Earlier today, Japanese blog Mac Otakara pointed to a blog post [Google translation] from repair firm iLab Factory showing what is claimed to be a design schematic for a next-generation iPhone front panel part. The schematic appears to correspond closely with part photos that leaked yesterday, showing a taller display and a shift in the position of the FaceTime camera to above the device's earpiece.
But while iLab Factory's version of the schematic has had many of the details blurred out, another source has provided MacRumors with a complete version of the schematic including measurements for several of the important features on the panel. The schematic appears to have been originally posted by Cydia Blog.

The schematic does not show an exact total height for the part in question, but calculations based on pixel counts and the known height of the display mask area suggest that the overall height of the part is roughly 122 mm, approximately 7 mm taller than the overall height of the iPhone 4S. With yesterday's leaked photos suggesting that the design will see a similar treatment to the iPhone 4/4S with metal edges of the device extending out further than the front panel, the overall device height and width on the next-generation iPhone would measure slightly larger than seen on this part.
