Hi @SanavaH., thank you for providing that information! After taking a look on my end, I was able to use the “Fit to Page” function in Document Settings and that seemed to help with the size.
However, I noticed that some of your Org Chart columns are far a part from each other. So I would recommend moving some columns closer together where possible, as this will allow you to continue to increase the size of your font from 13pt.
One other note, it looks like you have text in your shapes, but then additional text boxes above your shape to use two different font sizes. This can make it harder to scale your objects all together to continue to increase the size. I would recommend putting all of your text in a single shape, and setting the size to Auto, as you adjust your chart to be the proper size. Then you can adjust each line of text by highlighting it within the shape, if you would like to make certain pieces of information smaller.
Please let me know if you have any further questions!
