Engineer’s Scale - 6 different scales Can be identical or different units 1”=20’ Common for ¼ Acre or less 1”=30’ Common for ½ Acre

Factors to Determine Scale: Actual size of structure Amount of detail to be shown Paper size selected Amount of dimensions and notes needed Common practices (company) DH uses 1/8”=1’-0” because print on 11” x 17” Ivory uses 1/4”=1’-0” because use Arch C 24” x 36”
