What is it called when you want to automatically create columns that are the same length in a newsletter?

Answers

Its called column creation

The process of automatically creating columns that are the same length in a newsletter is often referred to as text balancing or column balancing. In desktop publishing software, this feature helps ensure that each column ends at the same point on the page, providing a clean, professional appearance to the layout.
