How much does it cost to mail wedding invitations in the UK?

Short answer

The cost depends on the size, weight and shape of your invitation, and the postage service you choose. UK postage prices change regularly, so check the current rates online or at your local post office before you buy stamps.

Postage for wedding invitations in the UK is worked out by the size and weight of the envelope, not by the number of invitations. A standard square or rectangular card in a standard envelope usually needs a first or second class stamp, but larger cards, thicker paper or anything with extra layers may need more postage.

If you are using a wax seal, the envelope becomes rigid and heavier, so it will likely cost more to send. The same applies to ribbon, charms or any raised embellishment. You can check the exact cost by weighing your complete invitation at a post office or using an online postage calculator.

To keep costs predictable, weigh one fully assembled invitation with all inserts and the seal before you buy stamps. Buy a few extra stamps in case you make a mistake or need to re-send. Also remember that if you are posting abroad, international rates apply and are usually higher than domestic ones.

Postage prices change, so do not rely on old stamps or old advice. Check the current rates on the postal service website or at your local post office before you send anything.
