About LCP and PageSpeed
Largest Contentful Paint measures when the main content becomes visible. It is a Core Web Vital and a key signal of perceived load speed. Use this estimator to identify which part of the load is slowest.
Quick guidance
- Keep hero images compressed and sized for the viewport.
- Preload critical assets and minimize render-blocking scripts.
- Use a CDN and caching to reduce server response time.
What is a good LCP score?
Good is 2.5s or less. 2.5s to 4s needs improvement, and above 4s is poor.
Is this a real performance test?
No. This is a planning estimator based on inputs. Use Lighthouse or PageSpeed Insights for lab testing.
What impacts LCP the most?
Slow server response, large hero images, and heavy render-blocking JavaScript are the most common causes.
