How to check your own website on a phone

Most people who check their own website do it on the same laptop they built it on, over a fast office connection, with a mouse. That is nearly the opposite of how most visitors actually arrive: on a phone, on mobile data, with a thumb. A site can look finished on a 27-inch monitor and be genuinely unusable at 390 pixels wide. The good news is that checking properly takes about ten minutes and needs nothing but the phone already in your pocket.

Open the menu with your thumb

Hold the phone the way you normally would, one-handed, and try to open the navigation menu without adjusting your grip. A menu icon in the top corner that needs a stretch or a second hand is friction on every single page view. While the menu is open, check that it closes again the same way, and that tapping a link actually navigates rather than requiring a second tap because the first one only opened a sub-menu.

Find the price or the main offer without scrolling sideways

Load your homepage and your main service or product page and look for the thing you most want a visitor to see: a price, a headline offer, a call-to-action. It should be readable without turning the phone sideways or pinching to zoom. If you find yourself scrolling right as well as down, a table, a wide image or a fixed-width element is wider than the screen, which on a phone usually means an element was given a fixed pixel width instead of one that adapts.

Look for headings and buttons breaking mid-word

Scan every heading on the page. A long word — a full company name, a technical term, a compound noun — can break awkwardly across two lines on a narrow screen even when it looked fine on desktop, because desktop had far more horizontal room to work with. The same applies to button labels: a button sized for a six-word desktop label can wrap onto two lines and look broken at phone width. Buttons and links should also be large enough to hit accurately with a thumb tip, not just a stylus — anything smaller than roughly the size of a fingertip invites a mis-tap on the wrong link.

Test the contact form's keyboard

Open your contact form and tap into each field in turn. An email field should bring up a keyboard with @ and .com shortcuts; a phone field should bring up the numeric keypad; a general text field should bring up the ordinary keyboard. If every field brings up the same generic keyboard, the form was built without telling the browser what kind of information each field expects, which makes typing an email address on a phone noticeably slower than it needs to be.

Check nothing sits under the browser bar

Mobile browsers show and hide their own address bar as you scroll, which changes how much vertical space the page actually has. A fixed header, a sticky call-to-action button or a cookie banner that was positioned against the very edge of the screen can end up partly hidden underneath the browser's own bar, especially on iPhones with a home indicator at the bottom. Scroll up and down a few times on a page with a sticky element and watch whether anything gets obscured or clipped.

Try it in dark mode, and on mobile data

If your phone has a system dark mode switched on, some sites will follow it automatically. Check that text stays readable against its background either way — pale grey text that was subtle on a white background can disappear almost entirely on a dark one. Then turn Wi-Fi off and reload the site on mobile data, ideally somewhere the signal is not perfect. This is the test most owners skip, because their office Wi-Fi never lets them see what a slow connection does to their own images and layout.

• Open the menu one-handed and close it again
• Find the price or main offer without scrolling sideways
• Check headings and buttons for mid-word wrapping
• Confirm each form field brings up the right keyboard
• Watch for anything hidden under the browser's own bar
• Read it in dark mode if your phone uses one
• Reload it on mobile data, not office Wi-Fi

None of this requires special tools — a phone, ten minutes and a willingness to actually tap through your own site the way a stranger would is enough to catch most of what matters.

If several of these checks fail at once, that is usually a sign of an underlying template or platform problem rather than one page needing a fix — worth raising before it costs enquiries. For a free look at how your site performs on a phone, try our free website check.
