+# Vector sizing calculator
+
+The `{vector-sizing-calculator}` directive embeds an interactive calculator for estimating disk and off-heap memory for `dense_vector` fields. The docs site loads the React/EUI web component that registers the `<vector-sizing-calculator>` custom element.
+
+## Usage
+
+```markdown
+:::{vector-sizing-calculator}
+:::
+```
+
+No body content or options are required. Configuration happens in the widget UI.
+
+## Live preview
+
+:::{vector-sizing-calculator}
+:::
+
+## Requirements
+
+This directive only produces useful output where the assembled documentation site includes the vector sizing bundle (see `src/Elastic.Documentation.Site/Assets/web-components/VectorSizingCalculator/`).
