Why Does My Website Look Different on Mobile?

September 30, 20268 min read

Your website looks different on mobile because phones are narrow, and your site has to rearrange itself to fit. When that rearranging goes wrong, you see a tiny zoomed-out desktop page, text running off the screen, overlapping sections, or a layout that doesn't match what you designed. The most common causes are a missing viewport tag, elements with fixed widths, and website builders that keep a separate mobile layout. Here's how to find which one is affecting your site and fix it.

Quick diagnosis

  • Whole page is tiny and zoomed out: the viewport meta tag is missing.
  • You can scroll sideways / content is cut off: something has a fixed width wider than the phone.
  • Changes you made on desktop don't show on mobile: your builder (Wix, Squarespace, Canva) keeps a separate mobile layout.
  • Looks different on your phone than on someone else's: caching, browser dark mode, or the browser's text size setting.

The 8 causes and how to fix each

1

The viewport meta tag is missing

Most common on custom sites
Without this one line in your page's <head>, phones assume your site was built for desktop, render it at about 980px wide, and shrink it to fit. Everything looks tiny. Add: <meta name="viewport" content="width=device-width, initial-scale=1">. Website builders and modern themes include it automatically. If it's missing, a custom template or plugin has removed it.
2

Elements have fixed widths

A container, table, image, or embed set to a fixed pixel width (say width: 1200px) can't shrink to a 375px phone screen, so the page scrolls sideways and content gets cut off. Use relative widths (max-width: 100%, percentages) instead. Images and videos should always have max-width: 100%; height: auto. Embeds (maps, forms, videos) are frequent culprits because they often ship with fixed dimensions.
3

Your website builder has a separate mobile layout

Most common on builders
Wix has a dedicated mobile editor, Squarespace's Fluid Engine lets you arrange blocks separately for mobile, and Canva adapts designs for phones. That means edits made in the desktop view don't always carry over, and the mobile version can drift out of date. Switch the editor to its mobile view, review every section, and fix spacing and ordering there.
4

Responsive CSS (media queries) is hiding or rearranging content

Themes use CSS breakpoints to change the layout at certain widths. That's responsive design working as intended, but a badly written rule can hide sections, stack elements in the wrong order, or apply the wrong font size on phones. In Chrome, open DevTools (F12), click the device toolbar icon, and resize slowly. The width where the layout breaks tells you which breakpoint rule to look at.
5

Text is too big or wraps badly

Long words, large headings set in fixed pixel sizes, and buttons with long labels can overflow on narrow screens. Visitors who increase their phone's text size make this worse. Use responsive font sizes (clamp() or rem units), allow long words to wrap, and check your longest headings at 375px wide.
6

You're seeing an old cached version

If you just made changes and your phone still shows the old design, your browser or a CDN is serving a cached copy. Open the page in a private tab on your phone, or clear the browser cache. If you use a CDN or caching plugin, purge its cache after publishing.
7

The phone's browser is changing colors (dark mode)

Some mobile browsers, including Samsung Internet and Chrome with forced dark mode, can recolor websites automatically, making a light site look dark or making text hard to read. If your site looks different only on certain phones, check the browser's dark mode setting. As a site owner, you can define explicit dark-mode styles so browsers don't guess.
8

Different browser engines render it differently

Every browser on iPhone uses Apple's WebKit engine, so your site can behave differently on an iPhone than on an Android phone running Chrome. Some CSS works in Chrome but not Safari. If the problem only appears on iPhone, see our guide to fixing websites that don't work in Safari.

How to see your site the way phones do

Chrome DevTools device mode (quick, free)

Press F12, then Ctrl+Shift+M (Cmd+Shift+M on Mac), and pick a phone size. Good for spotting overflow and broken breakpoints fast, though it isn't a perfect copy of a real phone.

A real phone (most accurate)

Test on at least one iPhone and one Android phone, in a private tab. Tap every button and fill in every form. Emulators miss touch and keyboard issues.

An automated scan across screen sizes

BugSense renders your pages at 375px mobile, 768px tablet, and 1920px desktop and flags horizontal overflow, broken images, overlapping or covered elements, and layout failures on every page, so you don't have to check each page by hand. Run a free scan.

Should a website look the same on all devices?

No. It should work well on all devices, and that's different from looking identical. A good mobile layout stacks columns vertically, enlarges tap targets, and simplifies navigation into a menu. What should stay the same is your content, your branding, and the ability to complete every action (buying, booking, contacting you) on any screen. If a customer can't do something on their phone that they can do on desktop, that's a bug.

Why it matters: about 60% of web traffic now comes from phones (Statcounter, 2025), and in our scan of 10 successful online stores, 7 out of 10 had broken content on at least one device. Owners rarely spot these because they design and check on a laptop.

Seeing the mobile version on desktop (or the reverse)?

If you're a visitor and just want the full desktop layout on your phone: in Chrome on Android, tap the ⋮ menu and tick "Desktop site". On iPhone Safari, tap the "aA" button in the address bar and choose "Request Desktop Website". This changes how the site is shown to you only. It doesn't fix anything for the site's other visitors.

Frequently asked questions

Why does my website look different on mobile?

Phones are narrower than desktop screens, so your site has to rearrange itself. When it looks wrong, the usual causes are a missing viewport meta tag (the page appears tiny and zoomed out), elements with fixed pixel widths (sideways scrolling), a website builder's separate mobile layout that wasn't updated, or a cached old version.

How do I make my website look better on mobile?

Make sure the viewport meta tag is present, replace fixed widths with max-width: 100% and relative units, review your builder's mobile view section by section, use responsive font sizes, and test on real phones or with an automated scan at mobile, tablet and desktop sizes.

How do I change a website from mobile to normal view?

In Chrome on Android, open the ⋮ menu and enable "Desktop site". In Safari on iPhone, tap "aA" in the address bar and choose "Request Desktop Website". This only changes the view for you.

How do I make a website look the same on all devices?

Aim for consistent content and functionality rather than an identical layout. Use responsive design so columns stack on phones, keep branding and content the same, and make sure every action works on every screen size.

Why does my WordPress site look different on mobile?

Usually because of the theme's responsive CSS, a page builder's separate mobile settings (Elementor and similar builders have per-device controls), a plugin adding fixed-width content, or a caching plugin serving an old version. Check the page builder's mobile view and purge caches first.
