Hello. The "Big" sizes are just an extension of the "Regular" sizes, whereas the "Tall" sizes are about 3 inches longer.
For example, sizes will run Small, Medium, Large, X-Large, XX-Large, 3XL, 4XL, 5XL. The "Regular" sizes are Small through XX-Large and the "Big" sizes are 3XL through 5XL.
The Tall 3XL will fit the same as a Big 3XL through the torso except it will be 3 inches longer.
