by the measures of the universe?

Question

The way we apprehend all material objects other than ourselves is affected by their size relative to us. They range from stars millions of times the size of our earth to the constituents of sub-atomic particles. Our perspective on them differs from that of other sentient creatures, even though those creatures may have a lot in common with us, and by the measures of the universe may be similar in size to us

Ultimate questions, Bryan Magee

What does the author mean by saying "by the measures of the universe"?

Answer 1

He means that in the grander scheme of things, considering how massive so many things in the universe are, other animals are relatively the same physical size as us.

Hope this helps!
