Default Sizes for Twitter Bootstrap’s Media Queries

Introduction

I love Twitter’s Bootstrap. I find that when developing with it, either Bootstrap 2 (2.3.2) or Bootstrap 3, that I always need to apply custom styles at the different sizes. Especially when going beyond Bootstrap’s standard functionality. After all, it’s just a front-end framework.

Below you’ll find nicely formatted Media Queries for starting with either of the Bootstrap versions. You can use this as a starting point for your projects. It’s basically what I use when creating a new website or webapp. I’ve also provided links to Github for quick access.

Bootstrap 3 Media Query Breakpoints

Bootstrap 3 is a mobile-first front-end framework. I’ve included the correct order for the Media Queries below, but I’ve also included at the bottom of them the non-mobile first breakpoints in case some people aren’t used to the mobile-first methodology since technically both will work.

Min-Width: Refers to everything greater than or equal to the amount given. Max-Width: Refers to everything less than or equal to the amount given.

    /*==================================================
    =            Bootstrap 3 Media Queries             =
    ==================================================*/

        /*==========  Mobile First Method  ==========*/

        /* Custom, iPhone Retina */
        @media only screen and (min-width : 320px) {

        }

        /* Extra Small Devices, Phones */
        @media only screen and (min-width : 480px) {

        }

        /* Small Devices, Tablets */
        @media only screen and (min-width : 768px) {

        }

        /* Medium Devices, Desktops */
        @media only screen and (min-width : 992px) {

        }

        /* Large Devices, Wide Screens */
        @media only screen and (min-width : 1200px) {

        }

        /*==========  Non-Mobile First Method  ==========*/

        /* Large Devices, Wide Screens */
        @media only screen and (max-width : 1200px) {

        }

        /* Medium Devices, Desktops */
        @media only screen and (max-width : 992px) {

        }

        /* Small Devices, Tablets */
        @media only screen and (max-width : 768px) {

        }

        /* Extra Small Devices, Phones */
        @media only screen and (max-width : 480px) {

        }

        /* Custom, iPhone Retina */
        @media only screen and (max-width : 320px) {

        }

Bootstrap 2.3.2 Media Query Breakpoints

    /*=====================================================
    =            Bootstrap 2.3.2 Media Queries            =
    =====================================================*/
    @media only screen and (max-width : 1200px) {

    }

    @media only screen and (max-width : 979px) {

    }

    @media only screen and (max-width : 767px) {

    }

    @media only screen and (max-width : 480px) {

    }

    @media only screen and (max-width : 320px) {

    }
