Admitting right off the bat the limitations of measuring things on screens, and that this is purely for whiling away time until real numbers are known:
BUT, the newest videos out of CA do give us what I believe is a *collective* first:
California license plates are 12” wide by 6” tall. This provides a known measure.
Given the distortion of perspective in images, one can achieve any reliable level of accuracy in relevant size only comparing objects that are ~identical distances from the camera. Because the license plate is on the same plane as the CT tailgate, the known dimensions of the license plate can be a reliable comparison to the features of the CT tailgate on that same plane of distance from camera. (Conversely, one could not with any accuracy measure, e.g., rear view mirrors because they are materially further from the camera).
I used the PowerPoint ruler function, with the image blown up, to provide a scale of 24 PP ruler marks across the license plate. So, each hash represented ~ 1/2”. I double-checked with Microsoft PowerTools pixel measurement. I’d guess the measurements are within 1.5” of true.
Resulting tailgate area measurements were as follows:
Given the limits of perspective, the above are the *most* available measurements with any reasonable degree of accuracy using the license as the standard.
The resolution of the photo wasn’t great, so edges were a bit fuzzy. A higher resolution photo would have been nice.
Still, a not bad extraction of scale

- a regulation CA license plate
- on the ‘pre-production beta’
- with a square-on photo of the rear end

Resulting tailgate area measurements were as follows:
- (Red) bottom SS edge of tailgate: 71.5”
- (Yellow) topmost edge of tailgate: 72.5”
- R/L taillights: <5”
- (Blue) Distance between R/L taillights: 62.5”
- (Orange) top ‘shelf’ of sail pillar @ tailgate: 7”
- (Purple) tonneau at tailgate (and so distance between sail pillars at tailgate): 57”
