Is my hero CTA above the fold on all common device sizes?

As an e-commerce business owner, I'm concerned about my website's conversion potential and want to ensure that my primary call-to-action (CTA) is immediately visible to visitors across different devices. I need to understand how to optimize my hero section's layout to maximize visibility, engagement, and potential conversions without requiring users to scroll. What are the best practices for positioning and designing an above-the-fold hero CTA that works seamlessly on mobile, tablet, and desktop?

TL;DR - Quick Answer

Check on 375px (iPhone SE), 390px (iPhone 14), 360px (Android common), and 768px (tablet) viewports. Your hero CTA should be fully visible without scrolling on all of these. If it's below the fold even on one common size, you're losing first-impression conversions.

Is My Hero CTA Above the Fold on All Common Device Sizes?

Above-the-fold visibility for your primary call-to-action is one of the highest-impact conversion factors on your homepage and key landing pages. If a shopper lands and doesn't see a clear action to take without scrolling, you're losing a significant percentage of first-time visitors who won't bother.

Samsung Galaxy A360px~640pxCritical
iPad (portrait)768px~954pxHigh
Desktop 12801280px~800pxMedium

Common Causes of Below-Fold CTA

  • Hero image too tall on mobile (vh-based height)
  • Announcement bar + header + hero headline = no room
  • Large headline font pushing CTA down
  • Multiple lines of sub-headline text before button
  • Excessive padding/margin on hero container

Fixes

  • Cap hero height: max-height: 80svh on mobile
  • Shorten headline to 5-7 words on mobile
  • Use min-height instead of fixed heights
  • Test with Chrome DevTools at 375px viewport
  • Use Google PageSpeed screenshot to see actual fold

Growth Suite Tip

Growth Suite's Trigger Campaigns can show a targeted offer when a visitor scrolls past a set point. But if your hero CTA is already above the fold and compelling, you may not need the trigger on the homepage at all - save urgency mechanics for product and cart pages where decision friction is highest.
