Custom flat thank you cards
A flat thank you card is the little note that turns a delivery into a moment, the printed card boutiques and online stores slip into the box to thank a customer by name. It's a single flat panel, printed to your design, made to drop straight into a mailer or gift.
Print them single or double-sided, your logo and message on the front, a discount code, socials or care note on the back, and choose straight or rounded corners. It's custom thank you card printing built for order inserts, not a generic greeting card.
Choose from three board stocks, a smooth 350gsm board, a 300gsm ivory texture, or a 350gsm velvet-touch matt, in matte or gloss, from just 25 cards.

Thank you card sizes (inches and cm)
Wondering what size a thank you card should be? Here are the standard sizes, and you can print any of them, or a custom size, right here:
- 3.5 Ć 5 in (8.9 Ć 12.7 cm) ā the most popular; pocket-sized and fits almost any mailer or box.
- 4 Ć 6 in (10.2 Ć 15.2 cm) ā a common postcard size, roomier for a longer note.
- 4.25 Ć 5.5 in (10.8 Ć 14 cm) ā A2 card size, a classic note proportion.
- 5 Ć 7 in (12.7 Ć 17.8 cm) ā larger, for a feature card or a standout insert.
- 6 Ć 8 in (15.2 Ć 20.3 cm) ā the biggest, for a statement thank-you.
Not sure which fits your packaging? A 3.5 Ć 5 slips into most poly mailers and small boxes; size up for larger cartons or when you want the card to stand out in the unboxing.

Who these are for
Flat thank you cards suit boutiques, D2C and online stores, and craft brands, as order inserts, gift notes and a thank-you in every parcel, from 25 up to bulk.

How do I set up my artwork?
Send your design as an Adobe Illustrator or vector PDF, or a 300dpi PNG, at your chosen size. If you're printing double-sided, send both the front and the back. Extend your background 3mm past the cut line and keep text and logos 3mm inside it.
No design ready? Start from a template in our studio. If your file is low-resolution, there's an optional resolution enhancement for ā¹149, and after you order we send a free proof within 24 hours.
Custom printed box questions
If we missed anything, we are just a call away.
What is the standard thank you card size?
The most popular is 3.5 Ć 5 in (8.9 Ć 12.7 cm), small enough to slip into almost any mailer. Other common sizes are 4 Ć 6, 4.25 Ć 5.5, 5 Ć 7 and 6 Ć 8 in, and you can print any of them or a fully custom size, see the size guide above for the details in inches and cm.
Can I print a custom size?
Yes. Alongside the five standard sizes, we'll print any custom size you need, so if your mailer or box calls for a specific dimension, just tell us and we'll make the card to fit.
What paper stocks and finishes can I choose?
Three board stocks: a smooth 350gsm board, a 300gsm ivory texture, and a 350gsm velvet-touch matt, each available in matte or gloss. The velvet-touch has a soft, tactile feel that suits a considered brand insert.
Can I print on both sides?
Yes. Print single-sided, or double-sided with your logo and message on the front and a discount code, care instructions or socials on the back, a common way brands get more from the card.
Can I use these as packaging inserts or order notes?
Yes, that's exactly what they're made for. They're sized and finished to drop straight into a mailer or box as a thank-you insert or order note, which is why boutiques and online stores use them in every parcel.
Can I get straight or rounded corners?
Both. Straight corners give a classic, crisp card; rounded corners feel softer and modern and resist bending at the tips. Pick whichever suits your brand when you order.
What's the minimum order, and how quickly do you ship?
The minimum is 25 cards, with per-unit pricing dropping as quantity rises. After you order we send a free proof within about 24 hours, then dispatch in 3 working days through Bluedart and DTDC.
Do you do foil, spot-UV or thank-you sticker versions?
Yes, on separate pages: spot-UV thank-you cards for a raised gloss, foil thank-you cards for metallic detail, and product labels if you want a thank-you sticker to seal parcels rather than a card.
How much do flat thank you cards cost?
It depends on your size, quantity, stock and finish, so the price is worked out live in the quote form on this page, just add your details for an instant figure. There's no single flat rate since every order is printed to your design.
