As you can see, the shield on the Viking spearman is big. This unit is ment to form the bulk of the viking Sjoldborg/Shieldwall. The landsmann on the other hand, who is an offencive shock unit, has a smaller shield to be more agile.
The vikings used pretty large shields. I have seen some of them in museums, and most of them were 80-90cm wide. (some eaven bigger)
If you compare the size of the spearman's shield to hes body, it's about half hes hight. The average hight of a western man is about 180cm, so that makes the diametre of the shield about 90 cm.
EDIT: Oh, you wrote "on the archer", it's the same size as that of the birk. spear, and smaller then most of the ithers, it's just that the archer on the pic is posed a bit crumbled (see legs) making the shield look relative bigger..
Cheers!
