Pricing in Proportion

You can save on postage costs by following the Royal Mail’s Pricing in Proportion system (PiP) and using our PiP boxes, postal cartons and other packaging. The 3 classes of mail are Letter, Large Letter as well as Small and Medium Parcels.

As of Monday 20th October 2014, the Royal Mail have introduced a new, more convenient, larger Small Parcel
size, so now, you can send more, and pay less!

They have done away with the previous two sizes (originally identified as Wide & Deep Small Parcels) and combined the two sizes together, so we get the best of both worlds.  Royal Mail have even brought in a special promotion: You can now send a Small Parcel for the low price of just £2.80 for up to 2kg.

Take a look at our even wider range of packaging below that falls within the new Small Parcel sizing
and save money sending out your products.

Our PiP Boxes

We have a range of PiP boxes, padded envelopes and postal cartons that are ideal to use as Pricing in Proportion packaging. They are all supplied flat-packed for convenient use and easy storage.

There are 6 sizes of our padded envelopes and 7 of our bubble lined envelopes that fit in the Large Letter category, as well as one white postal carton while the larger sizes go into the Small Parcel class. For other Small Parcel postal solutions we have white postal boxes (4 sizes), foam-lined postage boxes (3 sizes) and 10 sizes of our convenient standard single wall cardboard box including our L96 single wall postal carton which is to Royal Mail's maximum small parcel size.

Our PiP boxes and packaging for the Medium Parcel category includes our bubble-lined or padded envelopes, our book mailing boxes and of course a choice of differently sized single wall cardboard boxes and strong double wall boxes.

Our wide range of cardboard boxes is perfect for posting bulkier items in the Medium Parcel category while conforming to the Royal Mail Pricing in proportion boxes specifications.

Tips for using the PiP system

For instance, you could save money on a direct mail marketing shot by posting it in a postal product conforming to the Large Letter requirement – one of our padded envelopes – rather than the Small Parcel. It is also cheaper to post an A4 document by folding it into an A5 rather than A4 size envelope (Letter as opposed to Large Letter).

Why Royal Mail have changed to PiP

Before the introduction of the PiP system, Royal Mail realised there were often discrepancies in the cost of mailing goods. It was thought that the amount of postage paid – based on weight – did not necessarily reflect the cost of handling and sorting items such as large letters and different sizes of postal carton. Postage was low on light, large items but high on heavy, smaller ones.
