Choosing the right postage stamp for mailing an A4 envelope can be confusing. There are many factors to consider, like envelope weight, destination, mail service, and size. This comprehensive guide will walk you through everything you need to know about picking the proper postage for an A4 envelope.
What is an A4 Envelope?
An A4 envelope is a standard paper envelope sized to hold A4 paper, which is 210mm x 297mm. A4 is the standard paper size used in most of the world outside of North America. Some key facts about A4 envelopes:
- Dimensions are approximately 9″ x 12″
- Made to fit standard A4 paper without folding
- Widely used internationally for letters, documents, invoices, etc.
- Common choices for mail include white wove, kraft, colored, windowed, and padded
Knowing the size and type of your A4 envelope is the first step towards choosing the right postage.
Envelope Weight and Postage Classes
The total weight of your A4 envelope including contents determines the postage class and rate. Standard postage classes for A4 envelopes include:
- First Class – For envelopes up to 100g. Fastest service.
- Second Class – For envelopes up to 750g. Slower delivery.
- Large Letter – For thicker envelopes between 100-750g.
Heavier A4 envelopes over 750g may be classified as small packets or parcels with different rate scales.
To determine the postage cost, you’ll need to weigh your sealed A4 envelope on a scale. Then match the weight to the corresponding postage price. Stamps are sold in common denominations so you may need multiple stamps to reach the total value.

FAQs
Can I use regular Letter stamps on an A4 envelope?
You can use regular-sized definitive stamps for postage on an A4 envelope. However, the envelope must weigh 100g or less. Heavier A4 envelopes require Large Letter stamps for the proper postage rate.
What does an underpaid A4 envelope get returned or destroyed?
If an A4 envelope has insufficient postage, Royal Mail will return it to the sender rather than destroying it. Upon return, the recipient can pay the outstanding postage amount before resending.
How can I buy A4 envelope sized stamps?
Royal Mail does not currently offer definitive stamps sized specifically for A4 envelopes. The self-adhesive definitive stamps and Large stamps work well on A4 envelopes of various weights.
Is an A4 envelope the same as a Large Letter?
An A4 envelope is considered a Large Letter for postage purposes if it weighs between 100-750g. Not all Large Letters conform to A4 dimensions. But A4 envelopes in that weight range are treated as Large Letters.
Can I mail an A4 envelope using a postage label?
Yes, self-adhesive postage labels printed with the proper value can be used on A4 envelopes as a substitute for stamps. Ensure the label sticks firmly in the corner.
Conclusion
Choosing the right postage for an A4 envelope depends primarily on the weight and destination. Standard UK envelopes up to 100g need a 1st or 2nd class definitive stamp. Heavier A4 mail requires Large Letter stamps. And international postage rates are understandably higher.
Match the weight of your sealed A4 envelope to the corresponding Royal Mail postage rate. Then apply the proper value using definitive, Large Letter, international, or commemorative stamps as needed. Correct postage will ensure your important A4 envelope is delivered without delay.
