As far as I know it isn't possible to define the width of the caption - can you describe your use case for why this is necessary? Typically it will adjust automatically based on the location / size of your interface. Also in general I'd suggest keeping captions relatively short - if you have a large amount of instructional text I'd suggest thinking of other ways to show the information - maybe a link to a section with more details?
as i'm using many navigation bar there are many icons and all have different captions and the length are also different which doesn't look good so i was tiring to make caption background width same
