A little while back my wife and I visited Van's to go on one of their very expensive "free" demo rides in the RV-14. When I got home I noticed that we happened to take almost the exact same picture in both the RV-7 and the RV-14. These two pictures give a pretty good perspective of the difference in size between the two planes. Look at the rollbar over my wife's head in each picture for a sense of perspective.
The other thing that is less commented on, but very noticeable in these pictures, is how far down the canopy extends on the side of the fuselage on each plane. Notice how the fuselage on the RV-7 is near shoulder height, while the RV-14 is closer to elbow height. Being shorter, my wife really noticed this difference more than the headroom when the canopies were closed on each plane.
