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 .
On Javascriptenabled browsers, a
click on a slide rule name will create a slide rule simulation with this
layout.
