Do you really mean the "status" bar, or do you perhaps mean the "scroll" bar
that contains the sheet tabs?
No to the first,
Yes to the second.
To increase size of sheet tabs:
Right click in Windows Desktop,
<Properties> <Appearance> tab, <Advanced> button,
Expand "Item" box, and choose "Scrollbar",
Then increase the "size" number to whatever,
Then <OK>, <OK>.
