We’ve created this example in Illustrator, but Photoshop and InDesign can be used to create letterhead designs too. Microsoft Word is pretty low-tech compared to Illustrator or InDesign however, that’s what your clients are using and your letterhead design is useless to them if they can’t edit and add content to it, so knowing how to create a Microsoft Word letterhead template is key. At the end of a letterhead design project, it’s pretty common to hear your client say: “I want this as an editable letterhead template in Microsoft Word.” They usually don’t own or know how to use advanced graphics-editing programs like Adobe Illustrator, InDesign or Photoshop, and it simply doesn’t make sense for them to purchase those expensive programs.
