Calvin Harris -- Taylor Swift is Not My Type AT ALL

This is stunning ... Calvin Harris went way beyond saying he was not into Taylor Swift ... he said she's the OPPOSITE of his type.  

Calvin went on "Capital Breakfast," a British radio show, in November and was asked about Tinder and the celebs who would earn a right swipe.   

You gotta hear him ... he's not putting us on. Calvin says Taylor earns a solid left. 

So what happened between November and March? Taylor looks the same, but somehow in the wee hours he changed his tune and his swipe.
