Pillow Shipping & DIM Calculator The pillow’s actual size never changes — it remains 24 × 18 × 6 inches. What changes is the shipping package size. Without compression: Box dimensions = 24 × 18 × 6 DIM weight is calculated on this size. With compression/vacuum packaging: Box dimensions = 18 × 12 × 4 DIM weight drops significantly. Once delivered, the pillow expands back to its normal size. Key Point: Product size = constant. Package size = adjustable. Compressible vs Non‑Compressible Products Compressible items: Pillows, blankets, clothes, cushions, soft toys, mattresses. → DIM weight can be reduced with vacuum/compression packaging. Non‑compressible items: TVs, monitors, furniture, glass items, hard equipment. → Dimensions cannot be reduced meaningfully
