The ruler every sock knitter didn't know they needed.

The Cottonwood Creations Sock Ruler is a beautifully practical 12-inch (30.5 cm) wooden tool designed with sock makers in mind. Slide it into your toe-up sock as you knit to check your length and nail the fit before you commit to the heel — no more guessing, no more frogging.

Both versions feature dual inch and centimeter measurements, an adult shoe size conversion chart
