A design brief is a short document that tells your designer what you need, who it’s for, and what success looks like, before any work starts. A good one saves weeks of back-and-forth, prevents expensive revisions, and gives your designer everything they need to do their best work. Here’s how to write one, plus a free template you can use today.
Key takeaways
- A brief isn’t a creative restriction. It’s the constraint that makes good work possible.
- Most project delays trace back to a vague or missing brief, not to the design itself.
- You don’t need design experience to write a good brief. You need clarity on your goals.
- One clear page beats a ten-page brief nobody reads.
- Grab the free template near the end and fill it in before your next project.
A design project without a brief is a road trip with no destination. You’ll end up somewhere, it just won’t be where you needed to go. After running dozens of web and UX projects, I can tell you the single biggest predictor of a smooth one isn’t budget or timeline. It’s whether the brief was clear on day one.
What is a design brief?
A design brief is a written document that outlines the goals, requirements, and context for a design project. It’s usually written by the client (you) and reviewed by the designer before work starts. Think of it as the shared reference both sides come back to when a decision gets fuzzy.
It’s not a contract, and it’s not a creative brief in the advertising sense (that’s more about campaign messaging). It’s a practical alignment tool: who this is for, what it needs to do, and what “done well” looks like.
Why bother writing one?
Because the alternative is expensive. Without a brief, designers make assumptions, and some of those assumptions will be wrong. You get a first draft that’s not quite right, you request changes, you get another draft, you request more, and three rounds later you’ve spent the budget a good brief would have protected.
A brief also forces you to get clear on what you actually want. That process of writing it down surfaces the gaps and disagreements you didn’t know you had. Better to find them now than halfway through the project. Once your brief is ready, it also makes it far easier to choose the right web designer, because you can judge them against clear goals instead of a vague wish list.
| Vague brief says… | Clear brief says… |
|---|---|
| “Make it modern and clean.” | “Minimal layout, lots of white space, like Stripe or Linear. Here are three sites I like and why.” |
| “We want more traffic.” | “Grow enquiry-form submissions 20% in 90 days from organic search.” |
| “A website for our business.” | “A 6-page site on WordPress + Elementor, mobile-first, integrating with HubSpot.” |
| “You’re the expert, do your thing.” | “Here’s our brand, our audience, and the one action every page should drive.” |
What to include in a design brief
You don’t need all of these for every project, but a strong brief covers most of them.
1. Project overview
One or two sentences on what you’re building and why. “A new marketing site to replace our 2018 WordPress build and drive more qualified leads.” This is the north star everything else hangs off.
2. Business and brand background
Who you are, what you sell, and what makes you different. If you have brand guidelines (logo, colours, fonts, tone of voice), attach them. If you don’t, describe your brand in plain language. Words like “professional but approachable” give a designer a useful starting point.
3. Target audience
Who’s this for? Be specific. “Everyone’ isn’t a target audience. A designer who understands your audience makes better calls on layout, tone, and hierarchy.
4. Goals and success criteria
What does success look like, in numbers if possible? “A nice website” isn’t a goal. “20% more enquiries within 90 days of launch” is. This is the line that keeps the whole project honest.
5. Scope and deliverables
List the specifics: number of pages, file formats, versions (desktop and mobile), and anything explicitly out of scope. Naming what you’re not paying for prevents the awkward “I thought that was included” conversation later.

Three to five examples you like, and one line on why for each. Also share what you don’t like. Both directions calibrate a designer to your taste faster than any adjective.
7. Technical requirements
Platform (WordPress, Shopify, custom), integrations, existing tools, browser or device support. The earlier a designer knows the constraints, the fewer surprises at build time.
8. Timeline and budget
A hard deadline and the real reason behind it (a trade show, a product launch, a season). And a budget range, even a rough one. Hiding the budget doesn’t get you a lower price, it just wastes both sides’ time scoping the wrong thing. If you want a second pair of eyes before you send it, get in touch and we can walk through it together.
Common brief mistakes to avoid
Too long. A brief that runs to twenty pages will get skimmed. Keep it to one or two. Put supporting material in attachments.
Too vague. “Modern and clean” describes half the internet. Push yourself to be specific about brands you admire and the feeling you want.
No clear goal. If the brief doesn’t say what success looks like, every design decision becomes a guess.
Leaving out constraints. Budget limits, technical rules, brand rules that can’t be broken. Tell the designer upfront. Constraints found halfway through are the ones that hurt.
The best briefs aren’t the longest. They’re the ones that make the next decision obvious.
Frequently asked questions
How long should a design brief be?
One to two pages for most projects. The goal is clarity, not completeness. If you have supporting docs like brand guidelines or analytics, attach them separately rather than stuffing everything into the brief itself.
Who writes the design brief, the client or the designer?
Usually the client, because you know your business and goals best. A good designer will help refine it, and many (including us) will build it with you on a first call if you’re not sure where to start.
What if I don’t know my budget yet?
Give a range. “Somewhere between X and Y” is enough for a designer to scope the right solution. A budget helps them recommend what’s realistic instead of guessing high or low.
Do I need a design brief for a small project?
Yes, though it can be shorter. Even a few clear sentences on goal, audience, and must-haves will save you a revision round. The brief scales with the project.
What’s the difference between a design brief and a creative brief?
A design brief focuses on a specific design deliverable (a website, an app, a layout). A creative brief is broader and more common in advertising, covering campaign messaging and concept. For web and UX work, you want a design brief.
