirements should be numbered, not buried in prose. The risk flags should stand out visually. The timeline should be a table, not a paragraph.
A brief that gets read is worth ten times more than a comprehensive brief that sits in a folder unopened.
When the brief changes
Projects evolve. Requirements shift. New information surfaces. That’s normal. But the brief should evolve with the project, not silently become irrelevant.
When the scope changes, update the brief. When a new requirement gets added, add it to the document with a note that it was added post-approval (and reference the change order that covers the additional cost).
The brief is a living document until the project is complete. It’s also the first thing you reference if there’s a disagreement about scope. “Here’s what we agreed to in the brief” ends most disputes before they start.
Writing the brief faster
The biggest obstacle to writing good briefs is time. You’re not getting paid to write documents. You’re getting paid to design and build websites. So the brief process needs to be fast.
The fastest approach: generate the brief from the intake answers. The client has already told you their business, goals, requirements, budget, and timeline in the intake form. Instead of rewriting all of that into a brief from scratch, use the intake answers as the raw material and structure them into the seven sections.
This turns brief writing from a 2-hour task into a 10-minute review. You’re editing and refining, not starting from a blank page.
debrieft generates structured briefs from client intake answers automatically. Key requirements, risk flags, meeting questions, recommended tech stack, and content gaps. All from one intake form. Your client gets a portal. You get a dashboard. Both in sync. Try it free at debrieft.app
