Row limits apply to the database tables that populate the reports you see in Google Analytics. These limits determine the maximum number of rows that can appear in a report.
What are the row limits
A standard report uses a custom database table that includes only the data needed for the report. The row limit for the table for most standard reports is 50,000 rows.
When you apply a secondary dimension or comparison to a report, you increase the likelihood of data aggregating in an "(other)" row.
For standard properties, all standard reports with a secondary dimension or comparison applied and all custom reports use a database table that includes all the dimensions in your property for the specified date range. The row limit for this table is 2 million rows.
For Analytics 360 properties, all reports are eligible to trigger a custom table automatically. Custom tables also have a row limit of 2 million rows, but the table will only include the dimensions needed for the report, rather than all of the dimensions collect in the property.
When a report reaches the limit
When the underlying table of a report reaches the row limit, Analytics aggregates the excess rows under an "(other)" row. When this happens, Analytics provides approximate results in the dimension breakdowns because some dimension values are aggregated under the "(other)" row. However, the metric totals for all the data are correct. Learn more
