Thank You Card Calculator — Post-Event Cards
Calculate how many thank you cards you need after your event.
How We Calculate This
This calculator estimates thank you card quantities based on your guests, gift givers, and households.
Formula
- Cards needed = households if known, otherwise the larger of gift-giving households or attending households (each ÷ guests per household)
- Total to order = cards needed + spares (typically 10–20% extra for write-mistakes and late gifts)
- Print cost = total cards × cost per card
- Postage = cards actually sent × postage per card (spares are not posted)
- Grand total = print cost + postage + envelopes
Etiquette is one card per household or couple — not one per head. A couple or family who gave a single joint gift receives a single card. Order ~10–20% more than you estimate to cover handwriting mistakes, last-minute changes and surprise gifts.
Frequently Asked Questions
Everyone who gave a gift, helped organise the event, or attended and you want to show appreciation. For weddings, send to all guests plus anyone who sent a gift but could not attend. Thank you cards are not essential for casual parties but are a lovely touch.
Send within 2-4 weeks of the event. For weddings, the traditional deadline is 3 months, but sooner is better. A prompt thank you feels more genuine. Write and post in batches if the number is large to avoid it becoming overwhelming.
Handwritten notes are always more personal and appreciated. For large numbers (50+), you can print a standard message but add a handwritten personal line to each. A printed card with a personal handwritten addition is perfectly acceptable for any event.
One card per couple or household is standard. Address it to both names. If a family attended, one card addressed to the whole family is fine. Only send separate cards if family members gave separate gifts.
