Transparent Acrylic Cutting Ruler 15×30 cm – Black Markings

Transparent Acrylic Cutting Ruler 15×30 cm

A transparent cutting ruler measuring 15×30 cm, with a full grid and 30, 45 and 60-degree angle lines. The lines and numbers are printed in black, with a dense square grid and half-centimetre lines. The ruler is made of clear acrylic 2.8 mm thick and weighs about 146 grams. This thickness gives the blade of the rotary cutter a stable wall to run along.

This kind of ruler is used in sewing and quilting for measuring, marking and as a guide for a rotary cutter. Being transparent, it lets you see the fabric or pattern paper underneath and line the markings up exactly with the fabric edge, a seam line or an earlier mark.

Common uses

• Cutting squares, rectangles and strips for quilting and patchwork.

• Cutting bias binding and diagonal strips along the 45-degree line.

• Adding an even seam allowance along pattern lines.

• Marking pleat lines, hems and pockets on fabric.

• Squaring the fabric edge before cutting, perpendicular to the selvedge.

Professional tips

• Place the ruler so the marking line sits exactly on the fabric edge, not on the loose, frayed threads.

• When cutting with a rotary cutter, press on the ruler with an open palm, fingers well away from the edge, and cut in one motion away from your body.

• Read the measurement from above, at a right angle to the ruler. Looking from the side shifts the line by a few millimetres.

• Work on a dedicated cutting mat. Cutting on a table damages both the blade and the table.

Common mistakes

• Cutting with scissors right against the edge of the ruler. The scissors chip the acrylic edge.

• Ironing next to or over the ruler. Heat warps acrylic and erases the markings.

• Measuring diagonal strips without using the 45-degree line. Use the angle line printed on the ruler.

• Cleaning with alcohol or solvent. The markings come off. Water and a soft cloth are enough.

How this ruler is different

There are two 15×30 cm cutting rulers on the site. In this ruler the markings are black only, with a dense grid and thin lines, while in the other the lines are yellow and black and it has a hanging hole. Anyone who works mainly on light fabrics and pattern paper will usually prefer the black markings.

All the transparent cutting rulers, in different sizes and marking colours, are in Cutting & Quilting Rulers. For drawing pattern curves see Curve Rulers, and for right angles see Square Rulers.
