Great clean video link thanks, but I cant work out the scale, first it looks like a toy rocket, then from the distance shot it looks huge, like spaceX huge, and then landing it looks quite small again, especially with the lawn sprinklers.
But an impressively smooth landing regardless, and I would imagine maybe harder the smaller the rocket is.
It's much smaller than other suborbital hop vehicles. If it's 6.3 meters, the smallest Starhopper was 18 meters; Blue Shepherd 19 m; China's Hyperbola-2Y 17 m; the Zhuque-3 VTVL test vehicle 18.3 m. Also the Grasshopper from 2012 was 32 m and even 1993's DC-X was 12 m.

You likely weren't being exhaustive in your listing, but I first started watching aerospace development with Armadillo Aerospace, and some of their rockets were much smaller. Their largest one was still shorter than the dc-x.
The important thing about Starhopper was that it had a Raptor engine. And the Falcon 1 had a Merlin engine. They were testing with the engines they intended to put into orbit. Blue Origin are also going with orbital class engines.
I doubt that this rocket has an engine intended for orbit? So it makes me wonder how serious this program is.
Let’s see. 2 cm of grass on top of, say, 10 cm of earth would make the height of a football field 12cm. That would make it as high as about 50 football fields.
Current gen Prius is about 4.5m in length, 1.8m in width, 1.5m in height. "Slightly under 5 x 2 x 1.5m" has been the standard size of a sedan for past few decades.
But an impressively smooth landing regardless, and I would imagine maybe harder the smaller the rocket is.
