Quite a few organisations still process their business correspondence by hand in a mail room, but this proves a daily challenge for their employees. Franking letters is actually a time-consuming job. That is why it is important to know how to frank your letters correctly, because if you don’t do it properly, you run the risk of your mail not being delivered to the proper address. And on top of this, it could cause additional costs.* How many stamps do you need for a domestic letter? How does the franking of a normalised letter work? And what about franking a non-normalised letter? How do you frank a letter for an address abroad? And what is priority and non-priority mail? You can read the answers to all these questions in this blog. ## Bpost mailing prices 2026 Discover the detailed mailing prices for 2026 for individuals and businesses on: - [Priority and non-priority mailing prices 2026](https://www.easypost.eu/en/postal-charges-belgium) - [Mailing prices 2026 for Europe and the rest of the world](https://www.easypost.eu/en/international-mailing-price) - [Registered mail prices 2026](https://www.easypost.eu/en/sending-registered-delivery-letter) - [Mail rates for businesses 2025 vs 2026](https://www.easypost.eu/en/bpost-rates) ## Correctly franking letters in Belgium: how many postage stamps to stick on your letter? Which stamps and how many you should stick on an envelope depends on the weight, the size, the desired delivery date and the destination of your mail. If you already know the weight and size of your mail, it is easy to calculate the costs. ![Sizes for a normalised letter](https://images.storychief.com/account_36355/blog-frankeren-header-afmetingen-omslag_e23c620f8f1a3d5e4cd45201bd5bbc00_800.jpeg)Sizes for a normalised letter## **The size can be normalised or non-normalised.** A normalised letter: - is always rectangular - is at least 140 x 90 mm and at most 235 x 125 mm - weighs at most 50 g and is no thicker than 5 mm. Any letter that deviates from these dimensions is non-normalised and then you have to pay a higher price. Franking a large envelope will thus cost more than franking a small envelope. The overview below shows how many postage stamps you need and what the price is per postage stamp to send your mail within Belgium. The cost of your letter thus depends on the speed of the required delivery: priority mail will be delivered within 1 working day after dispatch and non-priority mail within 3 working days. ![Priority rates bpost 2026](https://images.storychief.com/account_36355/25-6466-easypost-tarieven-eng-08_ee64ec2f92614d0352a56555f6f0cf1b_800.png)Priority rates bpost 2026![Non-priority rates bpost 2026](https://images.storychief.com/account_36355/25-6466-easypost-tarieven-eng-09_fb10774ddf930eaf9d78bb63e2cb9eee_800.png)Non-priority rates bpost 2026## Correctly franking letters for outside Belgium: how many postage stamps should you stick on?
