Royal Mail postage costs: a confusion-busting guide

Since April 2013, any parcel or package sent in the UK has to be measured and weighed before postage costs are calculated. Previously, items were classified on the basis of weight alone, but Royal Mail introduced a new set of prices that they believed were more in line with the actual cost of handling and delivering items, taking into account the fact that some larger, lighter items need to be delivered by van.

The changes led to some initial confusion amongst consumers used to the old posting measures, whilst subsequent changes merely muddied the waters further. In October 2013, Royal Mail introduced a second small parcel size to allow people to post either wide, shallow parcels (max 45cm x 35cm x 8cm) or narrow, deep parcels (max 35cm x 25cm x 16cm) as a small parcel.

Thankfully, these two 'small' sizes were replaced by a single small parcel, which combines the larger dimensions of the previous versions (max 45cm x 35cm x 16cm). This forms part of a more straightforward pricing structure, which we summarise for you below.

The following guidelines should help you calculate your postage and avoid unexpected delivery costs. Please note that prices are subject to change (see 'Royal Mail postage costs' table for the latest prices) but, until further notice, the classification of parcels remains as follows.

Large parcels: Any parcel exceeding just one of the maximum allowed limits for a medium parcel will be considered a large parcel. Large parcels must not exceed 30kg in weight, 1.5m in length or 3m in length and girth combined. Large parcels can only be posted on Parcelforce Worldwide services.

Cylindrical parcels: Any cylindrical or rolled parcel must not exceed 90cm in any dimension, whilst the length of the parcel plus twice the diameter must not exceed 104cm. For example, a parcel that is 80cm long with a diameter of 12cm is allowed [80cm + (2 x 12cm) = 104cm] whilst a parcel that is 85cm long with a diameter of 10cm is not allowed [85cm + (2 x 10cm) = 105cm].
