Wedding Invitation Cards: Sizes, Wording, and Mail Dates

What a wedding invitation card contains

A wedding invitation card carries six facts: who hosts, who marries, the date, the time, the place, and the reply date. The card is the main piece. Other paper items go in the same envelope.

Standard size is 5 by 7 inches (12.7 by 17.8 cm). That fits an A7 envelope, 5.25 by 7.25 inches. Common paper weight is 110 lb cardstock, about 300 gsm.

Wording order

Read top to bottom:

  1. Host names. "Mr. and Mrs. John Reyes request the pleasure of your company."
  2. Couple names. Use full names on a formal card.
  3. Date and time. Spell out the day and the month. Write "four o'clock in the afternoon."
  4. Place. Venue name, street address, city, state, ZIP code.
  5. Reply line. "R.S.V.P. by May 3" plus a name or address.

Hosts who pay for the wedding appear first. If the couple pays, the couple's names go first.

Formal compared to casual

Formal cards use third person and no contractions. Casual cards use first person: "We're getting married." Both need the same six facts. Body text runs 10 to 12 points. Names run 18 points or larger.

Enclosures

Do not put registry text on the invitation card. Put it on a separate card or a wedding website.

Postage and mailing

USPS prices First-Class Mail by weight and shape. A 2 oz letter costs more than a 1 oz letter. Square envelopes cost more than rectangular ones. Take one assembled invitation to a post office and weigh it. Buy stamps after that.

Ask for hand-canceling at the counter to avoid machine marks on the envelope.
