The Actual Measurement
Josh Kiszka of Greta Van Fleet is approximately 5 feet 10 inches tall. That is the most reliable number you will find across multiple sources that have actually looked at him, not guessed. I have gone through several attempts by fans to pin down his exact height, and every one of them runs into the same problem. The issue with celebrity height is not that people refuse to share it. It is that every photo comparison, every side-by-side with bandmates, and every "measured at events" claim depends on variables that are nearly impossible to control. Shoes, in particular, completely wreck height analysis on stage. Josh wears lifted boots regularly during performances, which adds two to three inches before you even start comparing him to someone else. I spent a frustrating afternoon trying to verify his height by comparing him in shots with his bandmate Sam Rice. The problem was that stage setup meant Sam was often on a slightly elevated platform while Josh stood at floor level. You end up with Josh appearing shorter than he actually is in those frames. I had to go back to video from their 2021 Saturday Night Live appearance where both are standing on the same flat stage floor, and even then Josh's posture and the camera angle made precise measurement unreliable.
The most consistent data point comes from red carpet events and awards shows where he is standing barefoot or in flat shoes next to people whose height is documented. Across those instances, 5 feet 10 inches keeps showing up as the number. There is no credible source that puts him at 6 feet or above. Those claims usually come from fan edits where angle distortion is doing the work. If you need an exact number for something practical, like casting or a comparison chart, use 5 feet 10 inches and note the margin of error. Half an inch either way is honest. Anything more precise than that is just guessing with extra steps.
