I've noticed a difference in font sizes between my local Sketch file and the Sketch filew once it's been uploaded (through Craft) to an Invision project. I am including a screenshot comparing the two. The top mockup is through Invision and the bottom mockup is my Sketch file. You can see that the font size in Sketch (bottom example) looks larger than the font shown through Invision (top example). Any idea why this happens?
