What is the size of drive belt on a maytag mav2755aww washer?

You can get the OEM belt from someone like sears for $25 dollars plus shipping OR you can go to an automotive store and get a 3L510 (51"Long x 3/8"Wide) for closer to $10. Let me say I work for an industrial supply company. I sell this belt for $8 and its a lot better quality that the one that just came off of the washer.

You can get this at Autozone or any other auto store or you can go to an industrial supplier like:
