Do softer shouldered jackets, sportcoats, etc. fit larger than coats with more structured shoulders?

For example, would a coat measuring 17.75 fit with soft shoulders fit larger than a structured coat with the exact same measurement?

Can this even be generalized? I hope this makes sense....

Thanks
