As far as I am aware ALL trolleys have standard measures...so it doesn't make any difference if they're for B-737 or B-747
...there are single trolleys and double trolleys....
Never measure one in all my life to be honest....but I'll try to find out for you who manufacture them soon.
Hope that will help...please...don't ask me to measure one for you....
