The Problem

Your Site Looks Fine on a Laptop, Then Falls Apart on Phones

The problem shows up when most of your visitors arrive on phones, but the site was designed on a desktop screen and squeezed down later.

  1. 01 · Zoom

    Visitors pinch and scroll sideways to read a single paragraph.

    Layouts reflow to one column at 320px, so text reads without zooming.

  2. 02 · Menus

    The mobile menu hides links or won't open on touch.

    We rebuild navigation for thumbs, with tap targets that meet WCAG 2.2 size rules.

  3. 03 · Forms

    Quote forms run off the screen and open the wrong keyboard.

    Fields stack, and email and phone inputs open the matching mobile keyboard.

  4. 04 · Images

    Phones download full desktop photos, so pages load slowly.

    Responsive images serve smaller files to smaller screens.

A customer taps your ad on the train, and your homepage loads as a tiny desktop page. They pinch to zoom, the menu hides behind an icon that won't open, and the quote form's submit button sits off the edge of the screen. Your 3-column service grid shrinks to text the size of a footnote. They close the tab and call the next business in the results. You don't see it happen, because on your laptop everything looks fine.

We start with your analytics: which devices and screen widths your visitors use, and which pages they land on. Then we set breakpoints where your content breaks, not at generic device sizes, and rebuild layouts mobile-first with fluid grids, flexible type, and images sized for each screen. Every template gets tested on real phones and tablets before launch. You fix the design once, instead of patching it device by device.

  • Breakpoints set by content

    Layouts change where your content needs them to, not at a list of popular phone widths.

  • Tested on real devices

    iPhones, Android phones, and tablets, plus BrowserStack for the models we don't keep in the office.

  • Images sized per screen

    srcset and modern formats, so phones download small files instead of desktop-sized photos.

Our Responsive Web Design Services Process

From Mobile Review to Every-Screen Launch in Five Clear Steps

You see the screen widths your visitors use, approve the layouts for phone and desktop, and test the staging site on your own phone before anything goes live.

  1. We open your key pages at 6 screen widths, check your analytics for real device use, and run Lighthouse on mobile. You get a list of what breaks where, which templates need work, and the plan that fits.

What's Included

What You Get With Our Responsive Website Design Services

A responsive version of your site that keeps your content and URLs. Layouts, navigation, images, and forms get rebuilt for phones, tablets, and desktops, with test results to prove it.

  • Breakpoint layout plan

    A map of every template with phone, tablet, and desktop layouts you approve before the build starts.

  • Thumb-friendly navigation

    Menus, buttons, and links resized and spaced so visitors tap the right thing the first time.

  • Responsive images

    srcset, sizes, and WebP or AVIF files, so each screen downloads an image that fits it.

  • Forms that fit phones

    Stacked fields, readable labels, and email and phone inputs that open the right mobile keyboard.

  • Reflow and tap checks

    Pages checked against WCAG 2.1 reflow at 320 pixels and the WCAG 2.2 minimum target size.

  • Device test report

    Results for every template on real devices and BrowserStack, in portrait and landscape views.

Projects We've Built

Websites we designed and built to work on phones, tablets, and desktop screens, from a medical practice and a restaurant to course and travel platforms.

What Our Clients Say

What Clients Say After Launch

Feedback from teams we have designed and built websites for.

We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture

Why Teams Choose Us to Make Their Sites Responsive

What we do differently as a responsive design company: we design from the smallest screen up and test on the devices your visitors actually use.

  • Smallest screen first

    We design the 320px layout before the desktop one. Content that works in a narrow column usually works wider, and the reverse is rarely true.

  • Your analytics, not averages

    We check which devices and widths your visitors use before setting breakpoints. A B2B site with desktop buyers and a restaurant full of phone visitors need different priorities.

  • Real thumbs, real taps

    We test menus and buttons by tapping them on actual phones, not just by shrinking a browser window. Emulators miss tap targets that sit too close together.

  • Honest about templates

    If a modern responsive theme already fits your brand, we'll tell you before we quote. Custom responsive work makes sense when your design or features are worth keeping.

  • Speed counts on mobile

    Phones on cellular connections feel every extra image and script. We size images per screen and cut unused CSS while we rebuild the templates.

