I did not like the look of the font size change implemented earlier so I switch the size back to its default. I am aware this presents a problem for some of my readers. Hopefully the following suggestions will be helpful to you.
PC USERS – Microsoft Internet Explorer, Chrome, Firefox
Keyboard shortcut – Hold down the <CTRL> key and tap the “+” or “–” key to increase or decrease font size as required. <CTRL> + 0 should restore text to the default size.
Alternate Method – Click View on the browser Menu Bar , then select Text Size (NOTE: May be ZOOM in Firefox)
MAC OS X USERS – Using Safari or Firefox
Keyboard shortcut : Hold down <command> or <Apple> key, tap the “+” or “-” key to increase or decrease font size as required. <command> or <Apple>+ 0 restores text to the default size.
Alternate Method – Click View on the browser Menu Bar , then select Zoom In, Zoom Out or Zoom Text Only.

Hi Jerry……… I think leaving the font size selection to the user is the right choice as everyone has different likes and dislikes. The minute you enlarge the font because of a request from one reader, another will complain it is too large – so what do you do? Using the CTRL + keys is the best way I think.
You can also hold the ctl key and roll the wheel on your mouse.
Well, I see that being late reading blogs, you have solved the problem the easy way!
