Adjusting Grid Size

All the sudden my grid size using Windows 10 app has gotten too small to read. How do I restore grid size?

Hold CTL key and roll mouse wheel?

Or Control and then - or +

Or click your browser settings then click + or - in “Zoom”.

Or Ctrl 0 to return to default zoom level

It is your browser “zoom” controls, Use Zoom In from the menu or appropriate shortcut.
