Convertible MeasrementRecently, we published our Rear-facing Convertible Space Comparison blog, but it wasn’t an all-inclusive list and the primary focus was on how much room different convertible seats take up when installed in the rear-facing position. As part of that review, we listed the rear-facing seated height measurements and stated height limits of various convertibles. In the breakdown section for each seat, we included additional information such as RF weight limits and FF height & weight limits.

Now, we’re expanding that database and making an all-inclusive list, specifically of rear-facing convertible measurements, height and weight limits. We have data on almost every convertible seat currently in production. I have measured each seat personally because measuring is a bit subjective but I have done my best to be consistent in the way I measure each seat. Even then, measuring isn’t an exact science since the contours of these seats aren’t in a straight line. But again, I have done my best to be consistent in my measuring techniques.

Here are the results:
