If two organisms are in the same phylum what other classification do they share

If two organisms are in the same Phylum they are also in the same Kingdom and Domain.  

The domain is the higher level of classification and it consists of three groups: Archaea, Bacteria, and Eukarya. Kingdom is the second highest level of classification and most often is divided into Animalia, Plantae, Fungi, Protista, Archaea/Archaeabacteria, and Bacteria/Eubacteria.
Below the phylum, there are a class, order, family, genus and species.

Centimeters would be the most accurate tool to measure with
