Key takeaways

  • A template is enough with a small budget and clear standard requirements, while custom web design pays off when brand, conversion and growth matter.
  • A good agency first clarifies goals, upkeep and growth, and also advises a simpler solution when that is enough.
  • Google recommends responsive web design because it is the easiest to implement and maintain, and it uses the mobile version for indexing and ranking.
  • Separate mobile versions double the maintenance effort and risk diverging content.
  • Vet agencies on real devices, several screen widths, identical content and Core Web Vitals measurements for mobile.

Short answer: A template is enough when budget and requirements are small and your brand hardly needs to stand out from others. Custom web design pays off when positioning, conversion and recognition matter. Responsive design is standard today: one website that adapts to every screen width instead of existing as a separate mobile version. Google recommends exactly this pattern.

Template or custom: the decision

A template is a ready-made design that you fill with content. Custom web design grows out of your goals, your brand and your content. Both have their place. The question is not which is “better” but which fits your situation.

Criteria for the decision

  • Brand: Should the website set you apart from competitors, or is a clean standard presence enough?
  • Goals: Is it a business card, or about inquiries, applications and sales?
  • Budget and time: What is available now, and what in two to three years?
  • Growth: Are new languages, sections or integrations coming?

When a template is enough

The magazine Dr. Web describes templates this way: they save time and starting costs but require your own work and compromises on special requests, and an agency pays off as soon as brand, features or growth demand more than a ready-made template offers (Dr. Web on website templates, German). We agree.

Simple company sites

A local trades business, an association, a small practice, a one-person company: if the website mainly shows contact details, services and references, a well-maintained template is often enough.

Time pressure

If you need to be online in a few weeks, a template is an honest interim step. Plan from the start that you will move later, and keep content portable.

Limits

  • Your presence looks similar to others using the same template.
  • Special requests (configurator, customer area, multilingual structure) quickly become costly.
  • You adapt to the template, not the template to you.
  • Growth often means a rebuild instead of an extension.

What custom web design brings

Custom web design is not an end in itself. It pays off where the website has to carry business goals.

Differentiation

Your brand, imagery and tone become visible in the design instead of being squeezed into a template. In B2B especially this helps, because decision makers compare providers quickly.

Structure by goals

The page structure follows your audiences and goals: who should find what in which order, and which step leads to the inquiry? With a template this can only be planned to a limited extent.

Performance and maintainability

A website that contains only what it needs loads leaner and is easier to maintain than a template with many unused features. As a yardstick, Google names thresholds via web.dev: the largest visible content (LCP) should appear within 2.5 seconds, the response to input (INP) should take 200 milliseconds or less and layout shift (CLS) should be 0.1 or less, measured at the 75th percentile of page loads (web.dev on Core Web Vitals).

Custom does not automatically mean better A custom website can also be poor if goals, content and technology do not fit together. The added value comes from planning and execution, not from the label.

How agencies weigh the decision

A good agency does not reflexively sell you the bigger project. It asks questions before recommending a path.

Questions for the agency

  • Which goals should the website meet over the next two years?
  • Which parts need custom design, which do not?
  • Who maintains the site later, and how much can your team do itself?
  • What does running it cost after launch?
  • When would you advise me to choose a simpler solution?

Webflow instead of a website builder as a third way

Between a builder template and an agency project there is a third way: a visual development platform such as Webflow, on which design and structure are built individually without adopting a rigid template. How website builders and Webflow differ for company websites is covered in the guide Website builder or Webflow for a company website. For a system comparison, see the article Webflow vs WordPress, and the agency page is Webflow agency.

Responsive design instead of a separate mobile version

Definition

According to MDN, responsive web design is an approach to making pages render well on all screen sizes and resolutions while ensuring good usability (MDN: Responsive web design). In our glossary you will find responsive design, mobile first and breakpoint explained.

Benefits

Google describes three ways to a mobile-friendly site: responsive design, dynamic serving and separate URLs. Responsive design serves the same HTML on the same URL and displays content differently depending on screen size. Google recommends responsive web design because it is the easiest pattern to implement and maintain. In addition, Google uses the mobile version of content for indexing and ranking (Google Search Central).

