Pic size on tubes; Prod wise thinking
 

Hi,

Can someone share his experience on the size of thumbs for a tube. Wich size brings best productivity?

4 thumbs/row size 200x200
or 6 thumbs/row size 120x120

ie does big thumbs give better prod, or smaller thumbs?

This depends on your traffic. I know people who swear by giant thumbs, and others who rather have a ton of small ones. I'd go with 240x180 or so and do 4 per row, or 180x135 with 4 per row and leave myself some space on the right for a skyscraper
