Meet the Twig & Horn Sock Sizing Ruler, designed with your sock knitting needs in mind! Whether you’re working toe up or cuff down, we’ve made it easy to tackle your next sock project with accuracy and precision. Twig & Horn's Sock Sizing Ruler features a center slot opening that’s perfect for measuring as you knit—simply slip the ruler into your sock, peek through the middle, and make sure both the front and back are level and at the same height.

A carefully drilled hole at the top of the ruler enables you to:

Hold stitch markers
Hang the ruler for storage
Attach our Gauge Ruler Keychain
Keep stitch holders close at hand
Work with multiple yarns (e.g. for colorwork); you can tag the colors and tie them through the hole to use as reference
Stay organized! (keep needed tools close at hand)

Intuitive design meets a clean, modern aesthetic with beautiful graphics, cleanly labeled measurements, and shoe sizing guides for your reference. We’ve crafted our ruler using high-quality MDF board made with 100% recycled/recovered, FSC certified wood content. Eco-friendly, yet sturdy in construction, this ruler stands the test of time and holds up to plenty of use without warping or cupping. Designed to store easily inside our Crossbody Tote Cross Body Project Tote, it pairs beautifully with our other knitting tools made from the same material, such as our Square Gauge Ruler, Honeycomb Stitch Markers, and Limited Edition Pom Pom Maker.
