These limits apply on a per-property basis. You can increase certain limits (but not event/parameter character limits) by upgrading your property to Google Analytics 360 . For configuration limits, see this article instead.
Collection limits
Google Analytics doesn't log events, event parameters, and user properties that exceed the following limits. For example, Analytics doesn't process the 26th user property nor does it process an event name with more than 40 characters.
For detailed information about the error events that Analytics logs when you exceed the following collection limits, see Analytics Error Codes .
Distinctly named events
There is not limit on the number of distinctly named events for web data streams.
500 per app user
(for app data streams)
You might see more than 500 distinctly named events if users on different app instances trigger different events.
Automatically collected events and enhanced measurement events don't count toward the limits.
100 characters
The following exceptions apply:
- the page_title parameter must be 300 characters or fewer
- the page_referrer parameter must be 420 characters or fewer
- the page_location parameters must be 1,000 characters or fewer
Character limits
The character limits are the same for single-width character languages (e.g., English) and double-width character languages (e.g., Japanese). The encoded URL character length is used when counting character limits.
