Day 18 ran from an SD card (3.2 cm) to a sofa (2.2 m). The widest gap was round 3, SD Card against Envelope, at 7.5×; the closest call was round 4, Sofa against Floor Lamp, only 1.4× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Step Stool (two-step wooden) vs Passport (ID-3, closed)

    Passport · reference · 12.5 cm
    Step Stool · true height · 50 cm

    4.0× taller than the passport

    This two-step kitchen stool is 50 cm high, roughly half the height of a worktop.

  2. ROUND 2

    Desk (74 cm high, side view) vs Light Bulb (A19, 106 mm envelope)

    Light Bulb · reference · 10.6 cm
    Desk · true height · 74 cm

    7.0× taller than the light bulb

    This desk surface stands 74 cm above the floor; the side view keeps that height easy to judge.

  3. ROUND 3

    SD Card (full-size) vs Envelope (US commercial No. 10)

    Envelope · reference · 24.1 cm
    SD Card · true height · 3.2 cm

    7.5× shorter than the envelope

    A full-size SD card is 32 mm tall; a microSD card is a different format.

  4. ROUND 4

    Sofa (three-seat) vs Floor Lamp (61-inch, fabric shade)

    Floor Lamp · reference · 1.549 m
    Sofa · true length · 2.2 m

    1.4× longer than the floor lamp

    A three-seat sofa is about 2.2 m long.

  5. ROUND 5

    Clothes Hanger (43 cm wooden) vs Fire Hydrant

    Fire Hydrant · reference · 75 cm
    Clothes Hanger · true width · 43 cm

    1.7× shorter than the fire hydrant

    A 43 cm hanger spans the shoulders of a hanging shirt.
