Take a look at the thread entitled, "Home Screen Problem," which asked exactly the same question.
Just FYI, you can change the icon size and text size independently of each other (but icon text will scale based upon what you're doing to the icon size when you change icon size). The icon size can be increased by holding down Ctrl and pushing the mouse scroll wheel up (this can be imitated with the mouse pad by Ctrl plus whatever gesture is scroll up, but I have a lot more trouble with getting this to do exactly what I want it to do using a mouse pad).
Here are the steps to enlarge icon text:
Note: Steps 1 through 3 can be skipped and you'll end up directly at step 4 if you elect to open Control Panel instead and choose the Display settings there.
1. Right click on the desktop and choose "Display Settings" on the context menu
2. The Display Settings dialog will appear:
You should choose the "Advanced Display Link" at the very bottom of the dialog.
3. The Advanced Display Settings Dialog will appear:
You should choose the "Advanced sizing of text and other items" link near the bottom of the dialog.
4. A Windows 10 variant on the good old-fashioned Control Panel->Display settings dialog will appear:
You'll see that I pulled up "Icons" from the dropdown menu then increased the size of the font to 11 and made it bold as well, then hit the "Apply" button.
Here are two screen captures of the "after" effect of doing the above:
Save As dialog with enlarged and bolded icon text:
Desktop with enlarged Icons and enlarged & bolded Icon Text:
Hope this helps.
