All architecture drawings are drawn to a scale and as described here in great detail, there are set scales that should be used depending on which drawing is being produced, some of which are below:
1:500 (1”=40’0”) – Site plan
1:250 (1”=20’0”) – Site plan (note that 1:250 is not a common metric scale)
1:200 (1/16”=1’0”) – Site plan
1:100 (1/8”=1’0”) – Floor plans, elevations and sections
1:50 (1/4”=1’0”) – Floor plans, elevations and sections
1:20 (3/4”=1’0”) – Room plans, interior elevations
1:10 (1 1/2”=1’0”) – Joinery, component details, construction details
1:5 (3”= 1’0”) – Construction details
