Do you struggle with getting ribbing evenly distributed across the garment? I do which is why I’ve created the ribbing calculator. An easy way to calculate the length of ribbing and get a great looking results without having to do the math yourself!
To get a nice looking result I always mark corresponding notches on the ribbing, so if my ribbing length is 85 percent of the garment length, I also make corresponding notch es that are 85 percent of the garment. But that requires some numbers crunching which is why I came up with this calculator.
