The human is not to scale if that's the Webb telescope.

I think the height is there, but the human seems otherwise out of proportion. He seems to wide, which gives the illusion that he is shorter. And his head is too big, which again makes him look younger/smaller, more cartoonish. I think this is from a stock cartoon character rather than a real person.

I measured the mirror - top to bottom - as 304 pixels and the human as 86 pixels. This makes the human 1.83 meters given a mirror diameter of 6.5 meters. So it is to scale.

  Where is this replica located? Is it open to the public?

    I don't know where it is currently, but according to this 2008 article it was on a world tour at that time. https://phys.org/news/2008-07-james-webb-space-telescope-full-scale.html https://phys.org/news/2008-07-james-webb-space-telescope-ful...

    I recall seeing a full-sized mockup of the James Webb at the South by Southwest about ten years ago. It was accompanied by a small traveling exhibit about the mission and some folks from a NASA (or Northrup?) education team to answer questions. They had been taking it to cities and museums across the country. Not sure where it is now or if there are multiple full-sized mockups, but I wouldn't be surprised if one ends up in the public collection at Udvar-Hazy Smithsonian Annex where many big NASA toys end up.

  6.5 m across 5 hexes. The human is maybe 1.25 hexes tall. About 1.6m or 5'3". That's a dry short adult human.

It definitely is. 6.5m diameter of the mirror only on JSWT and 2.4 of Hubble.
