As per the data collected and tabulated for the 11 different versions of iPad, the Flagship of Apple iPad, it looks as if there is continuous improvement and/or at least change in the physical dimension (Length x Width x Height) measured in millimeter & inches, while the weight of the 11 versions of iPad is also available in (Grams & Ounces).

As the data is displayed graphically as well (see below the Table), the dimensions of the different versions of iPad are continuously decreasing, from iPad Wi-Fi, the initial offer, to the iPad mini.
Similarly, there is continuous decrease in the weight of the iPads, starting from the iPad to Ipad Mini.
The change in the weight is also expressed in the line graph:
