Scale is a big word; there are lots of meanings-many of them designed-charged. Overscaled can be good, fun, dramatic, compelling- or just plain theatrical. Underscaled can ruin a beautifully bold idea before the shovel goes in the ground. Proper scale is classic. This applies to landscapes, fashion, furniture, and rooms; I am sure I am forgetting many others. When things are the right size, you instinctively know it. Any person could tell you if a portrait of a person is badly drawn-we all know faces, and their proportions, as we have had non-stop exposure to the human face. But most could not draw the human face unless they were taught. Unless they learned about scale and proportion. The key idea here-some things can be learned, and can be used as a tool to get your design going somewhere.
So, its a learned skill-to scale up a mortgage survey. A great tool is an engineers scale. It can measure lines in any multiple of 10. In 10 scale, this ruler has 10 short lines representing every inch. I tick is one foot. I like this scale-its easy for me to draw, to see, and to explain. Take that survey to Kinkos, and get it blown up to 1″ equals 10′. They will help you. Then I can help you.
