Measure your back, from one side to the other side (where the side seam of a tight fitting garment would be) at the level right below your breast. The pad size of the splint is the most important measurement. You do not want the pad of the splint to be too big. If it rests on the front of your belly it does not allow much room to reposition your muscles together. You also do not want the pad to be too small or you will have trouble attaching the elastic arms of the splint. The pad should be resting on your sides in the location where the side seam of a garment would be.


    Measure the circumference of your body over your belly button where your belly is the largest. Measure in the evening when your belly is the largest. Your muscles should be relaxed when you measure. Waist size does not determine belly size.


    Measure the distance between the bottom of your sternum to your belly button. If it is 6 inches or less than a short torso splint would be good for you. A short torso splint is also good for children Many clients wear two short torsos so they stay in place better.. If the measurement is 7 to 9 inches then a regular torso on top and short torso on the bottom will give you the coverage you need. If the measurement is 10 inches and up then two regular torso splints will give you the coverage you need. Besides giving you more coverage so you don't have your belly coming out of the bottom, wearing two splints also helps keep the splints in place better.
