When creating a new table in Word, all of the columns in your table are initially the same size. However, when entering data, you will quickly discover that some columns need to be wider than others in order to accommodate the data.
You can adjust column width by clicking and dragging the column border or the column margins to the desired length or, for a more precise measurement, use the Width box on the Cell Size group of the contextual Layout Ribbon.

To Adjust Column Width
To adjust column width by dragging the column border:
- Move your mouse pointer over the right border of the column you wish to adjust until the pointer transforms into two vertical lines with a horizontal double arrow through it
- Click and drag to the right or left until border is the desired width
To adjust column width by dragging column margins:
- Click the border margin box on the ruler and drag until column is the desired width
To adjust column width by using the Width box:
- Click anywhere in the column that you want to adjust.
- Click the contextual Layout tab under Table Tools.
- Click in the Width box and type in the desired width for the column.
- Press Enter.
