Frequently Asked Questions

What is a drafting scale?

A drafting scale or a scale ruler is an instrument used for measuring and transferring measurements at a fixed ratio on a technical drawing. It is a specialized ruler that typically comes with three sides marked with scale measurements.

What are the uses of a scale ruler?

A scale ruler is used by architects and engineers to turn actual dimensions of structures into scale measurements for technical drawings. It is also used by those reading the plans or blueprints to convert the dimensions of the drawing into the actual size of the structure to be built.

How do I read a blueprint using a scale ruler?

First, find out the scale used for the blueprint, which is usually written on its bottom right corner. Then, locate the appropriate scale on the ruler. Next, align the zero mark of the scale with the start of the length being measured. Read the number that aligns with the end of the length being measured. Right under that number is another number, which will be the number of feet of the actual building’s dimension.

How do I tell if a drafting scale is straight or not?

Use a straight edge and place it next to the drafting scale ruler. If you can close the gap between the two instruments, then the drafting scale is straight.

Engineer scale vs architectural scale: what’s the difference?

An engineering scale has three sides and a total of six scales. Its scales represent decimal fractions of an inch. A three-sided architectural scale comes with 11 scales in total, and a flat architectural scale has 4 scales. Its scales represent feet subdivided into 12ths or 16ths. An engineering scale makes use of decimals, while an architectural scale uses fractions.

Drafting Scales

From huge skyscrapers to museums with intricately designed facades, the minds of architects and engineers seem like amazing places overflowing with a plethora of ideas. These ideas start out in small-scale measurements on blank sheets of drawing paper, which eventually become design plans that serve as references when building life-size structures. Because the drafting scale is a key tool in the design process, Engineer Warehouse offers drafting scales of different kinds that are ideal for construction professionals. 

Since engineers and architects always go back and forth between offices and construction sites, they will love having pocket scales clipped on their belts or placed inside their pockets. To avoid confusion between different calibrations, drafting scales come with different colors, such as red, green, or blue, on their edges. This is for easy color-coding and identifying calibrations. Scales are also available in different units such as metric, imperial, or a combination of the two, so transferring scale measurements at a fixed ratio won’t be difficult. For a convenient selection of scales, some of these feature rotating rods displaying multiple scales. Apart from these, there are many other scales of various kinds from which you can easily choose.
