How do you single space in a Office 2007 Word document?
To change Line Spacing in Word 2007:
Use the Line Spacing on the Home tab of the Ribbon in the Paragraph Group of Word to select the amount of spacing you require within the document.
Select your desired line spacing. By default in Word 2007 the line spacing is set to 1.15. From this menu you can select to have your line spacing set to 1, 1.15, 1.5, 2, 2.5 or 3. If you want a more granular line spacing (say 1.63, 1.05 or maybe 12pt or 23pt or anything like that), you can click on the Line Spacing Options item in the Line Spacing Menu.
