Most note cards are 3 inches wide and 5 inches tall. This size is also called “standard” or “business.” It’s a good general size for many purposes, including writing thank you notes, invitations, and cards for most special occasions.

Standard Sizes

There are three standard sizes of note cards: 3 x 5 inches, 4 x 6 inches, and 5 x 7 inches. The most common size is the 4 x 6 inch card, which is the size of a standard index card. 3 x 5 inch cards are usually used for quick notes or reminders, while 5 x 7 inch cards are better for longer messages or more detailed information.

Custom Sizes

Note cards come in a variety of sizes, with the most common being 3-1/2 by 5 inches, 4 by 6 inches and 5 by 7 inches. Other popular sizes include A2 (4-1/4 by 5-1/2 inches), A6 (4-3/4 by 6-1/2 inches) and A7 (5-1/4 by 7-1/4 inches). You can also find note cards that are as large as 8-1/2 by 11 inches or smaller than 3 by 5 inches.

The size you choose will depend on the amount of information you need to include on the card and the look you want to create. If you’re sending a thank you card, for example, a smaller size will suffice. But if you’re sending a greeting card or invitations, you may want to choose a larger size so you have enough room to include all the details.


So, what is the size of a note card? While there is no definitive answer, the average size of a note card is 3.5 inches by 5 inches.
