The right handout depends on one thing: what you want the person to do with it. A flyer is for reading, a postcard is for keeping (or mailing), and a rack card is for sitting in a display until someone picks it up. Pick by the job, not by which one looks nicest in a sample pack. Here's the honest comparison — from a shop that prints all three and has no reason to push the pricier one.
The flyer: built to inform, not to survive
A flyer gives you the most room, so it's the right call when you actually have something to explain — an event with details, a menu, a sale with fine print. The trade-off is that it's disposable by nature: people read it and set it down. It works best handed to someone at the exact moment it's relevant, not left to be found later.
The postcard: built to keep, and the only one you can mail
A postcard is small, sturdy, and forces you to one clear message — which is a feature, not a limit. It survives a pocket, it ends up on a fridge, and it's the one format on this list you can actually put in the mail, because it is a mailer. Reach for it when you want a single offer to stick around, or when you're sending to a list of addresses. The catch is the space: one message, done well, and nothing more.
The rack card: built to wait
Tall and narrow, a rack card is made to stand in a display or sit on a counter and be picked up by someone who's already curious — a hotel desk, a waiting room, a partner business's counter. It's the most passive of the three: it only works where it's displayed. But in the right spot, it keeps working for weeks without you standing there.
How to choose
Handing it to people in person and need to explain something — flyer. Want it kept, or mailing it — postcard. Leaving a stack where people browse — rack card.
And the honest part: "gets kept" isn't really a format at all. It's whether the piece gives someone a reason to keep it. A plain postcard with a real offer beats a beautiful flyer with none. If we had to name the one we reprint most, it's the postcard — it does double duty as a handout and a mailer, and people actually hold onto it — but the right answer is whichever one fits what you're trying to do.
Tell us the job and we'll tell you which one. We print all three, so we'd rather get it right than sell you the biggest.
