How to Use an Architect's Scale Ruler
Architect scale rulers are used by architects, engineers and construction workers to determine the dimensions of a distance. They use them in building plans or blueprints to calculate equations without using complex and time-consuming math formulas. The blueprints and drawings used are scaled so large areas or structures can fit on paper.
- Determine the scale of the drawing or item that is going to be measured. You can do this by reading the plans for on the drawing. They are usually located in the bottom corner on either the left or right side.
- Determine the correct scale on the scale ruler. For example, 1/8 on the scaler ruler is a scale that changes to 1/8 inch on the drawing plans to 1 foot. This would represent drawing plans that have a scale of 1/8 inch = 1 foot. There are two scales on each side so be careful when reading the scale. One side reads from the right to left, while the other reads left to right.
- Line up the item to be measured with the zero on the scaler ruler. Read the measurement from the scale ruler that is closest to where the item ends. Always round the number down. This number is the whole feet of the item that is measured.
- Round the number down to calculate the whole of the item measures. This measurement equals how many feet the line is at full-scale dimensions.
