Cross-country skiing provides you and your kids with an effective, low-impact, aerobic and calorie burning workout. To make your family ski outing as fun as possible, you need to make sure your children have the proper equipment, in the right size. Buying or renting skis that are too long or too short for your children will make it hard to them to ski across the snow and have a good time.
Measure your child's height with a tape measure.
Convert the measurement from inches to centimeters by multiplying the number of inches by 2.54.
Add 10 to 30 cm to your child's height to determine her proper ski length for a set of classic style skis. Add 3 to 4 cm to your child's height if you are fitting her for skating-style skis.
Hold the ski next to your child and have her stick her arm straight overhead. A correctly sized classic-style ski will be just below the wrist of the arm extended overhead. Skating skis extended only 3 to 4 cm over your child's head.
