Spacers aren't small enough

First-time Squarespace user here. I am using Spacers to adjust where picture and text boxes are located. In many cases I cannot get these spacers to small enough. The smallest width is actually quite large (not sure how many pixels, but appears approx .75 inches on the screen). Is there any way in Settings (or elsewhere) to adjust the smallest size a Spacer can be??

Thanks!

No. this is not possible. Only with CSS but this will bring you different problems. The Squarespace grid has 12 columns.
Keep the mobile version in mind - then the spacer will appear on top of the next image on the right...

Thanks so much. Frustrating, but at least now I understand. So – basically the smallest width of a spacer is 1 column width... correct?

Yes if it is vertically used. 

But if you have a gallery block or a summery - and within this blocks a grid design you can adjust the distances very detailed.

I tried this - i  created a summary grid with no content and reduced the width to the minimum (50).  It ends up exactly the same size as the minimum width of a spacer.
