Direct answer
Count invitations by mailing household rather than by guest, then add a modest cushion for address mistakes, late additions and keepsakes. A practical extra amount is often around five to ten percent, adjusted to the size and certainty of the guest list.
Count mailing destinations
A couple or family at one address usually needs one invitation unless the host wants separate keepsakes. Build the guest list with names and addresses first so the count reflects actual envelopes rather than total attendance.
Add extras with a purpose
Extras can cover a damaged card, addressing error, newly remembered guest or copy for the parents-to-be. Very small showers may need two or three extras; a larger list may justify a percentage-based cushion.
Recheck before checkout
Confirm the final guest count, proof the design and review the current order quantity choices on Zazzle. This site does not display live pricing or package quantities because those can change on the exact product page.
Separate invitation count from guest count
A guest list of sixty people may require far fewer than sixty mailed invitations because couples and households can often share one. Build a list with one row per mailing destination, then note the number of expected guests beside each household. This prevents over-ordering while preserving an accurate attendance estimate.
Send separate invitations when adults at the same address are invited independently or when the host wants each household member to receive a personal copy.
Use a practical cushion
A five-to-ten-percent cushion can cover a damaged card, addressing mistake, late addition or keepsake, but very small lists are better handled with a specific number. Two or three extras may be more useful than calculating a percentage for a shower with twenty mailing addresses.
Check the exact quantity choices
Product quantities and prices can change, so compare the current Zazzle choices after the mailing count is complete. Order from the finished list rather than choosing a round number first and trying to make the guest list fit it.
