Your postage calculator questions answered


How does your Royal Mail Postage Calculator work?

There are a wide range of services available from Royal Mail and in our Calculator we have opted to calculate those costs for 1st or 2nd Class Domestic Standard Services.

If you want to look at all the Royal Mail costs and options then you can see them here.

There are only three steps in using our calculator.

Step 1: enter how heavy it is; Step 2 enter the type of item; and Step 3 do you want to send it 1st or 2nd class.

If your item is bigger or heavier then you'll need to visit the Royal Mail site. You'll find international shipping and signed for services fully defined there.
