I have a number of the excellent Tamiya 1/25 scale models that I have built; a Panther A, Jagdpanther, Tiger I and T34-85. The figures that come in the kits are 72mm tall. The Del Prado WWII Series Panzer Kommander figure is the same size top of base to top of head, so is the Panzerwaffe holding the 88 shell. I display both of these figures with my Tamiya Tiger I. I think treefrog has both figures in stock and on sale.
The larger K&C and TCS figures are about 68mm tall and would be equivalent to a 5'6' Panzerwaffe at 1/25 scale.
I have posted a number of photos of K&C and TCS Panzerwaffe figures with 1/25 Panzers. Click on my name and look through my posts, I think you will find the photos helpfull.
