First Paint (FP)




DEFINITION: First Paint (FCP)

Defined by the Paint Timing API and available in Chrome M60+.

First Paint reports the time when the browser first rendered after navigation. This excludes the default background paint, but includes non-default background paint. This is the first key moment developers care about in page load – when the browser has started to render the page.
