There does not seem to be a place to describe the physical dimensions of an artwork in metadata. However, there is a field titled: Iptc4xmpExt:AOPhysicalDescription. I manually added it by opening a jpg in a text file and it was read by ExifTool. When I tried to write to the same field, "Warning: Tag 'AOPhysicalDescription' does not exist" was the result.

Code Select
exiftool -X -xmp-Iptc4xmpEx:AOPhysicalDescription="string of text" /Users/[username]/Pictures/2.jpg

Am I missing something? Thank you in advance.

ExifTool will read anything you wrote in XMP, even if it isn't writable.  I suspect your XMP was formatted incorrectly, otherwise you should have been able to use the same tag to write with ExifTool as you got when reading.  The tag name is "ArtworkPhysicalDescription".  See the XMP iptcExt tags documentation for a complete list.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

If I simply wanted to create the field via ExifTool, is that possible or does ExifTool have to append an existing tag?

Of course ExifTool is able to create the tag if it doesn't exist.

exiftool -ArtworkPhysicalDescription="something" FILE
