+## Change the console width
+
+To change the console width for the execution of a code block, use the `width` option.
+Internally, Markdown Exec will set the `COLUMNS` environment variable accordingly,
+and restore its previous value after execution.
+
+If the executed code doesn't support this environment variable,
+the default console width will be used (it could be the current width or some arbitrary value).
+
+````md exec="1" source="tabbed-left"
+```bash exec="1" width="10"
+echo $COLUMNS
+```
+
+```bash exec="1" width="1000"
+echo $COLUMNS
+```
+````
+
 ## Change the working directory
 
 To change the working directory for the execution of a code block, use the `workdir` option.
