Royal Mail have changed the small parcel size limits to include a combination of the previous wide and deep small parcel sizes.
The changes will come into effect on 20th October 2014 and run through to 18th January 2015.
The new Small Parcel size limit will be 450mm x 350mm x 160mm. Not only this but it will now cost less to send.
1-2 kg parcels will now cost the same as 0-1kg parcels if using your franking machine. This will mean that a 1-2kg parcel sent via your franking machine Second Class will now be £3.50 instead of £4.50
Thank you again Royal Mail.
