Royal Mail Parcel Sizes

Royal Mail

When shipping multiple items, miscalculation of parcel sizing can end up costing you a lot of money. It’s really important to ensure you have the right PIP (pricing in proportion) box for the parcel you’re sending. The Royal Mail use a series of weight and size restrictions to calculate the postage costs.


We want to make it easier for businesses to select the correct parcel size. Once you know the size you require, browse our Ecommerce Packaging range, to find the perfect fit for your product.

Additional parcel options


Postal Tube is ideal for sending maps, posters or artwork in the post. If you can roll it, you can post it in a Postal Tube! Our 23 x 3″ Postal Tubes are manufactured from strong brown Kraft paper outer, and are supplied with polythene end caps. Please remember to allow 15mm at either end for the end caps. The caps fit snugly, but tape can be applied to add extra security.


For posting, the length of the item plus twice the diameter must be less than 104cm, with the greatest dimension less than 90cm.
