You are at the display settings menu on the top bar you will see a tab that reads appearance, click on this tab. Once you are at the appearance tab click the advanced button (it should be in the lower right corner) once you are at the advanced window, you will see a scroll down menu that has desktop displayed, click on this and scroll down to icons, now simply raise the font of the icon size and the icons will become larger, to raise the font of the text there is a bar underneath that, it will list the format the text is displayed in, to the right of that will be the size, you can also bold the text with the bold button on the right side of this bar.
