Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. A ruler represents the selected distance or a measurement not visible in this view.
A little perspective
12 feet is approximately equal to the dish-to-bus span of the Voyager 1 spacecraft.

12 feet
Length: 3.658 m; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Voyager 1 spacecraft
Approximate dish-to-bus span: 3.66 m; approximate; range 3.5 m–3.8 m.
Voyager 1 had a launch mass of about 721.9 kg and a main dish-to-bus scale of roughly 3.66 m. Its long magnetometer boom and antennas extend beyond that calibrated span.
The marked approximate dish-to-bus span is calibrated. Unmeasured illustration details are representative.

How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 3.66 m for the dish-to-bus span of the Voyager 1 spacecraft; the recorded range is 3.5 m–3.8 m.
- The dish-to-bus span of the Voyager 1 spacecraft: This is an estimate; check the notes for its rounding and uncertainty.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
This comparison follows the selected length only; other dimensions may differ.
