Slide rule list

On this page I am making an attempt to present all scale layouts that were ever produced. The work is still in progress, so do not be surprised this list is that small.

Tick marks, additional hairlines are not reproduced.

Layouts are desribed in following way: scales listed from top to bottom; scales on slide inside [ and ]; back side (if present) is separated with /. The scale has the name that appear on the rule (there was little consistency between slide rule makers on naming the scales) followed by its "scale ID" by which this scale is known to yet another slide rule emulator. Try to click on a slide rule layout to create virtual slide rule. If this is not working with your browser, try to copy and paste layout description into micro builder.
