# Limits

Every limit here reports itself rather than failing silently. These are the numbers to plan around.

## Every limit

| **Limit**                  | **Value**                                | **What happens**                                                                                                                                                                                        |
| -------------------------- | ---------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Measurement ID format      | Must start with G- (GA4)                 | Universal Analytics IDs are accepted by the settings field but collect nothing anywhere.                                                                                                                |
| Custom dimensions created  | 14 (5 required, 9 optional)              | Against GA4's standard limit of 50 event-scoped custom dimensions. The app budgets 45 so you keep room for your own.                                                                                    |
| Report table page size     | 200 rows maximum, 50 by default          | Applies to the Content, Spaces, Searches and Raw tables.                                                                                                                                                |
| Report filter sizes        | 50 space keys, 50 account ids, 10 surfac | Per report query.                                                                                                                                                                                       |
| Overview chart buckets     | 500 time buckets maximum                 | Per overview time series.                                                                                                                                                                               |
| Macro date range           | 1 to 365 days (picker offers 7, 30, 90)  | Default 30 days.                                                                                                                                                                                        |
| Reports page date range    | 7 / 30 / 90 day presets plus a custom ra | Default 30 days.                                                                                                                                                                                        |
| Historical lookback        | 400 days                                 | The health check that drives the reports notice bar looks back 400 days, matching GA4's default retention ceiling.                                                                                      |
| Settings propagation delay | Up to about 10 minutes                   | Four caches sit between saving a setting and a reader's browser acting on it: a 60-second server cache, the published projection, a 10-minute CDN cache and a 10-minute cache in each reader's browser. |
| GA4 data latency           | Up to 48 hours                           | New events and newly created custom dimensions take up to 48 hours to appear in Google Analytics. This is Google's behaviour, not the app's.                                                            |
| Space-level settings       | None exist                               | There is exactly one settings page for the whole site. The space page is a report view only.                                                                                                            |
| Google connection scope    | One per Confluence site                  | The Google connection is site-level, not per-user. One admin connects and everyone uses it.                                                                                                             |

## A few things worth knowing

* A limit that is reached is reported in the interface, not in a log you have to find.
* Limits are per site or per tenant depending on the limit. The table says which.
* Edition can change some of these.
