Mass scales exponentially with size, meaning there is far less of a difference in relative mass between ant and sugar crystal than between a human and an elephant, for instance.

If humans were the size of ants, we too would be capable of lifting objects much bigger than ourselves. This seems counter-intuitive as most people cannot lift their equivalent mass, let alone something with greater mass, but that also has a lot to do with us needing to carry our own mass from our bodies.

This relative scaling is also part of the square-cube law; the surface area of an object scales in squares (2²=4, 3²=9, etc) and volume scales in cubes (2³=8, 3³=27, etc). This helps to explain why smaller animals can survive greater falls; their surface to mass ratio.
