What Size of Mailing Boxes will fit into Australia Post Prepaid Satchels? - Awesome Pack’s Mailing Box Dimensions Guide
Auspost Prepaid Satchels is a common way to mail your goods for a small business but sometimes you want to put your product in a cardboard box before you slide it in the satchel for protection & presentation. This Mailing Box Size Guide will help you answer common questions relating to what size mailing boxes will fit into certain Australia Post Satchels or any other plain satchel of a certain size.
In order to understand what size Cardboard Box will fit into a certain satchel size you firstly need to understand the following concept:
Boxes are 3 Dimensional with Length x Width x Height whereas Satchel sizes are 2 Dimensional with only Length x Width.
So when considering what size courier bag/satchel to buy for your cardboard box you need to understand that the length, width and height will all need to be considered. Please don’t fall into the trap of buying a satchel size that has a length and width similar to a mailing box and thinking it will fit. This way of thinking omit the consideration of height of the box and therefore will often not fit.
As a general rule, in order for a mailing box to fit inside a mailing satchel, the satchel length and width need to be substantially bigger than the length and width of the mailing box. How much bigger? Well that depends on the height of the box.
The table below will give you an approximation of what mailing box will fit into the Australia Post prepaid Satchel:
