The default height of an Excel row is 15 points, but you can adjust each individual row from 0 to 409 points.
Position the mouse pointer below the row you want to adjust. The mouse pointer becomes a crosshair.
Press and hold the mouse button and drag the row line down to increase the row height or up to decrease it.
Release the mouse button. The row height will be changed.
Tip
Adjust Rows Automatically To automatically adjust row height to exactly fit the contents of the cell, double-click the mouse after the pointer becomes a crosshair.
