you could try create centerlines (can crash on complex shapes and donuts etc. ). Clean em up.

Chop by 2. Rotate pieces by 90 and then extend the line both sides by a sufficient large amount.

Line on area, clipper etc. Add length value.

Statistics calculator on length value grouped by object id.

You can get an indication of the width by dividing the area by the circumference.
