While all frameworks/grid systems do roughly the same thing, if you want to try something different you can try Susy(susy.oddbird.net)

Susy has got a lot of praise for being very flexible and configurable. While in other systems you usually have your predefined grid classes that you assign to the html, in Susy you write your grid stuff inside the css using the mixins.

Check out Grid.css (demo). It's a simple, responsive, mobile first and without dependencies 16-columns grid system made with Sass

Foundation's Grid system is pretty dope foundation.zurb.com/sites/docs/flex-grid.html

Skeleton is a nice little framework if you want some extras with the grid

there are several unofficial SASS implementations, here's one: github.com/whatsnewsaes/Skeleton-Sass
