Same size

The above mail formats shows the different size categories you can choose from when sending Items of identical format. Each size is priced individually, and all items in a mailing/order must, therefore, be the same size. For the largest size, there is a surcharge for items larger than 7 cm thick or more than 25x35,3 cm in size. 

Varying sizes

The price is based on average weight per item. Weigh all items together and divide with the number of items. Find the price per item in pricelist. The only thing you need to remember is to pick out the two largest sizes which has a large format surcharge.

General minimum and maximum dimensions for all mail items

Mail items that are too small can easily be lost, and the minimum size for mail is therefore set to  9 x 14 cm.

If sending extra large items, you must ensure that they are within the maximum dimensions for mail items, with a length of maximum 60 cm and length + width + thickness not exceeding 90 cm.

For larger items, please see our parcel services

The following dimensions apply to rolls:
Minimum length of at least 10 cm. Length + double diameter must be at least 17 cm.
Maximum length of up to 90 cm. Length + double diameter must not exceed 104 cm.

Maximum weight:
2 kg per item

Packing mail

Regardless of the type of mail you are sending, it is important that everything is packed properly and delivered in appropriate load carriers.

If you are sending a large number of items, the way in which you arrange and pack the mail will be extra important. You can get discounts if the mailing is packed as described in the individual discount categories in terms and conditions for mail of identical format.


If you are sending mixed mail, either mail franked with a franking machine or invoiced items of varying sizes, a suitable box may be a practical means of delivering the mail.

  • Suitable when you have a smaller number of items
  • Select a box that suits your mail


Regardless of whether you are sending mail of identical or varying sizes, you can use our red mail trays when handing in your mail.

  • Suitable for envelopes and when you are delivering a smaller number of items without envelope, open or plastic wrapped.


Periodicals and customer magazines are good examples of items suitable for bundles. All bundles must have flat upper and lower sides, so that the bundle’s address side is not bent.

  • Suitable for mail of identical format packed in plastic or without any particular type of wrapping.

How to package and label unaddressed mail and information properly

Check the size

The best size for deliveries in the mailbox is C4 (21 cm x 29.6 cm). Larger items can easily be damaged. The general rule for paper quality is 60 g per m2 or thinner.

Standard formats

Minimum size:              12.5 cm x 14.8 cm
Maximum size:             26 cm x 34 cm
Maximum thickness:     0.5 cm
Maximum weight:         200 g

The items must not be uneven or dented.

Items larger than 26 cm x 34 cm, must be folded to suit our standard size dimension. The fold must be sharp and preferably on the item’s longest side. If the fold is on the item’s shortest side, the item must be within 14.8 cm (minimum) and 21 cm (maximum).

Special formats

The items must always be within 26 cm x 34 cm to fit in the mailbox. If your items are thicker than 0.5 cm, uneven/dented or in a non-rectangular size, this costs extra. The same applies if the items are poly wrapped or if they weigh more than 200 g per item.

There is a limited capacity for items with special format and delivery that is made during an agreed week. Please contact Customer Service on 04045 for further information.

Labelling unaddressed mail

You do not need to label each individual item if you want to deliver unaddressed direct mail with messages of a commercial nature, such as customer magazines, brochures, flyers, etc. The same applies to free newspapers with a significant amount of editorial content.

Messages of a non-commercial nature, for example information from the government and local authorities will also be delivered to households who have opted out of receiving advertising mail. Remember to label these mailings with "Informasjon".

Packing on pallets

The items must be packed on EUR-pallets and labelled for direct transport to our sorting centres. Maximum weight per pallet is 800 kg with a maximum height of 120 cm.

Packing in bundles

When there are too few items for each destination for packing on pallets, or if the items do not cover one layer of a pallet, the items should be packed in bundles of up to 6 kg. Each bundle should be securely strapped. Alternatively, the items can be packed in a cardboard box. Packing in bundles is preferable when your are handing in items to Post offices or Post in Shops.

What if deviations in packing?

If the items are not packed in accordance with the terms and conditions, it could mean they will not be accepted for handing in at the post office. If a deviation is first noticed after the handing in, it can cause a lot of extra work and delayed mailing. Extra costs will be charged.
