Trade Suppliers of Pricing in Proportion Packaging
Royal Mail large letter and small parcel size boxes for businesses
In 2013, the Royal Mail changed its pricing structure and introduced a requirement for what are now known as PIP Boxes (standing for “pricing in proportion”).
Whilst this may sound simple – effectively creating a box that will fit within certain dimensional restrictions – in practice there are still a wide number of varying designs, sizes and options. These should all be considered before deciding on which PIP Packaging to use (or even if it is right for your company).
As such, GWP Packaging will design and manufacture bespoke PIP boxes for your business. This ensures that not only do you get a perfectly sized carton (that can also reduce your costs), but that it provides the perfect level of protection during transit as well.
Please see below for the PIP boxes that can be purchased – and fully customised – through GWP Packaging.

PIP boxes can be designed and manufactured in a number of ways, including tuck in flaps (a FEFCO 0427 style) or 5 panel wraps. Each option allows for the boxes to be supplied flat – saving on storage – and are easily assembled as well.
All PIP packaging can be enhanced with printed logos and branding, either on the outer surfaces for promoting your brand during transit, or on the inside panels to allow for a unique “unboxing experience” (and being more discrete during delivery).

What does PIP stand for?
PIP stands for “pricing in proportion”. This relates to the defined sizes as set out by Royal Mail in 2013, which determine the maximum sizes / weights letters and parcels can be to benefit from specific pricing bands. These are split into what have become known as small letter, large letter, small parcel, medium parcel and, finally, large parcel.
What material is typically used for PIP boxes?
In order to maximise the available space within the box or packaging, and to minimise weight, a single flute corrugated (cardboard) material is typically used. However, the specific grade (E flute / B flute / etc.) will depend on how heavy the item within is, and what levels of protection are required. GWP will be able to advise the most suitable material for your specific application.
What is the maximum size of large letter box?
The maximum dimensions of a large letter box are 353 x 250 x 25mm (length x width x depth). There is also a maximum weight of 750g (0.75Kg). It is obviously possible to reduce any of these dimensions to ensure a good fit with your specific product or item being shipped however.
What is the maximum size of small parcel box?
The overall size that a small parcel box must not exceed is 450 x 350 x 160mm (length x width x depth). The maximum weight limit as set by the Royal Mail for this category is 2Kg. The dimensions of these boxes can be altered within these limits to avoid the unnecessary use of void fill (such as foam pellets).
What is the maximum size of a medium parcel box?
Medium parcel boxes can be up to 610 x 460 x 460mm (length x width x depth), and can hold weights of up to 20Kg. Due to the weight of the products that could potentially be shipped in this category, it may be the case that double walled cardboard material is sometimes used.
What happens for boxes larger than medium parcel?
For any boxes that exceed any of the 610, 460 or 460 mm (length x width x depth) dimensions, this will be categorised as a large parcel. Please note however that there is a weight limit in this category of 30Kg. If you are frequently shipping larger / heavier parcels than this, you may find using a courier with bespoke sized boxes (tailored to your items) would be more cost effective.
Should I use PIP boxes if my business doesn’t ship using Royal Mail?
If you are not using Royal Mail delivery services, then you may find that tailoring your packaging boxes to the sizes of your products (rather than Royal Mails arbitrary sizes) will prove more cost effective. This is because many couriers will use volumetric pricing, whereby you will be charged for shipping any wasted space within the boxes too. Custom sized boxes can also help you minimise the amount of void fill and cushioning material required.
Should I use stock or bespoke sizes?
If you are a start-up or only process very low volumes of orders, stock sized products (such as those found from merchants and online shops) will likely be more cost effective. However, if your business sends mid – high volumes of parcels / orders, then using bespoke packaging could reduce your costs significantly.
Can PIP boxes be customised?
As GWP Packaging will design and manufacture all PIP boxes to your specific requirements, it is possible to customise them in a number of ways. This includes material type (i.e. white or kraft finish) and wide range of one, two or full colour printing types.
