Media Query Tester & Responsive Design Helper

Welcome to Breakpoint Buddy, a fast and easy Media Query Tester that helps you test responsive breakpoints and CSS media queries right in your browser.

This script tests a series of media queries on your device using matchMedia(), then prints the results in a table. It's a handy way to see which media queries and values match on a device, and since it tests a variety of values for each query on the device, it can show the minimum and maximum values for the query that match, e.g. the exact values that match for (min-width: ...). For ranges printed in the Matched Values column, both values are inclusive.

Note: Media queries are tested every second. If you resize the window or change the zoom level, the media queries will be recalculated.

One of the media features tested is @media (scripting: none). If this matches, then JavaScript is disabled and the table can't be populated, so you'll never see that particular match in the table.
