die-size physical vs official

So, someone on reddit asking for a one-in-one-pic comparison of Fiji, Polaris 10 and Vega 10.

 

At the same time, people was wondering why the measured size does not agree with the official size.

 

The secret is the inner die-size, which you can not measure with a calliper. If you know the outer dimensions of the entire die, you can calculate the dpi and crop out the inner die and automatically get the correct dimensions for the inner die-size.

 

The inner die-size of Polaris 10 and Vega 10 is very close to the original die-size. Fiji's official die-size must be the physical/outer die-size.
