What to look at
Door top above the horizon, crate top below it, head on it: three heights read against one line.
The crate is the unit: everything else can be measured in crates.
The door is 1.2 heads tall; the crate is 0.57 heads. Ratios survive perspective, sizes do not.

Open the reference in the tool to move the camera, change the lens, or add your own objects at real sizes; the share link keeps your version. Draw over the PNG at 30–50% opacity in any app with layers.
