Inner Carton Dimensions

Our carton sizes are the outside of the box, so you would subtract the thickness of the paper to get the inner dimensions. 18pt paperboard is 0.018 inches. 

Example: On a 2.0" x 3.0" x 6.0" box, the inner dimensions would be: 

(2-0.018) x (3 - 0.018) x (6 - 0.018) = 1.982" x 2.982" x 5.982"
