View Your Visitors Browser Size in Google Analytics

As Kiwi businesses continue shifting more of their marketing efforts online, understanding how customers interact with your website has never been more important. One often overlooked - but critical - aspect of user experience is browser size: what portion of your website is actually visible on screen without scrolling. This has meaningful impact on your conversion rate.

What is Browser Size

Your customers are using an ever-growing number of devices. Many users are on mobile platforms, and although desktop monitors are getting bigger, browsers aren't necessarily following suit. For many people, the visible portion of the web page is much smaller than the screen resolution, because of excessive toolbars and other clutter. This can have a significant effect on your website conversion rates. See how we provide a solution for this by building responsive websites.

Why should you care? Because if your key content—like CTAs, contact forms, or limited-time offers—sits “below the fold” (i.e. out of immediate view), many visitors might miss it. That could be costing you valuable leads or sales.

Google Analytics now provides a visualization that lets you quickly determine which portions of your page are visible to which percentages of visitors. For example, are your customers scrolling down to view the special deal you have on house painting this month?

How to view Browser Size in Google Analytics 4 (GA4)

Here’s how to view what users see when they land on your pages:

1. Use the “Pages and Screens” report. Go to Reports > Engagement > Pages and screens to see performance for specific URLs.
2. Visualise heatmaps with third-party tools. GA4 no longer includes a native browser-size heatmap, but you can integrate tools like Microsoft Clarity, Hotjar, or Lucky Orange for detailed visual behaviour reports. These show you scroll depth, clicks, and what content gets the most attention.
3. Scroll tracking with Google Tag Manager. For a custom setup, you can track how far users scroll using Google Tag Manager and GA4 events. This helps you measure exactly how many people reach certain points on your page - like testimonials, pricing, or your main call-to-action.

Why Browser Size (and Scroll Behaviour) Matters for NZ Businesses

Small and medium businesses across New Zealand - from tradies to retailers to local service providers - need to capture attention fast. If users don’t instantly see what you offer or how to get in touch, they might leave before taking action.

• Mobile-first design is non-negotiable. Over 70% of NZ web traffic is now mobile. Your site must prioritise fast-loading, responsive layouts that surface key info above the fold.
• Above-the-fold real estate drives conversions. Make sure your primary CTA (book now, get a quote, contact us) is visible right away—no scrolling needed.
• User behaviour insights = better decisions. When you know where users stop scrolling or drop off, you can adjust layouts and content to better meet their needs.

Not sure how your site performs across different screen sizes - or if you're still transitioning from Universal Analytics to GA4?
