5 Mobile Website Problems That Are Easy to Miss on a Desktop

You checked your website on your laptop. It looked great. Then a client texted you a screenshot from her phone, and your heart sank. Buttons were overlapping. Text was tiny. That beautiful layout you paid for? On mobile, it looked like a scrambled egg.

This happens to almost every woman solopreneur I talk to. You build a website on desktop, it feels solid, and then you realize mobile is a completely different animal. The frustrating part isn’t that mobile is hard, it’s that you can’t see the problems until someone points them out. And by then, potential clients have already left.

Here’s the thing: mobile is not a nice-to-have anymore. Half your visitors, probably more, are on phones. But here’s what’s easy to miss, I make it easy to check these five things so your mobile experience actually works for your business.

The Gap Between What You See and What Clients See

When you’re building or reviewing your website on a desktop, you’re in a totally different world than the person visiting on their phone. Your screen is big. Your mouse is precise. You can see everything at once. Your client is on her lunch break, phone in one hand, coffee in the other, trying to figure out if she should hire you. The experience has to work for her, not for your laptop.

This isn’t a failure on your part. This is just how it works. And once you know what to look for, it gets so much easier to spot.

1. Buttons That Are Impossible to Tap

On desktop, a button looks perfectly fine at 12 pixels wide. On mobile, it becomes a tiny target that’s basically impossible to hit without zooming in or getting frustrated.

I see this constantly, especially on contact forms or “Book a Call” buttons. The button exists, but it’s so small that people give up before they even try. Or worse, they tap it three times and hit something else instead.

What to look for: Open your website on your phone. Try to tap every button, link, and call-to-action without zooming in. If you have to think about it or if your finger keeps missing, your visitors will too.

The opportunity here: Make buttons at least 44 pixels tall and wide, this is the standard for mobile. That might sound big on desktop, but on phone, it’s just right. Your visitors will actually be able to click what you want them to click.

2. Text That’s Too Small to Read Without Squinting

This is the one that makes me cringe the most, because it’s so easy to happen. You design something that looks good on your monitor, set the font size to 14 pixels, and never check it on an actual phone.

Then your client looks at it on her iPhone and has to zoom in just to read your About section.

Here’s the hard truth: if someone has to zoom to read your website, they won’t. They’ll just leave. Phone browsers have made it so you can zoom, sure, but people don’t want to. They’re already half-distracted. You’re asking them to do extra work, and they won’t.

What to look for: Open your website on your phone in portrait mode. Can you read every piece of text, headings, body copy, navigation menu, even the small stuff in your footer, without zooming? If you’re squinting, so will your clients.

The opportunity: Bump up your body text to at least 16 pixels on mobile. Your headings should be even bigger. Yes, it looks different on desktop. That’s okay. That’s what responsive design is for.

3. Navigation Menus That Don’t Work on Touch Screens

Desktop navigation often relies on hover effects. You put your mouse over a menu item, and a dropdown appears. Beautiful. Elegant. Totally broken on mobile.

Here’s why: on a phone, there’s no hover. There’s just tap. So when someone taps your menu, they either get nothing, or they get a dropdown menu that covers half the screen and they can’t close it easily.

A lot of business owners I work with have hamburger menus (those three little lines) that look clean, but once you open them, the experience falls apart. Text runs off the screen. Links are hard to tap. It feels janky.

What to look for: Open your website on mobile and try to navigate using the menu. Can you easily see all your options? Can you tap on a link without accidentally hitting something else? Does the menu close easily?

The opportunity: Make sure your mobile menu is clean, tappable, and easy to close. If you have dropdown menus, they should work on touch screens without being fussy. Test it yourself. If you have to think about how to use your own menu, visitors definitely will.

4. Forms That Are Too Wide or Have Tiny Input Fields

I see a lot of contact forms on mobile that are basically unusable. The input fields are narrow. Labels sit on top of fields in a way that doesn’t match how people actually fill out forms. Sometimes the form is so wide that you have to scroll left and right to fill it out.

On mobile, there’s no room for awkwardness. Form fields should be full width, easy to see, and simple to fill out with a thumb.

What to look for: Open your contact form on mobile. Try filling it out without zooming. Can you see the label and the input field at the same time? Is the field wide enough to see what you’re typing? Does the form feel natural, or does it feel cramped?

The opportunity: Make your form fields full width on mobile. Make labels clear and close to their fields. Test it with actual data, don’t just look at it, actually fill it out. What feels clunky to you will feel impossible to someone on a small screen.

5. Images and Videos That Break the Layout

This one sneaks up on you because it usually works fine when you’re designing. But sometimes on mobile, images get too big, or they don’t scale properly, and suddenly the whole layout shifts. Text wraps weird. Buttons move. The page feels broken.

Videos are the same. A video that looks perfect on desktop can push the mobile layout completely out of balance, or it won’t even load, or it’s so zoomed in you can only see a corner of it.

What to look for: Scroll through your entire website on mobile, top to bottom. Watch for images that are distorted, stretched, or too big for the screen. Check any videos, do they play? Do they fit? Are they a reasonable size?

The opportunity: Make sure all your images scale properly on mobile. Use something called responsive images if you can (your web designer should handle this). For videos, make sure they’re embedded in a way that scales automatically. Test everything on different phone sizes, iPhone, Android, whatever you use.

How to Actually Check Your Mobile Site (Without Losing Your Mind)

You don’t need fancy tools or screenshots. Just grab your phone, go to your website in a browser, and look at it. Scroll around. Try the buttons. Fill out a form if you have one. This is the most honest way to see what your visitors see.

If you want to get more technical, every browser has mobile inspection tools. But honestly? For most solopreneurs, your actual phone is the best tool. Use it. Spend five minutes looking at your site on mobile. You’ll spot things right away.

And here’s the thing, knowing what to look for makes this so much faster. You’re not trying to redesign the whole thing. You’re just checking: are the buttons tappable? Is the text readable? Does the form work? Do images stay in their place? Does navigation make sense?

That’s it.

Why This Matters (Beyond the Technical Stuff)

Look, the real reason your mobile website needs to work is this: your clients are on their phones. They’re busy. They’re distracted. They have about ten seconds to decide if they want to keep reading or move on. If your website makes them work harder, even a little bit, they’ll leave.

But when your mobile site works smoothly, something shifts. They can read your story. They can tap your button. They can fill out your form without feeling annoyed. And suddenly, you don’t look like someone with an outdated website. You look like someone who actually cares about making things easy for her clients.

That’s the opportunity here. Your website should feel like you, and it should work beautifully whether someone’s looking at it on a laptop at 11pm or on their phone at a stoplight. Both deserve the same respect.

If you’ve built your website on desktop and haven’t really looked at it on mobile, spend 10 minutes today checking these five things. You might find it’s already solid. Or you might see something that’s worth fixing. Either way, you’ll know.

And if you want someone to do this detective work with you, or if you’re not sure what you’re looking at on your phone, that’s what I’m here for.

Frequently Asked Questions

Do I need to hire someone to fix mobile problems?

Not necessarily. Some things you can fix yourself, like making text bigger or adjusting button sizes if you have access to your website editor. Other things, like making images responsive or fixing layout issues, might need someone with code knowledge. It depends on the problem and your comfort level.

Can I use my tablet to check my mobile site?

A tablet is better than nothing, but not ideal. The real test is an actual phone, because the screen is much smaller and that’s where most of your traffic probably comes from anyway. Spend a few minutes on your phone, that’s your actual customer experience.

What if I don’t know what I’m looking at when I check my mobile site?

That’s totally normal and not a sign you’re doing something wrong. Tech is a language, and nobody was born speaking it. Start by just looking at basics: can you read the text? Can you tap the buttons? Does it feel easy or frustrating? That gut feeling matters.

Should I be checking my mobile site on WiFi or cellular?

Both, honestly. WiFi is faster, so load times might look better than they actually are for someone on cellular. If your site feels slow on cellular, that’s something worth knowing about. But for checking layouts and tappability, either one works fine.
