SUGGESTED SIZING GUIDELINES
Here are some general guidelines for choosing the best size for you:
- 55cm: 4'8" to 5'3" (55 cm = 21 in)
- 65cm: 5'3" to 6'0" (65 cm = 25 in)
- 75cm: 6'0" to 6'7" (75 cm = 29 in)
Remember that when sitting on the ball, your knees and hips should approximate a 90 degree angle or slightly higher.
Chart is intended for general guidelines only. Please consult your therapist or trainer for your specific needs. If your height is between the specifications, you may need the larger size if you have long legs or carry extra weight for your height. If there is doubt, a larger ball is recommended because it can be slightly under inflated. Please be aware that due to individual differences and workout preferences the guidelines are only general recommendations. If in doubt or if the ball is intended for sitting consider selecting a larger size exercise ball.
