16"x14"x3" Royal Mail Postal Box
In this section you will find size 16x14x3" (440x349x79mm) die-cut pizza style single wall boxes, in various quantities/pack sizes. These have been specifically manufactured to meet the maximum external size allowed by Royal Mail under their 'small parcel' guidelines, enforced on 1 April 2013. Perfect for fitting anything that can be sent as a small parcel, providing an all round box for all these items, ensuring that you keep postage costs down.
These top quality and presentable boxes are manufactured in 0427 style format (die-cut). They are stronger and more durable than standard single wall boxes. The dimensions once assembled are as follows:
Internal Dimensions - 419x338x72mm External Dimensions - 440x349x79mm
Royal Mail made changes to the way that parcels are treated within their network for individuals or businesses that send less than 1000 parcels a year. They used to have two maximum parcel sizes for items qualifying as 'small parcels', both of which we stock and are available on this site. They have now merged these sizes to create a new 'overall' size, as of October 2014. We stock the new maximum size as well, which is also available on this site. The cost of sending 'small parcels' in their network is significantly cheaper than sending 'standard parcels'.
The new stipulations as of 20 October 2014 for maximum sizes of 'small parcels' are the following (note these are external dimensions):
Maximum Length - 450mm Maximum Width - 350mm Maximum Depth - 160mm
The previous stipulations were as follows:
Maximum Length - 450mm Maximum Width - 350mm Maximum Depth - 80mm
Maximum Length - 350mm Maximum Width - 250mm Maximum Depth - 160mm
