How to Assemble & Stuff Wedding Invitations (Step by Step)

Q: What order do you stack a wedding invitation in?

Place the main invitation on the bottom, face up. Stack the enclosure cards on top of it from largest to smallest, also face up, so the smallest card ends up on top. Set the RSVP card, tucked under the flap of its own stamped reply envelope, on top of the stack last. The result is a neat pile a guest can read from the top down, with the invitation as the foundation.

Q: Which way do wedding invitations face in the envelope?

Insert the stacked suite so that when the recipient pulls it out of the envelope and the flap is at the back, the printed side faces them and reads right way up immediately. If you use a double envelope, the inner envelope goes into the outer with the guests' names facing the outer envelope's flap, so they appear as soon as it is opened. The rule of thumb is that everything should face the person opening the envelope.

Q: Does the RSVP card go in its own envelope when assembling?

Yes. The RSVP reply envelope, already addressed back to you and stamped, is placed in the suite with the RSVP card tucked under its flap, not sealed inside it. This keeps the small card from sliding around and signals to the guest exactly how to reply. The whole little unit sits on top of the stack so it is the first thing the guest handles.

Q: How do you seal a large batch of wedding envelopes?

Seal only the outer envelope; the inner envelope is left unsealed by tradition. For a big batch, avoid licking dozens of flaps. A slightly dampened sponge or a small paint roller run along the gum works well, and a glue stick along the flap edge gives a secure hold for heavy suites. Apply postage and any return address before sealing so you are not fighting a sealed stack later.

When the cards and envelopes arrive, there's a correct way to stack and stuff them so the suite looks intentional and reads right the moment a guest opens it. It's genuinely simple once you know the order. Here's the step-by-step, the way everything faces, and the one check that saves you from postage disasters.

The short answer: Stack with the invitation on the bottom (face up), then enclosure cards largest to smallest on top, also face up. Set the RSVP card tucked under the flap of its stamped reply envelope on top of the stack. Slide the stack into the (unsealed) inner envelope so the print faces the back flap, place that into the outer envelope names facing the flap, and seal only the outer. Weigh one finished piece before sealing and stamping the rest.

The stacking order, bottom to top

Everything stacks face up, in size order, so a guest reads the pile naturally from the top down. Here's the exact layering — build it from the bottom up.

Layer	Piece	Notes
Bottom	Main invitation	Face up — the foundation of the stack
↓	Largest enclosure (e.g. details / reception card)	Face up, on top of the invitation
↓	Next enclosure (e.g. directions / accommodations card)	Face up, smaller than the one below
↓	Smaller enclosure (e.g. a reception or website card)	Face up
Top	RSVP card + its stamped reply envelope	RSVP card tucked under the flap of the reply envelope; this unit sits on top

The logic: the invitation is the star, so it anchors the bottom; smaller cards ride on top where they're easy to see; and the RSVP — the one thing you need back — sits on top with its return envelope, so it's the first thing the guest handles. For what each enclosure is, see our guide to wedding invitation insert cards.

Step by step

Lay the invitation down, face up. This is your base. Everything else goes on top of it.
Add enclosures largest to smallest, face up. Details/reception card, then accommodations/directions, then any smaller card. Graduating the sizes keeps each one visible.
Prepare the RSVP unit. Take the stamped, pre-addressed reply envelope and tuck the RSVP card under its flap (don't seal it inside). Place this unit on top of the stack.
Insert into the inner envelope. If using a double envelope, slide the whole stack into the unsealed inner envelope so the printed side faces the back flap — that way it reads right-side-up when pulled out. Leave the inner envelope unsealed.
Insert into the outer envelope. Place the inner envelope into the outer one with the guests' names facing the outer flap, so the names greet the guest the instant they open it. (Single-envelope suite? Just insert the stack itself, print toward the flap.)
Weigh one finished, sealed sample. Before sealing the batch, take one complete piece to the post office, have it weighed and measured, and buy postage to match.
Stamp, then seal the outer envelopes. Apply postage (and confirm the return address is on), then seal only the outer envelope. The inner stays unsealed.

Which way does everything face?

The single rule that prevents 90% of mistakes: everything faces the person opening the envelope. Spelled out:

The card stack goes in printed-side toward the back flap, so when the guest opens the flap and slides the stack out, the invitation is already facing them and right-side-up.
The inner envelope goes into the outer with the guests' names toward the outer flap — names appear first.
The RSVP reply envelope sits with your return address facing up, reinforcing how to reply.

If you're ever unsure, open one as a guest would and check that you can read it without flipping or rotating anything. If you can, you've assembled it correctly.

Weigh before you seal — every time

This is the step couples skip and regret. A full suite — invitation, two or three enclosures, RSVP card and reply envelope — often weighs more than a single stamp covers, and square or oversized envelopes add a non-machinable surcharge on top. Weigh and measure one finished, sealed sample at the post office, then buy postage for that exact weight and shape. It's five minutes that prevents a whole batch coming back marked "insufficient postage." Full details in our postage guide.

Sealing & addressing a big batch

Stuffing a hundred-plus invitations is an assembly line, so set yourself up to do it in passes rather than one envelope at a time:

Address first. Print or write addresses (and the return address) before stuffing — it's far easier on an empty envelope. See how to address wedding envelopes for the formatting.
Stuff in batches. Build all the card stacks first, then insert them all, then seal — a rhythm is faster and more consistent.
Seal without licking. A dampened sponge or a small paint roller along the gum line beats licking dozens of flaps; a glue stick along the edge holds heavier suites securely.
Stamp before the final seal. Apply postage while everything's still easy to handle, then seal only the outer envelopes.

Frequently asked questions

What order do you stack a wedding invitation in?

Invitation on the bottom, face up. Stack enclosures on top largest to smallest, also face up, so the smallest is near the top. Set the RSVP card, tucked under the flap of its stamped reply envelope, on top last. The result reads cleanly from the top down, with the invitation as the foundation.

Which way do wedding invitations face in the envelope?

So that everything faces the person opening the envelope. The card stack goes in printed-side toward the back flap, so it reads right-side-up when pulled out. With a double envelope, the inner goes into the outer with the guests' names facing the outer flap, appearing as soon as it's opened.

Does the RSVP card go in its own envelope when assembling?

Yes — the stamped, pre-addressed reply envelope goes in the suite with the RSVP card tucked under its flap, not sealed inside. This keeps the small card from sliding around and shows the guest exactly how to reply. The unit sits on top of the stack so it's handled first.

Should I weigh wedding invitations before sealing them?

Always weigh one fully assembled, sealed sample at the post office first. The combined weight of the invitation, enclosures, RSVP card and reply envelope often passes one stamp's worth, and square or oversized envelopes add a surcharge. A weighed sample is the only reliable way to avoid "insufficient postage" returns.

How do you seal a large batch of wedding envelopes?

Seal only the outer envelope; the inner stays unsealed by tradition. For a big batch, skip licking — a dampened sponge or small paint roller along the gum works well, and a glue stick gives a secure hold on heavy suites. Apply postage and the return address before sealing.
