Long ago, traditional furniture was made to "fit" that long-ago society. Many pieces, back then, were shorter (smaller), than they are today. Today, people, in general, are taller and some furniture reflects that increase in size.

There are standards, but who's to say they are right for you.

I often decide what's best for me (and mine), and I sometimes compare that to The Golden Ratio, just to see how "equal" that might be, how that might compare. I most often guage function and pleasing to my eye, more so than to strict standard guide lines, but often those standards satisfy my parameters.

My bathroom vanity cabinet (sink) is about 5" higher, than a standard cabinet/sink. I hate having to bend down to that "standard" low, when using the sink. My shower head is almost 7' high. I hate having to bend low (like at some Hotels, etc.), when showering.
