Law on Square Footage?

So the floor plan of a unit I am considering purchasing states that it is 395 sq ft. and lists certain dimensions.

However, I did a rough measurement and it seems the numbers are a little off, usually short by a few inches (e.g. if the floor plan states 13’3, it is only 13.

I like the place, but is there any cause for renegotiation here?

Can someone tell me what the law is on this?
