Being a graphic designer or a business owner, if you want to create eye-catching business cards, the first and the most important step is to determine that which size you should work with. You should also take care of its dimensions. Most of the time, Adobe Photoshop is recommended to create a business card. However, you can use any software available on your computers.
The best size is about 350 dots per inch (DP). The standard size of a business card is at least 3.2 x 2”. That is a perfect size. If bleeds are being used, you should go with 3.6 x 2.1 inches. This is because the area of a bleed is ⅛ inches extra. This space is for element designing and or the backgrounds that have extended beyond the size of your business cards.
