Diastasis Rehab Splint® & Together Tape™ Sizing


You will need to take three (3) measurements to get your correct size and to determine if you need to wear one or two splints. Most of our clients are now wearing two splints for more belly coverage and so the splints stay in place better.  The three measurements are:

1. 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.

2. 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.

3. 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 8 inches then a regular torso on top and short torso on the bottom will give you the coverage you need. It the measurement is 9 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.

If you do not have a measuring tape, measure with a piece of string and then measure the string with a ruler. Please look at the chart below. It gives your back size and circumference size.

If your circumference size is larger than the range on the chart, then the  elastic arms of the splint need to be longer. You can make them longer by stretching them or adding a longer piece of hook velcro to the hook velcro that is presently there. If they are still not long enough you can get our extenders as a last resort.  The extenders velcro on to the ends of each of the three arms to make them longer. These extenders are ideal during pregnancy so you can wear your same splint during the second and third trimester.  You can put a hem in the extender arms to make them shorter.

After a couple of weeks of doing the exercises your belly will become smaller and the elastic arms of your splint may become longer. Just put a hem in the arms to make them smaller or take the hook velcro piece off at the end of the elastic arm, cut the elastic around 2 inches and then sew the hook velcro back on. Remember, the elastic arms need to attach to the side of the splint. If they are attaching to the back they are too long and the splint will become less effective.

The elastic on the elastic splint arms are very strong. Some clients have a difficult time sleeping in them. That is why we now have the Togetherwear Tank and Splint to sleep in. The tank is made out of loop velcro and the splint attaches to the tank top as it has hook velcro on the pad and the top and bottom elastic arms. What makes it easier to sleep in,  is that the elastic splint arms are a much softer elastic so it is more comfortable to sleep in.  For more information on the tank and splint click here

 Splint Tape Sizing

Sizing for the tape is determined by the size of your diastasis size. You check your diastasis in three places. The size may be different in these three locations.

The size is determined by the location wherever it is the largest.

Small: Diastasis up to 4 fingers wide (6 centimeters if you are using our Diastometer™ to measure)

Medium: Diastasis between 4 and 6 fingers (6 to 8 centimeters)

Large: Diastasis 7 fingers (9 centimeters) or larger