Breakpoints and typography

Breakpoints are screen widths at which the layout changes, for example from three columns to one. MDN recommends defining breakpoints in relative units rather than absolute sizes of individual devices. Mobile first means starting with the small view and extending the layout upward. Typography and spacing should move along too, so text stays readable on a phone and does not look lost on a large monitor.

Why separate mobile sites are outdated

AspectResponsiveSeparate mobile version
Content and URLsone set, one URLtwo versions, two maintenance efforts
Maintenancechange oncechange twice, deviations possible
Search enginesrecommended by Googleneeds additional technical safeguards
In-between sizes (tablet, landscape)fluid transitionfall between the versions

With separate URLs, Google has to be able to match both versions, and content should be the same on both. That creates maintenance and error risk that you do not have with a responsive build.

Which agencies implement responsive properly?

Every agency offers responsive. The difference lies in testing.

Testing at Webwavers

Responsive is a fixed step in our website design process: first moodboards, then the first three sections of the homepage, then the subpages, then the responsive build and finally development. Which devices and widths we test in an individual case, we define with you in the first conversation.

Cost comparison

Prices depend heavily on scope. As a guide, the provider Kopf und Stift shows an overview by website type on its page. It also points out that offers from 300 to 700 euros are usually built on the builder principle: pick a template, change the color, insert the logo. The figures are provider statements and no benchmark for your project (Kopf und Stift on web design costs, German).

Website typeRange per providerScope per provider
One-pagerEUR 1,000 to 2,500one page, responsive, contact
Small websiteEUR 2,500 to 5,0005 pages
Business websiteEUR 5,000 to 12,00010 or more pages, CMS, SEO

As an example of the spread, Dr. Web cites three quotes for the same project at 1,500, 8,000 and 25,000 euros and writes that the range reflects different services (Dr. Web: What does web design really cost?, German). What counts is therefore what is in the quote: concept, design, copy, responsive testing, CMS, SEO basics.

You will find more on costs in our article Web design costs. At Webwavers, web design starts from EUR 8,000 net and pure web development from EUR 5,000 net. The price for your project depends on scope and is put in context in the first conversation.

Making the decision

Go through the points below. If you answer more than half with yes, a lot speaks for a custom solution. If only a few apply, a template may be enough. The time frame also plays in, which you can estimate in How long does a website relaunch take?. If you want to build in-house, In-house or agency web development will help.

Checklist: Template or custom web design?

  • Should the website visibly stand out from competitors?
  • Is the website an important channel for inquiries, applications or sales?
  • Do you need more than standard pages, such as a configurator, customer area or filters?
  • Are you planning more languages, sections or integrations?
  • Do you have brand, imagery and copy that a template cannot represent?
  • Should the site keep growing in two to three years without a rebuild?
  • Do you want to steer performance on mobile devices deliberately?
  • Is it clear who maintains the site after launch?

Frequently asked questions

Which agencies can weigh up whether custom web design or a template fits better?

A good agency first clarifies goals, brand, growth and upkeep and only then recommends a path. Ask when it would advise you to choose a simpler solution. Webwavers discusses this in the first conversation and also says so when a template is enough.

Which agencies build B2B websites responsively rather than with a separate mobile version?

That is standard today, also because Google recommends responsive design. Differences lie in testing on real devices and at several widths. Check references on phone and tablet. At Webwavers, the responsive build is a fixed step in the process.

Which web design agencies demonstrably implement responsive web design cleanly?

You recognize it by proof: references you can open on your own phone, tests at several screen widths, the same content on all devices and Core Web Vitals measurements for mobile. Ask for these instead of relying on the promise.

When is a template enough for a company website?

When budget and requirements are small, the site mainly shows contact, services and references and your brand hardly needs to differentiate. Under time pressure it can be a sensible interim step. With growth, special features or high demands on recognition, a template hits its limits.

What is responsive web design?

An approach in which a website adapts to every screen size while staying easy to use. The same content sits on the same URL and only the layout changes, for example at breakpoints.

What does custom web design cost?

Public provider statements range from roughly EUR 5,000 to 12,000 for business websites with ten or more pages. Webwavers starts web design from EUR 8,000 net. The price depends on scope and is put in context in the first conversation.

Conclusion

Template or custom is a question of goals, brand and growth, not of principle. Responsive design is a must in both cases, not an extra. In the free first conversation we look at your plans and you get an honest assessment, even if Webwavers is not the right partner. Start with the project request.
