Flat Thank You Cards

What Is a Flat Thank You Card?

Flat thank you cards are single-panel cards printed full color in 3 sizes, from a 4.25" x 5.5" A2 note up to a 6" x 6" square, on any of 20 stocks. People reach for them to thank customers after a purchase, guests after a wedding or shower, and clients after a project. Because there is no fold, they are quick to design and easy to slide into an envelope or a package. If you would rather the message open up on the inside, the Folded Thank You Cards give you four printable panels, and the flat card sits right beside it as the fast, mailable option.

What Size Should a Flat Thank You Card Be?

The right size comes down to how much you want to say. The 4.25" x 5.5" A2 is the classic note, small enough to tuck into a shipping box yet roomy enough for a logo and a line of thanks. The 5" x 7" gives a photo or a longer message space to breathe. The 6" x 6" square reads almost like a mini poster and stands out on a table or inside a gift. All 3 sizes, both finishes, every ink option and the full stock list are grouped below exactly the way the live configurator presents them, so you know what you can change before you change it. Each size can ship with a matching white wove envelope, so whichever shape you pick still slides into a proper envelope.

Here are a few easy ways to make a flat thank you card feel like more than a formality.

Pick a stock that feels like more

The stock list runs 20 deep. The default 14pt Gloss Cover keeps it clean and cheap, while an uncoated cover gives you a natural, writable surface for a handwritten note, including cream and kraft options made from recycled fiber. Reach for 14pt or 18pt white linen when you want texture you can feel, the metallic pearl stocks in ice, silver, champagne and gold catch the light like foil without the foil price, and the 24pt Ultra Thick Gloss Cover gives the card real heft in the hand. A High-Gloss UV Coating makes a photo or a bold color snap.

Round the corners for a softer edge

A thank you should feel warm, and a rounded corner helps. You can round all four corners at a 1/8" or a 3/8" radius, which takes the formal edge off a card and makes it read a little friendlier. Pair it with an uncoated linen stock and a short handwritten line, and a 4.25" x 5.5" card feels personal rather than mass-produced.

Design it without a designer

Already have your artwork? Skip straight to a press-ready blank instead. Each blank flat thank you card template is built at the real trim size with the 1/8" bleed and safe margin already drawn in, so your design never crowds the cut. Grab the size that matches your order below, drop your art in, and upload.

How Much Do Flat Thank You Cards Cost?

Flat thank you cards start at $19.77 per set of 25, and the per-card price keeps dropping as the quantity climbs across 41 tiers toward 100,000, so a cheap thank you card really comes down to how big a run you order. A run of 100 is $42.84, 500 is $77.99, and 1,000 lands at $148.29, close to 15 cents a card. So how many do you actually need? Drag the slider below to set your count and watch both the set total and the true per-card cost update live, and find the point where one more step up barely moves the budget.

Can You Add Matching Envelopes and Sets?

Yes. A thank you card is only useful if you can mail it, so 4OVER4 offers matching white wove envelopes sized to each card, turned on with a single dropdown. Printing several different designs at once, maybe one for customers and one for wedding guests? Order up to 10 sets in the same job instead of placing separate orders. And before anything prints, you choose how to check the file: go Straight to Production to move fastest, request a Free Online Proof to approve a digital preview, or add a Next Day Hardcopy Proof to hold the real printed stock in your hands first. It is the easiest way to make sure a whole batch lands exactly right.

How Do Flat Thank You Cards Compare to the Rest of the Range?

Flat thank you cards are the value pick when you want a quick, mailable thanks, but they are not your only move. If you are weighing a folded card that opens up, or a premium stock that feels like a gift on its own, it helps to see the trade-off in plain numbers. The chart below lines up flat thank you cards against their closest siblings, including the Velvet Thank You Cards and the corporate-ready Business Thank You Cards, so you can compare the starting price on each before you choose.

How Fast Can You Get Flat Thank You Cards?

Flat thank you cards print on a 3 business day standard turnaround, and when a date sneaks up you can move that to 2-Day, Next-Day or even Same-Day production. Each step buys back time for a set percentage on top of the base price, so you only pay for speed when you actually need it. Same Day orders must be approved by noon EST to ship that day. Compare every turnaround tier in the configurator and see exactly what the rush adds before you pick, backed by the fact that 99.8% of our orders arrive on time and 82% ship early.
