In Excel 2010, you can change any column widths or row heights in your worksheets to improve the readability and appearance of data. For example, if your worksheet contains many numbers, you can widen the columns to make the worksheet less cluttered. You should always widen columns that contain cells with truncated text entries or numbers that Excel shows as ######.
Based on the default 11-point Calibri font, the default column width is 8.43 and the default row height is 15. If you change the default font type or size, Excel may also change the standard column width or row height. You can manually set a default column width by choosing Format→Default Width in the Cells group on the Home tab. You cannot manually set a default row height.
