The passage is 2 cubits (1.0 m; 3.4 ft) wide and 1.17 m (3.8 ft) high for most of its length, but near the chamber there is a step in the floor, after which the passage increases to 1.68 m (5.5 ft) high.[80] Half of the west-wall consists of two layers that have atypically continuous vertical joints. Dormion suggests the entrances to magazines laid here and have been filled in.[152]
The Queen's Chamber is exactly halfway between the north and south faces of the pyramid. It measures 10 cubits (5.2 m; 17.2 ft) north-south, 11 cubits (5.8 m; 18.9 ft) east-west,[153] and has a pointed roof that apexes at 12 cubits (6.3 m; 20.6 ft) tall.[154] At the eastern end of the chamber is a niche 9 cubits (4.7 m; 15.5 ft) high. The original depth of the niche was 2 cubits (1.0 m; 3.4 ft), but it has since been deepened by treasure hunters.
Shafts were discovered in the north and south walls of the Queen's Chamber in 1872 by British engineer Waynman Dixon, who believed shafts similar to those in the King's Chamber must also exist.
