GitHub user dosubot[bot] added a comment to the discussion: Checking Dashboard Size
<!-- Answer --> There isn’t a single built-in feature in Superset that shows dashboard “size,” but you can measure it in a few ways depending on what you mean: - If you want to know the storage size (how much layout/config data is stored), Superset uses a field called `position_json` to store the dashboard layout. The character length of this field is what matters for the internal limit (default is 65,535 characters, configurable via `SUPERSET_DASHBOARD_POSITION_DATA_LIMIT`). If you hit this limit, you’ll see a “dashboard too large” error. You can check the length of `position_json` in the database or via the API if you need to estimate this metric [discussion](https://github.com/apache/superset/discussions/36250). - If you want to know the complexity (number of charts, datasets, or tabs), you can use the API endpoints: `/api/v1/dashboard/<id_or_slug>/charts`, `/datasets`, and `/tabs` to get counts of each component [API reference](https://github.com/apache/superset/blob/master/superset/dashboards/api.py). - If you want a proxy for the dashboard’s export size, you can export the dashboard as a YAML file using the `/export/` endpoint and check the file size of the exported YAML [API reference](https://github.com/apache/superset/blob/master/superset/dashboards/api.py). - If you mean the rendered size (width/height in pixels), there are frontend methods like `getScrollSize()` that return the dashboard’s scrollable area, but this is only about the UI, not storage or complexity [source](https://github.com/apache/superset/blob/master/superset-frontend/src/embedded/api.tsx). Let me know which metric you’re most interested in and I can help with more specific steps. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
