Klenke's 17th-century atlas, from which the images of the Tartars and Muscovites were taken (look, don't get confused!) is worth looking at not only in scanned form, but also in real size. The page format is 1.75 by 1.9m.
In Pereslavl-Zalessky there is a copy of the Gospel of enormous size. From the photo, I think the size of such books is clear. For people of our stature (and we are told that over the past centuries the population has increased in stature considerably, due to nutrition and comfortable conditions for life), such weight is prohibitive even for weight-lifters, for a gift version they are not worthy, and for their carrying or use special mechanisms are needed. Dozens of similar editions have survived, where even the font is excessive for a person of normal height.
