A family of Microsoft word processing software products for creating web, email, and print documents.
If the text that you want to modify is also formatted in a particular language (via the Language dialog box), you can search for text in that language and choose to replace it with that same content in a different point size.
In the Find & Replace dialog box (Ctrl+H), use the Format control to specify language and point size (and any other formatting that you want to change). In the example below, ^& represents the found text. Selected formatting is indicated by the text next to "Format" (for "Find what" and "Replace with," respectively).
