Are you trying to decide when you should order your wedding invitations? As a general rule of thumb, you should order your invitations at least 4 to 6 weeks before you plan to mail them out. Since you should mail your invitations out at least 6 weeks before the wedding date, you should
order your invitations no later than 10 weeks before your big day. Since you will also need time to address the envelopes, however, you should order your invitations about 12 weeks before your wedding so you can be certain they are ready to go in time.
Since you are working on a tight timeframe and there is always the possibility of making mistakes when addressing envelopes, you should also order extra invitation envelopes as well as extra response card envelopes. This way, you can be certain all of your invitations get out in time
for your guests to make plans and to respond to you in a timely fashion.
