Envelope Sizes
It is vital to know postage costs for different sized wedding envelopes before you start out otherwise you may get a nasty shock when you take your invitations to your local past shop and have to fork out nearly triple the cost in postage than you expected.
Posty Shops and your countries mail service
You will find that your mail service will class letters under 2 categories each with their own size, weight and thickness limits. Typically there is a regular sized letter and an large or oversized letter. We generally want to keep our invitations in the range of a regular sized letter to take advantage of the lowest possible rates.
Letter Dimensions and Postage Costs
Find out your postal services maximum dimensions for a regular letter (or in this case an invitation) and check out what the postage costs are. If your country is not listed here then you can google "mycountriesname postal service" which should return the postal service website you require. Poke around the website for information regarding letter sizing.
