Change the width of cell borders

Microsoft Excel applies a default thin line style when you add an outer cell border or gridlines.

To change the width of a cell border, follow these steps:

  1. Select one or more cells that have a border that you want to change.

  2. Right-click over the cells you've chosen and select Format Cells and, in the popup window, click the Border tab.

  3. For a continuous line, choose one of the thicker styles from the Line box.

  4. In the Presets section, click your existing border type.

  5. Check your new border width in the preview diagram. If it's not the way you want it to appear, click another Line style.

  6. Click OK.
