Board measures only 7 X 12 inches. Each army is about one-quarter inch square, with Roman numerals of I, III, V and X. Dice are about one-half inch to a side. Cards measure 1 and 1/8 X 1 and 3/4 inches. Board and army pieces are magnetic, so you can play a game while traveling. It all folds down into a 7 X 4 X 5/8 inch wallet that actually fits into a hip pocket.
