Is the physics world on a different coordinate system? Physics body scale is wrong

cocos2d-x

I have a sprite with a circle texture, I am trying to make it a physics body. Which intuitively leads me to use this code

auto size = Charecter->getBoundingBox().size;
auto playerMat = PhysicsMaterial(0.1, 1.0, 0.0);
auto phys = PhysicsBody::createCircle(size.width / 2, playerMat);
auto Charecter->setPhysicsBody(phys);

However this code makes the physics body way to small for the sprite. Is the physics world on a scaled coordinate system?

try that;

Character->getContentSize();
