Leading is the amount of vertical space between two lines of text.
In the Design Center, you can change the amount of leading.
Click on the text you would like to adjust. Once you have the textbox selected, click on the Leading icon on the toolbar at the top, which is located right in between the Alignment button and the Color dropdown (see below). From there, you can drag your cursor left or right. Dragging left will decrease the space in between the text, while dragging right will increase the space between the text.
If you have any difficulties adjusting the leading, or if things just don’t look right on your design, please do not hesitate to contact us for help.
