   I guess you are talking about font size of subplot tiles?

   You guys probably already know how to update the fonts of subplots created by make_subplots,
   but it isn't probably the best convenient way like your suggestions, i might guess.

   and i also guess i might use the spacing option and margin to adjust the spaces.
   it looks like changing the fonts does not change the spacing??

   For now, i hope this example meets your expectation,
   though it will force you to have the same font for all subplot titles...

   fig = tools.make_subplots(rows=3, cols=2, 
                             subplot_titles=('trace1','trace2','trace3','trace4','trace5','trace6'))
   
   fig.append_trace(trace1, 1, 1)
   fig.append_trace(trace2, 2, 1)
   fig.append_trace(trace3, 3, 1)
   fig.append_trace(trace4, 1, 2)
   fig.append_trace(trace5, 2, 2)
   fig.append_trace(trace6, 3, 2)
   
   for i in fig['layout']['annotations']:
       i['font'] = dict(size=10,color='#ff0000')

   I had no idea. Tried googling for 'plotly subplot title font size' etc. but could not find a solution. I guess the key point here is that subplot titles are annotations.

   for i in fig['layout']['annotations']:
       i['font'] = dict(size=10,color='#ff0000')
   

   Yep, that works. Of course one can simply write i['font']['size'] = 10. Maybe this should be in the example gallery?

   Same, I didn't realize that subplot titles are annotations.

   While it would still be nice to pass this in as a param to make_subplots() during initialization, this solves the problem for now, so I'll close. Thanks!
