How to change product per row count in Magento 2

[sanekjn]

Hello All! How to change product per row count in Magento 2? I'm using custom magento theme and create a vertical category navigation menu. But products shows only 2 per row. Any help would be appreciated!

The standard Luma design theme automatically adjusts the number of products in a row  to a browser window's size: https://mage2.pro/t/895

If your custom theme behaves oddly then I recommend ask its developer for support.

Thanks for answer! I had templatemonster theme and when I switch to Luma all works great - there are 4 products per row. Please advise what files need to be customized!
