The Globe Theatre was approximately 100 feet in diameter. The design itself was based on the Roman Coliseum, although on a much smaller scale. The stage was raised from 3 to 5 feet from the ground and was supported by large pillars. The depth of most Elizabethan theaters varies from 20 feet wide and15 feet deep to 45 - 30 feet. The pit or yard was the area located around the stage. There was no seating in the yard. The commoners crowded around the three sides of the theatre to watch the plays at 1 penny per person. At the main entrance was a crest of Hercules bearing a globe on his shoulders. For more information see here: http://www.globe-theatre.org.uk/globe-theatre-design.
