Echo Sizing Guidelines

Please take all measurements over the uncovered liner to be used with the Echo; ensure the liner is properly fitted and in place on the patient’s residual limb prior to obtaining measurements. Take a circumferential measurement at level “A” as noted in the diagram. For transfemoral limbs the measurement is taken 1 ½ ” to 2” below the lowest part of the socket trim line. For transtibial limbs, the measurement is taken ½” to ¾” below the lowest part of the socket trim line.
