Default Mark V in HO scale?

A quick note, I'll try to expand this in a few days if it seems necessary.

To make a long story short, I was trying to explain just how large an Ogre is to a non-gamer, but he is familiar with HO scale trains.

Looking thru lots of material, I did find an unofficial source that gives me a length of 83.67 feet for the Mark V. It also had a visual representation (side view) so I could estimate the height at about 56.4 feet. A "fly-by-the-seat-of-my-pants" estimate for width gives me roughly half of the length.

Since in HO scale 1 foot is represented by 3.5 mm (and there are 25.4 mm to the inch), I ended up with:

Length: about 11.5 inches
Width: about 5.75 inches
Height: 7.75 inches

Wouldn't that look cool on his model train setup?

Thoughts?

Your math matches mine ... it would certainly take up a fair amount of layout space were it built.

If your friend still has trouble thinking of that size, tell him it's the same length as two coupled 40' AAR boxcars.

Are there any pictures comparing the sizes of e.g. HVYs to Abrams?

Unfortunately, I have never seen a HVY compared to an Abrams.

I've got the two drawings that compare the various Ogres to an Abrams. I downloaded them years ago and cannot remember the website or credit the creator.

Does anyone else remember these?

They are likely from Winchell Chung's website, that's where I snagged them.

They show a V, III, II, I and an Abrams, along with a human figure.

Let's math it out. I got out a plastic Mk. V and a HVY to measure with my calipers:

Mk. V = 3.275" long; 1.81" wide (over rear treads); 2.225" tall.

HVY = 1.129" long; .61" wide; .444" tall. So a real world HVY would be 28'-3" long; 15'-3" wide; and 11'-1" tall. So someplace in-between the sizes of an actual German 'Tiger II' and the prototype 'Maus'.

Winchell Chung's artwork states a Mk. V is 25.5 meters long, and a real Abrams is 7.93 meters long (from Wikipedia).

If we use Chung's 25.5 meter length, the SJG plastic Mk. V mini is to a scale of 1:306.58 -- if we instead say it is truly 1:300, than a 'real' Mk. V should be "only" 24.95 meters long.

Going with 1:300 scale still (since that is the accepted and stated goal of the minis), the Abrams would be 1.036" long; .48" wide; and .32" tall. So roughly 90% as long as a HVY, but about 80% as wide and tall.

Winchell's Size comparison chart is part of a larger album where he used a bunch of 3D model work he did a couple years ago to determine sizing.

I'm pretty sure the minis are 1:285 scale.

If that's the actual scale, then a Mk. V is 23.7 meters long ...
