For answers to these and other questions, see " Largest Contentful Paint" on web.dev. Largest Contentful Paint attempts to provide more meaningful data by using the largest content element as a proxy for when the main content of the page is likely visible to users. At the time of the first contentful paint, there's no content on screen that a user can interact with. Consider the example below, taken from a DevTools performance audit.
Some metrics are only measurable in a lab, while others tell nothing about content that users care about. The usefulness of existing metrics varies. It has not always been easy for developers to measure how quickly the main content of a web page loads and is visible to users.
