12x18 vs 14x18 Poly Bags
12x18 and 14x18 are close in size, so the right pick comes down to what you ship. The 14x18 gives about 36 sq in more usable face (252 vs 216 sq in), so it suits thicker or bundled items; the 12x18 ships the same item for less postage when it fits. Packrift stocks both: 6 and 6 SKUs are live below.
