Reply or Response Card Dimensions and Sizes
There really isn't a standard size or dimension for a reply card. However, there is a range of sizes that we recommend and they correlate with popular envelope sizes. The chart below displays the envelope size and the corresponding response card size needed. The chart also has a column that tells you how many of that size of response card you can print per piece of standard 8.5" x 11" paper.
Before selecting a reply card dimension, choose your wedding invitation size.
Traditionally the reply card is smaller than the wedding invitation. Choose your wedding invitation size first and then select a response card size that is smaller. This way the response card and corresponding envelope will fit in the wedding invitation envelope.

Postcard Style Reply Card Dimensions
If you choose a postcard style reply card instead of an envelope response card, you don't have to match up the dimensions to an envelope size. You just have to make sure the postcard dimensions are within the postcard guidelines given by the postal service. At the time of this posting, the postcard length must be between 5 and 6 inches. The height must be between 3.5 and 4.25 inches. The paper must also be between .007 and .016 inches thick.
We highly recommend 4.25 x 5.5 inches as your postcard style response card size. This size is within the postal service guidelines. 4 postcards of this size also fit perfectly on an 8.5 x 11 sheet of paper so there is no waste.
