The Fit to Contents option in the Arrange menu is used to display an object at its original size. For example, if an Image object contains a graphic set to Scale to fit, the Fit to Contents option will return the object and its bounding box to the size of the original graphic.
You will often find it neater if the bounding box containing an object is the same size as the object, and you will need it to be if you want to add a border to the object using the Border tab in the object’s Properties dialog box.
Click on the object (or objects) to select them. A bounding box will surround each object.
On the Arrange menu, click on the Fit to Contents option. Each object will be reset to its original size.
