Is there a standard check format in the USA?
Legally, a check just needs to have a certain list of things (be an instruction to one's bank to pay a specific amount of money to bearer or to a specific entity, have a date, have a signature, etc.) There are anecdotes around of a guy depositing a junk mail check and it accidentally qualifying as a real check (which he turned into a live show), or of writing a check on a door, cow, or "the shirt off your back". What kind of checks your bank will process is technically up to them. Generally, if you get your blank checks printed up by any reputable firm, they'll have similar information in similar places, as well as the MICR line (the account and routing number in magnetic ink on the bottom) to allow for bank to process the checks with automated equipment. As long as it's a standard size, has the MICR line, and has the information that a check needs, your bank is likely to be fine with it. So, there are some standards, but details like where exactly the name of the bank is, or what font is used, or the like, are up to whoever is printing the check. For details on what standards your bank requires in order to process your checks, you'd have to check with your bank directly. Though, it wouldn't surprise me if they just directed you to their preferred check printer provider, as they know that they accept their check format fine. Though as I said, any reputable check printer makes sure that they meet the standards to get processed by banks without trouble. Unless you're a business that's going to be writing a lot of checks and pay a lot of fees for the privilege, a bank is not likely to want to make exceptions for you for your own custom-printed octagonal checks written in ancient Vulcan.
