Mirror Math: Newsletter Challenge (09/06/05)

Posted September 06, 2005 7:00 AM

The question as it appears in the 09/06 edition of Specs & Techs from GlobalSpec:

Fall is coming, time to start in with those home projects again! You had promised your daughter that redecorating her room would be top on the list. While out shopping for some shelves, picture frames, etc. she announces she also wants a full-length mirror. She says, "Dad, I'm 5'1" now and I want to be able to see myself head-to-toe; so it'll have to be at least as tall as I am now, plus a little extra for when I grow." Realistically, what does the height of the mirror need to be?

68 inches

That should cover her for the short term and the rest of her life unless she is above the 95% in in the US.

30.5 inches right now....

09/07/2005 10:04 AM

Right now, if the mirror is hung at the correct height, she would need a mirror 30.5" tall. For every inch of expected growth, she would need an additional 1/2" of mirror. However, she would periodically have to rehang the mirror to get it at the right height for her eyes (which would also be higher off the floor. Assuming she will reach a height of 5'8", and allowing for not having to rehang the mirror, I would get her a 41" mirror. Throw in a couple of inches for a hat, heels, etc. and make it an even 48"!

Re: Mirror Problem

I need to get her a mirror as tall as her i.e 5"1' Any additional height she seems to have either through growth or dress-up then all she needs to do is to walk back (readjusting her distance to the mirror) to see her properly again.

Half the height at any time

09/08/2005 4:04 PM

The mirror needs to be atleast half the height of a person. The top edge of the mirror should be exactly half way between her eye level and top of her head. If she does that, no matter how close or far from the mirror she stands she'll be able to see her complete image.

Realistically (as the question states) the mirror has to be of a size commonly found and sold as a full-length mirror in your favorite store...your daughter can adjust!

Why use a mirror, anyway?

09/28/2005 11:48 AM

IMHO, the best size that will fit her, is the one which is commonly avaliable @ Lowe's or Home Depot.

All variables considered....

You need to buy your daughter the biggest full length mirror that is available. When her friends come over, they'll tell her that her daddy loves her more than their daddy because he's so generous. She'll have a higher opinion of herself, all other things being equal. This will lead her to express confidence and choose a more loving mate when she's older. Daddy's genes will get passed on to a better family. Then it will eventually happen all over again. What does a girl use more than her mirror?

Math Mirror

10/03/2005 11:58 PM

I think the best idea to solve this problem is to have someone to design a sliding mirror that can slide up to maximum 12 feet tall (I wonder if there is anyone with that height in this world). It can be design using 2 or 3 sliding mirror connected together with manual sliding or in automatic sliding just like the telescopic idea. Since technology is so advance, I thinks it is possible even with remote control. If someone design this mirror don't forget to put my name in it.

She needs a mirror which must be half the height of herself.... So, around 2'65" to 2'7" feet height mirror is needed and no problem if she grows a little bit more....
