    Heroic scales vs true scales

    Wargaming and tabletop miniatures are named by figure height, not ratio. A "28 mm" miniature measures 28 mm from the feet to the eyes of a person about 1.8 m tall, so the ratio is 1800 ÷ 28 ≈ 1:64.

    32 mm≈ 1:5636 mm
    54 mm≈ 1:3360 mm

    Model railways use true ratios: HO 1:87, OO 1:76, N 1:160. Military and car kits often use 1:35, 1:24 or 1:43.
