This largely depends on the dimensions and style of your box.
Our default board (material) stock for each style is as follows:
| Box Style | Flute/Caliper | Thickness | Weight Rating* |
| Shipping Boxes | B-Flute | ⅛ inch (0.125") | 30 lb |
| Mailers (small/medium)** | E-Flute | 1⁄16 inch (0.0625") | 10 lb |
| Mailers (large) | B-Flute | ⅛ inch (0.125") | 20-30 lb |
| Product Boxes | 16pt or 18pt | N/A | 16oz or 1 lb |
* Maximum weight will depend on arrangement of contents inside of box, strength of tape/glue used to assemble your box, and average shipping & handling conditions.
** Small/medium Mailer boxes can be requested in B-Flute if preferred. Additional charges may apply for this thicker material option.
Because we offer custom-sized boxes, we're unable to provide a list of per-box weights for all sizes. But here’s a handy chart with some of our most common sizes and their estimated empty per-box weights as a point of reference!
