First post and a commitment
I intend this space to be where I share my notes, mainly on AI. My commitment (to myself) is that these texts will be written exclusively by me.

Print and assemble
Print at 100% / actual size, landscape, duplex with short-edge flip. Disable additional booklet or multiple-pages-per-sheet settings.
Fold each sheet in half, keeping the page order shown. Nest up to four folded sheets per section, then stack the sections in order.
Final page size is derived from the paper and layout. Half of A4 is 148.5 × 210 mm, slightly wider than nominal A5. The binding margin grows with the page count.

Binding estimate
About 8 sections, 32 sheets in total, and a spine around 7.7 mm.
Assumes folio folding: one sheet folded once gives four pages. Spine includes roughly 10% swell from sewing thread.
Astronomy Distance Comparer
Translate astronomical distances into everyday comparisons.
Choose two different objects and a comparison mode.
Scaled comparison
With Earth scaled down to a 5 mm peppercorn:
Jupiter would be 5.5 cm across, about an orange.
Jupiter would sit 247 m, down the street away.
Distances are averages measured from Earth. Pairs that do not include Earth use a straight-line approximation, which astronomy forgives at these magnitudes.
