Amazon Courier Bag Sizes

For Easy Ship and self-ship orders you pack the parcel yourself, so the bag size is your choice. Use a tamper-proof courier bag that closes over the product without strain. MarkRTD stocks Amazon polybags in 6×8 and 12×16 inch, and plain courier bags in more sizes.

Enter your packed product’s length, width and height above to get the bag size you need and the bags that fit.

Fit Matters for Weight Charges

Amazon’s weight handling fee uses the higher of actual and volumetric weight. A parcel in a bag much bigger than the product can be charged for more weight, so pick the smallest bag that fits.
