Floor plans are commonly produced at 1/ 50th (1 to 50) or 1/100th (1 to 100) of their actual size. Site plans are often drawn at 1/200th (1 to 200) or even 1/500th (1 to 500) of actual size. A scale of 1 to 100 is indicated on a drawing using the code 1:100.
What is the meaning of 1 100 scale?
If the scale of the plan is 1 : 100, this means the real measurements are 100 times longer than they are on the plan. So 1 cm on the plan represents a real length of 100 cm (1 metre)
