Fill global scale?

Fill global scale? [Why 3'-3 3/8"???]

[context: I'm in US using imperial dimensions]

Is there a global setting that establishes the base size of any given fill?

When I use the Fill tool, I find I need to constantly select the Custom Distortion option in order to scale a variety of fill patterns.

And, when I first click on the fill to start that adjustment process, the dimension of both x & y are set to 3'-3 3/8", which is an exceptionally weird number. I guess it's anchored to 1 meter, despite the US units of the template.

Can this starting scale for the fill be modified? Where do I find that setting?

[Or, are we limited to modifying Fills by their individual scales in the Fills dialog?]

Thanks!
