Many spacings are largely uniform, e.g.

to mark these spacings using the
punched out holes and set
measurements of the ruler. On the
short side of the triangle, the
dressmaker’s ruler provides a parallel
guide measuring 6 cm in width and on
the long side, 4cm in width.


The rounded side of the Dressmaker’s Ruler corresponds with the conventional dressmakers square. This form is useful for marking the following curves and pattern designs:

As a further key area of application, the Dressmaker’s Ruler can be used to join up the marked single dots through individual positioning of the ruler once the garment has been tried. This is done by using the curve on the ruler that most neatly joins the marked dots. The ‘Walking Stick’ punch out in the Dressmaker’s Ruler can be used for other basic curves including:

The punched out triangle in the Dressmaker’s Ruler provides three different rounded angles. These different angles are useful for drawing pocket flaps, lapels, collars, and many other tightly curved edges.

A further advantage of the Dressmaker’s Ruler over conventional dressmaker’s squares is its crystal clear transparency, which makes it easier to mark checked or patterned fabric.
