Here are the standard heights for woodworking machines from "Humanscale 1/2/3"
46 inch = bandsaw table 42 inch = lathe centers 39 inch = radial arm saw table 36 inch = circular saw table (hand feed) 36 inch = workbench 36 inch = sander table 36 inch = shaper table 33 inch = jointer 32 inch = circular saw table (power feed) 24 inch = stool or chair for 36 inch work surfaceNo mention of a thinkness planer. I have mine at 30 inch but find myself bending over. I would try 33 inch, like the jointer, if building another stand.
These standard heights were developed over time to match the Average american male who was 68.8 inches tall in 1973 when Humanscale was published. My apologies to all female woodworkers who have been ignored in the development of so many workplace standards - but read on. I notice that almost every woodworking machine is lower than the above standards, and even seem to be lower than they were 20 years ago. For example my old Rockwell table saw is 35 inches but a new Delta table saw is only 32 inches. This gives great flexibility for those who are shorter than 68.8 inch (male or female) but most folks will want to raise their machines for optimum ergonomics. I have raised my equipment to the standard heights published in "Humanscale" by adding casters. That is still a little low because I am about 70 inches tall, but I am shrinking with age so it should be about perfect just before I expire.
Suggestion for calculating your ideal equipment height"
Ideal Height = Standard Height x your height / 68.8
This method is based on the assumption that our bodies are proportioned to our height - ie short people have shorter arms and legs, tall people have long ones. This is usually true.
