I’m using a crop pant pattern and want to alter the legs to be full length and boot cut. Does anyone know where to start the taper and how much to add. I’ve done a prelim pattern starting at the patterns “lenghten or shorten” line at the knee. After contiinuing an imaginary line down from the crop original hem line and adding 1 inch to that new hem line side seam, it turns out that the finished width measurement at the new hem line is the same as the “knee”, or just above the knee finished leg width. 9 1/4 inches pant leg front and 10 7/8 inches pant leg back. I read an article saying ow to alter a full leg pant to a crop and it said to take off the same amt on the front and back pattern pieces, so I reversed this procedure. I have no idea how wide a boot leg width should be, I have no such pant in my closet to measure.

The cuff only needs to be wide enough to fit over your boots. Your 19" sounds perfect. Now, boot cut jeans are generally tighter in the thigh and knee then straight leg and definately tighter than cropped pants. You can redraw the seam lines based on your leg measurements plus 2-3" of ease. You can use your existing pattern as a guide if you like. The back will have more fabric and a steeper inseam curve, and the front will be straight and appear longer to match the total linear inches in the back curve. Or you can baste and fit as you go to get the right fit throughout the leg. Basting takes longer and involves alot of ripping but the fit will be perfect. I've made my own jeans and needless to say, they're the best fitting. I didn't wash the denim enough on my first two pair and they actually continued to shrink awhile. They still fit, but are about 3/4" shorter than I planned.
