Largest Contentful Paint Element: How to Fix It (Step-by-Step Guide)

Website speed is no longer optional. It directly affects user experience, conversion rates, and search rankings. One of the most important performance metrics today is Largest Contentful Paint (LCP) — a core part of Google’s Core Web Vitals. If you want to understand how LCP, CLS, and INP work together as ranking signals, read our complete guide to Core Web Vitals in 2026.

What Is Largest Contentful Paint (LCP)?

Largest Contentful Paint measures how long it takes for the largest visible content element on the page to load.

This usually includes:

  • A hero image

  • A large banner image

  • A background image

  • A big block of text (like an H1 heading)

Google measures LCP from the moment the page starts loading until that largest element becomes visible inside the viewport.

Good LCP Score According to Google

  • Good: 2.5 seconds or less

  • Needs Improvement: 2.5 – 4.0 seconds

  • Poor: Over 4.0 seconds

If your page crosses 2.5 seconds, optimization is required.

What Is the Largest Contentful Paint Element?

The LCP element is the largest visible element within the viewport when the page loads.

It can be:

  1. <img> element

  2. <image> inside SVG

  3. <video> poster image

  4. Background image loaded via CSS

  5. Block-level text elements

In most websites, the LCP element is the hero image at the top of the page.

Why Is Your LCP Slow?

Before fixing it, you must understand what causes poor LCP.

Google identifies four main causes:

1. Slow Server Response Time (High TTFB)

  • If your server responds slowly, everything loads late.

2. Render-Blocking Resources

  • CSS and JavaScript files that block rendering delay LCP.

3. Large Images

  • Uncompressed images increase loading time.

4. Client-Side Rendering

  • Heavy JavaScript frameworks may delay rendering.

Now let’s move to the practical solution.

Largest Contentful Paint Element: How to Fix It

Below is a structured, proven method to improve LCP.

Step 1: Identify the LCP Element

Use:

  • Google PageSpeed Insights

  • Lighthouse (Chrome DevTools)

In the report, look under:

“Largest Contentful Paint element”

It will show the exact element causing delay.

You must optimize that specific element — not random parts of the page.

Step 2: Optimize the LCP Image

If your LCP element is an image, follow these steps:

✔ Compress the Image

Use modern formats:

  • WebP

  • AVIF

These provide smaller file sizes compared to JPEG or PNG.

✔ Resize Properly

Do not upload a 3000px image if it displays at 1200px.

Match the image dimensions to the container size.

✔ Serve Responsive Images

Use srcset and sizes attributes so browsers load the correct size.

Step 3: Preload the LCP Element

If the browser discovers the LCP image too late, it delays loading.

Use:

<link rel=“preload” as=“image” href=“hero-image.webp”>

 Preloading tells the browser:

“Load this image immediately.”

This significantly reduces LCP time.

Step 4: Remove Lazy Loading from LCP Image

Lazy loading is good — but not for the LCP element.

If your hero image has:

loading=”lazy”

Remove it.

LCP images should load immediately, not lazily.

Step 5: Reduce Server Response Time (TTFB)

High Time To First Byte increases LCP.

To fix:

  • Use fast hosting

  • Enable server-level caching

  • Use a CDN

  • Upgrade PHP version (for WordPress users)

A faster server improves overall performance.

Step 6: Eliminate Render-Blocking CSS and JS

Heavy CSS and JavaScript delay rendering.

Fix this by:

  • Minifying CSS and JS

  • Deferring non-critical JavaScript

  • Removing unused CSS

  • Using critical CSS

Critical CSS ensures above-the-fold content loads first.

Step 7: Optimize Fonts

If your LCP element is text, web fonts may cause delay.

To fix:

  • Use font-display: swap

  • Preload important fonts

  • Reduce font weights

Example:

				
					</> css

@font-face {
  font-display: swap;
}

This prevents text from staying invisible while fonts load.

