Grid Options

See how aspects of the Bootstrap grid system work across multiple devices with a handy table.

Extra small devices Phones (<768px) Small devices Tablets (≥768px) Medium devices Desktops (≥992px) Large devices Desktops (≥1200px)
Grid behavior Horizontal at all times Collapsed to start, horizontal above breakpoints
Max container width None (auto) 750px 970px 1170px
Class prefix .col-xs- .col-sm- .col-md- .col-lg-
# of columns 12
Max column width Auto 60px 78px 95px
Gutter width 30px (15px on each side of a column)
Nestable Yes
Offsets Yes
Column ordering Yes

Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, applying any .col-md- class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg- class is not present.
