Microsoft Excel 2010 lets you control the size of a worksheet's cells. By default, the cells appear in uniform size. Resize one cell or multiple cells to fit all your data. For example, adjust the borders to allow more data to display in a wider cell. You can also apply an "Alignment" command so that the text wraps into a taller cell when there are multiple lines.

Step 2
Move your cursor over the separator line between two headers — for example, the vertical line between column headers "B" and "C." The pointer changes to a small, black, vertical line with two opposing arrows. If this symbol does not appear, click the header and then hover the cursor over the separator line.
Step 3
Click and drag the boundary line left or right to resize the column or row. Release the mouse button.
