Let Scala Architectural and Engineering Scale change the way you measure printed drawings on the go and at your desk. With fixed and variable scales there is no limit to measuring a printed drawing of any scale, even if the scale is unknown.

FIXED SCALES
If you know the scale of a drawing, place your device on the drawing, scroll to the scale of the printed drawing and watch the chosen scale slide in.

VARIABLE SCALES
If the scale of a drawing is unknown, slide your finger on the variable scale and match the scale of one known element, lock it and use it to measure all elements on that drawing.

MEASURING
Slide the measurement slider in fixed or variable scale modes, along the scale to see the desired measurement displayed.

SECONDARY UNITS
Choose secondary units to be displayed while measuring, to quickly convert between metric, decimal feet and feet and inches.

PRECISION
Control the precision of the measurement units.
