Most Helpful Guy
To answer your question kind of but not really. Height shouldn't matter when you two like each other right? It's common that the girl is shorter than the guy most of the time so don't let stuff like that bother you. Don't worry. Show indications [small or big hints] of flirtation towards him and see how he reacts to them to make sure if he does like you or not. I'm sure he likes you the way you are and if he doesn't, it's his loss. Only way to find out is find a way to make a date with him or do a hangout session hinting it is a date.