  • You own the result

    Code, Figma files, and device test results are yours at handover. Any developer can maintain the responsive templates after we finish.

Good fit

  • Sites built before mobile mattered

    Your site was built before mobile responsive web design was standard, and on phones visitors still see a shrunken desktop page.

  • WordPress sites with a dated theme

    Your WordPress theme is old, but your design and content still work, and you'd rather adapt the layouts than start over.

  • Businesses losing mobile leads

    Your analytics show most visitors arrive on phones, yet almost every quote request comes from desktop, and you suspect the mobile form.

  • Webflow or Next.js sites with layout bugs

    Your Webflow or Next.js site breaks at tablet width, with overlapping text and images pushed off screen at certain sizes.

  • Agencies short on front-end time

    You sold a client a mobile refresh and need a responsive website development company to rebuild the templates under your brand.

Not a fit

  • Whole site needs rethinking

    Your content, structure, and branding all need rethinking, not just the layout. Website Redesign Services plans the new site first, then builds it responsive.

  • No real website yet

    You don't have a website yet, or it's a one-page placeholder. Small Business Website Design Services builds a new responsive site from the start.

  • Budget under $850

    You only need one page fixed, such as a single landing page. A freelancer or your theme's built-in mobile settings will cost less than our smallest plan.

  • Store pages and cart

    Your mobile problem is a Shopify or WooCommerce store's product pages and cart. Ecommerce Website Design Services covers store templates and checkout flows.

FAQ

Frequently Asked Questions

Straight answers on cost, timelines, how responsive layouts work, and what they do for SEO.

  • Making your site responsive starts at $850 for up to 5 key templates on your current site. Responsive Rebuild costs $2,400 for up to 15 templates, and Mobile-First Redesign starts at $5,200 for a new design across up to 25 pages. The price depends on your template count, how the current CSS is written, and whether you want a new design.

  • Most projects take 1 to 6 weeks. Converting up to 5 templates takes about 1 to 2 weeks, a 15-template rebuild about 3 to 4 weeks, and a full mobile-first redesign 5 to 6 weeks. Device testing is part of every timeline, and your content stays live on the current site until launch day.

  • Responsive web design is building one website whose layout adapts to the screen it's viewed on, from a small phone to a wide monitor. It relies on fluid grids, flexible images, and CSS media queries, an approach Ethan Marcotte named in A List Apart in 2010. The same HTML and URL serve every device, and the CSS decides the arrangement.

  • It means every visitor gets the same site and content, arranged to fit their screen. On a phone, your menu folds into a button, columns stack, and buttons grow to an easy tap size. On a laptop, the same page spreads into columns. There's no separate mobile site to update, so one edit changes every version.

  • It works through CSS that reacts to available space: fluid grids, media queries, and container queries that change layouts at widths called breakpoints. The viewport meta tag tells phones to use the device width instead of a zoomed-out desktop view. Images use srcset, so a phone downloads a smaller file than a large monitor does.

  • It matters because visitors judge your business on the screen in their hand. A layout that needs pinching and sideways scrolling loses enquiries and makes forms hard to finish. It also supports accessibility: WCAG 2.1 asks content to reflow at 320 CSS pixels wide without scrolling in two directions, and responsive layouts meet that by design.

  • It helps SEO because Google uses the mobile version of a page for indexing and ranking, which it calls mobile-first indexing. One responsive URL also avoids the duplicate pages and split links a separate mobile site can create. Google Search Central recommends responsive design as the easiest pattern to implement and maintain.

  • The purpose is one site that works well on every screen, with no separate versions to build and maintain. Visitors get readable text, tappable buttons, and forms that fit, whatever device they use. You get one codebase, one set of URLs, and one place to edit content, which keeps design and upkeep costs down over time.

  • Visitors on any device see a layout built for their screen, and you update one site instead of two. In practice that means no pinch-zoom, menus that work with a thumb, images sized for the screen, and email or phone fields that open the right keyboard. Your analytics also show one set of numbers for every device.

  • Yes, every plan includes fixes after launch: 14 days on Responsive Fix, 30 days on Responsive Rebuild, and 45 days on Mobile-First Redesign. We fix any layout bug on the devices in your test list. You own the code and design files, and a responsive web design company you hire later can pick them up without us.
