Microsoft Excel includes Page Layout options to help you resize the height for the footer. You can adjust the Custom Margins option to raise or lower the worksheet’s bottom margin, which increases the amount of free space at the bottom to make more room for a taller footer. Resizing the footer can help you fit more content, such as an image, in the footer box, and prevent overlapping the content on your worksheet.

Step 1

Click the "Insert" tab on the command ribbon, and then click "Header & Footer" in the Text group. Click anywhere in the worksheet, and then scroll down to bring the footer section into view.

Step 2

Click the "Click to add footer" section to bring up the left, middle and right footer boxes, select a footer box, and then enter your footer text. The Header & Footer Tools ribbon and the Design tab display on the ribbon.

Step 3

Click anywhere on the worksheet, click the "Page Layout" tab on the ribbon, and then click "Margins" in the Page Setup group to open the menu.

Step 4

Select "Custom Margins" to open the Margins tab sheet in the Page Setup window. The Footer and Bottom list boxes with arrow buttons display near the page sample.

Step 5

Click an arrow button or type a new value in the Footer or Bottom boxes to adjust. For example, type "4" in the Bottom list box, and then click "OK" to raise the lower margin and allow more space above the footer. To make the footer box shorter and placed higher up the page layout, type a larger value in the Footer list box, and then click "OK." To make the footer box taller -- and placed lower down the page layout -- enter a smaller value in the Footer list box, and then click "OK."

Step 6

Press "Ctrl-S" to save your updated worksheet.
