Which layout is using a particular map?

DARRYLBEER — Mon, 12 Jan 2026 02:37:48 GMT

In projects that have many maps, and many layouts that may have more than one map frame (e.g. main and inset), is there an easier way to find which layout is referencing a particular map without having to open and check every single layout? Or is this something I should post in the suggestions section?

Thanks,

Not sure if this is possible for you or not, but maybe spread your work across multiple aprx files instead of using 1 aprx. This is just a suggestion as it might not meet your business needs.

Thanks for the suggestion, I've just moved to using map series to reduce the number of maps and layouts in the aprx. My question came from trying to delete a map I thought wasn't being used but Pro telling me it was. I found it after looking through the remaining few layouts.

Hi @DARRYLBEER

We have updated the message you get when deleting maps.

Unfortunately, this improved message is not available with 3.3. It was introduced with version 3.6. Until you are able to upgrade to 3.6 or newer you should be able to use the python script that @BarryNorthey linked to get the information you want. Thanks Barry!

Hope this helps,

Tom
