I don't know if this is the right place to ask for help, but I know there are alot of smart people in this forum when it comes to making inserts and covers and I'm really not knowledgeable doing this. I purchased a live soundboard recording of the Greatful Dead from dead.net, but you have to download the inserts for the individual concerts. This is the place to download the insert https://www.munckmusic.com/wms/dead/index.html After choosing the Alpine Valley Music Theater for my insert, it brings up Adobe Acrobat ( I'm using an HP 2175 printer). Since this concert was a 3- cd set I bought a couple of 3- cd set jewel cases to try to make this as nice as possible.

Adobe Acrobat is set to print the covers to fit a standard jewel case, about 4 3/4" wide by 4 11/16 high", but 3- cd set jewel cases need an insert that measures approximately 4 3/4" wide by 5 3/8" to 5 7/16" high. Can someone give me a step by step way to size these inserts to the size I need? Any help is really appreciated.
