Thank you Jacob, I understand the concept but if I am not starting with a prime number I will always end up with an uneven calculation. That is why I would like to be able to change by fixed numbers rather than percentage. I just find it interesting that Illustrator does not allow The calculation method to me changed. For example, Photoshop provides almost the same option in Image Size. The difference is that a dropdown selection is provided that allows eight choices for accuracy. Percentage is the default such as Illustrator. But to avoid the problem I am having, Photoshop offers Pixels, Inches, Centimeters, Millimeters, Points, and Picas. I do appreciate your trying to help.
