Architecture drawing scales

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
