Breakpoints
API that enables the use of breakpoints in a wide variety of contexts.
For optimal user experience, material design interfaces need to be able to adapt their layout at various breakpoints. Material-UI uses a simplified implementation of the original specification.
The breakpoints are used internally in various components to make them responsive, but you can also take advantage of them for controlling the layout of your application through the Grid component.
Default breakpoints
Each breakpoint (a key) matches with a fixed screen width (a value):
- xs, extra-small: 0px
- sm, small: 600px
- md, medium: 960px
- lg, large: 1280px
- xl, extra-large: 1920px
These values can be customized.
CSS Media Queries
CSS media queries are the idiomatic approach to make your UI responsive. The theme provides four styles helpers to do so:
- theme.breakpoints.up(key)
- theme.breakpoints.down(key)
- theme.breakpoints.only(key)
- theme.breakpoints.between(start, end)
In the following demo, we change the background color (red, blue & green) based on the screen width.
const styles = (theme) => ({
root: {
padding: theme.spacing(1),
[theme.breakpoints.down('md')]: {
backgroundColor: theme.palette.secondary.main,
},
[theme.breakpoints.up('md')]: {
backgroundColor: theme.palette.primary.main,
},
[theme.breakpoints.up('lg')]: {
backgroundColor: green[500],
},
},
});
down(sm): red
up(md): blue
up(lg): green
<Root>
<Typography>{'down(sm): red'}</Typography>
<Typography>{'up(md): blue'}</Typography>
<Typography>{'up(lg): green'}</Typography>
</Root>
JavaScript Media Queries
Sometimes, using CSS isn't enough. You might want to change the React rendering tree based on the breakpoint value, in JavaScript.

Custom breakpoints
You define your project's breakpoints in the theme.breakpoints
section of your theme.
theme.breakpoints.values
: Default to the above values. The keys are your screen names, and the values are the min-width where that breakpoint should start.theme.breakpoints.unit
: Default topx
. The unit used for the breakpoint's values.theme.breakpoints.step
: Default to 5 (0.05px
). The increment used to implement exclusive breakpoints.
If you change the default breakpoints's values, you need to provide them all:
const theme = createTheme({
breakpoints: {
values: {
xs: 0,
sm: 600,
md: 960,
lg: 1280,
xl: 1920,
},
},
});
Feel free to have as few or as many breakpoints as you want, naming them in whatever way you'd prefer for your project.
const theme = createTheme({
breakpoints: {
values: {
mobile: 0,
tablet: 640,
laptop: 1024,
desktop: 1280,
},
},
});
If you are using TypeScript, you would also need to use module augmentation for the theme to accept the above values.
declare module '@material-ui/core/styles' {
interface BreakpointOverrides {
xs: false; // removes the `xs` breakpoint
sm: false;
md: false;
lg: false;
xl: false;
mobile: true; // adds the `mobile` breakpoint
tablet: true;
laptop: true;
desktop: true;
}
}
API
theme.breakpoints.up(key) => media query
Arguments
key
(string | number): A breakpoint key (xs
,sm
, etc.) or a screen width number in px.
Returns
media query
: A media query string ready to be used with most styling solutions, which matches screen widths greater than the screen size given by the breakpoint key (inclusive).
Examples
const styles = (theme) => ({
root: {
backgroundColor: 'blue',
// Match [md, ∞)
// [960px, ∞)
[theme.breakpoints.up('md')]: {
backgroundColor: 'red',
},
},
});
theme.breakpoints.down(key) => media query
Arguments
key
(string | number): A breakpoint key (xs
,sm
, etc.) or a screen width number in px.
Returns
media query
: A media query string ready to be used with most styling solutions, which matches screen widths less than the screen size given by the breakpoint key (exclusive).
Examples
const styles = (theme) => ({
root: {
backgroundColor: 'blue',
// Match [0, md)
// [0, 960px)
[theme.breakpoints.down('md')]: {
backgroundColor: 'red',
},
},
});
theme.breakpoints.only(key) => media query
Arguments
key
(string): A breakpoint key (xs
,sm
, etc.).
Returns
media query
: A media query string ready to be used with most styling solutions, which matches screen widths starting from the screen size given by the breakpoint key (inclusive) and stopping at the screen size given by the next breakpoint key (exclusive).
Examples
const styles = (theme) => ({
root: {
backgroundColor: 'blue',
// Match [md, md + 1)
// [md, lg)
// [960px, 1280px)
[theme.breakpoints.only('md')]: {
backgroundColor: 'red',
},
},
});
theme.breakpoints.between(start, end) => media query
Arguments
start
(string): A breakpoint key (xs
,sm
, etc.) or a screen width number in px.end
(string): A breakpoint key (xs
,sm
, etc.) or a screen width number in px.
Returns
media query
: A media query string ready to be used with most styling solutions, which matches screen widths greater than the screen size given by the breakpoint key in the first argument (inclusive) and less than the screen size given by the breakpoint key in the second argument (exclusive).
Examples
const styles = (theme) => ({
root: {
backgroundColor: 'blue',
// Match [sm, md)
// [600px, 960px)
[theme.breakpoints.between('sm', 'md')]: {
backgroundColor: 'red',
},
},
});
Default values
You can explore the default values of the breakpoints using the theme explorer or by opening the dev tools console on this page (window.theme.breakpoints
).
