How long should a card message be?
We measured every one of the 1129hand-written example messages in Mojo Greet's writing guides. The answer is narrower than most people expect — and it barely moves from occasion to occasion.
A greeting-card message should be about two short lines — roughly 10 to 20 words. In our corpus of 1129 real card messages the average is 16.7 words (92 characters), the median is 17, and 87% land inside the 10–20 word band. Write two sentences: the wish, then one specific true thing about the person.
How many words is a card message, really?
The striking thing isn't the average — it's how tight the spread is. Eight in ten messages sit between 13 and 20 words. The middle half is tighter still: 15 to 19. Nothing in the corpus runs past 27 words.
If your draft is over 25 words, you've almost certainly written past the good bit. 99% of real messages come in under 25. Cut back to the one thing you actually wanted to say.
Does the occasion change the right length?
Far less than you'd think. Averaged across 22 occasions, the longest and the shortest are only 5.4 words apart — wedding messages run longest at 19.8 words, new job messages shortest at 14.4. Every occasion lands in the same two-line band.
There is no separate word count for a sympathy card or a wedding card. The occasion changes the tone and the words you choose — not how many of them you need.
One sentence or two?
Two. The average message runs 2.1 sentences, and only 13% stop at one. The pattern underneath the number is consistent: the first sentence carries the occasion — the wish, the congratulations, the thank-you — and the second carries the person.
That structure is why 16.7words is enough. A single sentence usually manages only the greeting, which is the part the card's front already says. The second sentence is where the message stops being generic, and it rarely needs to be long: eight or ten words is enough to name one real, specific thing.
What each length actually looks like
Three real messages from the corpus — one from the short end, one at the exact median, one from the longest band. None have been edited.
Happy birthday - go and make a fuss of yourself today.
You're one of the good ones, and I don't say that lightly. Have the day you deserve.
So thrilled for you both. Here's to a marriage full of laughter, adventures, and the quiet ordinary days that turn out to be the best ones.
The longer message isn't warmer — it's just more specific. Adding words only helps when the words add a detail; otherwise the shorter one wins.
How to cut a card message down to length
- Delete the throat-clearing."I just wanted to say" and "I hope you have a" are almost always removable without losing anything.
- Keep one detail, not three. Choose the most specific one. A list reads like a reference; one detail reads like you meant it.
- Don't explain the feeling.Name what they do or what you'll remember and let the reader do the rest.
- Say it out loud.If you run out of breath before the end, it's too long for a card.
- Move the overflow to another format.A photo, a video that plays on open or a one-tap voice note carries what the written message shouldn't.
Questions about card-message length
How long should a greeting-card message be?
About two short lines — roughly 10 to 20 words. Across 1129 real card messages the average is 16.7 words, the median is 17, and 87% land inside that band.
Is a longer card message better?
The data says no. 99% of the messages we measured come in under 25 words, and the single longest is 27. Length isn't what makes a card land — one specific, true detail is.
How many sentences should a card message be?
Two. The average message runs 2.1 sentences and only 13% stop at one — typically a wish or a thank-you, then one specific line about the person.
Does the occasion change how long the message should be?
Less than you would expect. Across 22 occasions the averages span just 5.4 words, from wedding at 19.8 down to new job at 14.4.
What if I have more to say than fits on the card?
Keep the written message short and let another format carry the rest. A Mojo Greet card can also hold a photo, a video that plays on open, or a recorded voice note — all free.
Methodology
We measured all 1129hand-written example messages published in Mojo Greet's greeting-card writing guides. Word counts exclude punctuation; sentence counts split on full stops, question marks and exclamation marks. The per-occasion comparison includes only the 22 occasions with at least 20 messages, so no average rests on a handful of examples. Every figure on this page is computed from the corpus when the page is built, so it can never drift from the source text — and it will move as the corpus grows.
The corpus is a set of example messages written for these guides, not messages collected from senders, so it describes what a well-written card message looks like rather than what the average person types. The full text is published openly at llms-full.txt. You're welcome to cite this study — please link back to this page.
This is the length cut of a wider analysis. The parent study, what makes a good card message, covers second-person voice, opening words and how warmth actually shows up in the text. For the writing method itself, see how to write a greeting card, or pick your occasion in the what-to-write guides.
Two lines is all it takes.
Our free tools are built to that length — short, specific, and about the person.
