Mobile Fighter G Gundam
In-universe, the shortening of mobile suits was explained as a way to combat the ever-growing costs of producing larger and larger mobile suits. In the same way, the model kits would also decrease in terms of manufacturing cost. In reality, however, as 1/144 scale model kits were becoming the norm instead of 1/100, the cost to develop new technology to color smaller kits and to create smaller, more articulated joints, among other things, actually drove the production cost up. However, this in-universe explanation met with dissatisfaction by fans of the franchise, especially model kit fans, so after retaining the smaller size through "Mobile Suit Victory Gundam", starting with "Mobile Fighter G Gundam" the mobile suits were gradually increased in size once again. By the release of "Turn-A Gundam" and "G-Saviour", the titular mobile suits stood at 20 and 18 meters, respectively.
