As a general rule, an invitation card should include information about who the event is for, the type of event, the date and time of the event and the location. The specific type of event dictates the exact details that are included in the invitation.
Some invitation cards are much more casual than others. A wedding invitation, for example, is much more formal than one for a child's birthday. Still, the basic information remains the same.
Step 1: Specify the guest of honor and the occasion
One of the first things in any invitation is who and what the event is in honor of. It can be a wedding for Bob Jones and Mary Smith, a birthday party for Timmy Duncan or a retirement party for John Dunn.
Step 2: State the date, time and location of the event
Immediately following the information from Step 1, the invitation should indicate when and where the event will take place. Include a map for those who may be unfamiliar with the area.
Step 3: Request a response
At the bottom of the invitation, include an RSVP request for the attendees. This allows the hosts to have an idea of how many people will attend. Include a phone number and email address to which people can respond.
