how do you increase in-game text size?

I cannot seem to see an option that allows me to increase the in-game text size when talking to NPC.

I have tried all the options available. I even tried to lower the game resolution but the test size did not change.

My vision is rather poor and my glasses make little difference. I have to sit very close to the screen to read the text.

Windows 7 Home Premium
Core i5 4670k
ASUS R9 270X DCII
ASUS Z87-Pro Motherboard
16 GB Ram
100 GB SSD (OS and FF14ARR installation)
2x120 GB HDD (Raid 0)
1TB HDD

There isn't a way in-game to change NPC text size.

I solve the problem by turning on Windows Magnifier when reading NPC text. The game's Screen Mode has to be set to Borderless Windowed for Magnifier to work (System Configuration -> Display Settings).

Press Windows logo key + Plus Sign (+) to turn Magnifier on and Windows logo key + Minus Sign (-) to turn it off. A magnifying glass will appear that you can click on to open the Magnifier dialogue box. From there you can set the percent magnfication you prefer and whether the whole screen or only a small portion of it will be magnified. I've found that 150% magnification in Full screen works best for me.

The magnfied text is a little grainy but still very readable.
