How Many Hours Does It Take to Design a Website in 2025? (A Data-Driven Breakdown)

As a “Chief Everything Officer,” you need a new website, and you need a straight answer. When you ask, “How many hours does it take to design a website?” you’re met with the single most frustrating answer in business:

“It depends.”

It’s a frustrating answer because it’s true, but it’s also useless for budgeting. You can’t plan a project, hire an agency, or even decide to do it yourself based on “it depends.”

As an agency that builds high-performance websites, we live in spreadsheets and project plans. The “it depends” answer isn’t good enough for us, and it isn’t good enough for you.

This post gives you the data. We are breaking down the real hours it takes to build a website in 2025, from the first discovery call to the final launch.

Key Takeaways 

The Short Answer: Average Website Build Times (in Hours)

Let’s get right to the data. The total time depends on three things: the type of site, the number of pages, and who builds it.

Here is a breakdown of the typical total professional hours (from an agency or freelancer) required for a new website.

The DIY Question: What about doing it yourself on Squarespace or Wix?

For a 10-page small business site, set aside 60 to 100 hours of your own time.

Now, let’s break down why it takes this long.

What are the main phases of a website design project?

A professional web design and development project isn’t just one “design” task. It’s a 5-phase process. Skipping any of these steps is how you end up with a beautiful site that doesn’t get you any customers.

Phase 1: Discovery & Strategy (10-20% of total hours)

This is the most important and most overlooked phase. It’s the “blueprint” phase.

• What it is: Kick-off meetings, competitor analysis, defining your target audience, clarifying your goals (e.g., “generate 20 leads per month”), and planning the site structure (sitemap).
• Why it matters: This is where we ensure we’re building the right website, not just a pretty one.

Phase 2: UI/UX Design (20-30% of total hours)

This is what most people think of as “design.”

• What it is: First, we create User Experience (UX) wireframes—basic, black-and-white layouts that focus on the user’s journey. Once you approve that “skeleton,” we move to User Interface (UI) design, which is the full-color, branded “skin,” including fonts, colors, and imagery.
• Why it matters: UX makes the site easy to use. UI makes the site beautiful. You need both.

Phase 3: Content & SEO Strategy (The #1 Bottleneck)

We list this as its own phase because it’s the #1 reason projects get delayed.

• What it is: Writing all the text (copy) for every single page. This also includes a foundational SEO services strategy, like keyword research and optimizing page titles.
• Why it matters: You cannot build a house without materials. We cannot build your website without your content. A 10-page website needs 10 pages of high-quality, approved text before development can be finalized.

Phase 4: Development & Coding (30-40% of total hours)

This is where the approved design files are turned into a real, functional website.

• What it is: Writing the HTML, CSS, and JavaScript, setting up the Content Management System (CMS) like WordPress, and making the site “responsive” (so it works on mobile).
• Why it matters: This is the “construction” phase. It’s highly technical and is the most time-intensive part of the project.

Phase 5: Testing, Revisions & Launch (10-15% of total hours)

You don’t just “flip a switch.”

• What it is: A quality assurance (QA) team tests the site on all browsers (Chrome, Safari) and devices (iPhones, Androids, desktops) to find bugs. We also check all forms, links, and set up your analytics.
• Why it matters: A launch with a broken “Contact” form is a disaster. Testing ensures a smooth, professional launch day.

What are the key factors that influence a website design timeline?

The table above provides a baseline. Your project’s timeline will shrink or expand based on these 4 factors:

1. Complexity of Features: A simple “brochure” site is fast. Do you need online booking? A secure client portal? A real-estate MLS feed? A 500-product eCommerce store? Each new piece of functionality adds research, design, development, and testing hours.
2. Number of Pages: A 10-page site will take at least twice as long as a 5-page site. It’s not just 5 extra pages; it’s 5 extra pages of content, design, development, and testing.
3. Custom vs. Template: A custom-coded website built from scratch will always take longer (and deliver a better result) than a pre-built template.
4. Content & Feedback (The Client Factor): The single biggest variable in a website timeline is the client. If you deliver all your content (text and photos) on time and provide feedback within 24-48 hours, your project will fly. If the agency has to wait 2 weeks for you to write the “About Us” page, the entire project grinds to a halt.

How long does it take to build different types of websites?

Let’s apply the 5-phase model to real-world examples.

• Landing Page (1 Page): Total 18-35 Hours

• Goal: Convert traffic for a single campaign (e.g., a webinar).
• Time: Strategy is minimal (5 hours), design is focused (10 hours), and development is self-contained (15 hours). This can be done in 1-2 weeks.

• Small Business Website (10-20 Pages): Total 90-140 Hours

• Goal: Act as the 24/7 digital storefront for a service business.
• Time: This is the “standard” build. It requires a full strategy (20 hours), custom design for 5-7 unique page templates (40 hours), and significant development and testing (70 hours). The average timeline is 6-10 weeks.

