You can change the default row height for the worksheet you are currently working in.
You can override the default row height by sizing the row. For more information, see Sizing rows.
Row height does not automatically change to accommodate a font size larger than the default row height or the height assigned to a particular row. As long as all text in a row is the same as, or smaller than the assigned row height, the text can fit in the row. If you make any text in the row taller than the default row height or taller than the height assigned to that particular row, the row height does not expand to accommodate the font. You must adjust the row height.You can size rows from 0 (zero) to a maximum of 240 points in height.
