To quickly set the height & width, select the cell(s) and navigate to Home tab, under Cells group, open Format options. Click AutoFit Row, it will set automatically set row height to minimum, and same with the case for clicking AutoFit Column Width.
Now width & height of selected column(s) and row(s) is set to minimum.
