As for the rest of the tribes:
from the east side to the west side, Benjamin, one portion. Bible

“Benjamin, one portion.” Nothing is said about the width of each tribal area except it seems that they are equal. Also, since the scholars are somewhat divided on the exact north and south boundaries of the Land, it is hard to exactly divide them. The result of that is that we are not sure how wide from north to south each tribal area is. (See commentary on Ezek. 48:1).
