Perspective changes the picture
Objects closer to a camera can appear larger than objects farther away. If one person is slightly in front of another, the difference in distance can make the lineup look uneven even when the people are standing on the same floor.
Low camera angles can make people look taller, while a camera held above eye level can compress the scene. Wide-angle phone lenses can exaggerate the effect near the edges of a frame.
Posture and footwear matter
People rarely stand in a perfectly neutral pose for a photo. Someone may lean, bend one knee, lift their chin, or stand on a step. Hair volume and shoes can also change the apparent top or bottom of the body.
That is why Standii uses the listed height to set the scale and treats the image as a visual reference. The photo helps you recognize the person; the measurement determines where they stand on the wall.
What a fair comparison looks like
A fair visual comparison places the feet on the same baseline, uses a shared scale, and makes the height labels visible. It does not assume that a taller-looking head or a larger image means the person is actually taller.
When a result surprises you, try switching the lineup background, organizing by height, and checking the profile values. The goal is to separate what the camera suggests from what the measurements show.
