Buyer guidesInsert Card Sizes: Mini, Standard, and Bi-Fold Compared
Size is the first decision on every insert card order, and it is driven less by preference than by two practical constraints: how much you need to say, and how much room your packaging actually has. Here is how our core formats stack up.
Mini (2 x 3.5 in)
The smallest standard format, sized like a business card. Best for a single, focused message — a discount code, a loyalty stamp, a QR code. Fits into small-footprint packaging like jewelry boxes and cosmetic pouches where a larger card would need to be folded to fit.
Standard (4 x 6 in)
The default choice for most brands. Enough room for a headline, a short paragraph, and a logo, without overwhelming a typical shipping box or mailer. If you are ordering your first insert card and are not sure what you need, this is the size to start with.
Bi-Fold (8 x 6 in flat, folds to 4 x 6 in)
Four printed panels in the footprint of a Standard card once folded. Use this when your message genuinely needs more space — a care routine, a multi-step setup guide, or a longer brand story — rather than defaulting to it for a message that would fit on one panel.
Die-Cut (custom, up to 5 x 7 in bounding area)
Not a size so much as a shape decision layered on top of any of the above. Choose this when the shape itself is part of the brand impression, independent of how much text the card carries.
| Format | Message length | Typical use |
|---|---|---|
| Mini | One line or code | Loyalty, referral, discount |
| Standard | Headline + short paragraph | Thank-you, general branding |
| Bi-Fold | Multi-step or long-form | Care guides, brand story |
| Die-Cut | Varies | Signature shape branding |
Choosing for your order
When in doubt, write your card copy first and let the word count pick the size — a Standard card stretched too thin with text looks worse than a Mini card with one clean line, and a Bi-Fold with barely any content on three of its four panels wastes the format’s advantage.
