The alignment you choose for a paragraph results in a distinctive appearance, and you can experiment with the various alignments to achieve just the right look for the way you’ll be using that particular paragraph. With Word, you can adjust the alignment of an individual paragraph, several paragraphs, or even all your paragraphs.
Click in a paragraph, or select all the paragraphs whose alignment you want to set.
On the Home tab, click any of the following:
The Align Left button to align the paragraph with the left margin or left indent, creating a ragged right edge
The Center button to center each line of the paragraph, creating both a ragged left edge and a ragged right edge
The Align Right button to align the paragraph with the right margin or right indent, creating a ragged left edge
The Justify button to align the paragraph with both the left margin or left indent and the right margin or right indent by adding any necessary space between words
