With the text selected you can add a stroke in a couple different places, the text tools at the top or from the swatches panel, you can adjust the weight in the stroke panel. Circled below are the fill and stroke colors
Do not outline any font in InDesign, only for graphic purpose, like filling a letter with an image, otherwise avoid outlining text.
I am planning on making a cover for my book and plan the title on the cover to be in a red font with an outline. The document will be converted to a PDF for final printing.
I assume you are referring to a stroke? Outlining in graphic design terms generally means converting live text into a vector, enabling it to be used in all sorts of ways and to avoid font issues, but equally creating the issue that it won't be editable. If you want to add a simple stroke, hit F10 or Window>Stroke to bring up the options. Highlight the desired text and add the required stroke, you will have basic colour/thickness options as well as type of outline (dotted/double etc) and some positioning options which may achieve what you want. I often have a duplicate of the text behind the original with the stroke on. Have a play.
That is why I said I may not be using the correct term.
Yep. To those who said use Illustrator or Acrobat Pro, I don't have those.
If you want to add a stroke to the letters just do it on live text.
If you want to add some fancy design to the lines, do it on live text in Illustrator, save it as .ai file and import it into InDesign.
I sometimes outline a font when using a non-OpenType face for large headings that might cause our print house problems. I'm interested in your response about not outlining fonts in InDesign, and I'd love to know why this isn't a good idea.
With Outlining font in InDesign you get following problems:
Instead of outlining in InDesign, you can do it in Acrobat Pro, there is a command, which does not cause any problems for the printer nor for the designer.
Just to completely clarify here:
In InDesign and most other Adobe apps, "outlining" text means converting it from font glyphs to complex vector shapes that are no longer editable "letters." This is a debated practice; it used to be common for certain kinds of print preparation and some printers (usually ones using antiquated processes) will still ask for it. It's also done with a few letters or words when the designer wants to modify or blend the letterforms, as is often done in Illustrator. But for many reasons, it's something to avoid in InDesign unless you have well-understood and well-thought-out reasons for doing so.
I think what you mean is simply putting an outline around letters. Easy-peasy in most Adobe apps; just select an outline color and thickness. You can then tweak how the line lays on the letter shape (outside, inside, on the center of the outline itself).
But wait, there's more! If what you want is to make the text stand out from a complex background, you can use a variety of effects that are more subtle than a hard line. Put your title in a text frame, select the frame, and explor the Object | Effects options, especially the bevels, glows and shadows. You can get a very distinctive look that isn't at all "fancy" looking but is more elegant than just a colored outline.
Hope that helps, or at least brings the other comments into focus.
