How does the percentage system work?

The percentage system uses the body stitch count as 100%. All other measurements are percentages of this: upper arm 33%, wrist 20%, neck 40%. You can also use custom percentages for non-standard proportions.

What are the standard EPS percentages?

Body = 100%, Upper arm = 33%, Wrist = 20%, Neck = 40%. Body length = 25% of chest circumference in cm. Yoke depth = 25% of chest circumference. These produce a classic, well-proportioned sweater.

Can I modify the percentages?

Absolutely. EPS percentages are a starting point. Wider sleeves might use 40% instead of 33%. A wider neckline might use 45-50%. A turtleneck uses the same 40% but adds height. Adjust to fit your body and design.

How do I calculate custom percentages?

Enter your total stitch count and the desired percentage. For example, if your body is 200 stitches and you want the upper arm to be 35%, enter 200 and 35 to get 70 stitches.

Does EPS work for children and babies?

The proportions need slight adjustment. Children have proportionally larger heads (neck 45-50%) and shorter arms. Babies need even larger neck openings. The basic approach still works but adjust the percentages.
