“141 x 87 x 48 mm, 590 g (Dimensions & Weight)”

official · K1000 specifications: Wikipedia (figures consistent with widely-cited manual dimensions; original manual PDFs at butkus.org/cameramanuals.org/ManualsLib are scanned images with no extractable text, and no official Pentax/Ricoh museum spec page could be located) · accessed 2026-07-10

“It is 91.4 millimetres (3.6 inches) tall, 143 mm (5.6 in) wide, and 48 mm (1.9 in) deep, and weighs 620 grams (21.9 ounces).”

K1000 dimensions carry medium confidence (archived-source caveat on its fit page).
