Royal Mail parcel & mailing guide

Size & weight guide for UK letters and parcels

There are few things more irritating than realising that you have put the wrong postage onto a parcel or underestimated the costs because you chose a letter rather than large letter. Helping to make this headache a thing of the past, we have created a simple Royal Mail parcel and mailing guide which gives you the 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 that you need and also the postage costs that you should allocate when sending mail from your offices. Need Royal Mail postage stamps?
