Hi, If the EPSG:4326 scale is 1:136k and EPSG:3857 scale 1:68k I would await less tiles for EPSG:4326, not more. Could there be some error in the formula that estimates the tile count?

Generally speaking, grisets zoom levels are not comparable with each other. Regards, Andrea Aime == GeoServer Professional Services from the experts!

I am generating tiles with GeoWebCache integrated with GeoServer. Can someone explain me why when generating tiles of the same area in EPSG:4326 there are approximately double or triple as many files as in EPSG:900913 (same as EPSG:3857)? Example screenshots are attached for zoom level 12, although it occurs at all levels.
