The published ANSI/SMPTE and ISO film specifications for B&H and N 
perforations on 35mm MP color negative film are:

    Dimension              Aim               Tolerance 
     (INCHES)

    B - Pitch             .1866              + / - .0004
    C - Width             .1100              + / - .0004
    D - Length            .0730              + / - .0004
    E - Margin            .0790              + / - .0020
    G - Offset            .001 MAX

Kodak film manufacturing process control typically holds these 
dimensions well within the allowable tolerances.

Complete information on perforation dimensions and specifications 
can be found in the following standards publications:

    ANSI/SMPTE 93     ISO 491    for 35mm film   
    ANSI/SMPTE 109    ISO 69     for 16mm film
