Reference Question of the Week – 3/4/12

   March 10th, 2012

Measuring eye levelThis was the perfect question to research on a slow Friday afternoon:

How high is eye level?

It turns out, a patron, who was definitely on the short side, wanted to hang a piece of art. However, knowing that her "eye level" was below average, she wanted to know if there was some "golden mean" eye level that would put the art at a pleasing height, no matter how tall the viewer was.

I wasn't entirely sure how to approach this one. Actually, my first thought was to check the Statistical Abstract of the United States just to see if it would give the average height of the citizenry, but I didn't think it gave physical statistics (I checked anyway, and no, it doesn't).

I figured an open web search for phrases like "how high is eye level" would produce all sorts of opinions, and it did. Then we tried a few searches specifically for "how to hang artwork" and found a few other opinions.

The patron seemed uncomfortable with the range of answers - they were all close, but not precise. It seemed like she wanted a single answer, and a reason why that was the answer.

So, we decided to go back to the "average height of a person" approach. A search for average height of a person lead to a Wikipedia article for human height. The section on US citizens cited a Centers for Disease Control report [pdf], which gave me the idea to see if the data was on their website.

A search for average height site:cdc.gov did indeed lead to a CDC page of average body measurements (which was also the source for the report cited by Wikipedia).

Now it was just some quick math:

Average height of women older than 20: 63.8 inches
Average height of men older than 20: 69.4 inches
Sum of the averages: 133.2 inches
Sum divided by 2 to get average average: 66.6 inches*
Average minus 3.5 inches (to get from top of the head down to eye level): 63.1 inches, or 5' 3.1", or 5' 3-1/8"**

So based on the data and our math, average eye level for Americans over 20 is 63.1 inches. She seemed very pleased with this answer - it seemed to me just as arbitrary as the rest we found, but at least our arbitrary figure was backed up by research and math. Regardless, I think that was exactly what she wanted, and she thanked me and left.

This was fun, and I can't help but think she will repeatedly recount this story any time someone comments on the artwork in her house.


*The average person is Satan!

**This was converted using Wolfram|Alpha and the Excel formula =INT(A1) & " ft " & TEXT(MOD(A1,1)*12, "# ??/16 ""in"""). I did this on my own after the fact - the patron though was happy with "5 foot 3 inches, and a little more," to account for the .1 - besides, the 3.5 inches down to eye level was a rough estimation anyway.

    I found this site on Apartment Therapy http://www.apartmenttherapy.com/how-to-hang-you-6174 and this one from an actual gallery http://www.stellersgallery.com/Resources/HowToHang.asp that might be useful in future. Former says 57″, latter says 58″ which looks like it roughly matches all of your hard work!

    Was this patron an artist? Funny how she was so rigid with just this eye level thing, or was she? I’m an artist that has displayed lots of art, and there’s more than meets the eye to this. Such as, was that art hung at an outward/downward angle? How big is the art and the focus of it’s content? What about lighting? What about people sitting in chairs or standing on a higher level? Overall, I have found that art looks best on a wall where it’s balanced with it’s surrounding from various viewpoints. As such, the math helps a little, but it just needs to look good, and you need a good artist’s eye for that. But you know all that and I’m glad you had fun helping her. If you want to research more into this, search for proper placements for big screen TVs, as much of that applies as well.

    Also, you could have just searched for “average eye level”. It’s art, not rocket science. But I know, she wanted rocket science. Funny how people are, you should be proud that you made her day.

    @kalgopia: I’m not sure if she was an artist or what prompted this (although, I would guess not). She was definitely away of the relative differences, but since she knew she couldn’t account for them all, she was just looking for some kind of happy medium that would please the most possible people. Most of the sites we found also said that everything depends on the variables (art, wall, lighting, colors, etc), but I think she just wanted something definite – and it was indeed fun coming up with something.

    I’m the average average!!! (Wait, does this also mean I’m Satan…?)

    I worked at a gallery for five years, and for some reason, the rule was always that the vertical center should be 57″, which I suppose must come from old conventions passed down from museums?
