What is LCP by browser auto-translate
LCP by browser auto-translate reveals how Largest Contentful Paint (LCP) behaves depending on whether the browser automatically translated the page or not.
Modern browsers like Chrome offer automatic translation for pages detected to be in a different language than the user’s preference. While this improves accessibility, it may affect rendering timing
Healthy LCP by browser auto-translate sample
Should you worry
In a healthy state - both translated and non-translated experiences have green LCP values. This is a sign your layout is stable and your content renders smoothly even when browser translation is layered on top.
Unhealthy LCP by browser auto-translate sample
If auto translated pages have worse LCP:
It could be due to reflows or re-layouts caused by changes in text length or structure post-translation.
Some JavaScript frameworks may wait for translated content before completing render or interaction phases.
The mismatch can lead to delays, especially for languages with longer words or different character sets.
On the other hand, if non-translated LCP is slower, it might point to more fundamental performance issues in the default version — often affecting most users.
Either way, a gap between the two is worth examining.
