Interaction to Next Paint (INP)

A Core Web Vital measuring overall interaction responsiveness.

INP replaced First Input Delay (FID) in March 2024 and measures latency across all user interactions throughout a session. Good INP is under 200ms, needs improvement is 200-500ms, poor is above 500ms. Optimising INP requires reducing JavaScript main thread blocking, breaking up long tasks, deferring non-critical scripts and using event handlers efficiently.
