Twitter Bootstrap text field's height too small?

Question

I am using bootstrap and i find the height of the text field is too small.It\'s like less than 10px.I am wondering if it is small or i made some mistakes.

I used firebug

Answer 1

Yes the total height is 28px because padding & border also add height to that input like this:

height 18px + 
4px padding-top + 
4px padding-bottom + 
1px border-top + 
1px border-bottom = 
Total 28px height
