LCP decides how fast your site feels. Julian Jandl breaks down what it is, how it works, and what to do if it’s too slow.
📊 Understanding LCP – Largest Contentful Paint
Julian Jandl from Push-Based has published a detailed article on the performance metric LCP – Largest Contentful Paint.
It’s one of the three Core Web Vitals by Google, the other two being INP (Interaction to Next Paint) and CLS (Cumulative Layout Shift).
LCP is important because it measures when the largest visible element on the page finishes rendering.
According to Julian, this matters because once that largest element is displayed, users typically perceive the website as "ready to use".
Ideally, LCP should happen within 2.5 seconds of the page starting to load.
🧠 How does LCP work?
The browser keeps watching the page as it loads.
Once the user starts interacting, or the page is fully loaded, the browser picks the largest visible element in the viewport – that becomes the LCP.
That’s why it’s crucial to:
- Know*which element is likely to be the LCP on your page
- Make sure that element loads as quickly as possible
In many cases, the LCP is an image (e.g. a hero image), but it can also be a text block like a headline or intro paragraph.
🛠 Practical Tips
Julian’s article isn’t just theory – it includes real examples, dev tools, and a solid explanation of how LCP works.
He also links to CrUX (Chrome User Experience Report) resources, so you can check how your own site is performing based on real-world usage data.

📉 A Quiet Week, Except for Signal Forms
Other than that, last week was quite calm in the Angular world.
That said, we’ve seen a continued surge in community content around Signal Forms – blog posts, tutorials, and YouTube videos.
