You can use the FlexLayout module to listen to media changes and set the number of columns based on the screen size. Then you bind the <code>cols</code> value to the number of columns variable. <a href="https://stackblitz.com/edit/angular-jfjeow?embed=1&amp;file=app/grid-list-flexible-example.ts" rel="nofollow noreferrer">Here is a Stackblitz example</a>.

HTML:

<pre><code>&lt;mat-grid-list [cols]="columns" rowHeight="2:1"&gt;
 &lt;mat-grid-tile&gt;hello world&lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;hello world&lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;hello world&lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;hello world&lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;hello world&lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;hello world&lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;hello world&lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;hello world&lt;/mat-grid-tile&gt;
&lt;/mat-grid-list&gt;
</code></pre>

TS:

<pre><code>import { Component, OnDestroy } from '@angular/core';
import { MediaChange, ObservableMedia } from '@angular/flex-layout';
import { Subscription } from 'rxjs';

/**
 * @title Flexible grid-list
 */
@Component({
 selector: 'grid-list-flexible-example',
 styleUrls: ['grid-list-flexible-example.css'],
 templateUrl: 'grid-list-flexible-example.html',
})
export class GridListFlexibleExample implements OnDestroy {
 watcher: Subscription;
 columns: number = 4;

 constructor(media: ObservableMedia) {
 this.watcher = media.subscribe((change: MediaChange) =&gt; {
 if (change) {
 if (change.mqAlias == 'xs') {
 this.columns = 2;
 } else if (change.mqAlias == 'sm') {
 this.columns = 3;
 } else {
 this.columns = 4;
 }
 }
 });
 }

 ngOnDestroy() {
 this.watcher.unsubscribe();
 }

}
</code></pre>

I'm trying to display 8 small grids in a page. Each grid has 2 columns and 
 4 rows, with about 2 words per cell.

<pre><code>&lt;mat-grid-list cols="2"&gt;
 &lt;mat-grid-tile&gt;
 hello world
 &lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;
 hello world
 &lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;
 hello world
 &lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;
 hello world
 &lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;
 hello world
 &lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;
 hello world
 &lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;
 hello world
 &lt;/mat-grid-tile&gt;
 &lt;mat-grid-tile&gt;
 hello world
 &lt;/mat-grid-tile&gt;
 &lt;/mat-grid-list&gt;
</code></pre>

I am opened to other suggestions on how to arrange them in a pleasing style, but what I was thinking was:

<ul>
<li>if there is enough space to fit 4 in one line, display them on 2 lines: 4+4</li>
<li>else if there is enough space to fit 3 in one line, display them on 3 lines: 3+3+2</li>
<li>else if there is enough space to fit 2 in one line, display them on 4 lines: 2+2+2+2</li>
<li>else display them on 8 lines</li>
</ul>

I don't really know how to do that, what would be the correct approach for this setup and conditionals ?

I can't even manage to display 2 grids on one line, it seems that by default a grid takes all the page width available.
