I went with size medium and these fit perfectly. Initially, I was worries about the waist size given I am waist size 29~ so naturally I should go with small as I wear small in everything else.
But given I am 6 feet tall, the original advice was to go with the length of the pants instead of waist size. This couldn't be more right, as I think a small size would have come up short with the extended cuffs. You can tighten the waist size quite a bit and it sits at my hip instead of waist.
I am having issues attaching pics with my phone so I can upload some pics later if anyone wants for reference.
Hope that helps.
