# ContSize

> Reference site for shipping container dimensions, weights and capacity, in English, Spanish and Russian, with a French core. Every container figure on ContSize is checked against ISO 668 (read in IS 6566:2001 and GOST R 53350-2009) and 88 published specification sheets of 30 lines, lessors and makers, and carries its status and documents; last read 19 October 2026.

Evidence: 308 documents read, 5,250 figures written out of them; 88 sheets of 30 lines, lessors and makers behind 191 container figures (44 set by ISO 668, 114 confirmed by most sheets, 21 a range, 12 from one sheet). Last checked 2026-10-19.

Statuses: "set by ISO 668"; "N of M sheets agree" (within ±5 mm, ±2 % mass, ±1 % volume); "range lo–hi, N of M sheets print it" (the median of the largest agreeing group); "one sheet". Payload = max gross − tare.
