Refer to the chart at the right to establish the closest match to a standard common scale for project drawings. Recommended Drawing Numbering, Scales and Dimensioning 2 / 3 The recommendation scales* for key architectural drawings are as follows: Site plan – engineering scale 1:20 or similar, depend upon size of site Arch Floor Plan – 1/8” Arch Ceiling Plan – 1/8” These ratios are most appropriate for representing interior and exterior dimensions of rooms, walls, doors, windows and fire protection system. Larger architectural scales in the range of 1-96 to 1-128 ratios are used for commercial projects, such as larger office buildings and factories. Let’s take a closer look at some of the industry standards to better understand the roles of each. Area Survey App - Online calculator app to make an exact plot of a surveyed area - like a room, a property or any 2D shape; Blueprint Letters - Letters used to differentiate blueprint drawings The Big Picture Construction document drawings present distinct design challenges, as well as unique potential. A component drawing at 1:5. After CAD was introduced, since the computer-generated, plotted output provided more clarity, we reduced our text height standard to 3/32″ to gain more real-estate in our drawings, which reduced sheet count in the sets, thereby passing more savings to our clients. Generally, interior elevations are drawn to the same scale as the floor plan(s). A text height no less than 1.8mm should be used. 1-96 to 1-128 Ratios Architectural Scales and Higher.
