### Architectural Scales - Notes & Explanations

```The three-sided version of the architect’s
scale has ten separate scales, paired in five
groups of two:
1-inch and 1/2-inch
3/4-inch and 3/8-inch
3/16-inch and 3/32-inch
1 and 1/2-inch and 3-inch
Using the Architect's Scale
• Often used for residential landscape
designs
• Converts measurements to feet and
inches
• Scale ranges for 1/16”=1’ to 3”=1’
• Small marks beyond the 0 point are inch
marks
Reading the Architect’s scale
• Architect’s scale always reads X” = 1’- 0”
For example, ½” = 1’- 0” or 3” = 1’- 0”
Architect’s Scales and Sizes
• 16 Scale = Full Size 12” = 1’- 0”. (standard ruler)
• 3”= 1’- 0” = Quarter Size (divide 3”/12” = ¼)
• 1-1/2” = 1’- 0” = 1/8 size
• 1” = 1’- 0” = 1/12 size
• 3/4” = 1’- 0” = 1/16 size
• 1/2” = 1’- 0” = 1/24 size
• 3/8” = 1’- 0” = 1/32 size
• 1/4” = 1’- 0” = 1/48 size
• 1/8” = 1’- 0” = 1/96 size
• 3/32” = 1’- 0” = 1/128 size
Using Architect’s Scale
Measure using 1/8 scale.
Measured distance equal to 15 feet.
Using the Architect's Scale

inches
