Why 'wish you were here' falls flat
I've read hundreds of postcards at this point, both mine and other people's shared in collecting forums, and "wish you were here" shows up more than any other line, usually because the sender panicked with a blank card and thirty seconds before the mailbox closed. It's not wrong exactly, it's just forgettable, the postcard equivalent of writing "nice weather" in a birthday card.
The problem isn't sentiment, it's specificity. A card that could have been written from any beach, at any time, to any person, doesn't give the reader anything to hold onto. The fix is smaller than it sounds: swap the generic line for one real detail from your actual day.
The one detail rule
Here's the system I use on every card now: pick exactly one specific, sensory detail from the day and build two or three sentences around it. Not a summary of the whole trip, just one moment. On a card from Porto last year, instead of describing the whole city, I wrote about a fisherman who sold me a single grilled sardine wrapped in newspaper for one euro, and how it was better than any seafood restaurant I'd tried there.
That kind of detail does two things a generic line can't: it proves you actually experienced the place, and it gives the reader something specific enough to remember you by. A friend later told me she remembered that sardine story two years after I sent it, something that would never have happened with "having a great time."
What to write on a travel postcard
For travel postcards sent home or to friends, aim for one of these three angles instead of a trip summary:
- A small mistake: getting lost, ordering the wrong dish, missing a train by two minutes.
- A sensory detail: a smell, a sound, a specific food, described in one or two sentences.
- A comparison to home: something that made you think of the recipient specifically.
I mailed a card from Reykjavik describing how I mistook a public hot spring's changing room rules and got quietly corrected by an eleven-year-old local, which got a genuine laugh out of the friend who received it, far more than any description of the Northern Lights would have.
What to write to a Postcrossing stranger
For Postcrossing exchanges, always check the recipient's profile first. Most members list specific interests, from cats to trains to a particular country's stamps, and referencing that beats a blind greeting every time. If their profile mentions they collect cards showing local food, describe a dish from your area instead of the weather.
When a profile gives nothing useful, ask a direct, easy question: "what's the best thing you've eaten this month?" or "what's the weather like where you are right now?" Questions work well in the Postcrossing context specifically because some senders do write back through the site's messaging feature, and a question gives them an easy opening.
A postcard only needs to say one true thing well, not everything.
What to write to a pen pal you know
With an ongoing pen pal, the goal shifts from making a strong first impression to continuing a conversation. I write to a woman I met at a Postcrossing meetup in Rotterdam every few weeks, and our cards reference each other constantly: a plant she mentioned struggling with, a recipe I promised to try, a small ongoing joke about her cat's dislike of postcards specifically.
If you're stuck with a regular pen pal, reread their last card before writing back and respond to something specific they said, the same way you would in any real conversation. It keeps the exchange feeling like an actual relationship instead of two people mailing greeting-card filler back and forth.
Handling a blank card and writer's block
When I genuinely can't think of anything, I ask myself three quick questions: what did I eat today, what almost went wrong today, and what's something I noticed that I'd normally forget by tomorrow. One of those three almost always produces a usable sentence within thirty seconds.
It also helps to write the card sooner rather than later. A card written the same day as the moment it describes almost always beats one written from memory a week later, back at the hotel, trying to summarize five days at once. Keep a card and a pen in your bag if you travel often, the way I've started doing since a trip to Kyoto where I wrote three cards standing at a train platform, each one better than anything I'd have written afterward from memory.
A few real examples to steal
Sometimes it's easier to work from real examples than a rulebook. Here are three actual messages I've sent, kept short on purpose:
- From Lisbon, to a friend: "Got hopelessly lost near the Alfama district today and ended up at a tiny bakery with no sign. Ate a pastel de nata still warm from the oven. Worth every wrong turn."
- To a Postcrossing stranger in Finland whose profile mentioned she collects cards with cats: "Saw a cat sleeping on top of a mailbox this morning and thought of your profile immediately. Hope this finds you somewhere warm."
- To my regular pen pal in Rotterdam: "Your fig tree update made me laugh. Mine is doing worse, down to two leaves. Sending encouragement and a card I found at a shop that reminded me of your kitchen."
None of these took more than a minute to write, and none of them are especially clever. What they share is a single real detail each, which is really the entire method described in this guide. If you're still stuck, try copying the structure of one of these three examples with your own detail swapped in, and build from there once it feels more natural.
It's worth mentioning that handwriting itself matters more than people assume. A rushed, barely legible scrawl undercuts even a well-chosen detail, since the recipient has to work to read it before they can enjoy it. I slow down noticeably when writing a postcard compared to a grocery list, treating it closer to the pace of addressing a wedding invitation, and it shows in how often people mention being able to actually read what I sent.
If English isn't the recipient's first language, which comes up constantly with Postcrossing exchanges, keep sentences short and avoid idioms that don't translate cleanly. "Wish you were here" actually translates reasonably well across languages, which might be part of why it persists, but a phrase like "it was a total blast" can land confusingly for a reader working through it with a translation app. Simple, specific, and short beats clever every time a card is crossing a language barrier along with an ocean.
Common Questions
Is it rude to write a short message on a postcard?
No. Postcards have limited space by design, and a short, specific message reads as more genuine than a cramped attempt to fill every line. Three to four sentences is a completely normal length for any postcard.
What if I'm sending a postcard to someone I don't know well?
Keep it light and specific rather than personal. Describe one thing you saw or tasted that day, or ask a simple question tied to their interests if you know anything about them, the way Postcrossing profiles often provide.
Should I write in pen or pencil on a postcard?
Pen, always, for anything going through the mail. Pencil smudges easily during sorting and transit, and ink also holds up far better for anyone who keeps the card for years afterward.
Is it okay to write the same message on multiple postcards?
It's fine for logistics, like a form message for a mass mailing, but for personal cards to friends, family, or Postcrossing partners, a repeated generic line is usually noticeable and reads as an afterthought rather than a real message.
The Takeaway
What to write on a postcard rarely needs to be clever. It needs to be specific: one smell, one food, one small mistake, one direct question. A three-sentence card about something that actually happened beats a five-sentence card full of generic warmth every time. Pick up whatever postcard is nearest to you right now and write three real sentences about your actual day before you second-guess it.
