If your goal is to create a traditional theme at your wedding, use standard stationery sizes when it comes to your wedding cards. An outside-the-box approach to your stationery, such as unusually shaped invitations or strangely sized escort cards, will give your wedding a funkier feel. With so many types of wedding cards to use, selecting standard sizes keeps your stationary consistent so that the wedding cards complement one another.
Save-the-date cards are used to give your guests advance notice about the date of your wedding. These cards contain basic information about your wedding, including the bride and groom's names and the date, time and city where the wedding will be held. Save-the-dates are smaller than wedding invitations. Some of the standard card size dimensions for save-the-dates include 6.18 by 4.56 inches, and 4.88 by 3.38 inches, and 5.25 inches by 4.10 inches. Save-the-date cards are usually flat cards, so multiple pages do not add on to the dimensions.
The invitations are the most important cards for your wedding. You can find wedding invitation stationery available in rectangular and square shapes. The standard rectangular invitation has dimensions of 5 by 7 inches, while the standard square invitation has dimensions of 5.25 inches. Wedding invitations are slightly larger than the save-the-date cards because more information must be included on them, such as the formal wedding announcement and exact location of the ceremony and reception.
Response cards are what wedding guests use to RSVP for the event. These are mailed inside of the wedding invitation envelopes and are small cards that are just meant to provide a yes or no response from guests on whether or not they will attend the wedding. The standard size for the response card is 5 by 3.5 inches.
Escort cards, also known as place cards, are important for telling your guests at which table they are to be seated. These cards are necessary unless you choose to have an open seating reception. Escort cards are the smallest of all the wedding cards, and average a standard size of 3.5 by 2 inches.
Menu cards come in a variety of sizes and shapes, from rectangular cards to square cards. These cards are placed on the individual plates or napkins at your wedding reception to let guests know what types of food will be served. Some of the common menu card sizes are 4 by 9.25 inches and 5 by 7 inches.
