How to Assemble Wedding Invitations

Putting together your wedding invitations may sound straightforward, but when you consider a few extra details, from insert order to postage, things can get messy. In this guide we’ll walk through how to assemble your invitation suite step by step and answer the most common questions couples ask when it’s time to mail them.

1. Gather All Your Pieces

Before you start folding and mailing, make sure you have everything you need. A typical invitation suite includes:

• The main invitation card

• An Information Card

• A RSVP card (and envelope, if included)

• Any additional inserts (map/directions, accommodation info, wedding website card)

• Envelopes

• Postage stamps

By having all pieces laid out, you avoid missing something later and you’ll get into an efficient flow when assembling.

2. Insert Cards in the Correct Order

Proper insertion ensures everything looks neat, sits flat, and is easy for your guests to read. Follow this order:

1. Fold the invitation (if required) and then place it into the envelope with the printed side facing you — so when the guest opens it, it’s right side up.
   
   
2. Insert information card(s) next.
   
   
3. Add the RSVP card and its envelope (if separate).
   
   
4. Add any optional inserts (map, accommodations, wedding website info) after the main invitation/reception cards.
   
   
5. Check that nothing is sticking out or uneven.
   
   

Tip: If your invitation has a fold, check that the fold is placed away from the envelope’s opening so it lies flat when opened.

3. Choosing the Right Envelope and Sealing

Selecting the correct envelope size and sealing it carefully will help ensure your invitations arrive looking polished.

• Seal the envelope securely: if you’re having the envelope mailed as is (no extra sleeve), wet the flap or use a glue stick/tape as needed.

• Consider using a return address on the back flap, and a printed or handwritten recipient address on the front.

Tip: If you have heavy inserts (map, accommodations, etc.), consider a slightly larger envelope or reinforce the envelope’s seams so nothing tears or bulges.

4. Addressing the Envelopes & Postage

This is where many couples hit snags. Here are some key points:

• Print or hand-write the guest names and addresses neatly—calligraphy or printed labels add a special touch. You can also have your envelopes professionally printed.

• Weigh a fully assembled invitation (along with all inserts) at a postal counter or with a small scale. If it’s heavier than standard first-class mail, you may need extra postage (additional stamps) or even a “large envelope” rate.

• Place your postage in the upper-right corner of the outer mailing envelope.

• Drop off the invitations at your local post office or mail them in a batch to ensure they begin the journey together.

Tip: To avoid delays or extra postage surprises, it’s wise to mail a sample invitation early and confirm the correct rate.

5. Timing Your Invites

When should you assemble and mail? Here’s a suggested timeline:

• Order 15 weeks before your wedding date (or earlier if you have lots of international guests or custom inserts).

• Once you receive your invitations, set aside a dedicated “assembly” time (1–2 hours typically for 100 invites).

• Mail your invitations about 8–12 weeks before the wedding. This gives guests enough time to RSVP and plan. If you have destination or out-of-town guests, consider 8–10 weeks.

• Set your RSVP deadline 3–4 weeks before your wedding so you can finalize counts, seating, and menu.

FAQs: Answers to Common Wedding Invitation Questions

Q: Do I need an inner envelope and an outer envelope?
A: The inner envelope is a traditional “to the guest” envelope inside a formal suite, often used for addressed guest names only (without full address). The outer envelope is for mailing (with full address and postage). 

Q: What if my invitation has many inserts…will it cost more to mail?
A: Possibly. The weight and thickness determine postal cost. If your suite has heavy cardstock, multiple inserts, or bulky materials (ribbon, wax seals), it may exceed standard letter rates and require extra postage or be classified as a “large envelope.” Always test one assembled invite at the post office to be safe.

Q: How can I keep things organized when assembling 100+ invites?
A: Set up an assembly line: open all outer envelopes, stack invitation cards, reception cards, reply cards, and inserts in separate trays. Work in batches (e.g., 25 at a time) and check each for completeness before sealing. One missing insert can cause re-work later.

Q: What about printing addresses vs. hand-writing?
A: Both are fine — printing address labels or using calligraphy/modern script fonts adds a polished look. Just ensure the text is legible and centered. Use a fine-tip marker or professional printer. For an outer envelope, use a darker ink that contrasts with the envelope color.

Q: What if I change the guest list after I’ve assembled invites?
A: Keep a few blank suites or extra pieces on hand (we suggest ordering a few extras). If you add guests later, you can assemble and mail those separately or combine with others, but make sure you apply the correct postage for that batch.

Final Wedding Invitation Check and Mailing

Before sealing the final batch, run through this checklist:

• All cards (invitation, reception, RSVP, inserts) are included.

• Spellings, addresses, and guest names are correct.

• Envelopes are sealed neatly, with return addresses added.

• Postage has been validated for the weight and size.

• RSVP deadline is clearly visible and manageable for your planning timeline.

Once you’re confident everything looks perfect, it’s time to trust the post office and get those invites on their way!
