Finer control over image width in Note (Markdown Editor)?

This useful guide spells out how to adjust image size in Note.

The thing is, I am looking for an image size that is greater than the default and less than the full screen size (width=“full”).

Changing the size in pixels (width=“2000”) and as a percentage (width=“150%”) only seems to change the resulting size up to the note area width.

How can I have a bit more control over the output image size on a widescreen display? Thanks for reading.
