Scaling with an object's bounding box


    When you drag a handle on an object's bounding box, the object scales relative to the opposite handle, or you can change the reference point to the object's center. You can also lock the proportions of an object as you scale it.

    If the object has a stroked path or a size-related effect, the stroke and effect will scale with the object if the Scale Strokes & Effects preference is selected. (See Setting scaling preferences.)

To scale an object with the object's bounding box:

  1. Select the object.
  2. Drag a bounding box handle until the object is the desired size. Do any of the following to control the scaling behavior:
    • To maintain the object's proportions, hold down Shift as you drag.
    • To scale relative to the object's center point, hold down Alt (Windows) or Option (Mac OS) as you drag.
