To accommodate your data, you can change the size of your columns and rows! If you go to the Home tab, hit Format (in the Cells group), and then click Row Height to adjust the rows and Column Width to adjust the columns. You can then enter the exact measurement! You can also use your mouse to adjust cells by clicking and dragging the divider line to expand. Also, if you double-click the divider between two rows or columns Excel will resize the row to fit the contents.
