Sketch/Adobe XD to Storyline Font Size too Big

I'm creating designs in the software called Sketch. I'm sending the designs over to a developer who will be using Storyline. I created a title slide in Sketch. The font size is 80, but when I looked at this font size (80) in Storyline, it's way too big. I've read that it may have something to do with the PPI, but I'm not sure. Regardless, what's the solution? I tried Adobe XD, and had the exact same problem.