• eCommerce Website (Small Store, 50 Products): Total 150-230+ Hours
• Goal: Securely sell products online.
• Time: Everything is more complex. Strategy includes payment gateways and shipping logic. Design includes the cart, checkout, and product pages. Development is highly complex, involving security, databases, and integrations. This is a 10-16 week minimum project.

How does using a website builder vs. a custom build affect the timeline?

This is the classic “DIY vs. Pro” question.

DIY Website Builder (Wix, Squarespace)

• Timeline: 60-100 hours (of your time).
• The Pro: It’s “faster” to get something live because you’re skipping the custom design and coding.
• The Con: You are now the strategist, designer, copywriter, and developer. The “opportunity cost” is massive. If your billable rate is $200/hour, spending 80 hours on a DIY website just “cost” you $16,000 in lost revenue. You also risk a generic, low-performance site.

Custom Agency Build

• Timeline: 90-140 hours (of our time).
• The Pro: You are only responsible for providing content and feedback. You get a team of 5-7 experts (strategist, designer, developer, copywriter, SEO) focused on building a high-performance, unique asset.
• The Con: It requires a larger cash investment and you’re on a 6-10 week timeline.

What is the difference between UI/UX design and development time?

This is a common point of confusion that impacts the timeline.

• UI/UX Design Time (Phases 1-2): This is the planning and design part. It’s the “blueprint” and the “interior design.” The final deliverable is a picture of the website (e.g., a Figma or Adobe XD file). This takes 40-60 hours.
• Development Time (Phase 4): This is the construction part. It’s the developer taking that “picture” and using code to build a real, working, clickable house. This takes 60-90+ hours.

A client will often say, “The design is done, why is it taking 4 more weeks?” It’s because the “design” (the picture) is just the starting line for the “development” (the build).

How can “scope creep” delay a website project?

“Scope creep” is the #1 project-killer. It’s a “Chief Everything Officer’s” worst nightmare, whether you’re the client or the provider.

• What it is: When the project’s goals and deliverables “creep” outwards after the project has started.
• The Example: The project is in the final development phase, and a stakeholder says:

• “You know, we really should add a blog.”
• “Can we add a 5-step booking form here? It’s just a form.”
• “I decided I don’t like the ‘About Us’ page structure. Let’s redesign it.”

These “small” changes seem simple, but they can add dozens of hours, forcing the project to go back to the design, development, and testing phases. To avoid it, you must have a rock-solid Phase 1: Strategy and a signed-off project scope.

Here is a helpful video from HubSpot on how they plan a website in-house, which heavily emphasizes the “planning” (Phase 1) part of the process.

Frequently Asked Questions (FAQ)

Can you build a simple website in a day?

You can get a one-page “brochure” live on a template-builder in 8-10 hours, if you have all your content, photos, and domain ready to go. A professional, custom website? No, it’s impossible to do the 5-phase process in a day.

How long does a 10-page website take to build?

For a professional agency, a custom 10-page website takes between 90 and 140 total hours, spread across a 6 to 10-week timeline. If you’re doing it yourself, budget 60-100 hours of your own time.

What is the fastest way to get a website live?

1. Use a template on a website builder (like Squarespace).
2. Have 100% of your content (text and photos) written and collected before you start.
3. Launch a single “Coming Soon” landing page. This can be done in 2-3 hours and gives you a professional presence while you build the full site.

How much time should be dedicated to testing a website?

Our agency dedicates 10-15% of the total project time to testing. For a 100-hour project, that’s 10-15 hours of a dedicated Quality Assurance (QA) person trying to “break” the site. This is non-negotiable for a professional launch.

What information do I need to prepare to speed up the website design process?

This is the most important question you can ask. If you have this ready before you hire an agency, you will be their favorite client and your project will fly.

1. Content: The written text for every page (Home, About, Service 1, Service 2, Contact).
2. Photos: Your logo file and any high-quality, professional photos of your team or products.
3. Examples: 3-5 links to websites you like (and why) and websites you hate (and why).
4. Logins: Access to your domain registrar (where you bought your .com).

The Time Is an Investment, Not a Cost

Viewing your website in “hours” is smart, but the real metric is value.

A 10-hour DIY site that cost you $50 but brings in zero leads is a failed investment. A 120-hour, $15,000 agency website that brings in $50,000 in new business in its first year is one of the best investments you’ll ever make.

The time it takes to build a website is directly proportional to the quality of the asset you’re building.

At 12AM Agency, we don’t build “fast” websites. We build strategic assets designed to grow your business. If you’re ready to invest the time to do it right, we’re the partners to help you.
