Change Font Size to 7 or Below in a Tableau Workbook

By following these steps, you can change the font size to 7 or below in a workbook via Tableau Desktop, to ensure that the data label are displayed correctly, even in a space-constrained dashboard. 

Note:
• Some fonts cannot be set to a size below 8.
• In this example, using the default font in Tableau products, Tableau Book, allows you to set the font size below 8.

Steps:
1. Open the Workbook:
   • Launch Tableau Desktop and open the workbook where you need to adjust the font size.

2. Navigate to the Sheet:
   • In the dashboard, click on the sheet where you need to change the font size.
   • Click on the "Go to Sheet" button to navigate to the specific sheet (e.g., "Sheet 1").

3. Access Font Settings:
   • From the menu bar, select "Format" and then click on "Font".

4. Select the Field:
   • In the "Format Font" pane, go to the "Field" dropdown and select the field you want to adjust (e.g., "Text 1").

5. (Option) Change the Font:
   • Select the font you want to use from the list of available fonts. In this example, select "Tableau Book".

6. Adjust the Font Size:
   • In the "Format: [Field]" pane, under "Header", manually enter "7" in the font size box (since size 7 may not be available in the dropdown).
   • Press the Enter key to apply the change.

7. Verify the Changes:
   • Click on a blank area to ensure the changes are applied.
   • Reopen the "Format: [Field]" pane to confirm that the font and size settings are retained.

8. Save the Workbook:
   • Save the workbook to ensure all changes are preserved.

9. Publish the Workbook:
   • Publish the updated workbook to Tableau Cloud or Tableau Server and verify that the font size adjustments are reflected correctly.
