It's difficult to pack small cubicles and have them still really count as cubicles. Looking for some random pictures from Google Images, my office looks kind of like this: https://s3.amazonaws.com/mentoring.redesign/s3fs-public/open...

And here is a random picture of a small cubicle design: https://cubiclebydesign.com/wp-content/uploads/2017/10/Works...

Note the dividers in the center area extend back to the sides of the chairs, even though the chairs are not pushed in. If you tried to do that in the first image, you would block the walkway. (You certainly couldn't do the design of the farther-away cubicles; they take up much more room per employee.)

You could do something like this: https://www.quill.com/content/index/resource-center/office-f... But I'd probably call that an open office layout, honestly.
