I made my bench 1 metre tall, what are these inch things you talk of

Measure your kitchen counter.
There are years of experience there.
Just use threaded leveling feet. Mcmaster carr has a huge selectionAfter some digging found some charts... but doesn't really make senses. the calculated height is some what way too low or something.... and it's in metrics.... .some of the other charts seems to be confusing.. not sure the exact science, I think 36" is a good height so far. Now going to find an design for individually adjustable legs that will accommodate uneven floors.
