Further to my post on scaling Antonia. You can of course go the other way and take a prop that is at real world scale and scale the prop up so that Antonia looks smaller by comparison. Here are a few scale values for props.

 To scale props so that Antonia has a different apparent hight:

 Antonia's hight         Prop needs to      Antonia's hight
 is assumed to be:    be scaled at:        is assumed to be:

 6' 2"                         97.568589          1879.6 mm            
 5' 10"                       103.144038        1778 mm
 5' 8"                         106.177402        1727.2 mm
 5' 7"                        107.762110         1701.8 mm
 5' 6"                        109.394825         1676.4 mm
 5' 5"                        111.078286         1651 mm    
 5' 4"                        112.813973         1625.6 mm
 5' 3"                        114.604652         1600.2 mm
 5' 2"                        116.453075         1574.8 mm
 5'                             120.334768         1524 mm    
 4' 10"                      124.484169         1473.2 mm
 4' 8'                         128.929949         1422.4 mm

Finally, to make V4 the same hight as Antonia, V4 needs to be scaled to 95.556%. Or, to make Antonia the same hight as V4, Antonia needs to be scaled to 104.65%.
