got it

but then I should have typed the same, because I think we wrote simultaneously

Empress
thanks for the clarification
apart from the variation due to manufacture and warrior strength/size (after all, there were no shield factories allthough I read they were made by specialists)
I know 4 different sizes (A. Mcbride: The Zulu War. Osprey MaA 57, 1976, referenced by literature and photographs)
1 the large Shaka time shields-shoulder to ankle (also used by veteran warriors, see above): isiHlangu
2 the standard 1879 shields- shoulder to shin, which is pretty large as well, since still used in the traditional fighting technique: umBhumbuluzo
3 dancing and everyday shields (used in the Zulu uprisings)- arm length: iHawu
4 Dress shield- wrist to elbow : amaGqoka
now it seems you refer to the modeler having the choice between isiHlangu and umBhumbuluzo
by my eye measurment, the shields photographed with the models are hardly war shields
(read also my previous post)
which I would also state given my experience with actual shield hand to hand combat
anyway, these are wargaming miniatures and not museum miniature replicas
but in this case my argument would have been:
"we made the smaller shields this size in order to make them distinctive from the bigger ones"
your models are very nice, finely detailed and well proportioned and I like them
