A little perspective
Stonehenge trilithon vs Apollo lunar module: height comparison
The reconstructed height of a Stonehenge trilithon is about 1.04 times the overall height of the Apollo lunar module.
A Stonehenge trilithon is a prehistoric monument feature consisting of two upright stones supporting a horizontal lintel at Stonehenge.
The Apollo lunar module was a two-stage spacecraft used by NASA to land astronauts on the Moon and return them to lunar orbit during the Apollo missions.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. Horizontal rulers compare the selected spans; vertical brackets also identify height on the artwork.
Measurements, assumptions & sources +
Stonehenge trilithon
Approximate reconstructed height: 7.3 m; approximate; range 6.7 m–7.5 m.
A representative great trilithon at Stonehenge reconstructed to approximately 7.3 m high and 6.5 m wide. Fallen, incomplete stones and uncertain original surfaces make the dimensions approximate.
The marked approximate reconstructed height is calibrated. Unmeasured illustration details are representative.
Apollo lunar module
Overall height: 7.04 m; specified.
The Apollo lunar module was about 7.04 m high. The 15,103 kg value is the Apollo 11 lunar module at separation, including descent and ascent stages; mission configurations differed.

Why this measurement?
Why we use 7.3 m
We compare the reconstructed height of a Stonehenge trilithon. This is an estimate; check the notes for its rounding and uncertainty. The recorded range is 6.7 m to 7.5 m.
A representative great trilithon at Stonehenge reconstructed to approximately 7.3 m high and 6.5 m wide. Fallen, incomplete stones and uncertain original surfaces make the dimensions approximate.
