Wedding Invitation Cards: Wording, Sizes, and Mailing Guide

Wedding invitation cards do one job: they tell a guest who is hosting, who is getting married, when and where the ceremony happens, and how to reply. Nail those five facts, keep the wording plain, and mail them six to eight weeks out. Everything else (paper weight, letterpress, wax seals, ribbon) is style layered on top, and it matters less than most couples think.

What goes on the card

A traditional suite has a rhythm to it. The main card carries the ceremony details. Anything else gets its own insert, because cramming extra lines onto the invitation makes it look crowded and reads like a flyer.

Wording that holds up

Formal invitation wording is old, and the rules exist to keep things clear rather than fussy.

Size, stock, and printing

A7, which is 5 by 7 inches, is the standard invitation size and the easiest to find envelopes and pockets for. A2 at 4.25 by 5.5 inches suits a small wedding or a casual one. Flat cards feel modern; folded cards give you a second and third panel for directions or a schedule.

Paper weight usually lands between 110 and 130 lb cover stock. Anything thinner feels flimsy in the hand, and guests notice even if they cannot say why. Digital printing is the budget option and looks good on textured stock. Letterpress and foil stamping cost more and are worth it if stationery is a priority for you. Thermography sits in the middle.

How many to order

Count households, not heads. A family of five gets one envelope. Then add 10 to 15 percent for last minute additions, calligraphy mistakes, and the one you spill coffee on. Stationers often have minimums of 25 or 50, so a 60 guest wedding may end up ordering more than it needs.

Timeline that works

  1. Save the dates go out 6 to 12 months ahead, earlier for a destination wedding or a holiday weekend.
  2. Order invitations 4 to 5 months before the wedding so proofs and reprints have room.
  3. Approve the proof in writing, and read it out loud once. Typos hide in names.
  4. Mail 6 to 8 weeks before the date, or 10 to 12 weeks for a destination wedding.
  5. Set the RSVP deadline 3 to 4 weeks out, which is when caterers want final numbers.

Mailing without drama

Take one fully assembled envelope to the post office and have it weighed before you buy stamps in bulk. Square envelopes and heavy or rigid suites often need nonmachinable postage, which costs more and arrives slower. Wax seals and ribbon can jam sorting machines, so ask for hand cancelling. Put your return address on the back flap, and double check that every envelope has the right city and ZIP.

Paper, digital, or both

A paper invitation still signals that the event is formal. Many couples send paper to older relatives and out of town guests, then email everyone else, or send paper to all and collect replies online. Either way, keep the details identical across both, because half your guests will check the website the night before.

Where the money goes

Per suite costs vary hugely by printing method, but people forget the add-ons: calligraphy or printed addressing, assembly, extra postage, and the reply card envelopes. Postage alone can run 10 to 20 percent of the stationery budget. Cutting the insert cards is usually the easiest way to save without the invitation looking cheap.
