When it was decided to show the Enterprise-C in the TNG episode "Yesterday's Enterprise", a studio model had to be built. Andrew Proberts original design (which silhouette was used on the "Ship Wall" in the Enterprise-D's conference room), was deemed to have too complicated shapes to be build as a physical model within the budget limitations. So the design was simplified a little. This first studio model was solely used to depict the Enterprise-C in this episode. For the later appearances of Ambassador Class ships (USS Zuhkov, USS Excalibur and USS Yamaguchi), a second model was used. The two miniatures were not exactly identical. They show a lot of significant differences. There is a good article about these Ambassador Variants at ex-astris-scientia.org. In this article, there is a picture of the second model with the nacelle pylons shortened and the nacelles moved down this way. This was most probably done due to damages the model suffered from exhibition at different locations after its use as an actual filming model. Therefore, this version is non-canon as it was never seen on screen this way. However, i like the look of it. To me the ship does look more balanced this way, and it now doesn't violate Gene Roddenberry's rule that nacelles must be fully visible from the front. With the original configuration, they were partly covered by the saucer. Although, the canon Yamaguchi was not shown this way, i named this variant after it, because the model in the pictures with the shortened pylons is still labelled USS Yamaguchi.
There are two somewhat official size figures out there. 526m and 478.5m, you can read about this at memory-alpha. Eaglemoss seems to try to offer a compromise, stating 520m in the magazine that comes with the miniature. Personally i like the 526m figure, as it is more close to the 524.256m of Andrew Probert's original design, and it fits perfectly to the relative sizes of the parts taken from the Ambassador and Galaxy Class to create the Niagara Class.
