Welcome to the Samsung Members Community Canada. As mentioned by balou, & uzairm87, you need to open a message conversation and by Sliding two fingers on the display Pinch In to decrease/reduce the font Size and Pinch Out to increase the font size.
OR
Please follow the below steps to change the font size. Open Device Settings >> Select the Display and wallpaper option >> Select Font >> Next to Font Size you will see a slider - you can slide it to the left or right, making all visible fonts smaller or bigger >> Tap the name of any font from the list to change your text style >> You can always tap Default to change back to your phone's default font >> Tap Done to save your settings.
Thank you all very much gentlemen. The pinch on the messages worked great. It amazes me that something as simple as that can be nowhere in a search or in the manual. I have it in my noggin now though. 🙂
