How to Use a Bottom-Up Circular Yoke Calculator

Whether machine knitting or hand knitting, shaping a perfect circular yoke is the most difficult step. The Bottom-Up Circular Yoke Calculator is a professional knitting tool that makes shaping your sweater yoke completely automatic and accurate.

Bottom-Up knitting means you start the sweater at the bottom hem and work your way up to the neckline. In a circular yoke design, the sleeves and body are knit seamlessly in one piece — without any separate seams. This style is perfect for modern sweaters, Fair Isle patterns, and seamless garments.

This calculator helps you calculate total stitches, set yoke depth and shaping distribution, divide decrease rounds evenly, and estimate final neck stitches and neckline width. Just enter a few measurements and the calculator automatically creates a complete stitch plan for you.

Auto Calculation and Manual Customization in One

The calculator automatically calculates Yoke Depth, Armhole Circumference, and Neck Circumference based on your gauge and chest measurements. However, if you prefer, you can manually edit these values to ensure the result is tailored to your pattern and fit.

What Are Underarm Stitches?

Underarm stitches are stitches allocated from the total body stitches based on the chest circumference to create a comfortable armhole.

You place a few stitches — around 8 to 10 percent — for the underarm on stitch holders. These stitches are subtracted from the combined total for both the chest and sleeves. They are necessary to create a comfortable armhole so that the sleeves and body can join smoothly when making the yoke.

Example: If the total cast-on stitches for body and sleeves are 454, set aside 8 to 10 percent for underarm stitches — roughly 36 stitches. These 36 stitches are divided into the front, back, and underarm parts of the sleeves, and are later used to join the sleeves and body in yoke shaping.
