Google Analytics 4 Limits and Quotas is a new aspect of GA4 that will test some users with data collection and reviewing. These limits are only relevant to this property and are on a per-property basis.

Keep in mind that GA4 will not log events and event parameters that exceed Google Analytics limits.

Are you still using a Universal Property?

If you are still using the Universal Analytics property, either through Google Analytics or Google Analytics 360, and haven’t updated to GA4, then you can find the Universal Analytics limits and quotas here.

(We recommend creating a GA4 property alongside your existing Universal property to gain access to some of the new features available in GA4).

What are your Google Analytics 4 Limits?

GA4 lets you track an almost infinite number of parameters with events but you will not be able to access all of them from the interface. You will need to pick your top 50 text parameters to map as custom dimensions in the reporting UI.
