I am trying label street names using the bing/arcgis online scale 1:1,128, 1:9,028, 1:36,112 and so and so forth and am wondering if the font would get smaller or larger with each zoomed in level. I'm eventually trying to consume in a flex viewer application after caching so I'd like to get it close to "right" as possible. I have the higher traffic streets/highways labeled only at the 1:72k view but am starting to question my font usage around 1:18k til I zoom in closer to the block level, should my street font labeling get larger or smaller?
