There are few things more frustrating than realising that you have put the wrong postage onto a parcel. It can lead to costly delays and wasteful to and fro. To help you make this headache a thing of the past, we have created a simple Royal Mail parcel and mailing guide which gives you the official measurements of letters, large letters, small, medium and large parcels.
Simply look down the list and find the size and weight that is right for your requirements. You can then make more informed decisions about the stationery you will need and the postage costs you should assume when sending mail from your offices.
