What Is Largest Contentful Paint
Largest Contentful Paint (LCP) is one of the key metrics in Google’s Core Web Vitals. It measures how long it takes for the main content of a web page to become visible to users.
In simple terms, it tracks when the largest visible element, such as a hero image, heading, or featured post grid, appears on the screen.
A good LCP score indicates that your page’s main content loads quickly, improving the overall website’s user experience.
According to Google PageSpeed Insights, a good LCP should occur within 2.5 seconds of when the page starts loading. If your LCP is higher than that, you may have issues such as render-blocking resources, slow server response time, unoptimized images, or large CSS and JavaScript files.
How to Find Largest Contentful Paint
Finding the Largest Contentful Paint is simple. All you need to do is use a platform like Google PageSpeed Insights or GT Metrix. For this blog post, we will be using the PSI tool to find the data.
The first step is to visit Google PageSpeed Insights. There, enter your website’s URL and start analyzing.

The process will take some time. So, wait for it to complete. Once the test is finished, you can view your score.

As you can see, we have got a 2.7-second score.
That is it!
This is how you can find the Largest Contentful Paint score of your website.
What Is a Good Largest Contentful Paint Score
A good LCP score helps ensure a fast-loading WordPress page and a better website’s user experience. Google recommends the following benchmarks:
| LCP Score | User Experience | Notes |
|---|---|---|
| 0 – 2.5 seconds | Good | LCP element loads quickly; passes Core Web Vitals. |
| 2.5 – 4.0 seconds | Needs Improvement | Users may notice delay; optimize hero images, render-blocking CSS, or server response time. |
