You ca add a line that’s drawn all the way around the letters in your text by adding a stroke blending option. To do so, go ahead and double-click on the text layer that you want to add the stroke to. And I'm going to move my layer style dialog box underneath my text so I can see the changes being made. Go ahead and click on stroke and you can see it automatically goes ahead and adds a stroke around my letters. Better go ahead and click on Color and then I'm going to change the color first of all. And I want something that blends in a little bit better. So I’ll do a little bit darker shade of red and you can change the size of the stroke, you can increase it to make it really big, you can make some really neat fonts this way. Actually, keep it fairly big, I like that.

You could choose to have it outside, you can choose to have it inside, you could choose to have it coming from the center, like it outside or you could do a blend mode, you could do normal, you could do something in softer. You could do a mix, you could do penlight, whatever you think goes best with your font. You can lighten it up to change the total look of it and this gives you a big range of options right here, I like it dark. And then Fill Type, you can also choose to fill it with a gradient or to fill it with a pattern. I really like that dark red, I'm going to go ahead and leave that.

So that’s how you add a stroke to your text in Photoshop.
