Continue a prop

Your body as the reference

Calibrate a photo of yourself the same way Poster Maker calibrates any image — click two points, tell us the real distance.

Drag, scale, and see it fit

Overlay the prop photo, adjust its transparency, and drag/scale it until it visually matches against your body.

A real measurement, not a guess

Mark any two points on the fitted prop to read off its true size — then send it straight to Poster Maker to print at that exact scale.
