Change how text wraps
Control how text wraps in the TextEdit windows and in printed documents, and choose if words are hyphenated.
Change how text wraps in the window
You can wrap text to the window or to page margins based on paper size.
Choose Format > Wrap to Window to wrap text in the TextEdit window.
Choose Format > Wrap to Page to wrap text within page margins.
To change the paper size, choose File > Page Setup.
Change how text wraps in a printed document
You can print a document with line breaks that match those in the TextEdit window.
Choose File > Print, then deselect “Rewrap contents to fit page.”
If you don’t see the option, click Show Details, then choose TextEdit from the print options menu.
You can have TextEdit automatically hyphenate long words at the ends of lines, which can make the right margin appear smoother.
Choose Format > Allow Hyphenation.
To turn off hyphenation, choose Format > Do not Allow Hyphenation.
