AWeber's Drag & Drop Email Builder is designed to give you as much control over the message you're creating as possible. In addition to the many styling options we provide that enable you to manipulate your text, you're able to adjust the line-height of your text elements.
After clicking on any text-based element within your message, you'll see a black styling menu appear sitting right on top of the selected element. In that menu will be an option to adjust the line-height for the whole element you've selected.
You'll have the option to choose between a line-height of 1, 1.15, 1.5, and 2. The Default option will adjust the line height based on the template that is in use.
The below image is an example of the default line-height in a message.
This next image serves as an example of the same paragraph element with double line-height in effect.
