A little perspective
Apollo command and service module vs Squash court: length comparison
The overall docked length of the Apollo command and service module is about 1.13 times the length of a squash court.
The Apollo command and service module was the main spacecraft section used by NASA's Apollo missions to transport astronauts between Earth and lunar orbit.
A squash court is an enclosed room with four walls used for playing the sport of squash.

Apollo command and service module
Overall docked length: 11 m; specified; range 10.9 m–11.1 m.
An Apollo command and service module measured about 11 m from command-module apex to service-propulsion nozzle. The 28,801 kg mass is the Apollo 11 CSM launch configuration, not every mission configuration.

Why this measurement?
Why we use 11 m
We compare the overall docked length of the Apollo command and service module. This value follows a stated specification; check its scope in the notes. The recorded range is 10.9 m to 11.1 m.
An Apollo command and service module measured about 11 m from command-module apex to service-propulsion nozzle. The 28,801 kg mass is the Apollo 11 CSM launch configuration, not every mission configuration.
