The verdict in three sentences
A serious redesign fits in 10 to 14 weeks, not three: scoping, design, development and testing chain together with firm sign-off milestones. Multilingual adds 2 to 3 weeks, e-commerce more. Every month of delay is paid in lost leads: a site generating 40 contacts/month loses roughly 10 leads for each week of slippage.
The typical redesign timeline
A credible plan breaks the project into phases with signed-off deliverables. Here are 2026 orders of magnitude for a business brochure site.
| Phase | Duration | Deliverable | Sign-off milestone |
|---|---|---|---|
| Scoping & content | 1-2 wks | Brief, sitemap | Scope sign-off |
| UX/UI design | 3-4 wks | Mockups 3-5 pages | Design approval |
| Development | 4-6 wks | Staging site | Functional review |
| Content integration | 1-2 wks | Filled pages | Content approved |
| Testing & SEO | 2 wks | Tests, redirects | Acceptance report |
| Go-live | 0.5 wk | Production site | Go-live |
Cumulative total: 10 to 14 weeks. Phases overlap partially, but the sign-off milestones are sequential: a late client approval shifts everything downstream.
What lengthens (or shortens) the timeline
Schedule slips rarely come from technology: they come from content and approvals. Let's quantify the main factors.
| Factor | Timeline impact | Common cause |
|---|---|---|
| Multilingual (FR/EN) | +2 to 3 weeks | Late translations |
| Content not ready | +2 to 4 weeks | Missing copy/visuals |
| Slow approvals | +1 to 3 weeks | Unclear decision path |
| Complex SEO migration | +1 to 2 weeks | Redirect plan |
| E-commerce / catalog | +3 to 6 weeks | Product pages, payment |
| Content ready upfront | -1 to 2 weeks | Good preparation |
The number-one lever to stay on schedule: prepare copy and visuals before kickoff and name a single approver on the client side.
Mini case study
David runs a 20-person consulting firm in Lyon and wants his redesign live before a trade show in 12 weeks. His current site generates 40 leads/month. He delivers content in week 1 and names a single approver: the project lands in 11 weeks. A competitor, delivering content late, slips by 6 weeks; at 40 leads/month, that is about 60 lost leads. With an 8% conversion rate and an average 6,000 EUR contract, the delay costs nearly 28,000 EUR in potential revenue not captured.

FAQ
How long does a website redesign take in 2026?
Expect 10 to 14 weeks for a business brochure site, from signature to go-live. Multilingual adds 2 to 3 weeks and e-commerce 3 to 6 weeks.
Why do projects run late?
In 70% of cases it is unready content and slow approvals, not technology. Preparing copy and visuals upfront is the best accelerator.
How much does a month of delay cost?
In lost leads: multiply your monthly generation by the delay. A 40-leads/month site slipping one month loses 40 opportunities.
Can a site be delivered in 3 weeks?
Yes for a standardized template with supplied content, but not for a custom redesign with dedicated UX. Too short a timeline is paid in quality or technical debt.
How do I secure sign-off milestones?
Name a single approver, set 48-72 h feedback deadlines and write them into the plan. Each late approval day pushes back go-live.
