you can go to a big box hardware store & try out the different height cabinets/tool workbenches...i did this & found the bathroom height cabinets were the right size for me...im only 5' and kitchen cabinets were too high for cutting...i also found legs for a banquet style table turned out to be the right height for my sewing surface...i bought 2 pieces of formica kitchen top & now i have 2 correct height for me surfaces...my friend is 5'8" & these surfaces are way too short for her..so it does make a difference....going to the store i was able to sit, stand and 'test drive' all before making the commitment...
also, i did invest in a 'fatigue mat'...purchased at a chef supply store...that helps when standing for marathon cutting
