INP (Interaction to Next Paint)

Quick Definition

INP measures responsiveness to user interactions like clicks and taps. The 'good' threshold is under 200 milliseconds.

In context

INP replaced FID in 2024 as a Core Web Vital. It captures the worst interaction delay during the entire session, not just the first one. Heavy JavaScript on the main thread is the typical culprit. Audit third-party scripts and defer non-critical JS to fix it.
