You can align multiple objects relative to one another, or specify an object’s location using its x and y coordinates.
Select an object, then click the Arrange tab at the top of the sidebar on the right.
If you don’t see a sidebar, or the sidebar doesn’t have an Arrange tab, click 
in the toolbar.
Enter x and y values in the Position fields.
The x value is measured from the sheet’s left edge to the object’s upper-left corner.
The y value is measured from the sheet’s top edge to the object’s upper-left corner.
When you drag an object, its x and y coordinates are displayed.
Tip: You can open the Arrange controls in a separate window that you can move anywhere. Choose View > Show Arrange Tools (from the View menu at the top of your screen, not from the View menu in the toolbar).
Select an object, then do any of the following:
Move an object one point: Press an arrow key.
Move an object ten points: Hold down the Shift key while you press an arrow key.
You can align objects so they line up along a vertical or horizontal axis.
Select an object, or Shift-click to select multiple objects.

If you don’t see a sidebar, or the sidebar doesn’t have an Arrange tab, click in the toolbar.

If two or more objects are selected, the objects align to the object most in the direction you selected. For instance, if you align three objects on the left, the object that is most left doesn’t move, and the other object aligns to it.
Tip: You can open the Arrange controls in a separate window that you can move anywhere. Choose View > Show Arrange Tools (from the View menu at the top of your screen).
