How long a web design project takes depends on three things: what you're building, how quickly you respond to requests, and how the agency runs its process. Here's what to expect in practice.

Small business websites, typically 5 to 10 pages, usually take 4 to 8 weeks. That covers discovery, design, development, content integration, and testing. Nothing exotic, but it still takes time to do properly.

Mid-sized sites in the 10 to 30 page range run 8 to 14 weeks. The extra time comes from more complex design systems and CMS configuration, not just more pages.

E-commerce is where timelines stretch. Product catalogs, payment gateways, security configurations, and checkout UX all add up. Budget 12 to 24 weeks for a standard online store.

Enterprise sites and custom web applications are a different category entirely. If you need custom back-end development, API integrations, or anything non-standard, plan for 6 to 12 months minimum.

What actually blows up timelines, in rough order of frequency:

• Slow feedback from the client. This is the number one reason projects run late, and it's almost never the agency's fault.

• Missing content. Agencies can't design around placeholder text forever. If your copy and images aren't ready, the project stalls.

• Scope creep. Adding features mid-project costs more time than people expect, every time.

• Too many decision-makers. Every extra stakeholder adds at least one more round of revisions.

The agencies that consistently hit their deadlines aren't doing anything magical. They set milestones upfront, send clients a kickoff checklist before work starts, and use a formal change request process instead of just absorbing new requests on the fly. Tools like Asana, Monday.com, or ClickUp help, but only if everyone actually uses them. Weekly check-ins matter more than the software.

If your agency isn't doing these things, that's worth asking about before you sign anything.
