Abstract
For every couple of Hausdorff functions and verifying some mild assumptions, there exists a compact subset of the Baire space such that the -Hausdorff measure and the -packing measure on are both finite and positive. Such examples are then embedded in any infinite dimensional Banach space to answer positively a question of Fan on the existence of metric spaces with arbitrary scales.
