Every Coolife Amazon listing checked states a single Item Dimensions L x W x H figure with no separate body only measurement. Across the three hardside pieces (20, 24 and 28 inch) the largest of the three stated numbers runs 1 to 2 inches above the size named in the product title, which points to that figure being the overall exterior including wheels and handle housing rather than the bare shell, though Coolife never says so explicitly. A few listings also enter length, width and height in an order that does not match the case's real upright orientation, so the three numbers are best read as the case's overall footprint rather than a reliable height versus width breakdown.
