A two-week RfC here:
has produced decisive consensus for raising the default thumbnail size on en.WP from 180 to 220px. The RfC was widely advertised and there was little change in overall preferences as the RfC progressed. Many editors would like the increase to be more (including me), say 230px, but in terms of safe, practical decision-making, nothing beats the 80% of participants who found 220px acceptable. This would be a non-controversial and popular action. The yellow-blue graphs half-way down that section show the profile of community opinion from this sample.
Is it possible for a developer to put this into effect?
Thanks in advance.
