Flower Stamps for Invitations: Designs and Postage Types
Choose invitation stamps in two steps: check the postage your finished envelope needs, then choose a floral design within the suitable options. A flower illustration does not tell you whether a stamp carries the domestic one-ounce or two-ounce letter value.
This guide compares three designs in our Flower stamp collection for invitations mailed within the United States.
Compare the design and the postage type together
| Design | Visual direction | Postage type |
|---|---|---|
| Garden Beauty | Close-up flower photography with a varied garden palette | Domestic one-ounce Forever |
| Mountain Flora | Illustrated wildflowers in purple, orange-red, yellow and pink | Domestic one-ounce Forever |
| Garden Corsage | A photographed floral corsage with soft peach and pink tones | Two Ounce |
Use color as a starting point. Garden Beauty gives you several floral photographs; Mountain Flora offers individual wildflowers; Garden Corsage presents an arranged corsage. Compare the actual stamp images with your stationery before ordering, especially if you want to coordinate a particular color.
What does Two Ounce mean?
Garden Corsage was issued at the two-ounce letter rate, as documented in the USPS Garden Corsage announcement. It should not be treated as having the same postage value as a standard domestic one-ounce Forever stamp.
A heavier invitation may call for the two-ounce value, but weight is only part of the decision. Two Ounce does not mean every oversized, rigid or decorated envelope is covered. Confirm the complete mailpiece’s requirements before applying stamps.
USPS considers weight, dimensions and shape when determining postage. Square or rigid envelopes, uneven contents and some decorative closures can require additional postage. See the USPS First-Class Mail guidance and have an unusual invitation checked before mailing the batch.
Make one complete sample invitation
Assemble the invitation exactly as you intend to send it, including the envelope, enclosure cards, ribbon or other decorations. Weigh and measure this finished sample. An empty envelope or a loose invitation card will not give you the same result.
If the suite contains a return envelope, distinguish the two journeys. The return envelope contributes weight while it travels inside your invitation; if you also provide return postage, it later becomes a separate mailpiece with its own requirements.
For example, 60 invitation envelopes with 60 pre-stamped reply envelopes mean two sets of postage to plan. The outgoing suite and the returned reply may need different stamp types. That is a mailing-count example, not a promise that 120 identical stamps will be sufficient.
Count addresses and read the package options
Count the envelopes you will actually send rather than the number of guests. A couple receiving one invitation usually represents one outgoing envelope. Keep a separate count for replies, thank-you notes and any overseas addresses.
Our Garden Beauty and Mountain Flora listings currently use booklet options; Garden Corsage uses sheet options. Check the selector rather than assuming all three products arrive in the same format. The options were reviewed on September 18, 2026 and should be checked again when ordering.
- 5 units of 20 stamps contain 100 stamps.
- 15 units of 20 contain 300 stamps.
- 50 units of 20 contain 1,000 stamps.
The physical unit may be a booklet or a sheet, depending on the listing. A cart quantity of two multiplies the selected package, not a single stamp. Record both the selected option and the total stamp count before checkout.
Keep design choices separate from postage decisions
A heavier envelope does not require you to abandon your preferred color scheme, but it does require sufficient postage. Check your options against the finished sample before choosing a design solely for its appearance. Do not assume an older floral design has expired simply because a more recent issue is available.
For other invitation themes, explore our love and wedding stamps. Review current product options and the shipping policy early enough to leave time for preparing your invitations.
