Which format do you choose? When the time comes to designing your wedding invitations remember that there are no rules. Keep in mind that it’s YOUR day and your invitations should reflect who you are. So let your creativity run free and add your personal touch. You’re guaranteed to make your guests smile. To easily send your invitations (and save money!) we recommend using a standard format that’s easy to ship by mail. You might not want to select a XXL or irregular format because it’d be a shame if your work of art gets damaged on the way to the recipient! You can’t go wrong with the 5x7 format. It’s the standard size of most greeting cards and postcards.
