AFAIK there is no such setting available. Default Row height is directly
determined by default font size and Column width is indirectly determined by
default font size by way of "number of characters".

You might be able to dictate the grid dimensions through VBA, but what kind
orf meaningful content could a worksheet have if cells were that small?
