Known rectangular footprints keep their physical sides. Other shapes are equal-area squares, not maps. Overlap compares area; it does not prove a physical fit.
A little perspective
1 Planck area and Planck length have approximately the same area.

1 Planck area
A theoretical scale made from physical constants. It is not a proven smallest object or a hard physical limit.
Planck length
A theoretical scale formed from the speed of light, reduced Planck constant and gravitational constant. It is not experimentally established as the smallest possible length. The area and volume are derived mathematical scales.
NIST — 2022 CODATA fundamental constants
The marked area is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares area with area. The records below preserve each value’s basis and caveats.

- Comparing
- Area ↔ Area
- Relative size
- The two selected measurements are approximately equal.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Planck length is labelled theoretical; treat the displayed value as a comparison anchor rather than false precision.
