How can I calculate the Sprite Bounds?

I using the Sprite Slicer 2D Asset, And I Need the Sliced Sprite’s Size(not a Extend, Vector3 size). but It doesn’t changing from original sprite’s bound.
How can I calculate the Sprite’s Bound? can using vertices data and mesh renderer

I… solved this myself
don’t even need calculate, it can solve with just renderer.bounds.size It is auto-setting from unity
