# Rotating bone changes size

When I rotate a bone, the size of the bone changes. Any idea how to fix this?

• did you rotate the bone in edit mode or pose mode? – David Jul 26 '16 at 21:30
• It looks like the bone's parent is scaled in a single axis, meaning that this bone will appear to change size when rotate against the axis of the parent's scale. – Poyo Jul 26 '16 at 21:33
• @chris I was close. The bone's parent is not scaled, it's the whole armature that's scaled. – Poyo Jul 27 '16 at 2:51
• @chris Reset the scale of the armature by selecting it and pressing Alt+S. – Poyo Jul 27 '16 at 4:31
• Chris, understand that this behavior is normal : your armarture is 2.8 times greater in Z than X or Y. So when things which were in Z come to X or Y, they become thinner. – lemon Jul 27 '16 at 4:34
