usability - Is there any difference in element minimal sizes on 10 and 24 inch touch screens?

I am developing an application which is supposed to be used on a 24" touch monitor.

There are lots of guides on physical sizes of a touch screen UI elements. All of them are saying that every button/touch-control should be at least 9-11 mm. I think it is a good advice for tablets. But what about 24" touch monitors?

Are minimal dimensions for 10" tablets same for 24" monitors?
