What size of shoe do newborns wear?

When I was buying booties and clothes for my new nephew I noticed that most of the time the tags will just say NEWBORN . Their feet grow pretty fast though so if shopping for a baby shower you may want to think about getting a few different sizes to accomidate his or her growth over the months.

measure from back of heel to the tip of their longest toe - size 1 should fit on a baby's foot that measures 3 9/16"; size 1.5 = 3 3/4" ; size 2 = 3 7/8 ; size 2.5 = 4 1/16" ; size 3 = 4 1/4" ; size 3.5 = 4 3/8 ; etc as can be found http://www.kohlscorporation.com/ecom/valueadded/ProductGuides/Shoes_Me asuringTips.htm

I came across the following webpage a while ago - and thought it was pretty interesting way of figureing out what size shoes my children should be wearing - it has come in pretty handy and has proven to be pretty accurate for us!
