How to change column count in listing page Magento2? -

i want make product listing page use 3 columns instead of 4 default columns.

i've got categories on magento2 web, , products on each category. want them show 3 columns count, shows 4 default columns count, how can change plz me this.

magento 2 don't have option set column count magento 1.

to change 4 3 (for theme based on luma) need change css , reset image size.

css code need change inside magento_catalog module, file:

_listings.less 

and this:

    .media-width(@extremum, @break) when (@extremum = 'min') , (@break = @screen__l) {   .products-grid .product-item { width: 100%/5 }   .page-layout-1column .products-grid .product-item { width: 100%/6 }   .page-layout-3columns .products-grid .product-item { width: 100%/4 }   .page-products .products-grid .product-items { margin: 0; }   .page-products .products-grid .product-item {     width: 24.439%;     margin-left: calc(~"(100% - 4 * 32.439%) / 3");     padding: 0;     &:nth-child(3n+1) {       margin-left: 0;     }   }   .page-products.page-layout-1column .products-grid .product-item { width: 100%/5 }   .page-products.page-layout-3columns .products-grid .product-item { width: 100%/4 } } 

to have 3 columns, change (i recommend add code _theme.less):

    .media-width(@extremum, @break) when (@extremum = 'min') , (@break = @screen__l) {   .products-grid .product-item { width: 100%/4 }   .page-layout-1column .products-grid .product-item { width: 100%/5 }   .page-layout-3columns .products-grid .product-item { width: 100%/3 }   .page-products .products-grid .product-items { margin: 0; }   .page-products .products-grid .product-item {     width: 32.439%;     margin-left: calc(~"(100% - 3 * 32.439%) / 2");     padding: 0;     &:nth-child(3n+1) {       margin-left: 0;     }   }   .page-products.page-layout-1column .products-grid .product-item { width: 100%/4 }   .page-products.page-layout-3columns .products-grid .product-item { width: 100%/3 } } 

after in

/your_theme/etc/view.xml

change small image width , height. 240 , 300, change 300 , 330.

refresh , it.
