Card sizes in one paragraph
Card sizes span the 3.5x2 inch business card, 3x5 and 4x6 note and flat cards, and durable 30mil plastic cards, each built for a different job. Business cards are for networking, 3x5 and 4x6 for notes and invitations, plastic for membership and loyalty. Whichever you choose, build the file to the exact trim with proper bleed and safe margins. 4OVER4 prints every card size on the right stock.
The common card sizes at a glance
Card is a broad word, so start by grouping the sizes by job. The 3.5x2 inch business card is its own category, built to fit a wallet. The 3x5 and 4x6 sizes cover note cards, flat cards, and many invitations, small enough to mail, big enough for a message. And plastic cards, typically 30mil thick at credit-card dimensions, are a durability category all their own.
Once you see cards as jobs rather than numbers, choosing is easy: networking means a business card, a written note means a 3x5 or 4x6, and anything that lives in a wallet long-term means plastic. Order any of them from our business cards category or the greeting cards category.
Business cards: the 3.5x2 standard
The standard business card is 3.5 by 2 inches in the US, a size chosen so it slips into wallets, cardholders, and Rolodex-era habits alike. Sticking to the standard is usually the right call, because it fits the storage people already carry, which means your card is more likely to be kept.
Within that footprint you have real range: stocks from classic to ultra-thick, finishes from matte to soft-touch to foil, and rounded or square corners. If you want to break the mold deliberately, square and custom-shaped cards exist, but treat them as a considered choice, not a default. Browse the full range in the business cards category.
3x5 and 4x6: note cards and flat cards
When a card needs to carry a written message, the 3x5 and 4x6 sizes take over. A note card at 3x5 is compact and personal, ideal for thank-yous, enclosure cards, and short notes. The 4x6 gives more room and doubles as an invitation or announcement size. Both come flat or folded, with folded versions offering four printable panels.
These sizes also mail conveniently, which is why they overlap with invitations and greeting cards. Keep your text inside the safe margin, and if the card folds, plan the panels and reading order. For invitations specifically, our greeting cards range covers flat and folded formats, and the postcard sizes guide is the companion for mailing pieces.
Plastic cards: built to last in a wallet
Some cards have to survive years in a wallet, and paper cannot do that. That is the job of the plastic card, typically 30mil thick at standard credit-card dimensions. The rigidity and waterproof surface make it the format for membership cards, loyalty cards, gift cards, and premium business cards that need to make an impression.
Beyond solid stock, options include 30mil clear plastic cards for a striking see-through look, plus frosted and white finishes. Because plastic is a specialty stock, design with its thickness and finish in mind, and expect a different price and turnaround than paper cards. It is the right choice whenever durability and impression outrank cost.
Setting up a file for any card size
Every card size follows the same file discipline at different dimensions. Build the document at the exact trim size, add 0.125 inch of bleed on every edge, and keep text and logos inside a 0.125 inch safe margin so the blade never clips them. Work in CMYK and place any images at 300 DPI at final size.
Folded cards need their panels measured to the fold layout, and rounded corners want important elements pulled a little further from the edge. Our print-ready file guide and bleed and trim guide cover the exact settings, while the online Designer starts you at the correct size for each card.
How to choose the right card size
Let the purpose lead. Networking and everyday contact means the 3.5x2 business card, because it fits where people keep cards. A written message, an invitation, or a thank-you means 3x5 or 4x6, flat or folded depending on how much you want to say. Anything that must endure daily handling, membership, loyalty, gift, means a 30mil plastic card.
Then let stock and finish refine the choice: premium stocks and foil for a high-end business card, folded panels for a fuller message, clear plastic for a memorable membership card. Use the size chart below and the live pricing panel to compare, then order the card that fits the job.
Order your cards on the right stock
With the size and purpose settled, ordering is quick: choose the product, set the size, stock, quantity, corners, and finish, upload your artwork, and let the free file check confirm it. A classic 3.5x2 business card, a folded 4x6 invitation, or a 30mil clear plastic membership card all come off 4OVER4 presses.

Common Questions
Common questions about card sizes
What are the standard card sizes?
Common card sizes run from the 3.5x2 inch business card up through 3x5 note cards and 4x6 flat or folded cards, plus 30mil plastic cards at credit-card dimensions. Business cards are for networking, 3x5 and 4x6 for notes and invitations, and plastic for membership, loyalty, and gift cards. 4OVER4 prints every one of these sizes on the appropriate stock.
How do I choose the right card size?
Choose by purpose. Networking and everyday contact call for the 3.5x2 business card, because it fits the wallets and cardholders people already carry. A written message, invitation, or thank-you points to a 3x5 or 4x6 card, flat or folded. Anything that must survive daily handling, membership, loyalty, or gift cards, calls for a durable 30mil plastic card.
What does card printing cost and how are prices set?
Cost depends on the card type, size, stock, finish, and quantity, with quantity the biggest lever since the per-unit price drops in bulk. Paper business cards are inexpensive at volume, while plastic cards are a specialty stock that costs more per piece. The 4OVER4 configurator shows the live per-unit price as you set the size, stock, and options.
What sizes, stocks, and finishes are available for cards?
4OVER4 offers the 3.5x2 business card, 3x5 and 4x6 note and flat cards, and 30mil plastic cards including clear, frosted, and white finishes. Stocks range from classic to ultra-thick paper, with finishes like matte, gloss, soft-touch, and foil, plus rounded or square corners. Each product page lists the exact sizes, stocks, and finishes for that card.
What is a 30mil plastic card?
A 30mil plastic card is a rigid, waterproof card about 30 thousandths of an inch thick, at standard credit-card dimensions. Its durability makes it the format for membership cards, loyalty and rewards cards, gift cards, and premium business cards. 4OVER4 offers solid plastic plus clear, frosted, and white finishes, so you can pick between a striking see-through look and a classic opaque card.
How long do cards take to print and ship?
Paper business cards and note cards print quickly and often support same-day or rush lanes, while plastic cards, as a specialty stock, typically take a little longer in production. Read each product's production time and shipping transit separately, especially for a dated event or a mailing. The 4OVER4 configurator shows the timing for your card and quantity before you order.
