You can have swatch sizes for lines and regions auto resize with font size changes. When setting the font size for labels in the Legend Frame Properties dialog box, you can select to auto increase sample (swatch) size to match the font size setting.
To auto increase the sample size to match the font size:
- Double-click on the legend, or right-click on it and select Modify Legend Frame Properties from the pop-up menu.
- In the Legend Frame Properties dialog box, click Aa button in the Labels pane and set a new font size for labels.
- Select the Auto Increase Sample Size to Match Font check box.
- Click OK.
The Legend Designer window refreshes and the sample swatches resize to match the font size of the labels. This setting, on an individual legend frame, overrides the Legend Designer window preference set by selecting on the PRO tab, in the Options group, click Legend Window.