Step 8: Avoid Large Background Images in CSS

If your hero section uses a CSS background image:

				
					</> css
background-image: url("hero.jpg");

Browsers discover it late because it loads after CSS.

Instead:

  • Use an <img> tag where possible

  • Or preload the background image

Background images often cause LCP load delay.

Step 9: Improve Mobile LCP

Mobile networks are slower.

To optimize:

  • Reduce image size further

  • Use adaptive images

  • Avoid heavy animations

  • Reduce third-party scripts

Mobile performance affects rankings more than desktop.

Common LCP Issues and Fixes

Here are frequent warnings and solutions:

“Largest Contentful Paint image was lazily loaded”

Fix: Remove lazy loading from that image.

“Largest Contentful Paint element is text”

Fix:

  • Optimize fonts

  • Reduce render-blocking CSS

  • Improve server response

“Largest Contentful Paint element image”

Fix:

  • Compress image

  • Preload it

  • Remove lazy loading

“Largest Contentful Paint load delay”

Fix:

  • Preload image

  • Reduce CSS blocking

  • Remove heavy JS

WordPress Users: Special Optimization Tips

If you use WordPress:

  • Use performance plugins with CSS/JS optimization

  • Disable lazy loading for the hero image

  • Enable object caching

  • Optimize images before uploading

Many themes add heavy sliders — avoid them for better LCP.

How to Measure LCP After Fixing

Always retest using:

  • Google PageSpeed Insights

  • Chrome Lighthouse

  • Real-user data (Core Web Vitals report in Search Console)

Lab results may differ from real-world results. Focus on real user data for accurate performance measurement.

Conclusion

Fixing the Largest Contentful Paint element is not complicated when you follow a structured process.

Most websites struggle with LCP because of:

  • Heavy hero images

  • Poor hosting

  • Render-blocking CSS and JavaScript

  • Improper lazy loading

By identifying the exact LCP element and optimizing it directly, you can significantly improve loading speed, user experience, and search rankings.

If your goal is better performance, higher conversions, and stronger SEO results, optimizing LCP should be your top priority.

1. What is a good Largest Contentful Paint score?

A good Largest Contentful Paint (LCP) score is 2.5 seconds or less. According to Google’s Core Web Vitals guidelines, a page is considered good if the LCP occurs within 2.5 seconds of when the page first starts loading. If the score falls between 2.5 and 4 seconds, it needs improvement. Anything above 4 seconds is considered poor and requires immediate optimization. If your LCP is above 2.5 seconds, you should start improving your page performance.

2. What is usually the LCP element on a website?

In most websites, the LCP element is the hero image that appears at the top of the page. It can also be a large banner image, a background image loaded through CSS, or a prominent heading such as the main H1 text. The LCP element is simply the largest visible element inside the user’s viewport during initial page load. You can check the exact element in Google PageSpeed Insights under the section labeled “Largest Contentful Paint element.”

3. Why is my LCP high even after image optimization?

If your LCP remains high after compressing and resizing images, the problem may not be the image file itself. A slow server response time, also known as high TTFB (Time to First Byte), can delay rendering. Render-blocking CSS files, heavy JavaScript execution, web fonts that delay text visibility, or excessive third-party scripts can also increase LCP. Largest Contentful Paint is not only about image size; it measures how quickly the browser can fully render the main visible element.

4. Does lazy loading affect LCP?

Yes, lazy loading can negatively affect LCP if it is applied to the main LCP image. When an image is set to loading="lazy", the browser delays loading it until it is needed. Since the LCP element should load immediately, lazy loading it increases the LCP time. The largest content element must load as early as possible to achieve a good score.

6. Is LCP more important on mobile or desktop?

LCP is important on both devices, but mobile performance is generally more critical. Google uses mobile-first indexing, which means it primarily evaluates the mobile version of your website for ranking purposes. Since mobile networks are often slower than desktop connections, optimizing LCP for mobile users has a stronger impact on search visibility and user experience. Always test your mobile performance separately.
