Increase size of 'You might also like' on product page

I am struggling to find the location of where I can change the size of this title 

'You might also like' on the product page. Can someone either point me in the right location or is there some magical code that I can use to increase it etc.

@niteshifte You can add this code snippet within the Custom CSS panel: 

.ProductItem .ProductItem-related-label {
    font-size: 1.8rem !important;
}

You can customize the font size by adjusting the '1.8rem' value in the code to fit your preferred size.

Thanks a mill Sam!
