The difference in size between business and personal checks also serves to differentiate between the two, but there are no legal requirements for a business check to be larger than a personal check. Business checks are larger so that they can be printed more easily and can be used in a ledger which makes accounting easier. Personal checks are generally handwritten but printed checks are being used more for personal use as well. Personal checks are available in a wide variety of colors and styles and can include a range of images that reflect the personal tastes of the individual.
Personal checks are the size of US paper currency and can easily be fit into your wallet.
